Energy Bill Concerns

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.

• High speed operation quickly reaches desired temperature.
• Sleep Mode Function
• Operate the unit automatically only when you want by setting the timer
• Auto Clean and Triple Filtration
• To prevent blowing cold air directly to the room, air is pre-heated during heating operation

The 38 Series Ductless heat pump system has the capability to provide comfort in most any space found in residential homes. With an inordinate operating range, this highly efficient system scoffs at extreme cold and hot temperatures. This system has a small outdoor unit footprint while the indoor unit can be mounted on most any wall. Additionally, American Standard offers a handheld remote control and traditional wall mounted digital controls for the system.
