Cooling Terminology

R22 OR R410A

These are refrigerants commonly used in residential air conditioners.  R22 has always been used, and will be manufactured until 2010, a replacement refrigerant (RNU22) which is now available will be used for the existing R22 equipment when R22 is no longer available.  R410A is the new environmentally friendly refrigerant now available in certain models.

Two Stage

This refers to air conditioners that have two stages of cooling, in most cases there will be two compressors. One compressor will run most of the time and the second one will come on when a high demand for cooling is determined by the thermostat.  This is designed to give you maximum efficiency by using only what you need.
