EER refers to the Energy Efficiency Ratio, and indicates the quantity of energy utilized. The higher the EER, the less energy is used by the air conditioner, resulting ultimately in savings in the cost of electricity to the purchaser. Between 8.2 and 10.5, is usually the range for EER numbers.
Carrier, Kenmore, Samsung, Sharp, LG, Panasonic and Driedrich are the market leaders in the air conditioner industry.
