1. Midea 8,000 BTU U-Shaped Smart Inverter Window Air Conditioner
Midea
Best overall for a small bedroom. What earns it a place here: inverter compressor settles into a low steady hum instead of cycling on and off through the night and u-shaped design lets you lock the window sash down over the unit for bedroom security. One caveat, installation is more involved than a standard slide-in unit since the frame splits around the sash.
