We caution you that assumptions, beliefs, expectations, intentions and projections about future events may and often do vary materially from actual results. Therefore, we cannot assure you that actual results will not differ materially from those expressed or implied by our forward-looking statements.

DESCRIPTION OF OUR DEBT SECURITIES

Our debt securities, consisting of notes, debentures or other evidences of indebtedness, may be issued from time to time in one or more series pursuant to, in the case of senior debt securities, the indenture (the “senior indenture”), dated as of May 3, 2010 between Lennox and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as trustee, and in the case of subordinated debt securities, a subordinated indenture to be entered into between us and a trustee to be named therein. The terms of our debt securities will include those set forth in the indentures and those made a part of the indentures by the Trust Indenture Act of 1939.

Because the following is only a summary of selected provisions of the indentures and the debt securities, it does not contain all information that may be important to you. This summary is not complete and is qualified in its entirety by reference to the base indentures and any supplemental indentures thereto or officer’s certificate or board resolution related thereto. We urge you to read the indentures because the indentures, not this description, define the rights of the holders of the debt securities. A copy of the senior indenture is filed as Exhibit 4.4 to the registration statement of which this prospectus is a part. The subordinated indenture will be substantially in the form filed as Exhibit 4.6 to the registration statement of which this prospectus is a part.

General

The senior debt securities will constitute unsecured and unsubordinated obligations of ours and will rank pari passu with our other unsecured and unsubordinated obligations. The subordinated debt securities will constitute our unsecured and subordinated obligations and will be junior in right of payment to our Senior Indebtedness (including senior debt securities), as described under the heading “Certain Terms of the Subordinated Debt Securities—Subordination.”

We conduct all of our operations through subsidiaries. Consequently, our ability to pay our obligations, including our obligation to pay principal or interest on the debt securities, to pay the debt securities at maturity or upon redemption or to buy the debt securities will depend on our subsidiaries repaying investments and advances we have made to them, and on our subsidiaries’ earnings and their distributing those earnings to us. The debt securities will be effectively subordinated to all obligations (including trade payables and preferred stock obligations) of our subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay any amounts due on the debt securities or to make funds available to us to do so, subject to any guarantee of debt securities as described in a prospectus supplement. Our subsidiaries’ ability to pay dividends or make other payments or advances to us will depend on their operating results and will be subject to applicable laws and contractual restrictions. The indentures generally will not limit our subsidiaries’ ability to enter into other agreements that prohibit or restrict dividends or other payments or advances to us.

The debt securities will be our unsecured obligations. Our secured debt and other secured obligations will be effectively senior to the debt securities to the extent of the value of the assets securing such debt or other obligations.

You should look in the prospectus supplement for any additional or different terms of the debt securities being offered, including the following terms:

5

We may from time to time, without notice to or the consent of the holders of any series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of such series in all respects (or in all respects other than the payment of interest accruing prior to the issue date of such further debt securities or except for the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of such series and have the same terms as to status, redemption or otherwise as the debt securities of such series.

You may present debt securities for exchange and you may present debt securities for transfer in the manner, at the places and subject to the restrictions set forth in the debt securities and the applicable prospectus supplement. We will provide you those services without charge, although you may have to pay any tax or other governmental charge payable in connection with any exchange or transfer, as set forth in the indenture.

6

Debt securities will bear interest at a fixed rate or a floating rate. Debt securities bearing no interest or interest at a rate that at the time of issuance is below the prevailing market rate (original issue discount securities) may be sold at a discount below their stated principal amount. The applicable prospectus supplement relating to any debt securities we issue will include a discussion of certain material U.S. federal income tax consequences relating to ownership of the debt securities, including, if applicable, any material U.S. federal income tax consequences applicable to any debt securities issued or deemed to be issued at a discount.

We may issue debt securities with the principal amount payable on any principal payment date, or the amount of interest payable on any interest payment date, to be determined by reference to one or more currency exchange rates, securities or baskets of securities, commodity prices or indices. You may receive a payment of principal on any principal payment date, or a payment of interest on any interest payment date, that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending on the value on such dates of the applicable currency, security or basket of securities, commodity or index. Information as to the methods for determining the amount of principal or interest payable on any date, the currencies, securities or baskets of securities, commodities or indices to which the amount payable on such date is linked and certain additional tax considerations will be set forth in the applicable prospectus supplement.

Certain Terms of the Senior Debt Securities

Covenants

Unless otherwise indicated in a prospectus supplement, the senior debt securities will not contain any financial or restrictive covenants, including covenants restricting either us or any of our subsidiaries from incurring, issuing, assuming or guarantying any indebtedness secured by a lien on any of our or our subsidiaries’ property or capital stock, or restricting either us or any of our subsidiaries from entering into sale and leaseback transactions.

Consolidation, Merger and Sale of Assets

Unless we indicate otherwise in a prospectus supplement, we may not consolidate with or merge into any other person, in a transaction in which we are not the surviving corporation, or convey, transfer or lease our properties and assets substantially as an entirety to any person, unless:

No Protection in the Event of a Change of Control

Unless otherwise indicated in a prospectus supplement with respect to a particular series of senior debt securities, the senior debt securities will not contain any provisions which may afford holders of the senior debt securities protection in the event we have a change in control or in the event of a highly leveraged transaction (whether or not such transaction results in a change in control).

Events of Default

An event of default for any series of senior debt securities is defined under the senior indenture as being:

7

The default by us under any other debt, including any other series of debt securities, is not a default under the senior indenture.

If an event of default other than an event of default specified in the last two major bullet points above occurs with respect to a series of senior debt securities and is continuing under the senior indenture, then, and in each and every such case, either the trustee or the holders of not less than 25% in aggregate principal amount of such series then outstanding under the senior indenture (each such series voting as a separate class) by written notice to us and to the trustee, if such notice is given by the holders, may, and the trustee at the request of such holders shall, declare the principal amount of and accrued interest, if any, on such senior debt securities to be immediately due and payable.

If an event of default specified in the last two major bullet points above occurs with respect to us and is continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the senior debt securities of all series then outstanding under the senior indenture (treated as one class) may, by written notice to us and to the trustee, if such notice is given by the holders, declare the entire principal amount of, and accrued interest, if any, on each series of senior debt securities then outstanding to be immediately due and payable.

Upon a declaration of acceleration, the principal amount of and accrued interest, if any, on such senior debt securities shall be immediately due and payable. Unless otherwise specified in the prospectus supplement relating to a series of senior debt securities originally issued at a discount, the amount due upon acceleration shall include only the original issue price of the senior debt securities, the amount of original issue discount accrued to the date of acceleration and accrued interest, if any.

