Compare The Cost To Operate
If low operating costs are important to you, then purchase a unit with a high EER. Energy Efficiency Ratio (EER) is the ratio of the cooling output in BTU/h divided by the power consumption in Watts. The higher the EER, the more energy efficient the air conditioner
You will see bright yellow Department of Energy EnergyGuide labels on all room air conditioners offered for sale in the U.S. Each EnergyGuide label gives you an estimated yearly operating cost of that model at various utility rates and hours of use. If you want to calculate the cost to operate a particular model using your own utility rate and hours of operation, use either formula below:
 |
|
|
BTU/h x (Electricity rate in KWH) |
x hours of operation |
= Cost of Operation |
EER x 1000 |
|
|
|
|
Watts x (Electricity rate in KWH) |
x hours of operation |
= Cost of Operation |
