The MRCOOL® DIY® 5th Gen Multi-Zone 55,000 BTU ductless mini split system provides heating and cooling for three separate zones using three 18,000 BTU wall-mounted air handlers. With a 22 SEER2 rating and DC inverter technology, the system is designed for efficient, flexible whole-home comfort.
The 55,000 BTU condenser delivers up to 47,000 BTU of cooling and 55,000 BTU of heating. Each indoor unit can operate independently, making it possible to maintain different comfort settings across multiple rooms while using a single outdoor condenser.
Installation is simplified with MRCOOL's pre-charged Quick Connect® line set system. The system uses R-454B refrigerant and includes smart controls, Follow Me® functionality, Wi-Fi connectivity, and compatibility with iOS and Android devices. Line sets are selected separately for each air handler.