8

Upon certain conditions, declarations of acceleration may be rescinded and annulled and past defaults may be waived by the holders of a majority in aggregate principal amount of all the senior debt securities of such series affected by the default, each series voting as a separate class (or, of all the senior debt securities, as the case may be, voting as a single class). Furthermore, subject to various provisions in the senior indenture, the holders of at least a majority in aggregate principal amount of a series of senior debt securities, by notice to the trustee, may waive an existing default or event of default with respect to such senior debt securities and its consequences, except a default in the payment of principal of or interest on such senior debt securities or in respect of a covenant or provision of the senior indenture which cannot be modified or amended without the consent of the holders of each such senior debt security. Upon any such waiver, such default shall cease to exist, and any event of default with respect to such senior debt securities shall be deemed to have been cured, for every purpose of the senior indenture; but no such waiver shall extend to any subsequent or other default or event of default or impair any right consequent thereto. For information as to the waiver of defaults, see “—Modification and Waiver.”

The holders of at least a majority in aggregate principal amount of a series of senior debt securities may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such senior debt securities. However, the trustee may refuse to follow any direction that conflicts with law or the senior indenture, that may involve the trustee in personal liability, or that the trustee determines in good faith may be unduly prejudicial to the rights of holders of such series of senior debt securities not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent with any such direction received from holders of such series of senior debt securities. A holder may not pursue any remedy with respect to the senior indenture or any series of senior debt securities unless:

These limitations, however, do not apply to the right of any holder of a senior debt security to receive payment of the principal of or interest, if any, on such senior debt security, or to bring suit for the enforcement of any such payment, on or after the due date for the senior debt securities, which right shall not be impaired or affected without the consent of the holder.

The senior indenture requires certain of our officers to certify, on or before a fixed date in each year in which any senior debt security is outstanding, as to their knowledge of our compliance with all conditions and covenants under the senior indenture.

Defeasance and Discharge

Defeasance. The term defeasance means we (and to the extent applicable, the guarantors) are discharged from some or all of our obligations under the senior indenture. If we deposit with the trustee under the senior indenture any combination of money or government securities sufficient to make payments on the senior debt securities of a series issued under that indenture on the dates those payments are due, then, at our option, either of the following will occur:

9

If a series of senior debt securities is defeased, the holders of the senior debt securities of that series will not be entitled to the benefits of the senior indenture, except for obligations to register the transfer or exchange of debt securities, replace stolen, lost or mutilated debt securities or maintain paying agencies and hold money for payment in trust. In the case of covenant defeasance, our obligation to pay principal, premium and interest on the senior debt securities of that series will also survive.

Unless we inform you otherwise in the prospectus supplement, we will be required to deliver to the trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the senior debt securities to recognize income, gain or loss for U.S. federal income tax purposes and that the holders would be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and related defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect.

Satisfaction and Discharge. In addition, unless the terms of any series of senior debt securities provide otherwise, we may discharge our obligations (and to the extent applicable, the obligations of the guarantors) with respect to a series of senior debt securities and the senior indenture with respect to such series of senior debt securities when:

With respect to the first and second bullet points, only our obligations to compensate and indemnify the trustee and our right to recover unclaimed money held by the trustee under the senior indenture shall survive. With respect to the third bullet point, certain rights and obligations under the senior indenture (such as our obligation to maintain an office or agency in respect of such senior debt securities, to have moneys held for payment in trust, to register the transfer or exchange of such senior debt securities, to deliver such senior debt securities for replacement or to be canceled, to compensate and indemnify the trustee and to appoint a successor trustee, and our right to recover unclaimed money held by the trustee) shall survive until such senior debt securities are no longer outstanding. Thereafter, only our obligations to compensate and indemnify the trustee and our right to recover unclaimed money held by the trustee shall survive.

10

Modification and Waiver

We and the trustee may amend or supplement the senior indenture or the senior debt securities without the consent of any holder:

Other amendments and modifications of the senior indenture or the senior debt securities issued may be made, and our compliance with any provision of the senior indenture with respect to any series of senior debt securities may be waived, with the consent of the holders of not less than a majority of the aggregate principal amount of the outstanding senior debt securities of all series affected by the amendment or modification (voting as one class); provided, however, that each affected holder must consent to any modification, amendment or waiver that:

11

It shall not be necessary for the consent of the holders under this section of the senior indenture to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this section of the senior indenture becomes effective, the trustee must give to the holders affected thereby certain notice briefly describing the amendment, supplement or waiver. We will mail supplemental indentures to holders upon request. Any failure by the trustee to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture or waiver.

No Personal Liability of Incorporators, Stockholders, Officers or Directors

The senior indenture provides that no recourse shall be had under or upon any obligation, covenant, or agreement of ours in the senior indenture or any supplemental indenture, or in any of the senior debt securities or because of the creation of any indebtedness represented thereby, against any incorporator, stockholder, officer or director of ours or of any successor person thereof under any law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise. Each holder, by accepting the senior debt securities, waives and releases all such liability.

Concerning the Trustee

The senior indenture provides that, except during the continuance of a default, the trustee will not be liable, except for the performance of such duties as are specifically set forth in the senior indenture. If an event of default has occurred and is continuing, the trustee will exercise such rights and powers vested in it under the senior indenture and will use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

We and our affiliates may have normal banking relationships with the trustee under the senior indenture in the ordinary course of business.

Unclaimed Funds

All funds deposited with the trustee or any paying agent for the payment of principal, interest, premium or additional amounts in respect of the senior debt securities that remain unclaimed for two years after the maturity date of such senior debt securities will be repaid to us upon our request. Thereafter, any right of any noteholder to such funds shall be enforceable only against us, and the trustee and paying agents will have no liability therefor.

Governing Law

The senior indenture is, and the debt securities will be, governed by, and construed in accordance with, the internal laws of the State of New York.

12

Certain Terms of the Subordinated Debt Securities

Other than the terms of the subordinated indenture and subordinated debt securities relating to subordination, or otherwise as described in the prospectus supplement relating to a particular series of subordinated debt securities, the terms of the subordinated indenture and subordinated debt securities are identical in all material respects to the terms of the senior indenture and senior debt securities. Additional or different subordination terms may be specified in the prospectus supplement applicable to a particular series.

Subordination

The indebtedness evidenced by the subordinated debt securities is subordinate to the prior payment in full of all our Senior Indebtedness, as defined in the subordinated indenture. During the continuance beyond any applicable grace period of any default in the payment of principal, premium, interest or any other payment due on any of our Senior Indebtedness, we may not make any payment of principal of, or premium, if any, or interest on the subordinated debt securities. In addition, upon any payment or distribution of our assets upon any dissolution, winding up, liquidation or reorganization, the payment of the principal of, or premium, if any, and interest on the subordinated debt securities will be subordinated to the extent provided in the subordinated indenture in right of payment to the prior payment in full of all our Senior Indebtedness. Because of this subordination, if we dissolve or otherwise liquidate, holders of our subordinated debt securities may receive less, ratably, than holders of our Senior Indebtedness. The subordination provisions do not prevent the occurrence of an event of default under the subordinated indenture.

