Mini-split systems direct heating or cooling to one room or small area of your home. They make sense for homes or parts of homes that don’t have an existing duct system.
A ductless system has two parts: an outdoor compressor unit and one (or more) indoor units. The two units are connected by a refrigerant line threaded through holes drilled behind the indoor units.
Electricity from the outdoor unit powers a fan in the indoor unit, sending cooled air into an area. At the same time, warm air is removed from the space and sent to the outdoor unit.
