The MRCOOL® DIY® 5th Gen Multi-Zone 48,000 BTU Ductless Mini-Split Heat Pump System provides efficient heating and cooling for two separate spaces with two 12,000 BTU wall-mounted air handlers. With 21.8 SEER2 efficiency, DC inverter technology, and R-454B refrigerant, this system delivers flexible comfort while maintaining efficient operation throughout the year.
Designed for straightforward DIY installation, the system uses MRCOOL® pre-charged Quick Connect® line sets, allowing qualifying installations to avoid the traditional evacuation and refrigerant-charging process. Each 12,000 BTU air handler can cover up to approximately 550 square feet and provides independent temperature control, while built-in Wi-Fi and Smart HVAC app compatibility make it easy to manage comfort from a compatible smartphone.
The system features Follow Me®, low ambient cooling, Gold Fin® condenser protection, quiet mode, washable filters, and compatibility with Amazon Alexa and Google Home. The 48,000 BTU condenser operates on 208/230V single-phase power and is backed by a 5-year parts warranty and 7-year compressor warranty, with limited lifetime replacement coverage available through the MRCOOL® Care Program.
