Most Sydney homeowners never service their air conditioner until it breaks. That’s the most expensive way to do it. Here’s what we recommend — and why it matters for your system’s lifespan and your energy bills.
The Short Answer
Residential systems: once a year. The best time is autumn — before you rely on it for heating through winter.
Commercial systems: twice a year. Before summer and before winter.
What Happens If You Don’t Service It?
- Blocked filters reduce airflow by up to 40%, making the system work harder and costing more to run
- Dirty coils reduce efficiency and can cause the system to freeze up in summer
- Low refrigerant (from small leaks) means poor heating and cooling performance
- Electrical faults go undetected until they become expensive failures
- System lifespan drops from 15-20 years to 7-10 years without regular maintenance
What Does a Service Include?
A proper air conditioning service includes: filter clean, coil clean (indoor and outdoor), refrigerant pressure check, electrical connections check, drain clear, thermostat calibration, and a full system test run. It takes about an hour for a split system.
