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. Combined with the DIYPRO® cable, installation is faster, cleaner, and dramatically more affordable than traditional multi-zone systems.
With 23 SEER2 efficiency, DC inverter performance, and full MRCOOL® Smart HVAC Controller® support, this system delivers lower operating costs, whisper-quiet operation, and smart control from anywhere — exactly what today’s homeowners expect.
