Room Air Conditioners

Receive a $40 rebate on ENERGY STAR® certified models.

In the summer months, room air conditioners, such as window units, can help keep the spaces in your home cool and comfortable. By using an ENERGY STAR® certified room air conditioner, you can avoid the heat, while also avoiding energy waste. A certified model uses 10% less energy than a non-certified model, which means you could save more than $60 over the lifetime of the unit.
