The 6 Best Window Air Conditioners of 2022

Best Overall Window Air Conditioner: Midea U Smart Inverter Window Air Conditioner

Who it is for: People who want an ultra-quiet air conditioner that can be controlled via an app.
For whom it is not: People looking for a simple installation process.

This U-shaped window air conditioner from Midea checks all our boxes. Of all the units on our list, it has the highest Combined Energy Efficiency Rating (CEER) at 15 and the lowest noise level at 42 decibels. It is also Energy Star certified, meaning it meets the US Environmental Protection Agency’s strict energy efficiency criteria. This window air conditioner goes one step further by using nearly 38% less energy than the federal standard.

But what really sets it apart is its innovative design: the U-shaped notch allows you to open and close your window without uninstalling the air conditioner. Not only does this give you the freedom to let in cool air whenever you want, but it also means the compressor (the noisy part of an air conditioner) is on the outside, with the window acting as a noise barrier. .

The Midea U Smart model comes in three different sizes – 8,000, 10,000, and 12,000 BTUs – that can cool rooms ranging from 350 to 550 square feet, depending on what you buy. Inverter technology helps control your device’s output by constantly running it at a lower setting, making it more energy efficient.

This window air conditioner can even connect to Wi-Fi, so you can control it from your smartphone and use voice commands via Google Assistant or Amazon Alexa. This is an especially useful feature if you have pets as you can adjust the temperature for them even when you’re away from home.

In terms of maintenance, this air conditioner comes with a washable and removable filter and has an indicator light that reminds you to clean it. One downside is that the installation process can be a bit more involved than many other window units, as you have to install the included mounting bracket. In addition to the instructions for use, you can refer to the brand instructions helpful video tutorial to facilitate the process. But we think this window air conditioner is worth it because of its unique design, low noise level and energy efficiency.
