Window air conditioners are great for cooling apartments, dorm rooms, or even rooms in a house. While they require dedicated mounting solutions and aren't as simple to set up as a portable A/C unit, their design offers some significant advantages. Since the hottest and noisiest components are outside of the space you're cooling, they generally operate and cool much more efficiently. This configuration helps keep your utility bills low and your living environment comfortable.
Of course, not all window A/Cs are built the same, so you'll want to look for a few key characteristics when shopping. The best window air conditioners use inverter compressors that modulate their output based on load requirements and offer ample capacity, making them versatile appliances that can cool large or small rooms. Noise is a big consideration, too, as no one wants a loud unit drowning out their TV or making it impossible to sleep. Other nice-to-haves include remote control, whether via a remote or an application, and smart home integration.
We've tested over 20 air conditioners, and below are our recommendations for the best window air conditioners based on performance, pricing, and general availability. If you're short on window space and need a portable unit, check out our recommendations for the best portable air conditioners. Alternatively, if you need an air purifier for your bedroom, see our recommendations for the best air conditioners for bedrooms.

Best Window Air Conditioner
Large Room8.4Bedroom/Small Room7.9Combined Efficiency7.8Oversizing Tolerance7.4Noise9.0Type:Window A/CAdvertised Capacity (DOE):12,000 BTU/hrTested Capacity:12,038 BTU/hr (3,530 W)See all our test resultsCompressor Technology:InverterThe Midea U-Shaped MAW12V1QWT is the best window air conditioner we've tested. This high-end model delivers excellent overall cooling capacity, easily handling larger spaces such as open-concept apartments or spacious living rooms. It runs quietly and efficiently thanks to its inverter compressor, which adjusts its speed gradually instead of constantly turning on and off, so it avoids sudden bursts of noise and uses less energy over time. Its U-shaped design is also a standout feature, as it lets you partially open your window while the unit is installed, helping bring in fresh air and reducing the blocked-in feeling that most window A/Cs create. It also supports remote operation through the Midea Air app, along with Amazon Alexa and Google Assistant integration, so you can adjust settings from your phone or with voice commands instead of walking over to the unit.
That said, there are some limitations to this unit's design. While you can use it in a smaller bedroom, it isn't quite as well-suited to those spaces; its performance is less consistent in tighter or more enclosed areas, leading to larger swings in humidity. Installation is also more involved than with most standard window units due to its U-shaped design, and its bulky, heavy build can make setup more cumbersome, particularly if you're installing it on your own or in a tight window space. Overall, it's a highly capable and efficient unit, but it's best suited to larger spaces where its performance and design are fully put to use.

Best Mid-Range Window Air Conditioner
Large Room7.6Bedroom/Small Room5.9Combined Efficiency6.6Oversizing Tolerance5.7Noise5.3Type:Window A/CAdvertised Capacity (DOE):14,000 BTU/hrTested Capacity:14,646 BTU/hr (4,295 W)See all our test resultsCompressor Technology:Non-InverterIf you're looking for a more affordable alternative to the Midea U-Shaped MAW12V1QWT and only need to cool large spaces, the Hisense AW1422CW1W is worth considering. It's a high-capacity unit that cools large rooms very quickly, making it a good fit for bigger living rooms or open areas. It also includes convenient features like Wi-Fi connectivity, app control, and voice assistant support, so you can adjust settings without needing to be right next to the unit.
That said, its non-inverter compressor makes it less flexible than the Midea. Once it reaches your set temperature, the compressor shuts off for longer periods, leading to noticeable swings in both temperature and humidity before kicking back on. In practice, this can leave the room feeling heavy or clammy, especially in smaller spaces that cannot better absorb those fluctuations. It's also less efficient overall and fairly noisy, even at lower settings. As a result, it works best in larger rooms where its high capacity is actually needed. Overall, it's a solid pick for cooling big areas quickly, but it isn't versatile enough to work in smaller spaces

Best Budget Window Air Conditioner
Large Room7.0Bedroom/Small Room7.7Combined Efficiency8.0Oversizing Tolerance7.6Noise7.5Type:Window A/CAdvertised Capacity (DOE):5,000 BTU/hrTested Capacity:4,809 BTU/hr (1,410 W)See all our test resultsCompressor Technology:Non-InverterThe Frigidaire FHWC054TE1 is the best window A/C we've tested at a budget price point. While the Hisense AW1422CW1W is geared toward cooling large spaces, this model is your huckleberry if you only need an A/C for a smaller office or bedroom, offering simple, reliable cooling without driving up your energy bill. Its power draw is comparatively low in real-world use, and its compressor cycles quickly enough in appropriately sized spaces to maintain a steady temperature and humidity level without noticeable swings. It's also easy to use overall, with a remote control for convenient adjustments and a dehumidification-only setting for added flexibility.
Like the AW1422CW1W, it doesn't use an inverter compressor, so it's less efficient over time and can't maintain conditions as smoothly as inverter-based models. Its limited capacity makes it wholly unsuited for larger rooms, and its white-on-white digital display can be difficult to read under direct sunlight. Still, it's a straightforward, cost-effective option that will get the easily get the job done if you're cooling a smaller space.

Frigidaire FFRA051WAE:
The Frigidaire FFRA051WAE is a basic window A/C unit like the Frigidaire FHWC054TE1, which works well for small spaces, has a low power draw, and is compact. However, it's noisier, lacks additional features, and its non-inverter compressor can cause slight humidity fluctuations.
