Key Takeaways
- Split systems need filter checks every 1-3 months and a professional deep clean on a regular schedule.
- Ducted systems are harder to self-maintain and generally need an annual professional clean of the full duct network.
- Ducted systems affect air quality in every connected zone, so neglect compounds across the whole house.
- Pricing differs between the two — split systems are priced per unit, ducted is a single package.
Split systems and ducted air conditioning aren’t just different in how they’re installed — they need genuinely different cleaning approaches and schedules. Here’s what Sydney homeowners should know before booking a service.
How Does Cleaning Differ Between the Two Systems?
Split systems have individual indoor units, each with its own filter that should be checked every 1 to 3 months, plus periodic professional servicing of both the indoor and outdoor components. Ducted systems are far harder to self-maintain — the duct network runs through your ceiling or floor and isn’t something you can inspect or clean yourself. Professional cleaning of the full network is generally recommended annually.
What Are the Health and Air Quality Considerations?
With a ducted system, one dirty duct network affects air quality in every connected zone of the house — it’s not isolated to a single room the way a split system issue would be. That means neglect compounds faster and affects more of your home, which is part of why regular ducted cleaning matters even though it’s less visible day to day.
How Do Costs Compare?
Split systems are priced per indoor unit, while ducted cleaning is a single package covering the whole network. See our aircon cleaning cost in Sydney guide for the full pricing breakdown.
Which One Do You Have?
If you have one or more wall-mounted units with a matching outdoor unit, that’s a split system. If your home is cooled and heated through vents in the ceiling or floor with no visible indoor unit, that’s a ducted system. Not sure which signs to look for on your split system specifically?
