The 7 Best Window-Mounted Air Conditioners for Staying Cool and Comfortable

The humble window air conditioner, long scorned for its noisy, rattling inefficiency, has undergone a revolution. New models cool down a room more quickly thanks to improved fan and compressor designs, with better sound dampening features and improved air flow, so they operate more quietly.

And many models can be controlled remotely using an app on your phone, allowing you to program the appliance’s operation and alter its schedule if the weather takes a turn—for the better or for the worse. And there are a few appliances that offer voice control: just tell the appliance what you want it to do.

How We Chose These Air Conditioners

To select these appliances, we tested some and surveyed the market for others that we didn’t test, looking for key features that point to higher construction quality, energy efficiency and amperage (current draw) relative to the square feet of cooling area for which the air conditioner is rated.

Read reviews of our top air conditioners below, and keep scrolling for more information on how your air conditioner works and how to keep it working in top condition for many summers to come.
