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 Excellent replacement After 28 years of my natural gas furnace was in need of replacement. My installer recommended to use a Goodman products and we were very pleased with how quickly he was able to reinstall the newer unit and get us back into service. Also the matching cooling system was easy to attach to the air handler / furnace. Overall extremely satisfied.

Rated 5 out of 5 by from Great system for the home cooling and heating We now own a 2 ton, 3 ton, and 4 ton Goodman furnace and air conditioners for our homes. Our Maryland home's system was in need of replacement so we contacted Mr. Sanford. He did a professional installation and ensured system integrity. We highly recommend his services for anyone needing replacement systems for their homes. M/M C.L. Wells, Sr.
