Description
The Comfort-Aire MCT018AGC30C0PS is an MC Compact Series single-stage water-source heat pump built for commercial spaces that need efficient, repeatable heating and cooling without oversized equipment footprints. This style of unit is a strong fit for offices, medical suites, classrooms, multifamily corridors, retail buildouts, and other commercial zones that are served by a water loop (or similar hydronic source) and need dependable, controllable comfort at the zone level.
MC Compact Series units are designed around efficiency and service practicality. The platform uses low-GWP R-454B refrigerant, exceeds ASHRAE 90.1 efficiency standards, and pairs a coaxial heat exchanger with a TXV metering device for stable operation across common commercial load conditions. Noise control is addressed with sound-absorbing insulation and double-isolation compressor mounting, which matters in occupied spaces.
Controls are built for faster commissioning and troubleshooting. The unit family includes microprocessor controls with on-board fuse and emergency shutdown, a performance-monitoring system (Unit Performance Sentinel), and multiple standard safety features. A front-left external connecting port supports service tool connectivity to reduce startup and service time, and CXM2 communicating controls support real-time operating condition visibility.
