An air conditioning system is a long-term investment in comfort, air quality, and energy efficiency. To protect that investment, regular AC servicing is essential. A well-maintained unit performs better, runs more efficiently, and is far less likely to suffer an unexpected breakdown, especially during those warmer months.

This blog walks you through everything included in a professional service, covering typical aircon technician tasks, what an AC check checklist involves, and the long-term benefits of keeping your system in top shape.

Routine AC servicing is about prevention, not just repair. A well-maintained system performs better, lasts longer, and saves money on long-term repairs.

Why Regular Maintenance Makes A Big Difference

Your AC unit works hard, cooling, ventilating, and filtering the air in your home or business. Over time, wear and tear can impact its performance, increase energy consumption, and even void your warranty.

That’s where regular AC servicing makes a real difference. It helps detect and resolve issues early, keeps the system running efficiently, improves air quality, and reduces the risk of unexpected breakdowns. Whether it’s a residential split unit or a commercial VRF system, a service ensures everything is functioning safely and efficiently.

If you want to cut running costs and extend your system’s lifespan, why regular AC checks matter is something every property owner should consider.

What Happens During A Professional AC Service Visit

A maintenance visit from a certified technician includes a thorough inspection and servicing of key components. Here’s what you can expect:

1. System And Unit Inspection

The technician starts with a full unit inspection to check for signs of damage, wear, or inefficiency. This covers:

  • Internal and external units

  • Casing and mounts

  • Electrical connections

  • Insulation and pipework

Every component is assessed to ensure it’s operating properly and complies with safety standards.

2. Filter And Component Cleaning

A dirty aircon system doesn’t just reduce airflow, it affects your air quality and energy usage. Your aircon technician tasks will include:

  • Cleaning or replacing filters

  • Removing dust from evaporator and condenser coils

  • Checking the blower fan and fins

  • Cleaning vents and grills

This essential aircon components service helps reduce allergens and improves system airflow.

3. Refrigerant Level And Leak Check

One of the most vital parts of the AC check checklist is the refrigerant check. The technician will:

  • Test the current refrigerant level

  • Top up if needed (in line with F-Gas regulations)

  • Check for refrigerant leaks

Keeping refrigerant levels stable ensures efficient cooling and safe operation. If your unit uses R32 gas, you can explore more in our guide on new R32 gas benefits.

4. Thermostat And Control Accuracy Test

An AC system is only as good as its control settings. During servicing, the technician will:

  • Verify thermostat settings and calibration

  • Test programmable or smart controls

  • Ensure consistent temperature readings

This ensures the system runs only when needed, boosting energy efficiency.

5. Drainage System Flush

Blocked condensate drains can lead to leaks and water damage. The technician will:

  • Flush and clear the drain pipe

  • Remove clogs or algae build-up

  • Check for water pooling or mould risks

This step protects your unit and property from unnecessary damage.

6. Electrical Testing And Safety Checks

Every service includes thorough safety checks to prevent electrical risks:

  • Inspecting wiring and terminals

  • Testing the power supply

  • Checking fuse boxes and circuit breakers

  • Ensuring safe earthing

These tests help prevent electrical failures and maintain safe operation.

7. Full Operational Testing

Once all checks and cleaning are complete, the technician runs a full test cycle:

  • Monitors cooling performance

  • Tests fan speed and airflow

  • Listens for unusual sounds or vibrations

  • Confirms all systems are working as intended

This confirms the system is running at optimal capacity before the visit concludes. If it’s your first service, you can arrange a full AC inspection to establish a maintenance baseline.

How To Prepare For Your AC Maintenance Visit

Before your technician arrives, here are a few ways to help:

  • Ensure clear access to your units

  • Note any unusual behaviour you’ve noticed

  • Switch off the system if requested before inspection

  • Keep pets and children away during the visit

A little preparation ensures a smoother and quicker service.
