Amana ASZ18 Heat Pump Review

The Amana ASZ18 Heat Pump is Amanas premiere heat pump reporting an efficiency of 18 SEER for air conditioning mode and 9.5 HSPF for heating mode. One of the best features for the Amana ASZ18 heat pump aside from the reported efficiency rating is the warranty that comes with the compressor. Amana offers a lifetime limited warranty for the compressor in the Amana ASZ18 heat pump with the remaining parts covered by a 10 year limited warranty. The ASZ18 Amana heat pump uses R410-A and High Performance HVAC recommends to all our site users that when they purchase a new heat pump or air conditioner they purchase one with R-410-A. Some features of the Amana ASX18 heat pump are:

• R-410A Refrigerant - in long run this will save you money with the phasing out of R-22 and the skyrocketing cost of R-22.


• Two-Stage Scroll Compressor - this allows you to have two-stages of operation in the cooling and the heating mode so when the temperatures are mild the unit will run at the lower speed using less energy


• Good insulation around the compressor for quiet operation


• High and Low pressure switches - this should be standard in all air conditioner and heat pumps. It will save you if their is ever a failure of a component or a refrigerant loss. These two switches basically protect the compressor if their is a problem


• Charged for 15' of lineset - this is a departure from what manufacturers include with air conditioner and heat pump systems. Typical with R-22 refrigerant is enough refrigerant for a lineset of 25'.


• Bi-Flow liquid line filter drier which is another industry standard


• Liquid refrigerant return protection - yes, it is called an accumulator and every sane heat pump manufacturer includes accumulators in all their heat pumps.

This is a good heat pump and Amana has a good reputation and backs their equipment up with great warranties including this heat pump.
