When it comes to air conditioning what does SEER mean?
SEER is an acronym for Seasonal Energy Efficiency Ratio which is defined by the Air Conditioning, Heating and Refrigeration Institute in its standard ARI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump as the total heat removed from the conditioned space during the annual cooling season, expressed in Btu’s, divided by the total electrical energy consumed by the air conditioner or heat pump during the same season, expressed in watt-hours.
SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system?s energy efficiency at peak day operations. Both ratings are important when choosing a product. Heat Seasonal Performance Factor (HSPF) is the most commonly used measure of a heat pumps heating efficiency. A rating of 8 HSPF is considered high efficiency.
The Bottom Line is this; the higher the unit’s SEER and HSPF ratings the more energy efficient it is.
