MRCOOL® 48K 5th Gen 6-Zone DIY® Mini Split Bundle with (6K + 36K) Air Handlers with (16ft + 16ft) Pre-charged R-454B Line Sets- (230V), DIYM248HPW00D00

Product Description 
Model: DIYM248HPW00D00     
The Perfect Mixed-Room MRCOOL System — Small Bedroom + Huge Living Space Powered by a 48K 6-Zone Condenser
The MRCOOL DIYM248HPW00D00 bundle is engineered for homeowners who need precise zone control in both small and large rooms. This system combines a compact 6,000 BTU air handler—ideal for bedrooms, offices, or laundry rooms—with a powerful 36,000 BTU air handler that can condition large open areas like living rooms, workshops, basements, and great rooms.
Driven by the new 48,000 BTU 5th Generation DIY Multi-Zone Condenser, this package provides unmatched flexibility, premium heating and cooling performance, and true DIY installation with factory-charged R-454B Quick-Connect line sets.
This is one of the most advanced multi-zone heat pump systems MRCOOL has ever produced — and one of the few capable of managing up to 6 total zones, giving homeowners the freedom to expand later.
