Cooper&Hunter 4-Zone Ducted Mini Split AC & Heat Pump 36000 BTU (6K+6K+9K+9K), Slim Duct Units, 230V
Bring flexible, concealed comfort to your space with the Cooper & Hunter Slim-Duct system. A 36000 BTU condenser powers slim-profile duct air handlers that disappear into ceilings, soffits, or chases for a clean, unobtrusive finish. This inverter heat pump provides independent control in 4 zone(s) and supports low-ambient heating performance down to -13 F.
Slim-Duct air handlers use TU1 copper tubing, medium / high static pressure blower performance, built-in Smart Kit connectivity, and R454B refrigerant (low-GWP) for efficient operation up to 24 SEER2. Equipped models include a refrigerant sensor to help maintain optimal operation.
Key features
Concealed comfort + ducted flexibility
