What does aircon cleaning cost in Sydney, and what drives the price?
A split system deep clean costs $249 + GST for the first indoor unit, $199 + GST for the second and $189 + GST for each unit after that (five or more units are quoted). A ducted system is $349 + GST for the return air package. If you prefer to keep your current filter, our Deep Scrub & Sanitise option is $229 + GST: the duct foils deep-scrubbed through to the return duct, a professional sanitise, and an airflow check and test run. The ducted price covers a new filter, the aluminium duct foils cleaned from the filter through to the return duct, a professional sanitise, and an airflow check and test run. Most Sydney homes pay just that. Every visit includes a free full home inspection, and if your room ducts also need cleaning, your technician quotes on the spot and you approve before any work starts. High-rise access, rooftop condensers and strata approvals add time. The figures below are our own, from jobs we actually run across Sydney — no Australian government or industry body publishes cleaning prices, so treat any “official” rate you see elsewhere with suspicion.
Key Takeaways
- A split system deep clean starts from $249 + GST for the first indoor unit, with each additional unit priced lower.
- Ducted system cleaning is $349 + GST, covering a new filter, the aluminium duct foils from the filter through to the return duct, and a professional sanitise.
- Deep cleaning (not filter-only cleaning) is what actually removes mould, bacteria and dust buildup from inside the unit.
- Unit count, system type and accessibility all affect the final price.
Aircon cleaning pricing depends heavily on what kind of system you have and how many units need attention. Here’s a clear breakdown of what Sydney homeowners typically pay in 2026.
What’s the Typical Sydney Pricing by Service Type?
These are our standard rates for a full deep clean — not a filter-only wipe-down, which isn’t a service we offer since it doesn’t actually address the buildup inside the unit.
| Service | Price |
|---|---|
| Split system deep clean — 1st indoor unit | $249 + GST |
| Split system deep clean — 2nd unit | $199 + GST |
| Split system deep clean — 3rd unit | $189 + GST |
| Split system deep clean — 4th+ unit | $189 + GST each |
| 5+ units | Custom quote |
| Exhaust fan cleaning | $50 – $100 + GST (depending on outlet type) |
| Ducted system package (new filter, duct foils to the return duct, professional sanitise, airflow check and test run) | $349 + GST |
What Affects the Price?
- Number of units — pricing steps down per unit, so multi-unit homes get better value per split system.
- System type — split systems are priced per unit, while ducted systems are a $349 + GST return air package.
- Accessibility — units in hard-to-reach locations can add to the job.
- Level of buildup — a unit that hasn’t been cleaned in years may need more thorough attention.
What’s the Difference Between a Regular Service and a Deep Clean?
A “service” often just means a filter check or a quick external wipe-down — it doesn’t touch what’s actually inside the unit. A genuine deep clean opens up the accessible internal components and treats the coil, fan barrel and drainage area where mould, bacteria and dust actually accumulate. This is why filter-only cleaning isn’t something we offer as a standalone service — it doesn’t address the buildup that affects air quality and airflow.
Why Does Split System vs Ducted Cleaning Cost Differ?
Split systems are priced per indoor unit because each one is cleaned individually. Ducted systems are priced as one return air package because the system shares a single airstream, so the new filter, the duct foils through to the return duct and the sanitise are done as one job.

How Often Should You Budget For It?
Regular cleaning keeps both cost and air quality predictable. See how often to clean your air conditioner for a full frequency guide based on usage.

Where these prices come from: they are our own, based on jobs we actually run across Sydney. No Australian government or industry body publishes aircon cleaning prices, so any page presenting an “official” rate is not quoting one. What is published is the cost of not cleaning — an Australian Government factsheet on cleaning coils reports a dirty evaporator coil cutting cooling capacity by 7 per cent while raising power draw by 16 per cent.
