What Makes an Air Conditioner Energy Efficient?
Understanding what makes an air conditioner energy efficient helps you make the right investment. Energy efficiency is measured using key factors like EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio).
Energy Star air conditioner labels indicate that a unit meets the U.S. Department of Energy’s strict efficiency standards. The higher the SEER and EER ratings, the better the energy performance of your air conditioner.
