Similarly, what is a good energy efficiency rating for an air conditioner? EER (Energy Efficiency Ratio) A higher number means a more energy efficient system. Look for an EER rating greater than 11.6 and up to 16.2, for high-efficiency operation when the weather is at its hottest. Air conditioner energy efficiency ratings are a bit like miles per gallon (MPG) ratings for cars.

Likewise, 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. However, a higher rating is usually accompanied by a higher price.
