EER

EER stands for Energy Efficiency Ratio (also commonly expressed as Energy Efficiency Rating), measure the efficiency with which a product uses energy to function. It is calculated by dividing a product's BTU output by its wattage.

 

How is EER calculated?

The Energy Efficiency Ratio of a heating or cooling system is usually calculated by dividing the heat output of the system by the power input.

The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage.

 

What is the best EER for air conditioner?

For example, if a 10,000-BTU Air Conditioner consumes 1,200 watts, its rating is 8.3 (10,000 BTU/1,200 watts). The higher the rating is, the more efficient the Air Conditioning unit is.
