Product Description 

Model: DIYM336HPW02D37

The MRCOOL® DIYM336HPW02D37 is a high-efficiency 3-zone ductless mini-split system designed for homeowners who want professional-grade performance with the freedom of true DIY installation. Built around the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser, this system delivers powerful, reliable heating and cooling while dramatically reducing installation cost and complexity.

This configuration pairs two 6,000 BTU wall-mounted air handlers—perfect for bedrooms, offices, or small living spaces—with one 24,000 BTU air handler designed for larger areas such as open-concept living rooms, garages, basements, or bonus rooms. Each zone operates independently, allowing precise temperature control while maximizing energy efficiency.

Installation is streamlined using MRCOOL® DIY® QuickConnect® technology. The included 25-ft pre-charged QuickConnect® line sets arrive factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, gauges, or licensed HVAC labor. The included DIYPRO® cable removes the need for electrical conduit, further reducing installation time.

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, lower utility bills, and long-term reliability, making it one of the most complete DIY multi-zone systems on the market today.
