A ductless split unit is a type of air conditioning system that is becoming increasingly popular in homes and businesses. It is an efficient and cost-effective way to cool or heat a space without the need for extensive ductwork. The unit is composed of two parts: an outdoor compressor and an indoor air handler. The compressor is responsible for circulating refrigerant to the indoor air handler, which then circulates the cooled or heated air into the room. The indoor air handler can be mounted on the wall or ceiling, and the outdoor compressor can be installed on the side of the building or in the yard. The two components are connected by a conduit that carries the refrigerant and electrical wiring. The ductless split unit is ideal for areas where ductwork is not possible or desirable, such as additions, sunrooms, and attics. It is also an excellent choice for zoned heating and cooling, as it allows for independent temperature control in each room.
