Designed to combine powerful climate control with effortless DIY installation, this system lets you provide your clients with tailored comfort that fits any space.

Envision Tailored Multi-Zone Comfort

Imagine offering your clients the luxury of personalized temperature control across multiple rooms without the hassle of bulky ductwork. This system features two sleek ceiling cassette air handlers — a 9,000 BTU unit ideal for spaces between 180 and 375 square feet, and a 12,000 BTU unit designed for rooms from 376 to 500 square feet. Both fit neatly between standard 16” ceiling joists, delivering a clean, modern look that complements any home, garage, or commercial space.

Installation Made Effortless and Efficient

MRCOOL’s patented Pre-Charged Quick Connect Line Sets, included in 25 and 50-foot lengths, come pre-filled with R-410A refrigerant, enabling you to install quickly and confidently without vacuum pumps or specialized equipment. This streamlined installation saves time and labor costs, allowing you to complete more projects with less hassle.
