Summary
Bring flexible, concealed comfort to your space with the new 5-Zone R454B Slim-Duct Mini Split System by Cooper & Hunter. A 48,000 BTU condenser powers slim-profile duct units that disappear into ceilings or soffits while delivering whisper-quiet performance down to -13 F. Slim-Duct air handlers use TU1 copper tubing, medium/high static pressure blowers, built-in Wi-Fi smart kits, and R454B refrigerant for reduced GWP without sacrificing efficiency (up to 24 SEER2).
