The 4MXX8 indoor multi-split heating and cooling unit works as part of a ductless multi-split system. This ductless product can be mounted near the floor or ceiling and offers high-efficiency heating and cooling for precise comfort with no ductwork.

Ductless System

Composed of three main components—an indoor unit consisting of a coil and a fan, an outdoor compressor unit, and a remote control—most ductless multi-split heating and cooling systems are connected by refrigerant lines and require no ductwork. The indoor multi-split heating and cooling unit can be mounted on the wall or in the ceiling.

Efficient Comfort

Trane’s ductless multi-split heating and cooling units have Seasonal Energy Efficiency Ratings (SEER) ranging from 16.00 to 22.00, making the systems remarkably efficient and environmentally friendly.

Quiet Operation

Specially designed air vents efficiently reduce sound to provide quiet comfort as low as 29 dB, for whisper-quiet operation.

Design Flexibility

Since there is no ductwork to install, it’s easy to add Trane’s reliable heating and cooling to any home, in any room desired. It’s an economical and efficient option for homes without an existing ducted system or when adding ductwork may be impractical or too expensive.
