Product Description 

Model: DIYM336HPW01D00

The MRCOOL® DIYM336HPW01D00 is a powerful, high-efficiency 3-zone ductless mini-split system engineered for homeowners who need true room-by-room control, dependable year-round performance, and a DIY-friendly installation process—without sacrificing professional-grade quality.

This system is built around the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser, paired with two 6,000 BTU indoor air handlers for smaller rooms and one 18,000 BTU indoor air handler for a larger living space. This configuration is ideal for bedrooms, home offices, guest rooms, dens, and main living areas, allowing each zone to operate independently for maximum comfort and efficiency. 

Installation is simplified using MRCOOL®’s patented DIY® QuickConnect® technology. The included three 16-ft pre-charged QuickConnect® line sets arrive factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, gauges, or licensed refrigerant handling. Combined with the DIYPRO® cable, which removes the need for electrical conduit, this system delivers one of the fastest and cleanest multi-zone DIY installs on the market.

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