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 Great! We had this furnace installed after ours died in the middle of the night in subzero temperatures. It appeared that the furnace was easy to install, and has been great since installation. It is very quiet and heats our home quickly!

Rated 5 out of 5 by from Nice looking runs very quite. I purchased this as a replacement to an older model. I could tell right away the difference in the flow of heat in my house. It runs quieter then the older one. The upstairs is toasty warm no more drafty feelings.
