Melbourne runs ducted heating and cooling hard, so its systems accumulate the dust that duct cleaning targets.

💰 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 Melbourne
Melbourne has one of the highest rates of ducted systems in the country, because ducted heating runs through the long, cold winters and ducted reverse-cycle does double duty for the summer, so the ductwork sees heavy year-round use and accumulates dust, debris and allergens that a duct clean clears. The city's deep trade pool keeps the job competitive, and the extent of the system and the roof or sub-floor access are the main cost variables.
Older ducted gas heating in period and post-war homes, often with ducts under the floor or in the roof, is a staple of the Melbourne market, and these older systems are frequent candidates for a clean. The cold winters mean households spend a lot of time with the system running and the house closed up, which is a common prompt to clear the ducts of accumulated dust. For a Melbourne duct clean, the system's size and age and the access are what set the hours.

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.
