Common problem
Air Conditioner Making Noise in Andrews Farm
An air conditioner making noise is telling you something is loose, worn or blocked, and Andrews Farm homes send us plenty of these calls. The good news is that most noisy aircon faults are small and cheap to fix, provided you catch them before the component fails completely.
What this page covers. What each sound usually means, what you can safely check yourself, and when it is time to call us.
If the noise has stopped you cooling the house on a hot day, our air conditioning repairs team diagnoses before it quotes, so you only ever pay for the real fault.
Why Your Air Conditioner Is Making Noise
Every sound points somewhere different, so listen properly before you pick up the phone.
Rattling or buzzing
Grinding or screeching
Clicking at startup
Banging or clunking
Most homes here are detached project builds from the 1990s onward, and brick veneer on a small estate lot transmits fan vibration straight into the wall frame. That is why a minor bracket rattle can sound like a much bigger problem from inside the lounge room.
How it works
Noisy Aircon Causes, Cheapest First
We always rule out the simple stuff before we talk about parts, because the cheap cause is the common cause.
- 1
Loose panels or screws
A panel vibrating against the frame is a five-minute fix.
- 2
Debris around the outdoor unit
Leaves and plastic find their way into fan shrouds on closely spaced blocks.
- 3
Blocked or dirty filters
A choked filter makes the whole unit labour, and labouring units get loud.
- 4
Worn fan bearings
This is the grinding one, and the motor or fan needs replacing before it seizes.
- 5
Refrigerant line vibration
Copper lines rubbing a wall or bracket hum, and a simple re-clip quiets them.
If the noise comes with warm air or ice on the pipes, stop the unit and read our pages on an air conditioner blowing warm air or an air conditioner frozen, because those faults need a licensed technician rather than a tweak.
Safe Checks Before You Call for Air Conditioning Repairs
A couple of checks cost nothing and sometimes solve it outright.
Check the filter
Clear the outdoor unit
Feel for loose panels
Note when it happens
Do not open the unit casing or touch electrical components. Refrigerant and mains wiring are licensed work under our ARC licence, and a DIY poke around can turn a warranty repair into a replacement.
Do not wait on this
When a Noisy Cooling System Needs a Technician
Grinding, screeching and banging all mean stop using the system and book a repair. A bearing that seizes takes the fan motor with it, and on a ducted system that repair costs several times what the bearing would have.
Think of the neighbours too. Estate lots here sit close together, and a failing outdoor unit running through a 40-degree night does not win friends down the fence line.

Questions
Air Conditioner Noise FAQs
Is a noisy air conditioner dangerous to keep running?
A rattle is usually harmless, but grinding or screeching can mean a failing motor bearing, and running it hard risks turning a small repair into a full replacement.
Why does my unit get louder in summer?
Long heatwave runs through dry Adelaide summers wear fans and bearings faster, and a unit working flat out for days amplifies any vibration that was already there.
Can you fix noisy units in the newer western streets?
Yes, we work the whole suburb every week, from the first 1990s sections to the 2011 westward extension, and we diagnose the noise before we quote the fix.
How much does a noise repair cost?
It depends on the fault, from a simple panel or bracket fix to a fan motor, and we give you a fixed quote in writing before any work starts.
