How Ductless Systems Work

Have you ever wondered how ductless HVAC systems deliver both heating and cooling with such efficiency? Understanding the mechanics behind these systems can help you appreciate their benefits even more.

A ductless HVAC system, often called a mini-split system, operates through two main components: an outdoor compressor/condenser and one or more indoor air-handling units. These components are connected by a conduit that houses the power cable, refrigerant tubing, suction tubing, and a condensate drain.

1. The Outdoor Unit: The process begins with the outdoor unit. This unit compresses and circulates refrigerant through the refrigerant lines to the indoor units. In cooling mode, the outdoor unit absorbs heat from the indoor air and releases it outside. In heating mode, the process reverses, extracting heat from the outdoor air (even at low temperatures) and transferring it inside.
2. The Indoor Unit: Indoor units are installed in the rooms or areas to be conditioned. Each unit contains an evaporator coil and a blower fan. The refrigerant from the outdoor unit flows into the indoor units, absorbing heat and cooling the air in the process. The blower fan then distributes the cooled or heated air directly into the room.
