SEER = Seasonal Energy Efficiency Rating: A rating that denotes the efficiency of air conditioning equipment. The higher the SEER, the more efficient the unit and the lower the operating cost.
EER = Energy Efficiency Rating: The ratio of an air conditioning unit’s cooling capacity in British thermal units (Btus) per hour to the total electrical input in watts.
HSPF = Heating Seasonal Performance Factor: The total heating output of a heat pump in Btus during its normal usage period for heating, as divided by the total electrical energy input in watt-hours during the same period.
