 If the compressor breaks to the original registered homeowner, we'll replace the entire unit for as long as you own the home. So choose the Amana brand and make the next air conditioner you buy the last. To receive the lifetime unit replacement limited warranty, online registration must be completed within 60 days of installation, except in California or Quebec. Full warranty details available at amana-hac.com. Amana, lasts and lasts and lasts.
