Ductless systems deliver cooling and/or heating to specific, targeted areas within the home. The installation is less invasive and can even be less expensive since these systems don’t require ductwork to distribute air. Ductless systems have an outdoor unit connected through a small hole to a compact wall-mounted unit indoors. Each indoor unit is designed to provide warm or cool air solely for the room in which it is installed. The indoor unit can be installed on a wall, in the ceiling, or on the floor. Ductless systems can be used for only one or two rooms, but they can also be expanded to make up to 8 separate climate zones in your home.
