The MRCOOL® DIY® 5th Gen Multi-Zone 55,000 BTU ductless mini split system combines three independently controlled zones with one 12,000 BTU and two 18,000 BTU wall-mounted air handlers. This configuration provides flexible comfort control for multiple rooms while allowing each zone to operate according to its individual needs.
The 55,000 BTU outdoor condenser delivers up to 47,000 BTU of cooling and 55,000 BTU of heating, with a 22 SEER2 efficiency rating. DC inverter technology continuously adjusts system output to match demand, while the heat pump design provides year-round heating and cooling from one outdoor unit.
Installation is simplified with MRCOOL's pre-charged Quick Connect® line sets. The system uses R-454B refrigerant and supports smartphone control through the Smart HVAC app, Follow Me® functionality, and compatible Amazon Alexa and Google Home voice control. Line sets are selected separately for each indoor air handler.