The term “Senior Indebtedness” of a person means with respect to such person the principal of, premium, if any, interest on, and any other payment due pursuant to any of the following, whether outstanding on the date of the subordinated indenture or incurred by that person in the future:

unless, in the case of any particular indebtedness, lease, renewal, extension or refunding, the instrument or lease creating or evidencing it or the assumption or guarantee relating to it expressly provides that such indebtedness, lease, renewal, extension or refunding is not superior in right of payment to the subordinated debt securities. Our senior debt securities constitute Senior Indebtedness for purposes of the subordinated debt indenture.

13

DESCRIPTION OF GUARANTEES OF OUR DEBT SECURITIES

Each prospectus supplement will describe any guarantees of debt securities for the benefit of the series of debt securities to which it relates. If so provided in a prospectus supplement, the debt securities will be guaranteed, jointly and severally, by each of the guarantors named in such prospectus supplement on a senior unsecured basis. The obligations of a guarantor under its guarantee will be limited to the extent necessary to prevent the obligations of such guarantor from constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

14

DESCRIPTION OF OUR CAPITAL STOCK

Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.01 per share, and 25,000,000 shares of preferred stock, par value $0.01 per share. Of the 200,000,000 shares of common stock authorized, 35,434,433 were outstanding as of September 30, 2022, 51,735,764 shares were held in treasury and 1,454,000 shares have been reserved for issuance under our incentive plans and employee stock purchase program. None of the preferred stock was outstanding as of September 30, 2022.

Common Stock

The holders of our common stock are entitled to one vote per share on all matters to be voted on by stockholders. Generally, all matters to be voted on by stockholders must be approved by a majority (or, in the case of a contested election of directors, by a plurality) of the votes entitled to be cast by all shares of common stock present in person or represented by proxy, voting together as a single class, except as may be required by law and subject to any voting rights granted to holders of any preferred stock. However, the removal of a director from office, the approval and authorization of specified business combinations and amendments to specified provisions of our certificate of incorporation each require the approval of not less than 80% of the combined voting power of our outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class. See “—Certificate of Incorporation and Bylaw Provisions.” The common stock does not have cumulative voting rights.

Subject to the prior rights of the holders of any shares of our preferred stock, the holders of our common stock shall be entitled to receive, to the extent permitted by law, such dividends as may be declared from time to time by our board of directors. On our liquidation, dissolution or winding up, after payment in full of the amounts required to be paid to holders of preferred stock, if any, all holders of common stock are entitled to share ratably in any assets available for distribution to holders of shares of common stock.

The outstanding shares of our common stock are legally issued, fully paid and nonassessable. The common stock does not have any preemptive, subscription or conversion rights. Additional shares of authorized common stock may be issued, as authorized by our board of directors from time to time, without stockholder approval, except as may be required by applicable stock exchange requirements.

Preferred Stock

Our board of directors may authorize the issuance of preferred stock in one or more series and may determine, for the series, the designations, powers, preferences and rights of such series, and the qualifications, limitations and restrictions of the series, including:

15

Although our board of directors has no intention at the present time of doing so, it could issue a series of preferred stock that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt. Our board of directors will make any determination to issue such shares based on its judgment as to our best interests and the best interests of our stockholders. Our board of directors, in so acting, could issue preferred stock having terms that could discourage a potential acquiror from making, without first negotiating with our board of directors, an acquisition attempt through which such acquiror may be able to change the composition of our board of directors, including a tender offer or other transaction that some, or a majority, of our stockholders might believe to be in their best interests or in which stockholders might receive a premium for their stock over the then current market price of such stock.

Business Combination Statute

As a corporation organized under the laws of the State of Delaware, we are subject to Section 203 of the Delaware General Corporation Law (the “DGCL”), which restricts specified business combinations between us and an “interested stockholder” or its affiliates or associates for a period of three years following the time that the stockholder becomes an “interested stockholder.” In general, an “interested stockholder” is defined as a stockholder owning 15% or more of our outstanding voting stock. The restrictions do not apply if:

Under some circumstances, Section 203 makes it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period, although the stockholders may elect to exclude a corporation from the restrictions imposed under Section 203. Our certificate of incorporation does not exclude us from the restrictions imposed under Section 203.

Certificate of Incorporation and Bylaw Provisions

The summary below describes provisions of our certificate of incorporation and bylaws. The provisions of our certificate of incorporation and bylaws discussed below may have the effect, either alone or in combination with the provisions of Section 203 of the DGCL discussed above, of making more difficult or discouraging a tender offer, proxy contest or other takeover attempt that is opposed by our board of directors but that a stockholder might consider to be in such stockholder’s best interest. Those provisions include:

16

Classified Board of Directors; Removal; Number of Directors; Filling Vacancies

Our certificate of incorporation and bylaws provide that our board of directors shall be divided into three classes, designated Class I, Class II and Class III, with the classes to be as nearly equal in number as possible. The term of office of each class shall expire at the third annual meeting of stockholders for the election of directors following the election of such class. Each director is to hold office until his or her successor is duly elected and qualified, or until his or her earlier resignation or removal.

Our bylaws provide that the number of directors will be fixed from time to time by a resolution adopted by our board of directors; provided that the number so fixed shall not be more than 15 nor less than three directors. Our bylaws also provide that any vacancies will be filled only by the affirmative vote of a majority of the remaining directors, even if less than a quorum. Accordingly, absent an amendment to the bylaws, our board of directors could prevent any stockholder from enlarging our board of directors and filling the new directorships with such stockholder’s own nominees. Moreover, our certificate of incorporation and bylaws provide that directors may be removed only for cause and only upon the affirmative vote of holders of at least 80% of our voting stock at a special meeting of stockholders called expressly for that purpose.

The classification of directors could have the effect of making it more difficult for stockholders to change the composition of our board of directors. At least two annual meetings of stockholders, instead of one, are generally required to effect a change in a majority of our board of directors. Such a delay may help ensure that our directors, if confronted by a holder attempting to force a proxy contest, a tender or exchange offer, or an extraordinary corporate transaction, would have sufficient time to review the proposal as well as any available alternatives to the proposal and to act in what they believe to be the best interest of the stockholders. The classification provisions will apply to every election of directors, however, regardless of whether a change in the composition of our board of directors would be beneficial to us and our stockholders and whether or not a majority of our stockholders believe that such a change would be desirable.

The classification provisions could also have the effect of discouraging a third party from initiating a proxy contest, making a tender offer or otherwise attempting to obtain control of us, even though such an attempt might be beneficial to us and our stockholders. The classification of our board of directors could thus increase the likelihood that incumbent directors will retain their positions. In addition, because the classification provisions may discourage accumulations of large blocks of our stock by purchasers whose objective is to take control of us and remove a majority of our board of directors, the classification of our board of directors could tend to reduce the likelihood of fluctuations in the market price of the common stock that might result from accumulations of large blocks. Accordingly, stockholders could be deprived of opportunities to sell their shares of common stock at a higher market price than might otherwise be the case.

No Stockholder Action by Written Consent; Special Meetings

Our certificate of incorporation and bylaws provide that stockholder action can be taken only at an annual or special meeting of stockholders and stockholder action may not be taken by written consent in lieu of a meeting. Special meetings of stockholders can be called only by our board of directors by a resolution adopted by a majority of our board of directors, or by the chairman of the board, vice chairman or the president. Moreover, the business permitted to be conducted at any special meeting of stockholders is limited to the business brought before the meeting under the notice of meeting given by us.

