Product Description 

Model: DIYM436HPW00D122

The MRCOOL® DIYM436HPW00D122 is a high-efficiency 4-zone ductless mini-split system engineered for homeowners who want precise comfort control in multiple rooms without the cost, complexity, or delays of professional HVAC installation.

This bundle pairs the MRCOOL® DIY® 5th Generation 36,000 BTU multi-zone condenser with four 6,000 BTU wall-mounted air handlers, making it an ideal solution for bedrooms, offices, bonus rooms, finished basements, or home additions where balanced comfort matters.

What sets this system apart is MRCOOL®’s patented DIY® QuickConnect® technology. Each 25-ft pre-charged line set arrives factory-sealed with R-454B refrigerant, eliminating vacuum pumps, gauges, and refrigerant handling.
