>What Is Ductless Air Conditioning?
Unlike the typical ‘split’ central air conditioning system, comprised of an outdoor compressor/condenser unit and indoor evaporator/air handling unit for distributing cooled air through ductwork in your home’s attic or crawlspace, ductless or ‘mini-split’ systems are different. Ductless systems are installed directly into the wall of your home, the noisy, compressor/condenser parts of the system located in a unit on the outside wall (or up to 50-feet away), connected to indoor system components installed on floors, walls or ceilings via small tubing. It is from these interior wall-mounted units that cooled air is directly distributed.

Ductless systems operate via a control panel located on the interior wall-mounted unit. Some have remote controls. The interior components of these smaller systems work similarly to those in ducted, heat-pump-style, split HVAC systems (hence the name ‘mini-split’) – but they need no bulky ductwork, relying instead on interior wall-mounted units to distribute air. Up to 8 indoor room units can work with a single exterior compressor/condenser unit. These units connect to interior wall-mounted units via refrigerant lines, which require only a few small, 3-inch holes for the delivery of cooled air. Fans in the interior unit distribute air, taking in warm air through the top, and emitting cooled air out of vents in the bottom.
