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 

✔ Two Powerful 18K Air Handlers

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.

 

✔ Mixed Line Set Lengths = Maximum Freedom

You get:

• (1) 16ft – DIY16-1412-O
• (1) 25ft – DIY25-1412-O

So you can place each indoor unit at the correct distance — no extra coils, no messy loops, and no performance loss.

Every component is factory pre-charged with R-454B, the new low-GWP refrigerant.

Just tighten the Quick-Connect fittings — no special tools required.
