Mini Splits for Up to 500 Sq. Ft.

For one connected room up to about 400 sq. ft., a 9,000 BTU mini split is the usual starting path; for most connected rooms from 401 to 500 sq. ft., start with 12,000 BTU. Sun, insulation, ceiling height, windows, and equipment heat can change the final fit. Separate rooms need their own indoor-unit path, so compare individual single-zone systems or multi-zone configurations, then verify voltage, heating performance, SEER2, and installation requirements before ordering.