17

The provisions of our certificate of incorporation and bylaws prohibiting stockholder action by written consent and permitting special meetings to be called only by the chairman, vice chairman or president, or at the request of a majority of our board or directors, may have the effect of delaying consideration of a stockholder proposal until the next annual meeting. The provisions would also prevent the holders of a majority of our voting stock from unilaterally using the written consent procedure to take stockholder action. Moreover, a stockholder could not force stockholder consideration of a proposal over the opposition of the chairman, vice chairman or president, or a majority of our board of directors, by calling a special meeting of stockholders prior to the time such parties believe such consideration to be appropriate.

Advance Notice Provisions for Stockholder Nominations and Stockholder Proposals

Our bylaws establish an advance notice procedure for stockholders to make nominations of candidates for election as directors or bring other business before an annual meeting of stockholders.

The stockholder notice procedure provides that only persons who are nominated by, or at the direction of, our board of directors, or by a stockholder who has given timely written notice containing specified information to our secretary prior to the meeting at which directors are to be elected, will be eligible for election as our directors. The stockholder notice procedure also provides that at an annual meeting only such business may be conducted as has been brought before the meeting by, or at the direction of, the chairman of the board of directors, or in the absence of the chairman of the board, the president, or by a stockholder who has given timely written notice containing specified information to our secretary of such stockholder’s intention to bring such business before such meeting. Under the stockholder notice procedure, for notice of stockholder nominations or proposals to be made at an annual meeting to be timely, such notice must be received by us not less than 60 days nor more than 90 days in advance of such meeting. For notice of stockholder nominations or proposals to be made at a special meeting of stockholders to be timely, such notice must be received by us not later than the close of business on the tenth day following the date on which notice of such meeting is first given to stockholders. However, in the event that less than 70 days’ notice or prior public disclosure of the date of the meeting of stockholders is given or made to the stockholders, to be timely, notice of a nomination or proposal delivered by the stockholder must be received by our secretary not later than the close of business on the tenth day following the day on which notice of the date of the meeting of stockholders was mailed or such public disclosure was made to the stockholders. If our board of directors or, alternatively, the presiding officer at a meeting, in the case of a stockholder proposal, or the chairman of the meeting, in the case of a stockholder nomination to our board of directors, determines at or prior to the meeting that business was not brought before the meeting or a person was not nominated in accordance with the stockholder notice procedure, such business will not be conducted at such meeting, or such person will not be eligible for election as a director, as the case may be.

By requiring advance notice of nominations by stockholders, the stockholder notice procedure will afford our board of directors an opportunity to consider the qualifications of the proposed nominees and, to the extent considered necessary or desirable by our board of directors, to inform stockholders about such qualifications. By requiring advance notice of other proposed business, the stockholder notice procedure will also provide a more orderly procedure for conducting annual meetings of stockholders and, to the extent considered necessary or desirable by our board of directors, will provide our board of directors with an opportunity to inform stockholders, prior to such meetings, of any business proposed to be conducted at such meetings, together with any recommendations as to our board of directors’ position regarding action to be taken regarding such business, so that stockholders can better decide whether to attend such a meeting or to grant a proxy regarding the disposition of any such business.

Although our bylaws do not give our board of directors any power to approve or disapprove stockholder nominations for the election of directors or proposals for action, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if the proper procedures are not followed, and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal, without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our stockholders.

18

Fair Price Provision

Our certificate of incorporation contains a “fair price” provision that applies to specified business combination transactions involving any person, entity or group that beneficially owns at least 10% of our aggregate voting stock—such person, entity or group is sometimes referred to as a “related person.” This provision requires the affirmative vote of the holders of not less than 80% of our voting stock to approve specified transactions between a related person and us or our subsidiaries, including:

This voting requirement will not apply to certain transactions, including:

This provision could have the effect of delaying or preventing a change in control of us in a transaction or series of transactions that did not satisfy the “fair price” criteria.

Liability of Directors; Indemnification

Our certificate of incorporation provides that a director will not be personally liable for monetary damages to us or our stockholders for breach of fiduciary duty as a director, except for liability:

19

Any amendment or repeal of such provision shall not adversely affect any right or protection of a director existing under such provision for any act or omission occurring prior to such amendment or repeal.

Our bylaws provide that each person who at any time serves or served as one of our directors or officers, or any person who, while one of our directors or officers, is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, shall be entitled to indemnification and the advancement of expenses from us, and to the fullest extent, permitted by Section 145 of the DGCL or any successor statutory provision. We will indemnify any person who was or is a party to any threatened, pending or completed action, suit or proceeding because he or she is or was one of our directors or officers, or is or was serving at our request as a director or officer of another corporation, partnership or other enterprise. However, as provided in Section 145, this indemnification will only be provided if the indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests.

Amendments

Our certificate of incorporation provides that we reserve the right to amend, alter, change, or repeal any provision contained in our certificate of incorporation, and all rights conferred to stockholders are granted subject to such reservation. The affirmative vote of holders of not less than 80% of our voting stock, voting together as a single class, shall be required to alter, amend, adopt any provision inconsistent with or repeal specified provisions of our certificate of incorporation, including those provisions discussed in this section. In addition, the 80% vote described in the prior sentence shall not be required for any alteration, amendment, adoption of inconsistent provision or repeal of the “fair price” provision discussed under “—Fair Price Provision” above which is recommended to the stockholders by two-thirds of our continuing directors and such alteration, amendment, adoption of inconsistent provision or repeal shall require the vote, if any, required under the applicable provisions of the DGCL and our certificate of incorporation. In addition, our certificate of incorporation provides that stockholders may only adopt, amend or repeal our bylaws by the affirmative vote of holders of not less than 80% of our voting stock, voting together as a single class. Our bylaws may be amended by our board of directors.

Rights To Purchase Securities And Other Property

Our certificate of incorporation authorizes our board of directors to create and issue rights, warrants and options entitling the holders of them to purchase from us shares of any class or classes of our capital stock or other securities or property upon such terms and conditions as our board of directors may deem advisable.

Listing

Our common stock is listed on the New York Stock Exchange under the symbol “LII.”

Transfer Agent And Registrar

The transfer agent and registrar for the common stock is Computershare Trust Company, N.A.

20

DESCRIPTION OF OUR WARRANTS

We may issue warrants to purchase any combination of debt securities, common stock, preferred stock, rights or other securities of Lennox or any other entity. Warrants may be issued independently or together with other securities and may be attached to or separate from other securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not have any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. A copy of the warrant agreement will be filed with the SEC in connection with any offering of warrants.

