How to choose
Noise levels in decibels
Noise levels separate these units more than BTU alone. The Midea operates as low as 32 dB, the Windmill at 40 dB, the TCL at 54 dB, and the Amazon Basics at up to 56 dB. The LG operates as low as 53dB in low mode. Compare the decibel figure for each unit against the room where it will run, since a lower figure means less sound in that room.
Coverage and BTU together
BTU and coverage move together in this list, but coverage is the figure to match to your room. The Windmill and the Midea and the TCL each offer 10,000 BTU, while the LG offers 8,000 BTU and the Amazon Basics offers 5,000 BTU. Coverage runs to 450 sq ft for the Midea and the TCL, 350 sq ft for the LG, and 150 sq ft for the Amazon Basics. Match the coverage figure to your room size before choosing.
Controls and installation
Controls vary from basic to app-based in this list. The Windmill, the Midea, and the TCL offer app control with remote control, while the LG offers remote control and the Amazon Basics uses mechanical controls. Installation kits differ too: the Windmill includes a pre-assembled install kit, the Midea uses a quick-snap bracket, and the Amazon Basics includes an adjustable window kit with expandable side panels.
