Midea U inverter window air conditioner

A modern-looking unit

This U-shaped air conditioner from Midea lets the window rest between the compressor and air vent. This helps dampen outside noise so it's quieter inside. It also allows you to continue using the window, so fresh air is available whenever you please.

Pros:

  • Can be controlled via WiFi
  • Doesn't block window usage
  • Has a timer

Cons:

  • May be difficult to install

Because this is a smart unit, you can adjust the settings over WiFi from your Android or iOS phone or via an Alexa or Google smart assistant. You can choose either cooling mode or simply use the fan. This Midea U window air conditioner is difficult to install, even with the included instructions and step-by-step video.

What type of air conditioner do you need?

Why you can trust Real Homes Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

There are two main types of air conditioners; Evaporative cooling (swamp coolers) and true air conditioners.

If you live in a very hot and dry place, then a traditional A/C unit may not help as much as you think. A/C tends to dry your air even more and can cause skin complaints as well as dehydration.

If you live in a desert, like me, you may want to try an evaporative cooler, often called a swamp cooler instead. A swamp cooler uses clean water to cool your room and increase humidity, helping you breathe easier at night. 

Staying cool with a window air conditioner

Now that you know your options, how will you choose? We think the Midea window air conditioner is the best option for most people. It cools 150-square feet and easily fits in the windows of offices, dorm rooms, or any upstairs room that needs supplemental cool air. The settings are controlled via the dials, so there’s no new system to learn to get it working. Overall, it’s a simple and efficient choice anyone can enjoy. 

If losing access to your window is a big downfall for you, then the Midea U inverter window air conditioner is a great alternative. The noise levels will reach a maximum of 42 dB, making it the quietest option on our list. Plus, the ability to pair it with your smart assistant or phone gives you options for conveniently adjusting the temperature on the fly.
