Ducted Air Conditioning in Perth: Whole-Home Comfort

Ducted air conditioning cools your whole Perth home from one central system, delivering even comfort through discreet ceiling vents. Ducted air conditioning is a bigger investment than a split, but it treats the house as a whole. Here is how it works and what installation involves.

How ducted air conditioning works
Ducted air conditioning uses a central unit, usually in the roof space, connected to ducts that run to vents in each room. The system pushes conditioned air through these ducts, cooling or heating the whole home evenly. Because the unit and ducts are hidden, all you see are neat vents in the ceiling.

6 things to know about ducted air conditioning

  • It cools the whole home, not one room
  • Zoning lets you control areas separately
  • It needs roof or ceiling space for ducts
  • It is easiest in a new build or big reno
  • The electrical supply must suit the system
  • Installation involves refrigeration and electrical work

Zoning and control
A big advantage of ducted air conditioning is zoning, dividing the home into areas you can control separately. You can cool the living areas by day and the bedrooms at night, rather than the whole house at once. Zoning makes ducted more efficient and is a key part of getting the running costs down.

What installation involves
Installing ducted air conditioning is a significant job: the central unit, the ductwork through the roof, the vents, the controller, and the electrical supply. It is most straightforward in a new build or major renovation, when the ducts can be run before ceilings are closed. An installer plans it around your home.

Roof space and layout
Ducted air conditioning needs room in the roof for the unit and ducts, so the home’s layout and roof space matter. Most Perth homes can accommodate it, but it is something an installer checks early. Where roof space is tight, the design is adjusted to suit, or a split system may make more sense.

The electrical side
A ducted system draws more power than a split, so the electrical supply, circuit and sometimes switchboard capacity must suit it, occasionally needing three-phase for larger systems. The electrical work is part of the install, which is why ducted air conditioning is a job for licensed refrigeration and electrical trades together.

Is it right for your home?
Ducted air conditioning suits homes that want whole-home comfort and have the roof space and budget for it. If you only use a couple of rooms, splits may be more economical. Weighing how you use your home helps decide whether ducted or a split system is the better fit.

Reverse cycle for winter
Most ducted systems are reverse cycle, so they heat as well as cool. That makes them a whole-home solution for both a Perth summer and the cooler months, from one system. It is worth factoring this year-round use into the decision, since it adds value beyond summer cooling.

Running costs and efficiency
A ducted system cooling the whole home uses more power than a single split, but zoning and a well-sized, efficient unit keep the running costs sensible. Cooling only the zones you are using, rather than the whole house, is the key to running it economically over summer.

Why use a licensed installer
Ducted air conditioning installation spans refrigeration and electrical work and must be done correctly. A licensed installer designs, installs and certifies the system, including the electrical supply. The state’s Building and Energy sets the electrical standards involved.
