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 indoor unit can be mounted on the wall or in the ceiling.

Efficient Comfort

Trane’s ductless 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 26db, 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 indoor units feature:

Quiet Operation

Specially designed air vent efficiently reduces operation noise to provide quiet comfort, as low as 29 dB.

Flexible Installation Options

Flexible installation options to meet different requirements.(Floor/Ceiling units only).

Compact Design

The compact construction and simple structure make the console and floor/ceiling models easy to install and maintain.

Washable Filter

To reduce moisture on filter and provide fresh, healthy air into the room, clean filter regularly with water.

Anti-Cold Feature

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.

Wired Controller

Floor/Ceiling Indoor units ship with a wired controller displaying temperature, operational mode, and time settings.
