Product Description 

Model: DIYM436HPW01D122

The MRCOOL® DIYM436HPW01D122 is a premium 4-zone ductless mini-split system engineered for homeowners who want true room-by-room comfort, higher efficiency, and a professional-grade system they can install themselves.

This configuration pairs the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser with three 6,000 BTU air handlers and one 9,000 BTU air handler, making it an ideal solution for bedrooms, offices, nurseries, guest rooms, or mixed-use spaces where loads vary slightly from room to room.

What sets this bundle apart is the inclusion of 25-ft DIY® QuickConnect® line sets for every zone, giving installers added flexibility for longer runs without sacrificing performance or warranty coverage. Each line set arrives factory-sealed and pre-charged with R-454B refrigerant, eliminating vacuum pumps, gauges, and refrigerant handling.

Paired with DIYPRO® cable, Gold Fin® corrosion protection, and full MRCOOL® Smart HVAC Controller® support, this system delivers quiet operation, lower energy costs, and long-term reliability—without contractor labor.
