In Focus｜MRCOOL® DIY® Hybrid 48,000 BTU Multi-Zone Heat Pump System (18K Wall Mount + 24K Ducted Air Handler) – 21.8 SEER2 – Model DIYM448HPHY1824

Product Description 
The MRCOOL® DIY Hybrid 48,000 BTU Multi-Zone Heat Pump System is a powerful, flexible HVAC solution designed for homeowners who want central-ducted comfort AND ductless zoning—without paying for professional installation.
 
This hybrid system is powered by the MRCOOL® DIY® 5th Generation 48K multi-zone condenser and pairs an 18,000 BTU wall-mounted air handler with a 24,000 BTU ducted DIY Hybrid™ air handler. This combination is ideal for homes that need open-room ductless control alongside hidden, ducted comfort for bedrooms, hallways, or larger shared spaces.
 
Thanks to MRCOOL®’s patented DIY® QuickConnect® technology, installation requires no vacuum pumps, gauges, or licensed HVAC contractor. The system arrives pre-charged with R-454B refrigerant, offering improved efficiency and lower environmental impact compared to older refrigerants.
 
With DC inverter technology, quiet operation, and full smart-home compatibility, this hybrid system delivers precise temperature control, lower energy bills, and true DIY convenience—making it one of the most versatile HVAC solutions MRCOOL has ever released.
