Picture providing your clients with tailor-made climate control that’s as simple to install as it is to use.

Precision Comfort for Every Space

This system features two ceiling cassette air handlers — a 9,000 BTU unit for cozy spaces between 180 and 375 square feet, and a 12,000 BTU unit built for rooms from 376 to 500 square feet. Both fit neatly between standard 16” ceiling joists, offering a sleek, unobtrusive profile that complements any interior. With multi-zone compatibility through the DIY 4th gen MZ system, you can create customized comfort zones that eliminate the need for costly ductwork, giving your clients exactly what they need — no more, no less.

Installation That Saves You Time and Money

The MRCOOL patented Pre-Charged Quick Connect Line Sets (available in 35 and 50-foot lengths) revolutionize installation. Pre-filled with R-410A refrigerant, these line sets allow you to bypass vacuum pumps, special tools, and technician fees. This means faster job completion, lower labor costs, and higher profitability on every project. The system’s DIY-friendly design empowers you to confidently tackle installations that once required specialized expertise.
