In Brisbane’s climate, your air conditioner works hard for much of the year — and like any hard-working machine, it runs better and lasts longer with regular servicing. But how often is enough? Here’s a straightforward guide for Brisbane homes and what a proper service actually involves.
How often should you service your air conditioner?
As a general rule, a split system should be serviced once a year, and a ducted system at least once a year too — ideally before the heavy-use seasons (heading into summer for cooling, and into winter if you use it for heating). Homes with pets, dusty environments, or units that run year-round may benefit from a service every six months. Commercial and high-use systems usually need more frequent attention.
Why regular servicing matters
- Lower running costs — a clean, well-tuned system uses less power to reach the same temperature.
- Healthier air — servicing removes the mould, dust and bacteria that build up in coils and filters, which is especially important in Brisbane’s humidity.
- Fewer breakdowns — small issues get caught before they become expensive failures, usually on the hottest day when you need it most.
- Longer lifespan — regular care can add years to the life of your unit.
- Warranty protection — many manufacturers require evidence of regular servicing to honour warranty claims.
What’s included in an air conditioning service?
A professional service typically covers cleaning or replacing filters, cleaning the indoor and outdoor coils, checking refrigerant levels and pressures, clearing the drainage line, inspecting electrical connections, and testing the system’s overall operation. For units affected by Brisbane’s humidity, a chemical clean to remove mould is often recommended — this goes deeper than a standard filter clean.
Signs your air conditioner needs servicing sooner
Don’t wait for the annual service if you notice weak airflow, the unit not cooling or heating properly, unusual smells (a musty smell usually means mould), strange noises, water leaking from the indoor unit, or a sudden jump in your power bill. These are all signs the system needs attention.
