If there’s one thing every Aussie knows, it’s that summer doesn’t muck around. The heat rolls in fast, the humidity kicks up, and before you know it, your aircon is running full tilt just to keep the house livable. But here’s the thing most people forget: your aircon works its hardest right when it’s least prepared—after months of barely being used.
So before those scorchers arrive, it’s worth asking: Is your aircon actually ready for summer? And just as important: When should you call in an expert to take a look?
Let’s run through the signs, the must-do maintenance, and when to bring in a proper tradie (hint: ServiceSeeking.com.au has you sorted).
Air conditioners don’t magically stay in good nick on their own. Dust builds up, parts wear down, gas levels drop, and filters clog. Even if your unit seems fine, a quick pre-season check can prevent:
Higher power bills
Weak airflow and poor cooling
Strange smells or noises
Mid-summer breakdowns (always on the hottest day, of course)
Think of it like giving your car a quick service before a long road trip. Sure, you might get away without it… but do you really want to risk it?
Before you jump straight to booking a tradie, there are a few simple checks you can do yourself. These won’t replace a proper service, but they’ll give your unit the best chance to run efficiently.
This is the easiest aircon job and probably the most important. Dirty filters restrict airflow, make your system work harder, and can blow dust back into your home. Most filters can be removed, rinsed and dried before popping back in.
If you can’t remember the last time they were cleaned… it’s definitely time.
Your outdoor condenser needs space to breathe. Clear away leaves, sticks, weeds, and anything else blocking the vents. While you’re out there, look for signs of rust, unusual noises, or animals nesting inside (yes, it happens more than you think).
Don’t wait for the first 35-degree day to fire it up. Switch it on in late spring and see how it performs.
Ask yourself:
Is the airflow strong?
Does it cool quickly?
Does it make any strange rattling or humming noises?
Does it smell musty?
Does the remote respond properly?
Small issues now could become big issues when you’re relying on it daily.
DIY can only get you so far. If your system ticks any of the boxes below, it’s time for a professional to take a look.
If your aircon is blowing warm or barely cool air, it could be due to low refrigerant, a blocked coil, or a failing compressor. These are not DIY-friendly fixes. A licensed aircon technician can diagnose the issue properly.
Grinding, squealing, banging, or rattling noises all point to trouble. It could be anything from a loose fan to a motor on its way out. Don’t ignore it—these issues can escalate (and get more expensive) fast.
A musty smell usually means mould. A burning smell could be electrical. Either way, that’s a clear sign to bring in an expert before the problem worsens or becomes unsafe.
Water dripping from the unit or pooling underneath could mean a blocked drain or a bigger mechanical issue. Refrigerant leaks are also possible—and dangerous—so it’s best not to risk it.
If your electricity bill jumps for no obvious reason, your aircon might be running inefficiently. A service can get it back to peak performance so you’re not paying more than you should.
A proper aircon technician does much more than a quick clean. When you book a service, they’ll typically:
Check refrigerant levels
Inspect electrical connections
Deep-clean coils and internal components
Test the thermostat
Check drainage and clear blockages
Look for early signs of wear and tear
Make sure everything is running safely and efficiently
This kind of service extends the life of your system and keeps your cooling costs in check. It’s one of those things you only appreciate after you’ve had it done.
In most Aussie homes, a yearly service is ideal—especially before summer. If you live somewhere hot and humid, use your system every day, or have pets, you might need more frequent check-ups.
Different systems have different needs.
Common signs you need an expert:
Ice forming on the pipes
Weak airflow from the indoor head
Fan not spinning in the outdoor unit
Water dripping from inside the house
Split systems are relatively simple for a tradie to inspect and repair, and most issues can be fixed quickly.
Because ducted systems have more components—ductwork, vents, zoning, thermostats—they need more specialised attention.
Call a tradie if you notice:
Uneven cooling between rooms
Whistling or buzzing noises in the ducts
Poor airflow across multiple vents
Thermostat not responding or misreading temperatures
Duct systems can hide problems you won’t see until the unit fails, so a proper inspection is essential.
It’s tempting to tinker, especially if you’re handy, but air conditioning systems involve electrical components, sealed refrigerant, and complex parts. In Australia, only licensed technicians are allowed to handle refrigerant—and for good reason.
A dodgy DIY fix can cause:
Void warranties
Electrical hazards
Refrigerant leaks
More expensive repairs down the track
If you’re unsure… call a pro. It’s not worth the risk.
If you’re already thinking, “Yep, my aircon needs a proper look,” you’re not alone. Most homeowners don’t realise something’s wrong until the sweat starts rolling and the system can’t keep up.
Jumping on it early means:
Better cooling
Lower bills
Fewer surprises
A much more comfortable summer
