 Product Description

LONG DESCRIPTION  
The MRCOOL® DIY Hybrid 48,000 BTU Multi-Zone Heat Pump System is a powerful, flexible comfort solution designed for homeowners who want whole-home efficiency, zoning control, and true DIY installation—without sacrificing performance or appearance.
 
This professionally balanced hybrid system pairs the MRCOOL® DIY 5th Generation 48K Multi-Zone Condenser with a 36,000 BTU DIY Hybrid™ ducted air handler and a 9,000 BTU OuttaSight® one-way ceiling cassette, creating a clean, modern HVAC layout that blends central ducted comfort with targeted zone control.
 
The 36K ducted air handler delivers quiet, evenly distributed airflow through ductwork—ideal for large living spaces, basements, or whole floors—while the 9K ceiling cassette discreetly conditions bedrooms, offices, or bonus rooms without using wall space.
 
Thanks to MRCOOL® DIY QuickConnect® technology, installation is simplified using pre-charged R-454B refrigerant line sets, eliminating the need for vacuum pumps, gauges, or licensed refrigerant handling. The included DIYPRO® cable removes the need for electrical conduit, further reducing install time and cost.
 
Advanced DC inverter technology, Gold Fin® corrosion-resistant coils, and full MRCOOL® Smart HVAC Controller® integration ensure whisper-quiet operation, lower energy bills, and reliable year-round comfort—all controlled from your phone or smart home system.
