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.

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 Bang for the Buck After some research, I found the efficiency, warranty, and reliability of the Goodman furnace to be comparable to other manufacturers. However, Goodman's price was substantially less. I had a great experience with my installer. I've only owned the furnace a few days, but so far so good.

Rated 4 out of 5 by from Working like a champ I bought this right before xmas and thank God I did...my heater old as dirt was broken and needed a new one it's been working like a champ so far the 4.0 rating is because I thought it would be a bit quieter...not as bad as my old one but with the 25 second delay in coming on it can be a tiny bit annoying...other than that Great Product!!!

Rated 2 out of 5 by from Heats well, but VERY NOISY after 3 weeks of instal Heats well, but after just 3 weeks of being installed, it started to make a lot of noise, as if the fan has suddenly become much noisier than it was before. This is in a brand new house, everything is brand new. House was built and construction finished just 1 or 2 weeks before we moved in. We are the first occupying the house. All furnace filters are new (3 weeks old). There is no reason why the furnace has become so noisy so quickly. BTW, an 80% efficiency in a gas heating unit is probably at the low end as of today (Nov. 2014)

Rated 5 out of 5 by from Great Value for your Money! I just recently purchased a gas furnace for one of my rent houses. This is the second Goodman purchase I have made in the last six months. I, earlier, purchased a new air conditioner unit for my real estate office. I have recommended Air Plus (the local Goodman dealer/serviceman) to several home owners who are also well pleased. I own several rental homes and do a lot of heat and air business. I know that the product is a great value and highly recommend Goodman heat and air products.

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 Very pleased so far! This unit replaced an aging hydro-heat unit that I was worried would spring a leak in my attic. I am glad to have the water heating unit out, and I am very pleased with this unit. It seems to heat much faster and feel warmer than the hydro-heat unit. It seems to run for shorter periods of time, also. I am hoping to have lower energy bills as a result.
