As of 2015, Goodman offers lifetime limited warranties on its air conditioner compressors and furnace heat exchangers; a 10-year limited warranty covers parts. The company also replaces certain gas furnaces under a 10-year limited warranty. Warranty coverage details for each product are available on GoodmanMfg.com and from the dealer.
Within 60 days of the unit's installation, a purchaser must register the unit online to activate the 10-year and lifetime warranties, unless the purchaser resides in California or Quebec. Under the warranty, the company replaces a purchaser's furnace with a new furnace comparable to the old one if its heat exchanger fails during the first 10 years, as long as the purchaser owns the home.