The prospectus supplement relating to a particular issue of warrants to issue debt securities, preferred stock or common stock will describe the terms of those warrants, including the following:

21

DESCRIPTION OF OUR DEPOSITARY SHARES

General

At our option, we may elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. If we do elect to offer fractional shares of preferred stock, we will issue to the public receipts for depositary shares and each of these depositary shares will represent a fraction of a share of a particular series of preferred stock, as specified in the applicable prospectus supplement. Each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in shares of preferred stock underlying that depositary share, to all rights and preferences of the preferred stock underlying that depositary share. These rights may include dividend, voting, redemption and liquidation rights.

The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary, under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

The summary of terms of the depositary shares contained in this prospectus is not complete. You should refer to the forms of the deposit agreement, our certificate of incorporation and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends

The depositary will distribute cash dividends or other cash distributions, if any, received in respect of the series of preferred stock underlying the depositary shares to the record holders of depositary receipts in proportion to the number of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the preferred stock. In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts that are entitled to receive the distribution, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary, with our approval, may adopt another method for the distribution, including selling the property and distributing the net proceeds to the holders.

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of the voluntary or involuntary liquidation, dissolution or winding up of Lennox, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Redemption

If a series of preferred stock underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the preferred stock held by the depositary. Whenever we redeem any preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing the preferred stock so redeemed. The depositary will mail the notice of redemption to the record holders of the depositary receipts promptly upon receiving the notice from, unless otherwise provided in the applicable prospectus supplement, prior to the date fixed for redemption of the preferred stock.

22

Voting

Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts underlying the preferred stock. Each record holder of those depositary receipts on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock underlying that holder’s depositary shares. The record date for the depositary will be the same date as the record date for the preferred stock. The depositary will try, as far as practicable, to vote the preferred stock underlying the depositary shares in accordance with these instructions. We will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to vote the preferred stock in accordance with these instructions. The depositary will not vote the preferred stock to the extent that it does not receive specific instructions from the holders of depositary receipts.

Withdrawal of Preferred Stock

Owners of depositary shares will be entitled to receive upon surrender of depositary receipts at the principal office of the depositary and payment of any unpaid amount due to the depositary, the number of whole shares of preferred stock underlying their depositary shares. Partial shares of preferred stock will not be issued. Holders of preferred stock will not be entitled to deposit the shares under the deposit agreement or to receive depositary receipts evidencing depositary shares for the preferred stock.

Amendment and Termination of Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. However, any amendment which materially and adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by at least a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangement. We will also pay charges of the depositary in connection with:

Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and other specified charges as provided in the deposit agreement for their accounts. If these charges have not been paid, the depositary may:

23

Miscellaneous

The depositary will forward to the holders of depositary receipts all reports and communications we deliver to the depositary that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock. Neither the depositary nor Lennox will be liable if either the depositary or Lennox is prevented or delayed by law or any circumstance beyond either the depositary or Lennox’s control in performing their respective obligations under the deposit agreement. Our obligations and the depositary’s obligations will be limited to the performance in good faith of our or the depositary’s respective duties under the deposit agreement. Neither the depositary nor Lennox will be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished.

We and the depositary may rely on:

Resignation and Removal of Depositary

The depositary may resign at any time by delivering a notice to us. We may remove the depositary at any time. Any such resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice for resignation or removal. The successor depositary must be a bank and trust company having its principal office in the United States of America and having a combined capital and surplus of at least $150,000,000.

Certain Federal Income Tax Consequences

Owners of the depositary shares will be treated for federal income tax purposes as if they were owners of the preferred stock underlying the depositary shares. As a result, owners will be entitled to take into account for federal income tax purposes and deductions to which they would be entitled if they were holders of such preferred stock. No gain or loss will be recognized for federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares. The tax basis of each share of preferred stock to an exchanging owner of depositary shares will, upon such exchange, be the same as the aggregate tax basis of the depositary shares exchanged. The holding period for preferred stock in the hands of an exchanging owner of depositary shares will include the period during which such person owned such depositary shares.

24

DESCRIPTION OF OUR UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more warrants, debt securities, shares of preferred stock, shares of common stock or any combination of such securities. The applicable prospectus supplement will describe:

25

PLAN OF DISTRIBUTION

We may sell the offered securities in and outside the United States (1) through underwriters or dealers, (2) directly to purchasers, including our affiliates, (3) through agents or (4) through a combination of any of these methods. The prospectus supplement will include the following information:

Sale through Underwriters or Dealers

If we use underwriters in the sale, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

If we use dealers in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at varying prices determined by the dealers at the time of resale. The dealers participating in any sale of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended (the “Securities Act”) with respect to any sale of those securities. We will include in the prospectus supplement the names of the dealers and the terms of the transaction.

Direct Sales and Sales Through Agents

We may sell the securities directly. In that event, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. In the prospectus supplement, we will name

26

any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable by us to the agent. Unless we inform you otherwise in the prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any such sales in the prospectus supplement.

Delayed Delivery Contracts

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

Remarketing

We may offer and sell any of the offered securities in connection with a remarketing upon their purchase, in accordance with a redemption or repayment by their terms or otherwise by one or more remarketing firms acting as principals for their own accounts or as our agents. We will identify any remarketing firm, the terms of any remarketing agreement and the compensation to be paid to the remarketing firm in the prospectus supplement. Remarketing firms may be deemed underwriters under the Securities Act.

Derivative Transactions

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third parties may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third parties in these sale transactions will be underwriters and, if not identified in this prospectus, will be identified in the applicable prospectus supplement or in a post-effective amendment to the registration statement of which this prospectus is a part.

General Information

We may have agreements with the remarketing firms, agents, dealers and underwriters to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the agents, dealers or underwriters may be required to make. Such firms, agents, dealers and underwriters may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

Each series of offered securities will be a new issue, and other than the common stock, which is listed on the New York Stock Exchange, will have no established trading market. We may elect to list any series of offered securities on an exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a series of offered securities. However, they will not be obligated to do so and may discontinue market making at any time without notice. We cannot assure you that a liquid trading market for any of our offered securities will develop.

27

LEGAL MATTERS

Unless the applicable prospectus supplement indicates otherwise, the validity of the securities described in this prospectus will be passed upon for us by Jones Day, Dallas, Texas. Additional legal matters may be passed upon for us, or any underwriters, dealers or agents, by counsel named in the applicable prospectus supplement.

ITEM 14. Other Expenses of Issuance and Distribution

The following table sets forth expenses payable by Lennox in connection with the issuance and distribution of the securities being registered, other than underwriting fees and commissions. All of the amounts shown are estimates.

ITEM 15. Indemnification of Directors and Officers

California

California Corporations Code

Section 317 of the California Corporations Code (the “CCC”) authorizes a corporation to indemnify a person who is a party or is threatened to be made a party to any suit (other than a suit by or in the right of the corporation) by reason of the fact that such person is or was the corporation’s director or officer, or is or was serving at the corporation’s request as a director or officer of another entity, for expenses (including attorneys’ fees) and other liabilities actually and reasonably incurred by such person in connection with any such suit, provided such person acted in good faith and in a manner reasonably believed to be in the best interests of the corporation and, with respect to criminal actions, had no reasonable cause to believe his or her conduct was unlawful. Section 317 provides further that a corporation may indemnify a director or officer for expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of a suit by or in the right of the corporation, provided such person acted in good faith and in a manner reasonably believed to be in the best interests of the corporation and its shareholders. To the extent a corporation’s director or officer is successful on the merits in the defense of any such suit, that person shall be indemnified against expenses actually and reasonably incurred. Under Section 317 of the CCC, expenses incurred in defending any suit may be advanced by the corporation prior to the final disposition of the proceeding upon receipt of any undertaking by or on behalf of the director or officer to repay that amount if it is ultimately determined that he or she is not entitled to indemnification.

Lennox National Account Services Inc.

The bylaws of Lennox National Account Services Inc. (“LNAS Inc.”) provide that LNAS Inc. may indemnify each of its agents against expenses, judgments, fines, settlements and other amounts, actually and reasonably incurred by such person having been made or having been threatened to be made a party to a

II-1

proceeding to the fullest extent permissible under the provisions of Section 317 of the CCC. LNAS Inc. also may, in its sole discretion, advance the expenses reasonably expected to be incurred by such agent in defending any such proceeding upon receipt of the undertaking required by Section 317(f) of the CCC.

Delaware

Delaware General Corporation Law

Section 145 of the DGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, if the person had no reasonable cause to believe the person’s conduct was unlawful.

Section 145 further provides that a corporation similarly may indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of the action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.

Lennox International Inc.

Article Eighth of the Restated Certificate of Incorporation of Lennox International Inc. (the “Company”) provides that a director of the Company shall not be liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended. Any repeal or modification of Article Eighth shall not adversely affect any right or protection of a director of the Company existing thereunder with respect to any act or omission occurring prior to such repeal or modification.

Article VI of the Amended and Restated Bylaws (the “Bylaws”) of the Company provides that each person who at any time shall serve or shall have served as a director or officer of the Company, or any person who, while a director or officer of the Company, is or was serving at the request of the Company as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, shall be entitled to (a) indemnification and (b) the advancement of expenses incurred by such person from the Company as, and to the fullest extent, permitted by Section 145 of the DGCL or any successor statutory provision, as from time to time amended. The Company may indemnify any other person, to the same extent and subject to the same limitations specified in the immediately preceding sentence, by reason of the fact that such other person is or was an employee or agent of the Company or another corporation, partnership, joint venture, trust or other enterprise.

The indemnification and advancement of expenses provided by, or granted pursuant to, Article VI shall not be deemed exclusive of any other rights to which any person seeking indemnification or advancement of expenses may be entitled under any agreement, vote of stockholders or disinterested directors or otherwise, both

II-2

as to action in such person’s official capacity and as to action in another capacity while holding such office. All rights to indemnification under Article VI shall be deemed to be provided by a contract between the Company and the director, officer, employee or agent who served in such capacity at any time while the Bylaws and other relevant provisions of the DGCL and other applicable law, if any, are in effect.

ITEM 16. Exhibits

II-7

ITEM 17. Undertakings

(a) Each of the undersigned registrants hereby undertakes:

II-8

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement.

II-9

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(d) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under Section 305(b)(2) of the Trust Indenture Act.

Lennox International Inc.

Richardson, Texas 75080

Ladies and Gentlemen:

We have acted as counsel for Lennox International Inc., a Delaware corporation (“Lennox”), and the guarantors listed on Annex A hereto (the “Guarantors”), in connection with the authorization of the issuance and sale from time to time, on a delayed basis, by Lennox and the Guarantors, as applicable, of an indeterminate amount of: (1) shares of common stock, par value $0.01 per share, of Lennox (the “Common Stock”); (2) shares of preferred stock, par value $0.01 per share, of Lennox (the “Preferred Stock”), in one or more series, certain of which may be convertible into or exchangeable for Common Stock; (3) depositary shares of Lennox representing fractional interests in Preferred Stock (the “Depositary Shares”); (4) senior debt securities of Lennox (the “Senior Debt Securities”) and subordinated debt securities of Lennox (the “Subordinated Debt Securities” and, together with the Senior Debt Securities, the “Debt Securities”), in one or more series, certain of which Debt Securities may be convertible into or exchangeable for Common Stock or other securities of Lennox or any other person; (5) guarantees of Lennox’s obligations under the Debt Securities by the Guarantors (the “Guarantees”); (6) warrants to purchase Common Stock, Preferred Stock, Debt Securities, rights or other securities of Lennox or any other entity (the “Warrants”); and (7) units consisting of Common Stock, Preferred Stock, Debt Securities or Warrants or any combination of such securities (the “Units”), in each case as contemplated by the Registration Statement of Lennox and the Guarantors on Form S-3 to which this opinion is filed as an exhibit (as the same may be amended from time to time, the “Registration Statement”). The Common Stock, the Preferred Stock, the Depositary Shares, the Debt Securities, the Guarantees, the Warrants, and the Units are collectively referred to herein as the “Securities” and each, a “Security.” The Securities may be offered and sold from time to time pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). The Senior Debt Securities and related Guarantees are to be issued under an Indenture, dated as of May 3, 2010 (as the same may be supplemented from time to time, the “Indenture”), between Lennox, as issuer, and U.S. Bank Trust Company, National Association (successor in interest to U.S. Bank National Association), as trustee (the “Senior Debt Trustee”).

In connection with the opinions expressed herein, we have examined such documents, records and matters of law as we have deemed relevant or necessary for purposes of these opinions. Based on the foregoing, and subject to the further limitations, qualifications and assumptions set forth herein, we are of the opinion that:

October 27, 2022

Page 2

1. The shares of Common Stock, upon receipt by Lennox of such lawful consideration therefor having a value not less than the par value thereof as the Lennox Board of Directors (or an authorized committee thereof) may determine, will be validly issued, fully paid and nonassessable.

2. The shares of Preferred Stock, upon receipt by Lennox of such lawful consideration therefor having a value not less than the par value thereof as the Lennox Board of Directors (or an authorized committee thereof) may determine, will be validly issued, fully paid and nonassessable.

3. The Depositary Shares, upon receipt by Lennox of such lawful consideration therefor as the Lennox Board of Directors (or an authorized committee thereof) may determine, will be validly issued, and the depositary receipts representing the Depositary Shares will entitle the holders thereof to the rights specified therein and in the deposit agreement pursuant to which they are issued.

4. The Debt Securities, upon receipt by Lennox of such lawful consideration therefor as the Lennox Board of Directors (or a duly authorized committee thereof) may determine, will constitute valid and binding obligations of Lennox.

5. Upon the execution, authentication, issuance, sale and delivery of the Debt Securities as described above, the Guarantees, as applicable, will constitute valid and binding obligations of Lennox.

6. The Warrants, upon receipt by Lennox of such lawful consideration therefor as the Lennox Board of Directors (or an authorized committee thereof) may determine, will constitute valid and binding obligations of Lennox.

7. The Units, upon receipt by Lennox of such lawful consideration therefor as the Lennox Board of Directors (or an authorized committee thereof) may determine, will constitute valid and binding obligations of Lennox.

