Product Description 

Model: DIYM427HPW01D88

The MRCOOL® DIYM427HPW01D88 is a highly efficient 4-zone ductless mini-split system designed for homeowners who want precise room-by-room comfort, lower energy costs, and a true DIY installation without compromising reliability or performance.

This bundle pairs the MRCOOL® DIY® 27,000 BTU 5th Generation multi-zone condenser with three 6,000 BTU indoor air handlers and one 9,000 BTU indoor air handler, making it an excellent solution for homes with multiple bedrooms, offices, or mixed-size spaces that need balanced airflow and independent temperature control.

What sets this system apart is MRCOOL®’s patented DIY® QuickConnect® pre-charged line sets, which arrive factory-sealed with R-454B refrigerant. This eliminates vacuuming, gauges, and refrigerant handling, allowing installation without HVAC licensing. Combined with the DIYPRO® cable, installation is cleaner, faster, and far more cost-effective than traditional systems.

With 23 SEER2 efficiency, DC inverter technology, and full MRCOOL® Smart HVAC Controller® support, this system delivers quiet operation, smart scheduling, and long-term energy savings—perfect for homeowners who want comfort they can control from anywhere.
