The 48,000 BTU number is the total system capacity of the outdoor unit. With a single-zone system it can cool one large space. With a multi-zone system it can be split across several rooms, where each indoor head is sized for its own 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, Daikin, Senville, TURBRO, and Pioneer. 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.
