What You Need to Know About Heating and Cooling System Efficiency Ratings

Last updated 4 years ago

Choosing a new HVAC system is a decision that will affect your life for many years to come. An energy efficient air conditioner or heating unit not only saves you money on your monthly energy bills—it can help contribute to a more sustainable lifestyle. To select the appliance that meets your climate control needs and your budget, learn about industry-standard heating and cooling system efficiency ratings below:

Annual Fuel Utilization Efficiency

Annual Fuel Utilization Efficiency (AFUE) ratings for gas and oil furnaces tell you how much of the fuel that the unit burns is actually converted into heat. Many older furnaces produce harmful emissions when they run, and turn a relatively small amount of the fuel into heat. The minimum industry requirement for all new furnaces is an AFUE of 78%, and top-of-the-line HVAC manufacturers such as Carrier produce units with AFUE values of up to 96%.

Heating Seasonal Performance Factor

Heat pumps have something called the Heating Seasonal Performance Factor (HSPF). The HSPF expresses the number of BTUs of heat the pump produces per watt hour of electricity it consumes. The higher the HSPF, the more efficiently the pump will heat your home in colder weather. Industry standards require all heat pumps to operate at a minimum HSPF of 6.8.

Seasonal Energy Efficiency Ratio

The Air Conditioning, Heating and Refrigeration Institute assigns all new air conditioners and heat pumps a Seasonal Energy Efficiency Ratio (SEER). The opposite of HSPF, the SEER number tells you how many BTUs of heat the air conditioner removes per watt hour of operation. The minimum SEER for new air conditioners is 13, and companies such as Carrier make units with SEER ratings up to 21.
