Product Description 

Model: DIYM448HPW01D00

The MRCOOL® DIYM448HPW01D00 is a powerful 4-zone ductless mini-split system designed for homeowners who want true room-by-room comfort, professional-grade efficiency, and the ability to install their system without paying contractor labor.

This configuration combines the MRCOOL® DIY® 5th Generation 48,000 BTU multi-zone condenser with three 6,000 BTU wall-mounted air handlers—ideal for bedrooms, offices, or smaller spaces—plus one 24,000 BTU air handler to deliver higher output for a large living area, open floor plan, or master suite.

Installation is simplified using MRCOOL® DIY® QuickConnect® line sets, which arrive factory-sealed and pre-charged with R-454B refrigerant, eliminating the need for vacuum pumps, gauges, or licensed HVAC labor. The included DIYPRO® cable removes the need for electrical conduit, reducing install time and complexity.

With DC inverter technology and an impressive 21.8 SEER2 efficiency rating, this system provides quiet operation, lower energy costs, and long-term reliability—making it an ideal upgrade from older HVAC systems or inefficient mini-splits.
