What do air conditioning and heat pump ratings mean?
Efficiency ratings – SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the number, the less it will cost you to operate. HSPF(Heating Seasonal Performance Factor) is a measurement similar to SEER, but it is measuring the efficiency of the heating part of a heat pump.
This stands for Seasonal Energy Efficiency Rating. The “size” of an air conditioner is rated in BTUs (British Thermal Units) or tons; however the “efficiency” of a system is rated in SEER. SEER is like mpg (miles per gallon) in a car: the higher the mpg (or SEER) the lower the gasoline (electricity or gas) bill. Santee Air Conditioning Repair
