The definition of a split ductless air conditioning system is a type of air conditioning system that is used to cool a single room or multiple rooms within a building. Unlike traditional air conditioning systems, split ductless systems don’t require ductwork and are usually more energy efficient. Split ductless systems are also known as mini-split systems and are composed of two main components: an outdoor condenser and an indoor air handler. The outdoor condenser is responsible for cooling the air and the indoor air handler is responsible for distributing the cooled air throughout the room or rooms. The indoor air handler is connected to the outdoor condenser by a conduit that houses the refrigerant lines, power cable, and condensate drain. Split ductless systems are ideal for cooling single rooms or multiple rooms within a building and are a great alternative to traditional air conditioning systems.
