The MRCOOL® DIY® 5th Gen Multi-Zone 55,000 BTU Ductless Mini Split is built to deliver customized heating and cooling across three separate indoor zones. This configuration pairs two 9,000 BTU wall-mounted air handlers with one 18,000 BTU air handler, making it suitable for homes that require different comfort levels across multiple rooms.
With two compact 9,000 BTU units designed for spaces up to approximately 400 square feet each and an 18,000 BTU unit capable of covering up to approximately 800 square feet, this system provides flexible room-by-room comfort. Each indoor unit can be controlled independently for more precise temperature management throughout the home.
The 22 SEER2 system combines DC inverter technology, R-454B refrigerant, Wi-Fi connectivity, smartphone controls, Follow Me® functionality, and MRCOOL's Quick Connect® technology. The pre-charged connection system simplifies installation by eliminating the need for specialized evacuation and charging equipment.
