Outstanding Warranty Protection

The heat exchanger in the furnace is covered by a Lifetime Limited Warranty for the original, registered homeowner and if it fails during the first 10 years of ownership, we will replace the entire unit. This furnace also has a 10-Year Parts Limited Warranty on all other functional parts. For a full description of all warranties applicable to this product, please review the consumer brochure or product warranty by clicking on the links above.

Unlike conventional, single-stage furnace technology, Goodman’s technology helps eliminate the temperature swings resulting from abrupt, high-stage stops and starts of the furnace by operating at a low heating state the majority of the time. This gas furnace has an AFUE rating of 80%, which means that 80 cents of every $1.00 of heating energy expense warms your home.

Rated 5 out of 5 by from Value, confidence and satisfaction Its 12 degrees outside and I'm warm and comfortable. My new Goodman 2 stage gas furnace is quiet, efficient and effective. The installation team determined the correct size furnace for my house. My new furnace runs less often, heats more efficiently and the house seems warmer. The Goodman 2 stage was affordable and I'm highly satisfied with the results.

Rated 5 out of 5 by from Heat and Air is so improved! Replaced old A/C and furnace. I didn't realize how significant these units would improve heat and cooling inside my home. It's a huge difference

Rated 5 out of 5 by from Great Value I was not familiar with the Goodman product. My HVAC contractor recommended it. I did some online research and found overwhelmingly positive reports on the product. The cost for both product and installation was a much better value that other contractors offered and the warranty coverage was excellent. I'm looking forward to many years of efficient service from this new furnace.

Rated 4 out of 5 by from Dealer recommended I bought this heater about 2 weeks ago during an emergency. Fortunately, I had already research a replacement heater and had a price in hand when the need arose. The installer was timely and efficient; and got me out of a terrible jam.
