Air conditioners (aircons) are a critical part of keeping your space comfortable, particularly during Sydney’s hot summer months. But when it comes time for servicing, many people ask, “How much does it cost to service an air conditioner?”

Let’s break down the aircon servicing costs in Sydney. We will help you understand the factors that determine the overall price so you can plan accordingly.

What’s Included in a Basic Aircon Service?

A standard service involves:

  • Filter cleaning 
  • Cleaning of evaporator and condenser coils
  • Checking refrigerant levels
  • Inspection of the air conditioner’s overall function
  • Cleaning drain lines
  • Checking for wear and tear

A good service technician will ensure your system is running as efficiently as possible to avoid any potential issues.

When it comes to air conditioning service, costs can vary significantly. Factors such as the type of system, its age, and the extent of the issue, all play a role in determining how much you’ll pay.

The average aircon service cost in Sydney in 2025 is within a range of $100 to $300 for a basic service. This could include things like filter cleaning, checking for refrigerant leaks, or doing a general system checkup.

Aircon Repairs and Their Costs

Basic servicing is crucial, but sometimes problems arise, requiring repairs. Here’s a look at common aircon problems and their repair costs in Sydney:

1. Refrigerant Leak – Estimated Cost: $400 – $1,500

Refrigerant leaks are a fairly common issue in air conditioners. They lead to poor cooling performance and higher energy costs. If you suspect your air conditioner is leaking refrigerant, it’s important to address the issue as soon as possible.

The repair cost mentioned above depends on the size of the leak and the type of refrigerant used. If your unit is older or uses more expensive refrigerants, expect to pay on the higher end of the range.

2. Dirty or Clogged Filters – Estimated Cost: $30 – $150

Clogged or dirty air filters reduce airflow and make your air conditioner work harder, leading to reduced efficiency and higher running costs. While cleaning filters is part of regular maintenance, you may need to replace them if they’ve been neglected for a while. Depending on the type of filter and its accessibility, this is a quick and cost-effective fix.

3. Sensor Problems – Estimated Cost: $250 and up

Temperature sensors in your air conditioner continuously monitor the indoor climate to maintain optimal cooling performance. If a sensor malfunctions, it will prevent the system from maintaining the desired temperature. The exact cost depends on the model and brand of the air conditioner.

4. Drainage Issues – Estimated Cost: $250 – $350

Clogged or leaking drainage lines can cause water damage in your home and lower the system’s efficiency. Clearing the lines and fixing any blockages is important to avoid bigger issues. If the blockage is severe, the repair cost might go higher, especially if the issue involves replacing drainage parts.

5. Faulty Thermostat – Estimated Cost: $250 – $1,900

A faulty thermostat can prevent your air conditioner from regulating the temperature properly.
The cost can vary based on whether the thermostat needs a simple recalibration or a complete replacement.

6. Frozen Evaporator Coils – Estimated Cost: $250 – $400

Frozen coils are often caused by a lack of airflow due to dirty filters or blocked vents. This can cause the system to stop cooling properly. The cost mentioned usually covers the thawing of the coils, the cleaning of filters, and ensuring the system is functioning again.

7. Electrical Control Failure  – Estimated Cost: $400 – $1,600

Over time, the electrical components, like the compressor and fan controls, can wear out. If your air conditioner keeps turning off or has trouble running, you will need an electrical control repair.

How to Save on Air Conditioner Repair Costs

  • Regular Maintenance: Have your air conditioner serviced at least once a year to ensure it stays efficient and catches any potential issues before they turn into expensive repairs.
  • Address Small Problems Early: Don’t let minor issues slide. Fixing small problems early can prevent costly repairs down the road.
  • Check Your Warranty: Always check if your air conditioner is still under warranty before you pay for any repairs. You might find that some repairs are covered.

Aircon Fix vs. Replacement: Which is the Best Option?

At some point, you have to choose between fixing your air conditioner or replacing it. While air conditioner repair is cheaper, sometimes a replacement is more cost-effective in the long run.

1. When to Fix:

  • The unit is relatively new (less than 10 years old).
  • Repairs are minor, such as a clogged drain or filter replacement.
  • Your unit is still under warranty, covering the cost of repairs.

2. When to Replace:

  • The unit is more than 10 years old.
  • Repairs are both frequent and expensive.
  • The unit uses outdated refrigerants that are no longer available or are costly to replace.
  • Energy bills have significantly increased due to poor efficiency.

Conclusion

So, how much to service air conditioner in Sydney? The cost is influenced by several factors, as highlighted above. If your unit is older and frequently breaking down, a replacement is more cost-effective in the long run.
