MRCOOL® DIY® 5th Gen Multi-Zone 4-Zone 48,000 BTU 21.8 SEER2 (6K + 6K + 6K + 24K)- 4x 25ft line sets-Ductless Mini-Split Air Conditioner & Heat Pump- DIYM448HPW01D216

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.
