Ducted Air Conditioning in Perth metropolitan
Ducted air conditioning runs a single system through a network of hidden ductwork in your roof space, feeding conditioned air into every room through ceiling vents. It's the option most Perth homeowners look at when they want whole-house comfort without a wall unit in every room. The category covers straight installs on new builds, retrofits into existing homes (which usually means more work in the roof and sometimes bulkheads to hide duct runs), and the ongoing servicing that keeps a system running efficiently through Perth's long, hot summers. We've listed 217 businesses across the metro area that install and maintain these systems, from single-operator outfits to larger firms running multiple crews.
Because the ductwork and the indoor unit sit above your ceiling, a lot of what determines whether a system performs well for the next 15-20 years is hidden from view once the job's done. That makes the contractor's design work and installation standard more important than almost anything else in this category. Look for a business that does a proper room-by-room heat load calculation rather than a rough guess based on floor area, that explains duct sizing and zoning options clearly, and that's upfront about brand choice, warranty terms and who handles callbacks if something's wrong. Ask how they insulate and seal duct joins, since poor sealing is a common source of energy loss and uneven cooling.

Common questions about ducted air conditioning
- How much does ducted air conditioning cost to install in Perth?
- For an average 3-4 bedroom home, budget roughly $8,000 to $16,000 depending on system capacity, number of zones and how much duct and bulkhead work is needed. Larger homes, multi-zone setups or difficult roof access push costs higher. Get at least three itemised quotes since pricing varies a lot between installers for the same brand and capacity.
- How often does a ducted system need servicing?
- Most manufacturers and installers recommend a service once a year, ideally before summer, covering filter cleaning, checking refrigerant levels, inspecting ductwork for leaks and testing the outdoor unit. Homes near the coast or in dusty areas may need filters cleaned more often between full services.
- What should I expect during a ducted air conditioning installation?
- Expect an initial site inspection and heat load assessment, then one to three days of installation work involving roof access, running ductwork to ceiling vents, mounting the outdoor condenser and connecting electrical and control wiring. There's some ceiling access needed and minor patching may follow if new vents are cut in.
- How do I judge whether an installer did a good job?
- Even airflow across every room, no obvious temperature difference between zones, a quiet indoor unit, and ductwork that's properly insulated and sealed at joins are the practical signs. Ask to see the heat load calculation they used and confirm in writing what's covered under both the manufacturer's warranty and the installer's workmanship warranty.
