An efficient, easy comfort option.

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 split systems are connected by refrigerant lines and require no ductwork. The ductless mini-split cooling unit can be mounted on the wall or in the ceiling.

Efficient Comfort

Trane’s ductless mini-split indoor 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 26 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.

Every Trane ductless system consists of an indoor and an outdoor unit. Trane mini-split ductless indoor units feature:

Quiet design

Specially designed air vents efficiently reduce operating sound to provide quiet comfort.

Turbo function

Provides temporary high-speed operation to reach your desired temperature quickly.

Sleep mode function

Based on a set sleeping time, the temperature can automatically rise or fall to maintain comfort in the room while you sleep, saving energy in the process.

Auto clean

The fan runs when the unit is stopped to prevent bacteria from forming. The unique catechin filter in each ductless mini-split unit is made from an additive abstracted from natural green tea to provide long-lasting sterilization and removal of up to 95percent of potentially harmful bacteria.

Anti-cold design

Air is pre-heated during heating operation to prevent blowing cold air directly to the room.


You set the time for the unit to operate automatically when you want.

Wireless remote control

Each indoor unit is controlled with a wireless remote control (purchased separately) so you can easily control your system from anywhere in the room. The "I feel" function enables the system to sense temperature at the remote control, rather than a thermostat.

Memory function

In case of power loss, the system will restart in the previous operation mode without the need to reset the system.
