What is SEER?
The efficiency of heat pumps and air conditioners is expressed by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER number, the more cooling you will get for your money. The SEER will be listed on the yellow and black Energy Guide located on the unit.

The SEER is defined as the total cooling output in British thermal units or BTU provided by the unit during its normal annual usage period divided by its total energy input (in watt-hours during the same period).
