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 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.

Rated 5 out of 5 by from No more bundling in winter!! Purchased this gas system about five (5) years ago. Same efficiency today--just like the day was installed. Plus we have not had the need for any service calls. In fact, we like the Goodman furnace so much that we have now installed a new Goodman AC system. It was installed on a VERY HOT summer day and cooled our home in short order. Looking forward to many cool summers & warm winters!

Rated 5 out of 5 by from Satisfied customer I bought this 5 ton unit along with a new coil and furnace. We are currently having a heat wave and I am comfortable in my house. Both my wife and I laugh because we are so cool at night we have a blanket on our bed. I am thoroughly satisfied.
