Trane’s residential lineup includes gas furnaces, air conditioners, heat pumps, air handlers, ductless systems, and packaged equipment. Select XV models use TruComfort variable-speed technology to adjust their output in small increments, helping maintain steadier temperatures and humidity levels than conventional single-stage equipment. Trane also uses proprietary components like Climatuff compressors and Spine Fin coils in many outdoor units. Compatible systems can connect through Trane Link controls and the UX360 smart thermostat for coordinated operation, remote access, and system diagnostics.
