12,000 BTU Mini Splits

Shop 12,000 BTU (plus 11,500 BTU) mini splits at Home Outlet Direct. Depending on the brand, a 12,000 BTU system covers roughly 500 to 750 sq ft, which suits large bedrooms and dens.

The BTU rating is the unit's total heating and cooling capacity, and these are mostly single-zone systems: one outdoor unit paired with one indoor head for one room. Between sizes? Round up. A slightly larger unit runs efficiently at partial load, while an undersized one runs constantly.

This collection includes systems from MRCOOL, Pioneer, Senville, and Daikin. Compare single-zone mini splits, design your own system with the Mini Split Bundle Builder, and add the right mini split line sets for your install.
