MRCOOL® 48K 6-Zone DIY® Mini Split Bundle with 6K + 36K Wall Units & Two 16ft Line Sets - R-454B — 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.
