What is this guide about?
Ducted air conditioning is a popular way to cool and heat a whole home on the Gold Coast, and it is a large part of our work. This guide explains how ducted systems work, their benefits, how to choose the right one, what good installation and maintenance look like, and how to run one efficiently. Whether you are building, renovating or replacing an old system, it is a practical starting point.
How does ducted air conditioning work?
A ducted system has an outdoor unit and an indoor fan coil unit, usually hidden in the roof space. Air is drawn back through a return grille, filtered, cooled or heated, and delivered through insulated ducts to ceiling outlets in each room. A zone controller opens and closes motorised dampers so you choose which rooms get air.
Unlike split systems, which cool one room each, a ducted system serves the whole house from one central unit. The parts that matter most are the capacity of the units, the size and layout of the ducts, the number and position of outlets, and the controller. Understanding these helps you compare quotes and make good decisions about installation, maintenance and use.
What are the benefits of ducted air conditioning?
Ducted air conditioning gives whole-home comfort with even temperatures, zoning to control which rooms you cool, quiet operation in living spaces, nothing on the walls, and filtration of the air you breathe. Zoning keeps running costs in check by cooling only the rooms in use.
- Even comfort: every room on the system can reach a comfortable temperature, without hot and cold spots.
- Zoning: cool bedrooms at night and living areas by day. With AirTouch 5, each zone can hold its own temperature.
- Air quality: all air passes through the return-air filter; a filter and UV sanitiser can be added.
- Quiet: the indoor unit is in the roof, so you hear only gentle airflow at the outlets.
- Discreet design: only slim outlets and a return grille are visible.
How do you choose the right ducted system?
Start with a room-by-room heat load assessment that considers the size and layout of the home, insulation, windows and orientation, and how you use each space. That sets the capacity, the zones, and the size of each duct and outlet. Then choose a brand and controller that fit your budget.
We visit, measure and design the system to the house, rather than picking a size off a chart. We supply systems from Mitsubishi Heavy Industries, Daikin, Samsung, Hisense, Fujitsu, Mitsubishi Electric, Panasonic. Our guide comparing Daikin, Fujitsu, Samsung and Mitsubishi covers the differences, and our ducted packages show common set-ups. You can also start a design online.
What are the best practices for installation and maintenance?
Good installation means a proper design, well-supported and sealed ducts with good insulation, a correctly placed and secured outdoor unit, a dedicated electrical circuit, careful commissioning and a tidy finish. Good maintenance means an annual service and regular filter checks.
Our in-house technicians and electricians handle the whole job, so there is no hand-over between trades. We commission the system, show you how to use the controller, and clean up before we leave. Read the full installation process, step by step.
After installation, schedule a service every year and check the return-air filter every few months. Our maintenance service keeps the system efficient and reliable. Every ducted install comes with:
- 10-year workmanship guarantee: Covers the gas (refrigerant) charge and call-outs.
- 10-year duct and pipework warranty: On the ductwork and pipework we install.
- 5-year parts and labour on units: Indoor and outdoor units. Hisense units carry 5+2 years.
- 5-year zonetouch controller warranty: On the ZoneTouch zone controller.
Warranties apply once the job is paid in full. See our warranty.
How do you make a ducted system sustainable and energy efficient?
Choose an efficient inverter system sized to the home, insulate and seal the ducts well, use zoning and schedules so you only cool occupied rooms, set 25–27°C for cooling, and keep it serviced. If you have solar, run cooling while the panels are producing.
Modern ducted systems use inverter compressors and lower-impact R32 refrigerant in most new models. Smart controls make efficient habits easy. Read about refrigerants, smart controls and solar and batteries.
