Powerful Three-Zone Climate Control for Every Space
This system comes equipped with three versatile air handlers designed to cover a range of room sizes for maximum flexibility. Two 12,000 BTU units cover medium-sized rooms between 376 and 500 square feet—ideal for bedrooms, offices, or living areas. One larger 18,000 BTU air handler handles bigger spaces from 501 to 750 square feet, perfect for open-plan rooms, workshops, or commercial areas. Each air handler offers multiple modes — COOL, HEAT, AUTO, DRY, and SLEEP — to deliver personalized comfort no matter the season.
Effortless Installation with Pre-Charged Quick Connect Line Sets
What truly sets this system apart is MRCOOL’s patented Pre-Charged Quick Connect Line Sets. These copper line sets come pre-filled with R-410A refrigerant, eliminating the need for vacuum pumps or refrigerant charging. The included 25-foot install kit provides ample length for most installations, and quick connect fittings make setup fast and simple. Need extra reach? The optional coupler kit lets you extend line sets easily, providing unmatched installation flexibility.
