The energy efficiency of an Amana heat pump can range between 13 to 18 SEER, depending on the model. The least efficient Amana heat pump models are the ANZ13 and ASZ13, with SEER ratings of 13, and the most efficient is the ASZC18, with a SEER rating up to 18.
As of 2015, each Amana heater is designed to include nine distinct parts, including a compressor sound blanket and the R-410A refrigerant. The compressor sound blanket functions to reduce the sound of the machine's compressor. The R-410A refrigerant used in an Amana heat pump is considered to be environmentally friendly as it does not contain chlorine.
