How Does a Ductless AC Unit Work?

Ductless air conditioners have grown increasingly popular in recent years due to their efficiency and flexibility. These units are the perfect choice for home additions, garages and old homes that can’t accommodate ductwork, but you may be wondering how they work. Let’s talk about how a ductless mini-split AC works.

The Evaporator Unit

The evaporator unit, or blower, is the indoor part of a ductless AC. It sits on the wall, usually close to the ceiling, and houses the evaporator coils and fan. The coils hold refrigerant, which is what makes the whole system work.

The process begins when the refrigerant in the coils pulls heat from the air and the fan returns it to the room as cool, conditioned air. When the air is cooled, moisture condenses and returns to liquid form inside the evaporator unit, where it is separated from the conditioned air.

The Conduit

The conduit connects the indoor and outdoor units, holding the refrigerant tubing, power cable and condensate drain. One of the biggest advantages of a ductless AC is that it isn’t as invasive as other cooling options. Ductless AC installation only requires that a small hole be drilled in the exterior wall so that the conduit can connect the indoor and outdoor units.

The Condenser

The condenser is the outdoor unit of a ductless system. The refrigerant coils travel through the condenser, where the absorbed heat is released into the outside air. After the heat is released, the refrigerant travels back to the indoor unit and repeats the process of cooling.

How is this Different from Central Air Conditioning?

Surprisingly, the cooling process of a ductless AC is almost the exact same as a central air conditioner. The main difference between the two is that a single central air conditioner uses air ducts to disperse conditioned air throughout the house. Central ACs are usually placed in the attic or another storage space and use the ducts to reach the entire house, while a ductless AC cools a single room from that room.
