The 41,000 BTU dual zone concealed duct mini split system with a 22,000 + 22,000 BTU configuration is designed for high-capacity climate control, delivering powerful and independent comfort across two large zones. It supports coverage up to 1,600 sq. ft., making it well-suited for spacious homes, open-concept layouts, and light commercial environments that require strong and consistent airflow distribution.
Powered by a 20 SEER2 inverter compressor, the system intelligently adjusts output to maintain stable indoor temperatures while improving energy efficiency under heavy demand. The concealed duct design allows installation within ceilings or attic spaces, preserving a clean architectural appearance while maintaining quiet operation as low as 34 dB.
Built for year-round performance, the heat pump provides reliable heating and cooling even in temperatures down to -13°F. Smart features include WiFi control via the DELLA App, Alexa compatibility, thermostat and remote operation, and geolocation automation. Additional functions such as dehumidification, smart defrost, and self-cleaning enhance everyday usability.
