Energy-efficient air conditioners

When the temperatures start to rise in the summer, air conditioning is usually the only way to keep your home cool and comfortable. Using an air conditioner all day can run up your energy bill, though — and isn’t very good for the environment either.

Fortunately, if you choose an energy-efficient air conditioner, you can keep your home comfortable all summer without incurring substantial energy costs. Energy-efficient air conditioners usually do a better job of regulating the temperature in a room, too, so you’re never too cold in your quest to cool off.

Are you looking for an energy-efficient air conditioner? We’ve put together a list of some of the best energy-efficient air conditioners to help keep your house cool during the next heatwave. 

How do I know if an air conditioner is energy-efficient? 

The easiest way to tell if an air conditioner is energy-efficient is to look for the Energy Star label. 

Energy Star is an initiative established by the Environmental Protection Agency to help consumers identify appliances and other products that help save money on energy costs and limit the environmental impact. To earn an Energy Star certification, an air conditioner must meet specific energy efficiency criteria set by the EPA and the US Department of Energy.
