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 4 out of 5 by from Easy install My 25 year old furnace went out last year and I had to use space heaters to get through the winter. This furnace was low cost and more efficient than my old furnace. I had installed professionally. After all was aid and done the total package was about one 3rd of what local heating companies were quoting. Furnace works good now that I switched the inside panel to 2 from one drive and reversed the fan motor speed to low. It now blows warmer air.

Rated 5 out of 5 by from Dependable and Efficient We owned a previous Goodman furnace for many years. The equipment was dependable and efficient. Simple to operate. When time came to replace, naturally our choice was to replace with another Goodman unit. Great product.

Rated 5 out of 5 by from Go for 2 stage 2 stage is flexible because it runs on single stage for a long time and sometime kicks in stage 2.
