Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

Goodman Global, Inc. (the “Company”) is providing the following guidance for the rest of 2010 and the full year 2011:

a) for the three months ended September 30, 2010, net sales are expected to range between $525 million to $535 million, as compared to $530 million for the corresponding period in 2009, and operating profit is expected to range between $84 million and $89 million, as compared to $99 million for the corresponding period in 2009,

b) for the nine months ended September 30, 2010, net sales are expected to be in the range of $1,535 million to $1,545 million, as compared to $1,409 million for the corresponding period in 2009, and operating profit is expected to range between $259 million and $264 million, as compared to $224 million for the corresponding period in 2009,

c) for the three months ending December 31, 2010, net sales are expected to range between $415 million to $425 million, as compared to $418 million for the corresponding period in 2009. Operating profit is expected to range between $40 million and $45 million, as compared to $51 million for the corresponding period in 2009,

d) for the year ending December 31, 2010, net sales are expected to range between $1,950 million and $1,970 million, as compared to $1,851 million for the corresponding period in 2009, and operating profit is expected to range between $300 million and $305 million, as compared to $276 million for the year ended December 31, 2009,

e) annual depreciation and amortization for the year ended December 31, 2010 is expected to range between $46 million and $48 million, as compared to $48 million for the year ended December 31, 2009,

f) at September 30, 2010, cash and cash equivalents are expected to range between $200 million and $210 million,

g) for 2011, net sales are expected to range between $2,030 million and $2,130 million, and

h) for 2011, operating profit is expected to range between $315 million and $335 million.

Net sales for the three months ending September 30, 2010 are expected to be roughly flat compared with the corresponding period in 2009. The expected decline in third quarter 2010 operating profit is driven primarily by an estimated $18 million increase in commodity costs, which includes incremental costs borne by the Company related to proposed tariffs on imported copper tubing. These expenses are partially offset by an expected $8 million margin benefit from favorable sales volume and product mix and an expected $5 million decline in selling, general and administrative expenses. Additionally, the Company expects results to be unfavorably impacted by higher logistics cost, including increased fuel costs and trucking rates, and higher promotional expenses including extended service contracts promotions.

The expected increase in net sales for the first nine months of 2010 is driven primarily by favorable industry conditions and product mix. The expected increase in operating profit for the nine months ending September 30, 2010 and the year ending December 31, 2010, as compared to the corresponding prior year periods is primarily due to improved industry conditions, especially during the first half of 2010, which led to higher sales volumes as compared to the prior periods, partially offset by the above mentioned commodity cost increases, including incremental costs borne by the Company related to proposed tariffs on imported copper tubing and expenses associated with various promotional activities during the period.

Net sales in the fourth quarter of 2010 are expected to be roughly flat as compared to corresponding period in 2009. The expected decline in fourth quarter 2010 operating profit is driven primarily by an estimated increase in commodity costs of approximately $9 million, including

incremental costs borne by the Company related to proposed tariffs on imported copper tubing. Also contributing to the decline is an expected reduction in factory utilization and efficiencies, which are estimated to have an $8 million adverse impact, along with unfavorable logistics costs including increased fuel costs and trucking rates. These expenses are partially offset by an expected $6 million margin benefit from favorable sales volume and product mix and an expected $7 million decline in selling, general and administrative expenses. Additionally, the Company expects results to be unfavorably impacted by reduced supplier rebates on purchased components and an increase in other input costs.

The Company believes that expected increased net sales for 2011 will be driven by modest industry shipment growth and market share gain.

The Company expects operating profit for 2011 to be favorably impacted by higher sales volume offset by unfavorable product mix due to the expiration of the Federal tax credits on higher efficiency equipment. Additionally, the Company forecasts for 2011 an unfavorable impact from higher effective commodity costs, including metals and fuel costs, which the Company expects to partially offset with cost-reducing product designs and factory efficiencies. The Company also expects in 2011 to favorably leverage selling, general and administrative expenses while continuing to invest in expanding the company-operated distribution network.

The Company has not yet completed preparation of its financial statements for the three and nine months ended September 30, 2010. Accordingly, the statements in this Report relating to our financial performance or condition as of September 30, 2010 or for any period ending with or including the three and nine months ended September 30, 2010 necessarily reflect the Company’s current estimates, which are based on currently available information and are subject to change.

The Company estimates that from 2003 through the twelve months ended June 30, 2010 it gained approximately seven market share points in the U.S. residential and light commercial HVAC industry (consisting of gas furnaces, package terminal units and compressor bearing units 5.4 tons in capacity and smaller).