In rendering the foregoing opinions, we have assumed that: (i) the Registration Statement, and any amendments thereto, will have become effective (and will remain effective at the time of issuance of any Securities thereunder); (ii) a prospectus supplement describing each class and/or series of Securities offered pursuant to the Registration Statement, to the extent required by applicable law and relevant rules and regulations of the Securities and Exchange

October 27, 2022

Page 3

Commission (the “Commission”), will be timely filed with the Commission; (iii) the definitive terms of each class and/or series of Securities will have been established in accordance with the authorizing resolutions adopted by the Board of Directors of Lennox and the Guarantors (or an authorized committee thereof) or other governing body of the Guarantors, as applicable, and, as applicable, Lennox’s and the Guarantors’ certificate of incorporation, certificate of formation or other governing documents, as applicable, and applicable law; (iv) Lennox and the Guarantors, as applicable, will issue and deliver the applicable Securities in the manner contemplated by the Registration Statement and any Securities that consist of shares of capital stock will have been authorized and reserved for issuance, in each case within the limits of the then-remaining authorized but unissued and unreserved amounts of such capital stock; (v) the resolutions authorizing Lennox and the Guarantors, as applicable, to issue, offer and sell the Securities will have been adopted by the Board of Directors of Lennox and the Guarantors (or an authorized committee thereof) or other governing body of the Guarantors, as applicable, and will be in full force and effect at all times at which the Securities are offered or sold by Lennox and/or the Guarantors, as applicable; (vi) all Securities will be issued in compliance with applicable federal and state securities laws; and (vii) any Subordinated Indenture, Deposit Agreement, Warrant Agreement (each as defined below) or unit agreement will be governed by and construed in accordance with the laws of the State of New York and will constitute a valid and binding obligation of each party thereto other than Lennox and the Guarantors, as applicable.

With respect to any Securities consisting of Preferred Stock, we have further assumed that Lennox will issue and deliver the shares of Preferred Stock being issued and delivered after the filing with the Secretary of State of the State of Delaware of a certificate of amendment to the Lennox certificate of incorporation, approved by us, establishing the designations, preferences and rights of the class or series of Preferred Stock being issued and delivered.

With respect to any Securities consisting of Depositary Shares, we have further assumed that the Depositary Shares will be: (i) issued and delivered after authorization, execution and delivery of the deposit agreement, approved by us, relating to the Depositary Shares to be entered into between Lennox and an entity (the “Depositary”) selected by Lennox to act as depositary (the “Deposit Agreement”) and (ii) issued after Lennox deposits with the Depositary shares of the Preferred Stock to be represented by such Depositary Shares that are authorized, validly issued, fully paid and nonassessable as contemplated by the Registration Statement and the Deposit Agreement.

With respect to any Securities consisting of any series of Senior Debt Securities and the Guarantees, we have further assumed that (i) the Senior Debt Securities and related Guarantees will have been issued pursuant to the Indenture and that the Indenture is, and any supplemental indenture will be, a valid and binding obligation of the Senior Debt Trustee; (ii) all terms of the Senior Debt Securities or Guarantees not provided for in the Indenture will have been established

October 27, 2022

Page 4

in accordance with the provisions of the Indenture and reflected in appropriate documentation approved by us and, if applicable, duly executed and delivered by Lennox, the Guarantors and the Senior Debt Trustee; and (iii) the Senior Debt Securities and related Guarantees will be duly executed, authenticated, issued and delivered in accordance with the provisions of the Indenture.

With respect to any Securities consisting of any series of Subordinated Debt Securities and the Guarantees, we have further assumed that (i) the Subordinated Debt Securities and related Guarantees will have been issued pursuant to an indenture (the “Subordinated Indenture”), in a form approved by us, that has been authorized, executed and delivered by Lennox, the Guarantors and one or more entities selected by Lennox to act as trustee (the “Subordinated Debt Trustee”), and the Subordinated Indenture will have been qualified under the Trust Indenture Act of 1939; (ii) all terms of the Subordinated Debt Securities or Guarantees not provided for in the Subordinated Indenture will have been established in accordance with the provisions of the Subordinated Indenture and reflected in appropriate documentation approved by us and, if applicable, duly executed and delivered by Lennox, the Guarantors and the Subordinated Debt Trustee; and (iii) the Subordinated Debt Securities and related Guarantees will be duly executed, authenticated, issued and delivered in accordance with the provisions of the Subordinated Indenture.

With respect to any Securities consisting of Warrants, we have further assumed that (i) the warrant agreement, approved by us, relating to the Warrants (the “Warrant Agreement”) to be entered into between Lennox and an entity selected by Lennox to act as the warrant agent (the “Warrant Agent”) will have been authorized, executed and delivered by Lennox and the Warrant Agent and (ii) the Warrants will be authorized, executed and delivered by Lennox and the Warrant Agent in accordance with the provisions of the Warrant Agreement.

With respect to any Securities consisting of Units, we have further assumed that each component of such Unit will be authorized, validly issued, fully paid and nonassessable (to the extent applicable) and will constitute a valid and binding obligation of Lennox or any third party (to the extent applicable) as contemplated by the Registration Statement and the applicable unit agreement, if any.

The opinions set forth in paragraphs 3, 4, 5, 6 and 7 are limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer and fraudulent conveyance, voidable preference, moratorium or other similar laws and related regulations and judicial doctrines from time to time in effect relating to or affecting creditors’ rights generally and (ii) general equitable principles and public policy considerations, whether such principles and considerations are considered in a proceeding at law or at equity.

October 27, 2022

Page 5

For purposes of our opinions insofar as they relate to the Guarantors, we have assumed that the obligations of each Guarantor under the Guarantees will be at the time of issuance of any Guarantees, and would be deemed by a court of competent jurisdiction to be, in furtherance of its corporate or other entity purposes, or necessary or convenient to the conduct, promotion or attainment of the business of the respective Guarantor and will benefit the respective Guarantor, directly or indirectly.

As to facts material to the opinions and assumptions expressed herein, we have relied upon oral or written statements and representations of officers and other representatives of Lennox, the Guarantors and others.

The opinions expressed herein are limited to (i) the laws of the State of New York, (ii) the laws of the State of Florida, (iii) the laws of the State of California, (iv) the Delaware General Corporation Law and (v) the Limited Liability Company Act of the State of Delaware, in each case as currently in effect, and we express no opinion as to the effect of the laws of any other jurisdiction.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the reference to Jones Day under the caption “Legal Matters” in the prospectus constituting a part of such Registration Statement. In giving such consent, we do not thereby admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission promulgated thereunder.

Exhibit 1

ARTICLES OF ASSOCIATION

OF

U. S. BANK TRUST COMPANY, NATIONAL ASSOCIATION

For the purpose of organizing an association (the “Association) to perform any lawful activities of national banks, the undersigned enter into the following Articles of Association:

FIRST. The title of this Association shall be U. S. Bank Trust Company, National Association.

