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 heating and cooling 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

American Standard's ductless heating and cooling systems have Seasonal Energy Efficiency Ratings (SEER) ranging from 16.00 to 22.00, making the systems remarkably efficient and environmentally friendly.

Design Flexibility

Since there is no ductwork to install, it’s easy to add American Standard’s ductless heating and cooling units 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.

Zone Control

With a multi-split system, between two and five indoor units—depending on the indoor model—can be connected to just one outdoor unit, providing the exact degree of comfort you require room to room or zone by zone.
