The MRCOOL® DIY® 5th Gen Multi-Zone 36,000 BTU Ductless Mini Split provides independent heating and cooling for three separate rooms through a single outdoor condenser. This configuration combines two 9,000 BTU wall-mounted air handlers with one 12,000 BTU air handler for flexible, room-by-room comfort.
The two 9,000 BTU indoor units can condition spaces of up to approximately 400 square feet each, while the 12,000 BTU air handler is designed for areas up to approximately 550 square feet. This makes the system suitable for bedrooms, offices, living spaces, additions, and other areas requiring individually controlled comfort.
With a 23 SEER2 rating, DC inverter technology, R-454B refrigerant, Wi-Fi and smartphone app compatibility, Follow Me® functionality, and MRCOOL's DIY installation design, this multi-zone heat pump delivers efficient year-round comfort with convenient control from virtually anywhere.
