What is Ducted Air Conditioning?

Air conditioning is literally part of the furniture in Aussie homes.

We bl**dy need it.

Ducted air conditioning is a practical, whole-house cooling and heating solution.

That kicks the at-times unbearable Aussie climate right in the arse.

They’re a great addition to any home, but have you ever wondered how these little beauties work? 

Let’s have a squiz.

How Does Ducted Air Conditioning Work? 

Most of us are familiar with split systems—where the internal unit sits on the wall, inside your home. And a noisy unit sits outside.

What’s the diff between ducted air conditioning vs split systems? Have a Captain Cook at our blog.

With ducted systems, the internal unit is tucked inside the roof cavity of your home, with a noisy unit sitting outside. A refrigeration cycle cools or warms the air and delivers it via a series of ducts and vents into each room.

How does ducted air conditioning work? Here’s a simplified breakdown of the process in cooling mode:

how ducted air conditioning works?

The Evaporator

A blower siphons warm air from inside your home and funnels it to evaporator coils within the indoor unit. 

These coils contain low-temperature, low-pressure refrigerant. The refrigerant absorbs the heat from the warm air and turns it into a high-pressure gas.  

As the warm air blows over the evaporator coils, it cools and then distributes it throughout your home via vents.


The high-pressure refrigerant gas moves onto the compressor in the outdoor unit. There, the gas is pressurised and condensed into a liquid.


The liquid refrigerant flows through to the condenser’s coils. Then, the heat is pushed out into the ambient environment by fan-forced operation.  

Next, the refrigerant is then fed back to the indoor unit and absorbs heat from the living environment.

And so, the cycle repeats.

What are Zones in a Ducted Air Conditioning System?

A ducted air conditioning system can reach different areas of your home—also known as zones. 

Zoning helps reduce running costs and maintain comfy temps year-round. 

So, you can keep your living room at the ideal telly watching temp during blazing summers. And, at the same time, you can set the optimum climate for sleeping littlies.

MyAir is an advanced, Aussie-made air-conditioning control product. You can adjust the temperature and airflow in up to 10 rooms. Using the MyAir App, control the climate in individual rooms via smartphone, tablet, or voice-activated device.

So, crank up the AC remotely before you leave the office. Or turn it off from your phone if you forgot when you left the house.
