Powered by a 48,000 BTU condenser, this system supports four zones with a combination of ceiling cassette air handlers sized at 9,000 BTU and 12,000 BTU. The 9,000 BTU units cover smaller rooms (180-375 sq. ft.), while the 12,000 BTU units efficiently heat or cool medium-sized spaces (376-500 sq. ft.). Designed to fit seamlessly between standard 16” ceiling joists, these low-profile units provide discreet, ductless comfort with whisper-quiet operation.

MRCOOL’s patented Pre-Charged Quick Connect Line Sets make installation fast, clean, and tool-free. Pre-filled with R-410A refrigerant, these line sets eliminate the need for vacuum pumps or professional refrigerant charging. The included 35-foot install kit offers flexibility in unit placement, enabling you to complete projects faster and reduce labor expenses without compromising quality.

The Gold Fin® coated condenser resists corrosion and wear, extending system life — especially in harsh or coastal environments. With an impressive 20.5 SEER2 and 8.5 HSPF-5 rating, this system delivers energy-efficient cooling and heating that reduces utility bills. It also performs reliably in cold weather, providing warmth even when outdoor temperatures drop to 5°F.

Take full command of your multi-zone system with the SmartHVAC app. Easily adjust settings, switch modes, and manage each zone remotely from your smartphone or tablet, providing ultimate convenience for busy professionals and end users.
