What Is Ducted Air Conditioning & How Does it Work?

Ducted air conditioning, also known as central air conditioning gives you quiet, even, or zoned cooling or heating that works well in the summer or winter. But how does ducted air conditioning work?

Ducted air conditioning uses a central unit to cool or heat the air and then send it through a system of air conditioning ducts to all the rooms in a house or building. Ducted air conditioning can send cooled air to every room in a home, or it can be set up so that different rooms have different temperatures.

Exactly How Does Ducted Air Conditioning Work?

Ducted air conditioners can cool, heat, and remove moisture from the air in your home or building. This gives you control over the temperature and humidity all year long with the touch of a finger. Let’s look at how ducted air conditioning works in more depth.


Like split system air conditioning, ducted air conditioning uses refrigerants to cool or heat the air in your home so you can control the temperature. As the refrigerant changes from a liquid to a gas and back again, its temperature changes, which changes the temperature of the air around it. This “conditions” the air to make it either cool or warm.

An evaporator inside the indoor unit of your ducted air conditioning system pulls warm air from your home when you want to cool it. The refrigerant stored in the evaporator is a cold liquid. When warm air passes over it, it cools the air, which is then sent through the ducts of your home’s air conditioner.

As the coolant takes in heat, it changes into a gas. The refrigerant is turned back into a liquid by the outdoor unit’s compressor. The liquid refrigerant then flows through a condenser. Before going back to the evaporator, the liquid goes through depressurisation and cooling.


With reverse-cycle ducted air conditioning, you can flip a switch to make your home or building cool in the opposite direction. The process can be a little more complicated, but the same rules apply as with cooling but in the opposite direction.

Other Elements

In addition to the parts that make the air conditioning work, ducted air conditioning systems can have a number of other useful parts and technologies. Filters can be added to your system to help get rid of allergens like dust and other nasty pollutants that may be in the air. Your system’s sensor and controller can help you make more detailed decisions about how to change the temperature in your home, how the air conditioner is divided into zones, how the timers are set, and how to do other things that can be controlled centrally or even by smart devices.

How Does Air Conditioning With Zones Work?

The way your air conditioning ducts are set up can create different zones in your home. For example, a home’s kitchen, bedroom, and living room can all be in different zones, depending on how it’s set up. Zoning lets people more carefully control how different parts of their home are heated or cooled. This saves money on energy because less energy is wasted.

Ducted Air Conditioning vs Split System Units

Both split systems and ducted air conditioners have reverse cycle technology that allows them to cool and heat. The main differences between them are how they look and how much more it costs to install ducted air conditioning.
