Product Description 
Model: DIYM427HPW00D88
 
The MRCOOL® DIYM427HPW00D88 is a perfectly configured 4-zone ductless mini-split system designed for homeowners who want maximum control, ultra-quiet comfort, and true DIY installation without cutting corners. This bundle pairs the proven MRCOOL® DIY® 27K BTU 5th Generation multi-zone condenser with four 6,000 BTU wall-mounted air handlers, making it ideal for bedrooms, offices, nurseries, guest rooms, and smaller living spaces.
Each zone operates independently, allowing you to fine-tune temperatures room by room while reducing wasted energy. Installation is streamlined using DIY® QuickConnect® pre-charged line sets, which arrive factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, gauges, or HVAC certification. Combined with DIYPRO® cable, this system avoids conduit requirements and significantly reduces installation time and cost.
With DC inverter technology, 23 SEER2 efficiency, and full MRCOOL® Smart HVAC Controller® integration, this system delivers quiet, efficient, and reliable comfort year-round—while keeping operating costs low and control fully in your hands.
