Mini-Split Wall-Hung Indoor Units
Wall-hung indoor units provide quiet, efficient heating and cooling with flexible room-by-room comfort and no conventional ductwork. They are one of the most popular indoor-unit styles for residential and light-commercial ductless mini-split systems.
Benefits of Wall-Hung Mini-Splits
Flexible ductless comfort without sacrificing floor space.
Quiet Indoor Operation
Modern wall-hung indoor units are designed for low sound levels, making them well suited for bedrooms, offices and living areas.
Heating & Cooling
When paired with a compatible heat-pump outdoor unit, wall-hung mini-splits can provide year-round heating and cooling.
Independent Zone Control
Each compatible indoor head can maintain its own temperature setting for room-by-room comfort.
Single-Zone Compatibility
Pair one wall-hung indoor unit with a compatible dedicated outdoor unit for a single room or area.
Multi-Zone Compatibility
Many wall-hung heads can be combined with compatible multi-zone outdoor systems for multiple independently controlled spaces.
No Traditional Ductwork
Wall-hung mini-splits deliver conditioned air directly into the space without conventional supply and return duct systems.
Residential & Commercial
Useful for homes, additions, offices, retail spaces, workshops and many other qualifying applications.
Designed for Flexible, Efficient Comfort
Wall-hung mini-split heads mount high on an interior wall and connect to a compatible outdoor condenser or heat-pump unit. Their compact design makes them useful where conventional ductwork is unavailable, impractical or unnecessary.
