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. With detailed reviews and specifications, you can easily compare different models and select the best one for your needs. Say goodbye to hot summer days and nights with our comprehensive guide to the best window AC units on the market.

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.
Reasons to buy:
- High energy efficiency (EER 15.0)
- Quiet operation (42 dBA)
- Smart home compatibility (Alexa, Google Assistant)
- Wi-Fi enabled
- Easy installation
- Effective cooling (up to 350 sq. ft.)
Reasons to avoid:

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.

GE Profile ClearView PHNT10CC
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.
