How to choose
Match BTU to room size
Cooling capacity in BTU sets how much cooling a unit gives, and the maker coverage figure tells you the room size it is rated for. The Midea is rated for up to 700 sq ft by the maker at 14,000 BTU, while the Frigidaire is rated for up to 450 sq ft by the maker at 10,000 BTU. Compare both figures together, since BTU alone does not tell you the room size.
Weigh noise and controls
Noise in dB tells you how loud a unit runs, and lower figures suit rooms where quiet matters. The Midea is rated at 41 dB and the LG at 59 dB, so the gap between them is worth checking before you buy. Controls matter too: the Midea adds app control and voice control, while the Frigidaire and LG use a remote.
Check fit and upkeep
Measure your window opening before you buy, since window units need a matching opening width and height. The Midea and Frigidaire fit openings from 23 to 36 inches wide, and the LG fits openings up to 23.63 inches wide. For upkeep, washable filters keep airflow steady: the Midea, Frigidaire and LG all have washable filters, and the Frigidaire and LG add filter alerts.
