💰 Ways to save
- Treat any '$12 a duct' Facebook ad as a hook — the real money comes from a high-pressure upsell to 'urgent' mould or sanitising treatment once they're on site. Consumer Affairs Victoria has warned about exactly this on community pages.
- Ask for before-and-after photos taken inside the actual ducts as proof of work; and don't book duct cleaning at all for a wall-mounted split system — it has no ducts to clean.
How we estimate this
Duct cleaning for a standard home in 2026 runs about $200–$500, and it scales with the number of outlets: six vents or fewer is roughly $200–$300, seven to ten vents $300–$400, and eleven-plus $400–$600. Per vent the going rate is around $25–$50 ($25–$40 in Melbourne). Sanitising and deodorising are extra, and genuine mould remediation adds $150–$300 on top.

What a duct cleaning costs in Perth
Perth's dry Mediterranean climate changes the picture: many homes use evaporative cooling, whose ducting is a different system from refrigerated ducted air, and the dry air means mould in the ducts is far less of an issue than in the humid cities. Where ducted refrigerated systems exist, cleaning clears built-up dust and the fine sand and grit that is the real local culprit, as it blows in and settles through a system in Perth's gritty, free-draining environment.
The double-brick construction common here affects how ducts were run in the first place, often through the roof space, and that access is where a clean's time goes. Labour sits a touch below the national average, keeping the rate reasonable, and isolation adds little to a service like this beyond parts. For a Perth duct clean, the dry climate makes dust and sand, rather than mould, the thing being cleared, which keeps the job comparatively straightforward.

Frequently asked questions
How much does duct cleaning cost?
About $200–$500 in 2026 for a typical home — roughly $25–$50 per vent — with six-vent homes around $200–$300 and eleven-plus around $400–$600. Sanitising and mould treatment add more.
How often should ducts actually be cleaned?
For a normal dry home the evidence for routine cleaning is weak. It's genuinely worthwhile when there's visible mould, vermin, post-renovation debris or flood damage — not on a fixed annual schedule.
How do I avoid a duct-cleaning scam?
Be wary of dollar-a-duct ads, brand-new Facebook accounts, stock photos and on-the-spot 'urgent mould' upsells. Ask for before-and-after photos taken inside your own ducts, and never book duct cleaning for a ductless split system.
