Amana air conditioners and heat pumps use chlorine free R-410A refrigerant.  All of these units feature what we believe to be the most comprehensive warranty coverage of any air conditioner or heat pump on the market. They offer Lifetime Limited Warranty* protection for the compressor to the original, registered, single-family, homeowner of a properly matched system using these high-efficiency air conditioners and heat pumps. If the original owner should have a compressor failure, we will replace the air conditioner or heat pump with a comparable Amana® brand product.
