Split System Service Sydney

A proper split system service — not just a filter rinse.

Split systems are simple machines, which makes it easy to assume they need nothing. In practice the indoor unit is a dark, damp box that collects dust and grows mould, and the outdoor coil clogs with lint, pollen and salt. An annual service restores both, keeps the electrical side safe, and gives you a documented maintenance record for warranty purposes.

Quick answer

A split system service in Sydney costs $150–$280 for a single head, with additional heads on a multi-split from $90 each. It takes 45–90 minutes and covers filter cleaning, indoor and outdoor coil cleaning, condensate drain flushing, refrigerant pressure checks, electrical testing and an airflow check. Book annually, or every six months near the coast.

Key takeaways

  • Allow 45–90 minutes per head for a full service
  • Coil and blower cleaning is what removes musty smells for good
  • Drain flushing prevents the water leaks that damage walls and floors
  • Electrical testing catches failing capacitors before they strand you
  • Multi-splits are cheaper per head than servicing single units separately

What we do on a split system service

  • Wash and dry filters; replace perished or crumbling filter media
  • Clean and sanitise the indoor evaporator coil and blower wheel
  • Flush and treat the condensate pan and drain line
  • Degrease and rinse the outdoor condenser coil
  • Check refrigerant pressures and temperature split against spec
  • Measure current draw, test the capacitor and tighten terminations
  • Check bracket security, pipe insulation and outdoor unit levelling
  • Report findings, including anything trending towards failure

Signs your split needs servicing now

  • Musty or sour smell for the first few minutes after start-up
  • Weaker airflow than last summer at the same fan speed
  • Takes longer to reach setpoint, or runs continuously
  • Water marks below the indoor unit
  • Visible dust or black spotting on the louvres and fins
  • Higher summer electricity bills with no change in habits

Coastal and multi-head considerations

From Bondi to Manly to Cronulla, salt attacks the outdoor coil and chassis. Six-monthly rinsing and inspection meaningfully extends unit life, and coil coatings are worth specifying on replacement.

On multi-splits, one outdoor unit serves several heads, so a fault in the outdoor unit affects every room at once. Servicing all heads in one visit costs less per head and gives us the full picture of how the system is balanced.

Frequently asked questions

How often should a split system be serviced?

Annually for typical Sydney homes, and every six months for coastal properties, heavy year-round use, or households with allergies or asthma.

How long does a split system service take?

Around 45 to 90 minutes for one head. A deep chemical clean where the blower wheel is heavily fouled takes longer and is quoted separately.

Will servicing fix a musty smell?

Yes, in most cases. The smell comes from microbial growth on the coil and in the drain pan, which a proper clean and sanitise removes. Heavy fouling needs a deep chemical clean.

Does servicing include refrigerant?

We check pressures as part of the service. If gas is low, that means a leak — we quote leak detection and repair rather than simply adding refrigerant.
