Mini Splits for 1,000–1,500 Sq. Ft.

For one large connected space from 1,001 to 1,500 sq. ft., start with a 24,000 BTU mini split. Ceiling height, insulation, direct sun, windows, and local climate can change the final fit. Homes and work areas with closed rooms need separate indoor units, so compare voltage, heating performance, SEER2, and installation requirements before choosing a multi-zone plan.
