Ducted Air Conditioning in Perth metropolitan
Ducted air conditioning runs a single indoor unit through a network of ducting hidden in the ceiling space, feeding conditioned air to each room through discreet outlets. Done well, it heats and cools an entire home evenly and disappears visually, with only outlets and a control panel or two visible. Done badly, it means airflow that never quite reaches the back bedrooms, a system too big or small for the house, or ductwork that leaks air into the roof space instead of the rooms below. We've listed 140 businesses in Perth that install, service and repair ducted systems, covering everything from new-build installs in Baldivis and Ellenbrook to retrofits in older brick-and-tile homes across the western suburbs.
Before choosing a contractor, get a proper room-by-room heat load calculation rather than a rough quote based on house size alone. Ask how they'll zone the system (living areas and bedrooms usually need separate zones so you're not cooling empty rooms), which brand and capacity they're proposing, and whether the quote includes ceiling access, electrical work and a WA-compliant warranty on both parts and labour. Get at least two or three quotes, since duct design and installation quality vary more than the brand of unit does.

Common questions about ducted air conditioning
- How much does ducted air conditioning cost to install in Perth?
- For an average three or four bedroom home, expect a wide range depending on house size, roof access and system capacity. Smaller, simpler homes with easy roof access sit at the lower end, while larger homes needing multiple zones, extra ducting runs or difficult ceiling access cost more. Always get an itemised quote so you can see what's covered: unit, ducting, zoning, electrical, and any make-good work to the ceiling.
- How often does a ducted system need servicing?
- Most manufacturers and installers recommend a filter clean every few months during heavy use and a professional service once a year, ideally before summer. Regular servicing catches refrigerant leaks, dirty coils and duct issues early, which is cheaper than a breakdown call-out in the middle of a 40 degree week.
- What should I expect on installation day?
- A typical residential install takes one to three days depending on the number of zones and any ceiling or electrical complications. Expect roof space access, some cutting for outlets and returns, running of refrigerant and electrical lines to an outdoor unit, and commissioning and testing of each zone before handover.
- How can I tell if a ducted air conditioning contractor does good work?
- Look for a proper heat load calculation rather than a quick guess, clear explanation of zoning, correctly sized ducting (undersized ducting is a common cause of weak airflow), and a written warranty covering both the equipment and their labour. Reviews mentioning tidy ceiling work and follow-up service are a good sign.
