What you get
What That Cooling System Noise Is Telling You
Different sounds point to different faults, so the noise itself is the first clue. Here is what each one usually means:
Rattling or clicking
Buzzing
Screeching or grinding
Bubbling or hissing
A unit that is loud and cooling poorly at the same time needs a proper look, not a guess. Our air conditioning repairs page covers the broader fault list.
In detail
Cheapest Fixes First: Common Causes of Aircon Noise
Start with the causes that cost the least to fix. Most noisy units we see across the suburb's 1970s and 1980s brick stock come down to one of these:
Blocked filters
A choked filter makes the whole system strain, and strain sounds like vibration. It is the cheapest fix on the list and a professional clean usually settles it.
Outdoor debris
The Craigburn release kept mature gum cover, so leaf litter and twigs get sucked into outdoor coils and fans all summer. A clear-out often stops the rattle on the spot.
Loose mounts
Volume-era installs from the 1970s and 1980s sometimes ran tired brackets and screws that have worked loose over decades. Tightening or replacing them is a small job.
Worn motor or compressor
This is the expensive end, and it is honest-work territory. We diagnose before quoting and tell you plainly when a repair beats a replacement.

Safe Checks Before You Book an Air Conditioning Repair
Two minutes of checking can save a call-out, and none of it puts you at risk. Try these before you ring:
Turn the system off
Check the filters
Look at the outdoor unit
Note when it happens
Leave anything electrical or refrigerant-related alone. Capacitors hold charge and refrigerant is a licensed-handling job under our ARC Licence L162586, RAC01 - Full Refrigeration and Air Conditioning Licence.

When Noise Means Call a Split System Technician
Some sounds should not wait, and a hot night is the wrong time to find out which. Call us straight away if:
- The compressor screeches or grinds while running
- The noise started after a storm or power event
- The unit is loud and blowing weak or warm air
- You smell burning alongside the noise
A grinding compressor that keeps running usually fails completely, and that decision is much easier made in July than mid-heatwave. If the noise comes with warm air, our blowing warm air page covers that pairing.

Air Conditioner Noise FAQs
Can I keep running a noisy air conditioner?
Not for long, because a grinding or screeching compressor or fan motor tends to fail completely if it is run on, and that turns a modest repair into a full replacement decision.
Why is my outdoor unit rattling?
On the treed blocks from the Craigburn release, gum leaves and small twigs get pulled into the outdoor coil and fan, so the first check is always a clear-out before anyone blames the hardware.
Is a buzzing noise serious?
It can be, because a steady buzz often points to a failing capacitor, a loose electrical connection or a compressor struggling to start, and those are not faults to run a unit on.
How much does a noise repair cost?
Every job is quoted under Fixed Upfront Pricing before any work starts, so you see the full figure in writing and there are no hourly rates and no bill shock at the end.
