The Vario Series 45000 BTU 3-zone mini split system is designed for powerful multi-room heating and cooling with a high-capacity 12K + 24K + 24K indoor unit configuration. This tri-zone mini split AC includes three indoor air handlers with separate controllers and one outdoor condenser, allowing each room to be adjusted independently for personalized climate control. Designed to cover up to 3550 sq. ft., with one indoor unit recommended for up to 550 sq. ft. and two indoor units recommended for up to 1500 sq. ft. each, this ductless mini split AC with heat pump is ideal for pairing a medium-sized bedroom, office, or guest room with two large living areas, open spaces, or primary suites. Built with DC inverter technology, it helps reduce power consumption by up to 30% while delivering dependable heating performance down to -13℉ and cooling operation in outdoor temperatures as low as 5℉. The system uses R454B refrigerant and includes convenient comfort features such as 4D airflow, 24-hour timer, Sleep Mode, Eco Energy Saving Mode, multiple fan speeds, heating, cooling, and dry mode for dehumidifying. Operating as low as 52 dBA, this mini split provides steady airflow for spacious multi-room layouts.
Please Note:
Designed for situations where zones don’t run at full capacity simultaneously. If total indoor demand exceeds the outdoor unit, the system still works but may deliver slower cooling or heating. For continuous high demand, consider a larger or multi-system setup.
