💰 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 Brisbane
In Brisbane, ducted reverse-cycle cooling runs through a long, humid season, and the subtropical humidity is the defining duct-cleaning factor: cool, damp ducts are an ideal place for mould to establish, so clearing and treating mould, not just dust, is often the real reason a household books the job. A system that runs cool against humid air can circulate musty odours and spores if the ductwork is not kept clean.
Brisbane labour sits around the national baseline, cheaper than Sydney, with a good supply of installers who do this work. Timber Queenslanders and elevated homes can make roof-space and under-floor duct access either easier or more awkward depending on the build. The storm season adds debris and moisture that can find its way into a system. For a Brisbane duct clean, the humidity-driven mould risk is what makes the job worth doing regularly, alongside the ordinary dust.

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.
