Product Description 

Model: DIYM336HPW01D37

The MRCOOL® DIYM336HPW01D37 is a high-efficiency 3-zone ductless mini-split system designed for homeowners who want true room-by-room comfort control, lower energy costs, and a professional-grade system that can be installed without hiring an HVAC contractor.

This bundle is powered by the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser, paired with two 6,000 BTU indoor air handlers for smaller spaces and one 18,000 BTU indoor air handler for larger living areas. The layout is ideal for bedrooms, home offices, guest rooms, bonus rooms, and main living spaces, delivering independent temperature control in every zone.

Installation is made dramatically easier thanks to MRCOOL® DIY® QuickConnect® technology. The included three 25-ft pre-charged QuickConnect® line sets arrive factory-sealed with R-454B refrigerant, eliminating vacuum pumps, gauges, and EPA handling. Combined with the DIYPRO® cable, which removes the need for electrical conduit, this system is one of the most DIY-friendly multi-zone HVAC solutions available today.

With DC inverter technology, Gold Fin® corrosion-resistant coils, Follow Me® temperature sensing, and full MRCOOL® Smart HVAC Controller® App integration, this system delivers quiet operation, precise comfort, and long-term durability—all backed by industry-leading warranties.
