The MRCOOL® DIY® 5th Gen Multi-Zone 55,000 BTU Ductless Mini Split is built to provide reliable heating and cooling across three independently controlled zones. This configuration combines a 55,000 BTU outdoor condenser with 6,000 BTU, 12,000 BTU, and 36,000 BTU wall-mounted air handlers for flexible comfort across different areas of the home.
The three indoor units allow each zone to be managed independently, making it easier to maintain comfortable temperatures in rooms of different sizes. The 6,000 BTU unit is suited for smaller spaces, while the 12,000 BTU and 36,000 BTU air handlers provide greater capacity for larger areas.
Featuring 22 SEER2 efficiency, DC inverter technology, R-454B refrigerant, smartphone app controls, Follow Me® functionality, and pre-charged Quick Connect® technology, this system combines efficient performance with a convenient DIY-oriented installation design.
