Midea U-Shaped 10,000 BTU
#1 in WindowFull review
A quiet, efficient pick for bedrooms and living rooms up to 450 sq ft. The U shape lets you keep using the window and keeps the compressor noise outside.

4.2/5
A good-value smart inverter unit for a bedroom or office up to about 350 sq ft. It’s quieter and cheaper to run than TCL’s fixed-speed models for little extra money.

A solid inverter pick for a bedroom up to 350 sq ft if you value the two-year warranty. Otherwise the TCL Q-Series does the same job for less.
