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.
