How Often Should You Service Your Air Conditioner? | Brisbane Guide

AC Maintenance Schedule, Costs and Why It Matters for Efficiency

Regular air conditioning servicing keeps your system running efficiently, extends its lifespan and prevents expensive breakdowns. In Brisbane's subtropical climate where AC runs hard for 6 to 8 months of the year, maintenance is not optional — it is essential. For homeowners across North Lakes, Redcliffe, Mango Hill, Chermside and Aspley, here is the recommended maintenance schedule.

Recommended AC Service Schedule

What Does a Professional AC Service Include?

• Filter cleaning or replacement
• Evaporator and condenser coil inspection
• Refrigerant level check
• Electrical connection inspection and tightening
• Thermostat calibration
• Drain line inspection and clearing
• Airflow measurement
• Overall performance assessment

What Happens If You Do Not Service Your AC?

1. Higher Running Costs

Dirty filters and coils restrict airflow, forcing the compressor to work harder and use more electricity. A neglected AC can use 15 to 25 percent more energy than a well-maintained one.

2. Reduced Cooling Performance

Blocked filters and dirty coils reduce the system's ability to cool effectively. You end up setting the thermostat lower, which increases costs further.

3. Shortened Lifespan

A well-maintained air conditioner lasts 15 to 20 years. A neglected one may fail in 8 to 10 years — meaning you pay for a replacement much sooner.

4. Expensive Breakdowns

Small issues caught during routine servicing cost far less to fix than major failures. A compressor replacement can cost $2,000 to $4,000 — often more than the system is worth.

5. Poor Air Quality

Dirty filters and mouldy coils circulate dust, allergens and mould spores through your home. This is particularly concerning for families with asthma or allergies.

AC Service and Maintenance Costs

The Electrical Side of AC Maintenance

Air conditioning systems have electrical components that need periodic checking:

• Dedicated circuit and isolator switch condition
• Wiring connections at the indoor and outdoor units
• Circuit breaker and safety switch operation at the switchboard
• Surge protection to prevent compressor damage from power surges

Using ceiling fans alongside your AC reduces the load on the system and extends its life.

Frequently Asked Questions

How often should I service my air conditioner?

Have a professional service annually before summer. Clean filters yourself every 4 to 6 weeks during heavy use.

How much does an AC service cost in Brisbane?

A standard split system service costs $120 to $250. Deep cleans and ducted system services cost more.

Can a dirty filter increase my electricity bill?

Yes. Dirty filters can increase AC running costs by 15 to 25 percent by restricting airflow and forcing the compressor to work harder.

How long should an air conditioner last?

A well-maintained split system should last 15 to 20 years. Without regular servicing, lifespan drops to 8 to 10 years.

Do I need an electrician for AC maintenance?

For electrical components — circuit checks, wiring, switchboard and surge protection — yes. For refrigerant and mechanical servicing, an AC technician is needed.
