CERTIFICATE OF INCORPORATION

OF

GOODMAN GLOBAL, INC.

Goodman Global, Inc. is a corporation organized and existing under the laws of the State of Delaware (the “Corporation”). The original Certificate of Incorporation of the Corporation (the “Certificate of Incorporation”) was filed with the Secretary of State of the State of Delaware on November 16, 2004 under the name Frio Holdings, Inc. A Certificate of Amendment to the Certificate of Incorporation of the Corporation (the “Certificate of Amendment to the Certificate of Incorporation”) was filed with the Secretary of State of the State of Delaware on November 30, 2004, which amended the Certificate of Incorporation to change the name of the Corporation from Frio Holdings, Inc. to Goodman Global, Inc. A second Certificate of Amendment to the Certificate of Incorporation of the Corporation (the “Second Certificate of Amendment to the Certificate of Incorporation”) was filed with the Secretary of State of the State of Delaware on December 17, 2004, which authorized the issuance of 7,250,000 shares, consisting of (i) 7,000,000 shares of common stock, $.01 par value per share, and 250,000 shares of preferred stock, $.01 par value per share. This Amended and Restated Certificate of Incorporation of the Corporation (the “Amended and Restated Certificate of Incorporation”), which restates, integrates and further amends the Certificate of Incorporation, the Certificate of Amendment to the Certificate of Incorporation and the Second Certificate of Amendment to the Certificate of Incorporation in their entirety, was duly adopted by the board of directors of the Corporation (the “Board of Directors”) and the stockholders of the Corporation in accordance with Sections 228, 242 and 245 of the General Corporation Law of the State of Delaware to read as follows:

FIRST: The name of the corporation is GOODMAN GLOBAL, INC. (the “Corporation”).

SECOND: The address of the Corporation’s registered office in the State of Delaware is 2711 Centerville Road, Suite 400, Wilmington, County of New Castle, Delaware 19808, and the name of its registered agent at such address is Corporation Service Company.

THIRD: The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware as it now exists or may hereafter be amended and supplemented.

FOURTH: The total number of shares of all classes of capital stock that the Corporation shall have the authority to issue is 290,000,000 shares, consisting of (i) 275,000,000 shares of common stock, $.01 par value per share (the “Common Stock”), and (ii) 15,000,000 shares of preferred stock, $.01 par value per share (the “Preferred Stock”).

the Corporation (the “New Common Stock”). Any stock certificate that, immediately prior to the Effective Time, represented shares of the Old Common Stock will, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent the number of shares of the New Common Stock as equals the product obtained by multiplying the number of shares of Old Common Stock represented by such certificate immediately prior to the Effective Time by 7.580345; provided, that each person holding of record a stock certificate or certificates that represented shares of Old Common Stock shall receive, upon surrender of such certificate or certificates, a new certificate or certificates evidencing and representing the number of shares of New Common Stock to which such person is entitled under the foregoing reclassification. No fractional shares of Common Stock shall be issued as a result of the Stock Split. In lieu of any fractional shares of Common Stock to which a stockholder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the initial public offering price per share of Common Stock.

A. Powers and Rights of Holder of Common Stock:

1. Holders of Common Stock will be entitled to one vote for each share held on all matters submitted to a vote of stockholders and will not have cumulative voting rights.

2. Holders of Common Stock are entitled to receive ratably such dividends, if any, as may be declared by our Board of Directors out of funds legally available therefor, subject to any preferential dividend rights of outstanding Preferred Stock.

4. Holders of our Common Stock have no preemptive, subscription, redemption or conversion rights.

5. If the Corporation issues any Preferred Stock, the rights, preferences and privileges of holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of the Preferred Stock.

B. Powers and Rights of Holder of Preferred Stock:
