Product Description
Model: DIYM236HPW07D01
The High-Power Dual-Zone MRCOOL System Built for Large Rooms — With Perfect Line-Set Flexibility
The MRCOOL DIYM236HPW07D01 is the ideal multi-zone system for homeowners who need serious heating and cooling power in two large rooms — but with different distances to the outdoor unit. This bundle includes two 18,000 BTU air handlers plus two Quick-Connect line sets (16 ft + 25 ft), giving you the flexibility to install each indoor unit exactly where you want it.
This is one of the strongest 2-zone DIY bundles MRCOOL makes, delivering premium performance, ultra-quiet operation, and true do-it-yourself installation without vacuum pumps or refrigerant handling.
Why This Bundle Is the Perfect Fit for Large Spaces

Each indoor unit covers up to ~800 sq ft, making this setup perfect for:
Oversized master bedrooms
Great rooms
Living rooms
Workshops
Finished basements
Home offices
Garages or ADUs
This depends on your insulation, windows, ceiling height.
