How Does Ductless Air Conditioning Work?

Updated: Feb 9, 2023

Ductless air conditioning is both an energy and cost-efficient way to add air conditioning to older homes or home with additions that lack ductwork. Having to factor in the cost of renovating a home to install ductwork makes installing central air conditioning impractical for many homeowners. However, due to the design of the equipment used for ductless air conditioning, there is only minimal disruption to a home’s existing structure during installation. Learn more about ductless air conditioning and how it works here.

Main Components of a Ductless Air Conditioning System

A ductless air conditioning system is made up of two components: the compressor unit and the unit containing the fan. The compressor unit, which is the larger of the two components, is installed outdoors near the home on a concrete slab. The second component is conveniently installed on an exterior wall in the area to be cooled.

The two components are connected by copper refrigerant lines that run through holes that have been drilled in the wall. The room where the fan unit is installed does not require additional wiring because electricity will be supplied from the outdoor unit, which will be holed up to an electrical source.

How Does a Ductless Air Conditioner Work?

A ductless air conditioning system works similar to how a central air conditioning system works but without a series of intricate ductwork.

When the unit is turned on, the outdoor compressor will pump and cool the refrigerant within the system’s refrigerant lines. The cooled refrigerant is sent to the indoor fan unit where the cooled air is then dispersed into the room. Being that cooled air is heavier than warm air, the cooled air will drop while the warm air will rise. The energy and moisture from the warm air are then absorbed into the system by the fan component and transferred via the refrigerant lines back out to the compressor for the heat transfer process to begin again.

Advantages of Cooling with a Ductless System

Installing a ductless air conditioning system in your home can allow you to set up zoned cooling in your home. This can help you save money on your electric bill by cooling only certain areas when needed. The system uses less electricity and produces less noise than other cooling options. A ductless system can also help to control humidity and reduce other indoor air quality concerns.
