Finding an Energy Efficient Room Air Conditioner


I’m in the market for a new room air conditioner. Got any tips on what to look for?

The main thing to look for is the Energy Star label, which tells you a unit uses at least 10 percent less energy than conventional models. Energy Star qualified room air conditioners come in a range of sizes (you can browse the program’s list of qualified room air conditioners for the right match), and often include timers for even better control over room temperature and the energy you’re using.

Also, before going shopping, follow the Energy Star room AC sizing guidelines to accurately calculate the unit size you’ll need, because going too big or too small can lead to an uncomfortable indoor climate and reduce the energy savings you were after in the first place.
