Question

How much energy does an air conditioner with an 9.7 EER save as opposed to a 10.7 EER?

Answer 1

EER stands for Energy Efficiency Ratio. The EER rating for an air conditioner is calculated by dividing the BTU (British Thermal Units) rating by the wattage. For example, a 12,000-BTU air conditioner that uses 1,200 watts has an EER rating of 10 (12,000/1,200 = 10).

What's an Energy Efficiency Ratio (EER)? The energy efficiency ratio is the ratio of the cooling energy to the power input energy of the cooling unit. ... As an example, an HVAC unit that has 10,000 BTU of cooling energy and 1,200 watts of power input energy has an EER of 8.3, or 10,000 divided by 1,200.
