💰 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 Adelaide
Adelaide's lower labour rates make duct cleaning one of the more affordable of the capitals, and the dry Mediterranean climate helps: mould in the ductwork is far less of an issue than in the humid eastern cities, so the job is mostly about clearing built-up dust and debris from the ducts, vents and return air. Evaporative cooling is common here too, whose ducting is a separate system from refrigerated ducted air.
Ducted reverse-cycle and ducted heating are used where winter warmth matters, and these accumulate the dust a clean targets over a season of running. The accessible single-storey housing stock makes roof-space duct access straightforward in many homes. For an Adelaide duct clean, the cheaper labour and the dry climate combine to keep it a steady, affordable job, with the system's size and the roof access the main things that set the hours rather than any mould problem.

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.
