How Often Should I Service My Air Conditioner? | Expert Advice From A Qualified Electrician
Is your air conditioner running at its best? Or are you risking high power bills and poor air quality without even knowing it?
Many homeowners ask this question: How often should I service my air conditioner? It’s a smart one and the answer can make a big difference to your comfort, your wallet, and the lifespan of your unit.
Whether you’re using a split system, ducted unit, or reverse cycle air conditioner, regular maintenance is crucial. In this detailed guide, we’ll walk you through exactly when and why to service your aircon, what happens if you don’t, and how Connex Electrical can help you stay cool and energy-efficient all year round.
Why Regular Air Conditioner Servicing Matters
Your air conditioning unit works hard especially in our hot and humid Australian climate. Dust, mould, and bacteria build up quickly in filters and internal components, reducing efficiency and compromising the air you breathe.
Neglecting your aircon doesn’t just mean discomfort it can mean:
Higher electricity bills
Reduced cooling performance
Health issues from poor air quality
Breakdowns that could’ve been avoided
Costly repairs or complete replacement
At Connex Electrical, we’ve seen it all. That’s why we recommend scheduling your service at least once a year, even if everything seems to be working fine.
So, How Often Should I Service My Air Conditioner?
Residential Units
Minimum: Every 12 months
Ideal: Every 6 months (especially before summer and winter)
If you use your unit year-round for both cooling and heating a biannual service is your best bet. This ensures that your aircon is ready to perform at peak efficiency during the times you need it most.
Commercial Properties
Offices, shops, and rental properties often require quarterly servicing due to high usage and health regulations. Clean air is a must for employees and customers alike.
Tip: Rental property owners are legally obligated to maintain a safe, clean, and functioning air conditioning system under tenancy laws in most Australian states.
Signs Your Air Conditioner Needs Servicing Sooner
Even if it hasn’t been a full year since your last service, your air conditioner might already be overdue. Here’s what to look out for:
Air isn’t as cool as it used to be
Weak airflow from the vents
Musty or unpleasant smells
Strange noises (clicking, buzzing, or rattling)
Water leaks or excess condensation
Higher than usual energy bills
If you’ve noticed any of the above, it’s time to book a service right away.
What’s Included in a Professional Air Conditioner Service?
At Connex Electrical, our licensed electricians perform a thorough check that covers:
Cleaning filters and fan coils
Checking gas levels and refilling if required
Inspecting ductwork (for ducted systems)
Verifying thermostat calibration
Tightening electrical connections
Checking airflow and return vents
Looking for signs of wear, rust, or damage
Ensuring no refrigerant leaks
We also offer advice on when to upgrade your unit for better energy efficiency especially if your system is over 10 years old.
How Regular Servicing Saves You Money
Think of air conditioner servicing like getting your car serviced. You wouldn’t wait for the engine to fail before getting it checked, right?
A regular air conditioning service:
Improves energy efficiency by up to 30%
Extends the life of your unit
Prevents expensive breakdowns
Improves air quality, reducing health risks
Keeps your warranty valid (most manufacturers require yearly servicing)
When your air conditioner runs smoothly, it uses less power to cool your space. And that’s money straight back in your pocket.
DIY Maintenance vs Professional Servicing
There are a few tasks homeowners can do between services:
Clean or replace filters every 1–2 months
Clear any obstructions from vents
Gently wipe the exterior of the indoor and outdoor units
But leave the technical work to the pros.
Trying to clean internal components or handle refrigerant yourself can be dangerous and may void your warranty. At Connex Electrical, our experienced team knows exactly what to look for and how to fix it safely.
The Best Time of Year to Service Your Air Conditioner
It’s ideal to book your air conditioner service before peak seasons. That means:
Spring – prepare for summer heat
Autumn – prepare for winter heating
Servicing during the off-season also helps you beat the rush and ensures availability with your preferred technician.
