When deciding on the best window AC unit, efficiency, cooling capacity, and ease of installation are all important considerations. Look for models with a high Energy Efficiency Ratio (EER) to ensure you get the most cooling power for your energy. Consider the size of the room where the AC will be installed, as larger spaces require higher British Thermal Units (BTUs). Another important consideration is noise level, particularly if you intend to install the unit in a bedroom or living room where quiet operation is preferred.

Our carefully chosen list of the best window air conditioners considers all of these factors, providing you with a selection of high-performing models to suit a variety of needs and budgets. Whether you need a powerful unit to cool a large living area or a compact option for a smaller room, we have you covered.

Best Overall Window AC

Midea U MAW08V1QWT

The Midea U MAW08V1QWT is simply the quietest air conditioner we’ve ever tested, but that’s not the only thing that sets it apart. The smart-home-compatible, Energy Star-certified unit has an inverter compressor, so it consumes roughly half the energy of a non-inverter AC. This model also has a unique, U-shaped design that allows you to continue opening and closing your window (in contrast, traditional air conditioners typically lock your entire window in a closed position). However, there is a catch: when compared to other air conditioners, the installation process is significantly more frustrating.

Frigidaire FHWW083WBE

We recommend the Frigidaire FHWW083WBE (or one of its nearly identical predecessors) as a dependable and cost-effective basic window air conditioner. It is quieter than most other non-inverter air conditioners, and it cools the room quickly and effectively. Furthermore, it is typically less expensive than our other recommendations while providing comparable performance and smart-home capabilities.

Windmill AC with WhisperTech

The Windmill AC with WhisperTech is one of the most aesthetically pleasing air conditioners we’ve ever tested, with rounded corners and subtle indicator lights that won’t keep you awake at night. It was also the simplest to install, with a pre-installed frame that fits perfectly in the window and a stylish plastic cover over the back (to avoid cutting your hands on those razor-sharp exhaust fins). You can even add a custom colour panel to the front grille. It also has an inverter compressor, making it nearly as quiet as our top pick while remaining just as efficient.

Frigidaire Gallery GHWQ083WC1

Efficient, quiet, and powerful cooling for smaller spaces, the Frigidaire Gallery GHWQ083WC1 is a top choice for comfort.

The Frigidaire Gallery GHWQ083WC1 is an inverter-style air conditioner that is slightly louder than our top pick, but it is still barely audible in a room unless the fan is turned on high. Compared to other air conditioners we’ve tested, this one provides more consistent cooling throughout the room. The LED display on the control panel turns off automatically after a few seconds (which is useful when sleeping but annoying when checking the settings). Also, the smart-home app can be a little glitchy at times. Despite its flaws, this air conditioner is one of the best models available.

GE Profile ClearView PHNT10CC

Featuring advanced cooling technology and a sleek design, the GE Profile ClearView PHNT10CC offers exceptional performance and style for your home.

The 10,000-Btu GE Profile Clearview PHNT10CC is an Energy Star-certified inverter air conditioner that can fill a room up to 450 square feet while taking up only about 4 inches of window space. Instead of balancing precariously on top of the sill, this N-shaped model hangs down over the wall, freeing up the window above it. The AC does stick out into the room (about 9 inches), and you may need assistance lifting it over the windowsill.
