Product Description 

Model: DIYM448HPW01D216

 

The MRCOOL® DIYM448HPW01D216 is a professionally engineered 4-zone ductless mini-split system designed for homeowners who need longer line-set reach, precise zoning, and industry-leading DIY installation technology.

This system pairs the MRCOOL® DIY® 5th Generation 48,000 BTU multi-zone condenser with three 6,000 BTU wall-mounted air handlers—perfect for bedrooms, offices, and smaller living spaces—plus one 24,000 BTU air handler engineered for high-load areas such as living rooms, open layouts, or large master suites.

Unlike standard bundles, this configuration includes 25-foot DIY® QuickConnect® line sets, allowing greater installation flexibility for homes where the outdoor condenser must be placed farther from indoor zones. Each line set arrives factory-sealed, pre-charged with R-454B refrigerant, eliminating vacuuming, refrigerant handling, or licensed HVAC labor.

Powered by DC inverter technology, protected by Gold Fin® corrosion-resistant coating, and controlled through the MRCOOL® Smart HVAC Controller®, this system delivers quiet operation, lower utility bills, and long-term reliability—all with true DIY simplicity.
