EER (Energy Efficiency Ratio) EER is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level. The higher the EER, the more efficient the system. It is calculated by dividing the cooling capacity in BTUs per hour (BTUH) by the power input in watts. EER is expressed as BTUH/watts.
