Key Takeaways
- A split system deep clean starts from $249 for the first indoor unit, with each additional unit priced lower.
- Ducted system cleaning is a package deal from $349, covering foils, ducts and filter replacement.
- 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 โ 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 โ 1st indoor unit | $249 |
| Split system deep clean โ 2nd unit | $199 |
| Split system deep clean โ 3rd unit | $189 |
| Split system deep clean โ 4th+ unit | $189 each |
| 5+ units | Custom quote |
| Exhaust fan cleaning | $50 โ $100 (depending on outlet type) |
| Ducted system package (foils, ducts, filter replacement, full sanitization) | $349 |
What Affects the Price?
- Number of units โ pricing steps down per unit, so multi-unit homes get better value per split system.
- System type โ split systems are priced per unit, while ducted systems are a single package covering the whole network.
- Accessibility โ units in hard-to-reach locations can add to the job.
- Level of buildup โ 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 โ 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 โ 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 a package because the whole network โ foils, ducts and filters โ is treated as one connected 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.
