Air-conditioning
Ducted air-conditioning in Brisbane
Ducted air-conditioning puts a single system in the roof space and distributes air through outlets in each room. It is the tidiest option visually, because there is no indoor head on any wall, and with zoning it lets you cool the parts of the house you are actually using.

- Fully insured
It is also the option that most rewards good design. Duct layout, outlet positions and zone grouping determine whether the far bedroom keeps up with the living room, and those decisions are made before installation rather than adjusted afterwards.
What it covers
What's included.
Whole-home assessment
Room by room load, not a single figure for the house, so each outlet is sized for the room it serves.
Zoning design
Rooms grouped into zones that reflect how the house is actually used through the day and night.
Duct layout
Runs planned through the roof space for the shortest sensible path and balanced airflow.
Outlet positioning
Outlet placement worked out against room layout, ceiling type and where the air needs to reach.
Indoor and outdoor units
Fan coil sited in the roof space with service access, condenser positioned for airflow and noise.
Controls and commissioning
Controller set up, zones balanced, system commissioned and explained on handover.
Why people call
Common reasons for this job.
- Cooling is wanted throughout the house rather than room by room
- Wall-mounted heads are not wanted in living areas or bedrooms
- A new build or major renovation is being planned
- Several split systems would be needed to cover the house
- Different parts of the house are used at different times
- An existing ducted system is old or no longer keeping up
How Hoff works
The approach.
The assessment is done room by room. A whole-house figure hides the fact that the west facing living room and the shaded rear bedroom have very different requirements, and that difference is what outlet sizing exists to handle.
Zoning is designed around how you live. Bedrooms on one zone and living areas on another is the common starting point, because it matches the way most households actually use the house through a day.
Roof space access and structure decide what is genuinely achievable. Hoff will tell you honestly where a duct run is difficult or where a particular outlet position is not practical, rather than promising a layout that cannot be built.
Refrigerant work requires ARCtick authorisation (Hoff holds L169731) and the electrical side requires an electrical contractor licence (90673). Both are covered by the same person. Electrical work is tested and certified on completion, and equipment carries its manufacturer warranty.
Suitable for
Where this comes up.
Ducted questions.
Neither is better in the abstract. Ducted suits whole-home cooling and leaves no indoor units on the walls. Splits suit one or two rooms and cost less to install. The right answer depends on the house and how many rooms you actually need to cool.
It lets you send air only to the parts of the house in use, so you are not cooling empty bedrooms all evening. It is the main reason a well designed ducted system can be economical to run.
That is one of the first things assessed. Roof height, access and structure determine what is possible, and Hoff will tell you if ducted is not practical for your building.
Often yes, if there is adequate roof space and access. It is more involved than a new build install, and the assessment will make clear what is required.
It depends on the size of the system and the building. You will get an expected duration with the quote.
