Be sure to understand some basics of air conditioning systems before you make that all-important purchase!

SEER: SEER (Seasonal Energy Efficiency Ratio) is the measure of efficiency by which the cooling process of air conditioners and heat pumps is rated. The higher the SEER rating, the greater the efficiency – and therefore greater potential energy savings.

Single-Stage Compressor: Single Stage Compressors operate on a basic on/off principle. Each time your thermostat calls for cooling, your air conditioning system comes on at 100% capacity.

Two-Stage Compressor: Two Stage Compressors are capable of two levels of operation, a low stage and a high stage. Properly sized equipment will operate 80% of the time in low stage, enhancing efficiency and comfort with lower humidity levels and quieter operation. It’s almost like getting two air conditioners in one system.

Refrigerant: R-410a (also known as Puron) is a more environmentally-sound refrigerant designed to not harm the earth’s ozone layer. Federal law requires that all manufacturers phase out R-22 (also known as Freon) and other ozone-depleting refrigerants in the next few years. R-410a refrigerant is approved by the US Environmental Protection Agency as a replacement for R-22.

Dehumidification Mode: The process of varying air flow and compressor operation can allow certain air conditioning applications to manage more precise indoor humidity levels.
