Product Description 

Model: DIYM336HPW03D00

The MRCOOL® DIYM336HPW03D00 is a high-efficiency 3-zone ductless mini-split system engineered for homeowners who want room-by-room comfort, lower energy costs, and a true DIY installation—without sacrificing professional-grade performance.

This system is powered by the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser and paired with one 6,000 BTU air handler and two 9,000 BTU air handlers, making it ideal for bedrooms, offices, guest rooms, bonus rooms, and smaller living areas. Each zone operates independently, allowing precise temperature control while maximizing efficiency and comfort.

Installation is simplified using MRCOOL® DIY® QuickConnect® technology. The included 16-ft pre-charged QuickConnect® line sets arrive factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, refrigerant gauges, or licensed HVAC labor. The included DIYPRO® cable removes the need for electrical conduit, further reducing installation time and cost.

With DC inverter technology, Gold Fin® corrosion protection, Follow Me® temperature sensing, and full MRCOOL® Smart HVAC Controller® App integration, this system delivers quiet operation, long-term reliability, and smart energy savings—making it one of the strongest DIY multi-zone systems available today.
