Ducted Air Conditioning Installation & Replacement
Whole-home ducted systems — new installations, and replacement of ducted units that have reached the end of their life.
Ducted air conditioning cools the whole house from one system, with the fan coil in the roof space and outlets in each room. Done properly it is the most comfortable option there is. Done badly, you get rooms that never cool, ductwork that whistles, and a power bill nobody warned you about.
Most of the ducted work I do is changeovers — an existing system fifteen or twenty years old that has finally stopped. That is usually a good outcome for you, because the ductwork, outlets and roof penetrations are often reusable, and a modern inverter unit will cost meaningfully less to run than whatever is up there now.
Zoning is where a ducted system either earns its money or wastes it. Being able to shut down the bedrooms during the day and the living areas at night is the difference between running the whole house and running the part of it you are standing in. If the existing setup is one big zone, that is worth fixing at changeover time.
What's included
- New ducted installations — system sizing, duct layout and zoning design
- Ducted changeovers reusing serviceable ductwork where it is genuinely sound
- Zone control setup and smart controller integration
- Duct inspection — leaks, crushed flex and missing insulation are common and expensive
- Ducted gas heating installation
- Full commissioning, airflow balance and handover
Common questions
Can I keep my existing ductwork when I replace the unit?
Often yes, and it saves a lot. But it has to be inspected first — flex duct sags, gets crushed by anyone walking in the roof, and loses its insulation value over twenty years. I will tell you honestly what is reusable and what is not, because putting a new system on failed ductwork wastes the money you just spent.
How long does a ducted system last?
Fifteen to twenty years is typical for the unit itself with reasonable servicing. Ductwork can last longer if it was installed well and nobody has been walking on it.
Is ducted cheaper than multiple split systems?
Not up front — ducted is the bigger investment. It wins on whole-house comfort and on not having a head unit on every wall. If you only actually use two or three rooms, several splits may serve you better for less. I will say so if that is what your place calls for.
Do you add zoning to an existing ducted system?
Yes, where the duct layout allows it. It is much easier and cheaper to do at the same time as a changeover than as a standalone job later.