SECOND. The main office of the Association shall be in the city of Portland, county of Multnomah, state of Oregon. The business of the Association will be limited to fiduciary powers and the support of activities incidental to the exercise of those powers. The Association may not expand or alter its business beyond that stated in this article without the prior approval of the Comptroller of the Currency.

THIRD. The board of directors of the Association shall consist of not less than five nor more than twenty-five persons, the exact number to be fixed and determined from time to time by resolution of a majority of the full board of directors or by resolution of a majority of the shareholders at any annual or special meeting thereof. Each director shall own common or preferred stock of the Association or of a holding company owning the Association, with an aggregate par, fair market, or equity value of not less than $1,000, as of either (i) the date of purchase, (ii) the date the person became a director, or (iii) the date of that person’s most recent election to the board of directors, whichever is more recent. Any combination of common or preferred stock of the Association or holding company may be used.

Any vacancy in the board of directors may be filled by action of a majority of the remaining directors between meetings of shareholders. The board of directors may increase the number of directors up to the maximum permitted by law. Terms of directors, including directors selected to fill vacancies, shall expire at the next regular meeting of shareholders at which directors are elected, unless the directors resign or are removed from office. Despite the expiration of a director’s term, the director shall continue to serve until his or her successor is elected and qualified or until there is a decrease in the number of directors and his or her position is eliminated.

Honorary or advisory members of the board of directors, without voting power or power of final decision in matters concerning the business of the Association, may be appointed by resolution of a majority of the full board of directors, or by resolution of shareholders at any annual or special meeting. Honorary or advisory directors shall not be counted to determined the number of directors of the Association or the presence of a quorum in connection with any board action, and shall not be required to own qualifying shares.

- 1 -

FOURTH. There shall be an annual meeting of the shareholders to elect directors and transact whatever other business may be brought before the meeting. It shall be held at the main office or any other convenient place the board of directors may designate, on the day of each year specified therefor in the Bylaws, or if that day falls on a legal holiday in the state in which the Association is located, on the next following banking day. If no election is held on the day fixed or in the event of a legal holiday on the following banking day, an election may be held on any subsequent day within 60 days of the day fixed, to be designated by the board of directors, or, if the directors fail to fix the day, by shareholders representing two-thirds of the shares issued and outstanding. In all cases, at least 10 days’ advance notice of the meeting shall be given to the shareholders by first-class mail.

In all elections of directors, the number of votes each common shareholder may cast will be determined by multiplying the number of shares he or she owns by the number of directors to be elected. Those votes may be cumulated and cast for a single candidate or may be distributed among two or more candidates in the manner selected by the shareholder. On all other questions, each common shareholder shall be entitled to one vote for each share of stock held by him or her.

A director may resign at any time by delivering written notice to the board of directors, its chairperson, or to the Association, which resignation shall be effective when the notice is delivered unless the notice specifies a later effective date.

A director may be removed by the shareholders at a meeting called to remove him or her, when notice of the meeting stating that the purpose or one of the purposes is to remove him or her is provided, if there is a failure to fulfill one of the affirmative requirements for qualification, or for cause; provided, however, that a director may not be removed if the number of votes sufficient to elect him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of the Association shall be 1,000,000 shares of common stock of the par value of ten dollars ($10) each; but said capital stock may be increased or decreased from time to time, according to the provisions of the laws of the United States. The Association shall have only one class of capital stock.

No holder of shares of the capital stock of any class of the Association shall have any preemptive or preferential right of subscription to any shares of any class of stock of the Association, whether now or hereafter authorized, or to any obligations convertible into stock of the Association, issued, or sold, nor any right of subscription to any thereof other than such, if any, as the board of directors, in its discretion, may from time to time determine and at such price as the board of directors may from time to time fix.

Transfers of the Association’s stock are subject to the prior written approval of a federal depository institution regulatory agency. If no other agency approval is required, the approval of the Comptroller of the Currency must be obtained prior to any such transfers.

Unless otherwise specified in the Articles of Association or required by law, (1) all matters requiring shareholder action, including amendments to the Articles of Association must be approved by shareholders owning a majority voting interest in the outstanding voting stock, and (2) each shareholder shall be entitled to one vote per share.

- 2 -

Unless otherwise specified in the Articles of Association or required by law, all shares of voting stock shall be voted together as a class, on any matters requiring shareholder approval.

Unless otherwise provided in the Bylaws, the record date for determining shareholders entitled to notice of and to vote at any meeting is the close of business on the day before the first notice is mailed or otherwise sent to the shareholders, provided that in no event may a record date be more than 70 days before the meeting.

The Association, at any time and from time to time, may authorize and issue debt obligations, whether subordinated, without the approval of the shareholders. Obligations classified as debt, whether subordinated, which may be issued by the Association without the approval of shareholders, do not carry voting rights on any issue, including an increase or decrease in the aggregate number of the securities, or the exchange or reclassification of all or part of securities into securities of another class or series.

SIXTH. The board of directors shall appoint one of its members president of this Association and one of its members chairperson of the board and shall have the power to appoint one or more vice presidents, a secretary who shall keep minutes of the directors’ and shareholders’ meetings and be responsible for authenticating the records of the Association, and such other officers and employees as may be required to transact the business of this Association. A duly appointed officer may appoint one or more officers or assistant officers if authorized by the board of directors in accordance with the Bylaws.

The board of directors shall have the power to:

SEVENTH. The board of directors shall have the power to change the location of the main office to any authorized branch within the limits of the city of Portland, Oregon, without the approval of the shareholders, or with a vote of shareholders owning two-thirds of the stock of the Association for a location outside such limits and upon receipt of a certificate of approval from the Comptroller of the Currency, to any other location within or outside the limits of the city of Portland, Oregon, but not more than thirty miles beyond such limits. The board of directors shall have the power to establish or change the location of any office or offices of the Association to any other location permitted under applicable law, without approval of shareholders, subject to approval by the Comptroller of the Currency.

EIGHTH. The corporate existence of this Association shall continue until termination according to the laws of the United States.

NINTH. The board of directors of the Association, or any shareholder owning, in the aggregate, not less than 25 percent of the stock of the Association, may call a special meeting of shareholders at any time. Unless otherwise provided by the Bylaws or the laws of the United States, or waived by shareholders, a notice of the time, place, and purpose of every annual and special meeting of the shareholders shall be given by first-class mail, postage prepaid, mailed at least 10, and no more than 60, days prior to the date of the meeting to each shareholder of record at his/her address as shown upon the books of the Association. Unless otherwise provided by the Bylaws, any action requiring approval of shareholders must be effected at a duly called annual or special meeting.

TENTH. These Articles of Association may be amended at any regular or special meeting of the shareholders by the affirmative vote of the holders of a majority of the stock of the Association, unless the vote of the holders of a greater amount of stock is required by law, and in that case by the vote of the holders of such greater amount; provided, that the scope of the Association’s activities and services may not be expanded without the prior written approval of the Comptroller of the Currency. The Association’s board of directors may propose one or more amendments to the Articles of Association for submission to the shareholders.
