The short answer: once a year for most homes
For a typical Brisbane home, an annual service is enough to keep an air conditioner running reliably. The best time to book is in autumn or spring, before the system is leant on for a hot summer or a cool snap, so anything amiss is found and sorted while technicians are not flat out.
Some systems earn a more frequent schedule. Units near the bay that take in salt-laden air, homes in dusty surroundings, systems that run almost every day of the year, and busy commercial installations all benefit from a service every six months. If you are not sure where your system sits, the simplest rule is once a year as a minimum, and more often if it works hard or lives in a tough spot.
What happens during an air conditioning service
A professional service is more than a quick once-over. A qualified technician works through the parts that wear and the faults that cause most breakdowns, cleaning and checking as they go.
- Clean or replace the filters and clear the indoor and outdoor coils so the system can move air freely.
- Check refrigerant levels and look for leaks, since a system that is low cools poorly and strains the compressor.
- Clear the condensate drain and tray, a common cause of water leaks and shutdowns after a humid, wet spell.
- Inspect the electrical connections, controls and safety switches, and confirm the system cycles and holds temperature correctly.
- Check the outdoor unit is clear of leaves and debris and that the fans run cleanly and quietly.
How often to service, by situation
Not every system needs the same schedule. How hard your air conditioner works, and the conditions it works in, decide how often it should be looked at.
- Most homes: once a year, booked in autumn or spring before peak season.
- Heavy or year-round use: every six months, as the extra run time wears parts faster.
- Coastal and bayside homes: every six months, because salt-laden air corrodes outdoor units and coils.
- Dusty or renovation-affected sites: more often, as dust clogs filters and coils quickly.
- Commercial systems: a scheduled maintenance plan, usually twice a year or more depending on the use and the type of system.
Signs your air conditioner needs a service sooner
Even on an annual schedule, a system will often tell you it needs attention between services. Booking a check when you notice these signs usually heads off a bigger repair later.
- It is taking longer to cool a room, or not reaching the temperature it used to.
- Weak airflow from the vents, which usually points to blocked filters or dirty coils.
- Unusual noises, rattles or vibration from the indoor or outdoor unit.
- Musty or unpleasant smells when the system runs, which can mean a dirty coil or a blocked drain.
- Water pooling near the indoor unit, or the system switching itself off.
- Higher running costs than usual for the same amount of use.
Why regular servicing matters in Brisbane's climate
Brisbane's heat, humidity and storm season are hard on air conditioners. Systems here run long hours through summer, deal with high humidity that loads up the condensate drain, and cop power surges and debris during storms. A system serviced on schedule handles all of that far better than one left until it fails.
Regular servicing keeps a system reliable when you need it most, helps it run efficiently rather than straining against clogged filters and coils, and extends its working life. Just as importantly, a technician often spots a worn part or a small leak early, so a quick fix now avoids a breakdown on the first scorching day of summer. Many manufacturer warranties also expect the system to be serviced regularly, so keeping your records up to date helps protect your cover.
What you can do yourself, and what needs a technician
There is a little you can do between services. Cleaning or rinsing the filters every few weeks during heavy use keeps airflow strong and is the single most useful thing a homeowner can do. Keeping the outdoor unit clear of leaves, garden growth and debris also helps it breathe.
The rest of a service is work for a qualified technician. Checking refrigerant, testing the electricals and safety switches, and clearing the coils and drain properly all call for the right training and tools. Handling refrigerant in particular is licensed work, and Airspect holds the required ARCtick licence (AU42469) along with a QBCC licence (1313788). Our technicians and contractors are qualified, vetted and inducted into Airspect's processes.
