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.

Additional Information

Before purchasing this appliance, read important information about its estimated annual energy consumption, yearly operating cost, or energy efficiency rating that is available from your retailer.

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 Great equipment with Value & Increased Efficiency Brought a new Goodman HVAC system with energy efficiency. Jerry Kelly team members recommended the "Goodman" brand and not being familiar with it, I was extremely reluctant. Did some research and found the reviews and industry feedback was outstanding, so we went ahead and purchased the new HVAC system for our home. Super quiet, Well Made and Better Energy Efficiency. This system is a beast compared to my old system with an additional benefit of not hearing it during start up and operation. Additionally, it is back by a great warranty.
