The MRCOOL® DIY® 5th Gen Multi-Zone 36,000 BTU Ductless Mini Split is built to provide independent heating and cooling across three separate areas. This configuration combines 6,000 BTU, 12,000 BTU, and 18,000 BTU wall-mounted air handlers with a single 36,000 BTU outdoor condenser.
The three indoor units allow the system to match different comfort requirements throughout the home, making it suitable for smaller bedrooms, offices, living spaces, additions, and larger rooms. The 6,000 BTU unit covers up to approximately 200 square feet, the 12,000 BTU unit up to approximately 550 square feet, and the 18,000 BTU unit up to approximately 800 square feet.
With a 23 SEER2 rating, DC inverter technology, R-454B refrigerant, smartphone app controls, Follow Me® functionality, and MRCOOL's pre-charged Quick Connect® technology, this multi-zone heat pump combines efficient operation with a simplified DIY installation approach.
