Key takeaways
- Most air duct cleaning jobs in Australia land between A$100–A$1,200 — known locally as duct cleaning (ducted heating/cooling).
- No licence applies to duct cleaning in Australia. Ducted gas heating is widespread in Victoria, where periodic duct cleaning and CO-safety servicing of the furnace (by a licensed gasfitter — a separate trade) are both recommended.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Australia typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a air duct cleaning pro in Australia
- Confirm experience with your system type — ducted gas heating (Victoria especially), ducted refrigerated, or evaporative cooling
- Get vent count and price in writing
- Ask for negative-pressure or rotary-brush extraction with before/after photos
- Check for dead-vermin and dust removal experience — roof-cavity ducts collect both
- Confirm public liability insurance
- Consider a duct-sealing check at the same time; leaky flexible ducts waste energy
Red flags
- Ultra-cheap per-vent offers with on-site inflation
- No photo evidence of results
- Fogging upsells without confirmed mould
- No insurance or ABN

Frequently asked questions
Does duct cleaning improve air quality or health?
Evidence is mixed for routine cleaning of already-clean ducts. It clearly helps when ducts contain mould, construction dust, pest debris, or blockages. Pairing cleaning with better filtration and sealing duct leaks delivers more measurable benefit than cleaning alone.
What is the duct cleaning scam I should watch for?
The pattern: a $50-100 'whole house special', then on-site claims of hidden mould with photos that may not be from your ducts, pressure-selling sanitizer fogging at hundreds extra. Legitimate firms quote by vent/system count, show you findings in your own ducts, and never pressure same-day decisions.
What does professional duct cleaning actually involve?
Proper source-removal cleaning puts the system under negative pressure with a high-power vacuum, then agitates each duct run with rotating brushes or compressed-air whips so debris is pulled to the collector — not blown into the house. Register covers, the air handler, and coils should be included.
Why is dryer vent cleaning important?
Lint-clogged dryer vents are a leading cause of house fires and make dryers run long and hot. Annual cleaning of the vent run — not just the lint trap — restores airflow, cuts drying times, and removes the fire risk. It's cheap relative to the risk.
Should ducts be sanitized or fogged with biocide after cleaning?
Usually no — blanket chemical fogging is discouraged unless there's confirmed microbial growth and the product is approved for HVAC use. Mechanical cleaning plus fixing the moisture source addresses the cause; fogging is the most-upsold, least-needed add-on.
How often should ducts be cleaned?
There's no fixed schedule — clean when there's visible mould, vermin, renovation dust, or significant debris buildup. In practice every 3-5 years is typical for forced-air homes, sooner after building work or if filters blacken quickly.
How long does whole-house duct cleaning take?
A typical single-system home takes 2-4 hours with a two-person crew. Larger homes, multiple air handlers, or heavy contamination stretch to a full day. Be suspicious of anyone promising a whole house in under an hour.
Is duct cleaning worth it for Australian ducted heating?
Yes when ducts run through dusty roof or underfloor spaces — common in Victorian homes with ducted gas. Cleaning removes years of dust and occasional vermin debris; pair it with a licensed gasfitter's service of the heater itself for CO safety.
