What is an ENERGY STAR qualified air conditioner?
Air conditioners that receive an Energy Star certification boast features to maximize energy efficiency, thus saving on utility bills and reducing the appliance’s carbon footprint. The actual metrics vary according to type, but Energy Star-certified AC units include higher seasonal energy efficiency ratios (SEER) and energy efficiency ratios (EER) ratings and can use anywhere from eight to 10 percent less energy during use than regular models.
