What Is a Ductless Mini-Split System?
As its name implies, a ductless mini-split system is a heating and cooling technology that does not use ductwork to distribute air throughout a home or business. It has two main components: an outside unit and multiple inside units. The outside unit houses the compressor and is connected to the inside unit(s) via a small conduit that contains refrigerant lines, power cables, and a condensate drain.
When turned on, the outside unit compresses the refrigerant, which cools or heats the air depending on the selected mode. Then, the outdoor unit sends air through a conduit to the indoor air handlers. Ductless mini-split systems can be an excellent choice for homes or businesses that do not have ductwork or need to supplement existing HVAC units.
