MRCOOL® DIY® MRCOOL DIY 5th Gen 48,000 BTU Hybrid Mini Split System (36K Ducted + 6K Wall) – 21.8 SEER2 – Model DIYM48K-HYB-36D-6W

 Product Description 

The MRCOOL® DIYM48K-HYB-36D-6W Hybrid Mini Split System is a powerful, high-efficiency heating and cooling solution engineered for homeowners who want maximum flexibility, zoning control, and professional-grade performance—without paying for professional installation.

 

This hybrid system combines a 48,000 BTU MRCOOL® DIY® 5th Generation multi-zone condenser, a 36,000 BTU ducted DIY Hybrid™ air handler, and a 6,000 BTU wall-mounted air handler, allowing you to heat and cool large open areas with ductwork while maintaining precise, independent comfort control in smaller rooms.

 

Designed for whole-home comfort, renovations, additions, garages, basements, and mixed-layout homes, this system gives you the best of both ducted and ductless HVAC in one integrated platform.

 

Installation is simplified using MRCOOL®’s patented DIY® QuickConnect® technology, eliminating the need for vacuum pumps, refrigerant charging, or HVAC licensing. All line sets are pre-charged with eco-friendly R-454B refrigerant, and the included DIYPRO® cable removes the need for electrical conduit.

 

With DC inverter technology, Gold Fin® corrosion protection, and full smart home integration, this system delivers whisper-quiet operation, lower energy bills, and reliable year-round comfort.
