Trane, a brand of Ingersoll Rand, introduced the TruComfort™ line of variable-speed air conditioners and heat pumps, which are designed to deliver precise and consistent comfort by running their compressors at the exact speed needed to keep homes comfortable. Featuring ComfortLink™ II Communicating Control Boards with refrigerant-cooled inverters, they consistently optimize their run speed, often at lower outputs, to provide continuous comfort within a half degree of the targeted temperature.
