Best Window Air Conditioners for the Hot Days Ahead

Top choices from Consumer Reports' tests

All of the window air conditioners in Consumer Reports' latest tests do a good enough job at keeping you cool. What distinguishes one window unit from another is how quickly and quietly it cools a room—and how easy it is to operate.

Even if your home has central air conditioning, you might want to consider a room unit to cool areas not served by the main system, such as a home office or a finished room in the attic. If you do, go with a window air conditioner. They're a better choice than portable air conditioners, which struggled in our tests.

And you don’t have to pay a lot to get heat relief. Most window air conditioners in our tests range from $150 to $400. The outlier? The Friedrich Kuhl SQO8N10D, $710, a strong performer with a streamlined look.

To help a window unit run more efficiently, look for a model equipped with insulating panels. "Most new window ACs come with panels you place over the plastic adjustable side panels to boost efficiency," says Chris Regan, CR's senior test engineer for air conditioners. Adding weatherstripping around the perimeter will also prevent air from leaking in or out.

Below, grouped alphabetically by the size room they can cool, are some of CR's top-performing window air conditioners. For more on getting the best fit, find out how to size a window air conditioner.

For Small Rooms (100-300 sq. ft.)
Amana AMAP061BW

Amana AMAP061BW

CR's take: The Amana AMAP061BW, a newcomer to our test labs, turns out to be a cool addition. It capably cooled the test chamber and was a champ at recovering from brownout conditions when voltage is low. It comes equipped with a remote control, built-in timer, and dirty-filter indicator. But it's a bit noisy on both low and high settings.

    GE AHM05LW

    GE AHM05LW

    CR's take: A CR Best Buy, the GE AHM05LW scored well for comfort but, like the Amana, can be a bit noisy at any speed. It quickly recovered from brownout conditions and has a full suite of features including a remote, built-in timer, and dirty-filter indicator.

      For Midsized Rooms (250-400 sq. ft.)
      Friedrich Kuhl SQO8N10D

      Friedrich Kuhl SQO8N10D

      CR's take: The Friedrich Kuhl SQO8N10D makes an effort to blend in with your décor with a flat front instead of a grille. It aced the cooling test and runs quietly on low speeds, although gets a tad noisier on high. Controls are a cinch to use, and it's equipped with all the conveniences of a timer, remote, and more. This 85-pound model comes with a slide-out chassis that makes it easier to install.

        Kenmore 77080

        Kenmore 77080

        CR's take: With capable scores for cooling, and intuitive controls, the Kenmore 77080 is a good bet for a midsized room. It's pretty quiet on the lowest setting but you'll hear it running when you crank it up to high. At 52 pounds it weighs considerably less than the Friedrich. It comes with a remote, built-in timer, and dirty-filter indicator.

          5
          For Large Rooms (350-650 sq. ft.)
          LG LW1216ER

          LG LW1216ER

          CR's take: A CR Best Buy, the large, feature-filled LG LW1216ER has digital controls, and cooling is top-notch. It weighs 85 pounds, but its slide-out chassis makes it easy to install. It has all the convenience features—remote control, built-in timer, and dirty-filter indicator. It's a good choice for a large living area.

            6
            SPT  WA-12FMS1

            SPT  WA-12FMS1

            CR's take: Another candidate for large spaces, the SPT WA-12FMS1 is top-notch at cooling, although it's noisier than the LG at both low and high speeds. On the plus side, our testers found the controls were more intuitive. It also comes with a full range of features including a remote, timer, and dirty-filter indicator.
