The Midea U-shaped air conditioner is EnergyStar certified, works with smart home devices, and runs quietly — in other words, everything you’d expect from the best energy-efficient air conditioner.

Midea U’s CEER rating (combined energy efficiency ratio) is 15. This rating measures the ratio of measured cooling capacity to measured average power consumption and measured off-mode power consumption.

Because the device has a U-shape, it is easy to install and allows you to open or close the window. What’s more, Midea U is the first window air conditioner to receive an EnergyStar “Most Efficient” rating in 2020, offering more than 35% energy savings compared to traditional air conditioners. And, of course, you’ll be comfortable and cool: you can feel the airflow up to 20 feet away, although some reviewers note that rooms don’t stay as cool as they’d like (normal for an energy-efficient machine).

Midea U Wi-Fi is easy to set up and you can control it from anywhere using Alexa, Google Assistant or the MSmartHome app (for iOS and Android). Easily remove and wash the filter when needed.

Who should try: People are looking for something quiet

Who should miss: People who are not used to installing household appliances on their own
