How to choose
Match BTU to room size
BTU states how much cooling a unit gives, and the coverage figure states the room size it fits. The Amazon Basics, GE and LG units give 5,000 BTU for rooms up to 150 sq ft, while the Frigidaire and Midea units give 6,000 BTU for rooms up to 250 sq ft. Compare the coverage figure with your room's floor area before looking at controls or modes.
Controls and timers
Controls set temperature, fan speed and mode, and a timer sets when the unit runs. The Amazon Basics and GE use mechanical controls, while the Frigidaire and Midea use a remote. The Frigidaire has a 24-hour on/off timer. The Midea has Cool, Fan, and Dehumidifier modes with a 3-speed fan.
Noise and window fit
Noise is given in dB, and a lower figure means a quieter unit on its low setting. The LG runs as low as 50 dB and the Midea as low as 52 dB, while the Amazon Basics runs at 56 dB. Measure your window opening first: the Amazon Basics fits windows 23 to 36 inches wide with a minimum height of 13 inches.
