Keep cool when choosing the right ENERGY STAR certified room air conditioner
It’s easy to assume all room air conditioners are pretty much the same, but this is not the case. ENERGY STAR certified room air conditioners, including those mounted in a window or through a wall, use about 15 percent less energy than standard models. There are also some other factors to consider before you buy.
For example, choose an ENERGY STAR certified room air conditioner that fits the space you want to cool (bigger isn’t necessarily better). Also, selecting a model with a timer offers greater temperature control, and helps save more energy by cooling the room only when needed. Finally, be sure to check the EnergyGuide label to compare energy costs before you buy.
