MRCOOL® DIY® 5th Gen Multi-Zone 4-Zone 36,000 BTU 23 SEER2 (6K + 6K + 6K + 6K)- 4x 16ft line sets-Ductless Mini-Split Air Conditioner & Heat Pump — DIYM436HPW00D00

Product Description 
Model: DIYM436HPW00D00
The MRCOOL® DIYM436HPW00D00 is a perfectly balanced 4-zone ductless mini-split system designed for homes that need even comfort across multiple small rooms—such as bedrooms, offices, guest rooms, or additions—while still delivering high efficiency and true DIY installation.
This system pairs the MRCOOL® DIY® 36,000 BTU 5th Generation multi-zone condenser with four 6,000 BTU wall-mounted air handlers, allowing each room to maintain its own temperature independently. It’s an ideal solution for homeowners who want consistent comfort without oversizing individual spaces.
Installation is where this system truly separates itself from competitors. MRCOOL®’s patented DIY® QuickConnect® pre-charged line sets arrive sealed with R-454B refrigerant, eliminating vacuum pumps, gauges, and refrigerant handling. Combined with the DIYPRO® cable, installation is cleaner, faster, and far more affordable than traditional multi-zone systems.
With 23 SEER2 efficiency, DC inverter technology, and full MRCOOL® Smart HVAC Controller® integration, this system delivers quiet operation, lower energy bills, and total control from anywhere—exactly what modern homeowners expect.
