Why Your Aircon Is Making Noise

Some noises are harmless and some are warnings. The difference matters, because a bearing that is starting to fail keeps running for a while, then seizes and takes the fan motor with it.

The homes here are mostly single-storey brick veneer built from the 1970s through the 1990s, and plenty still run original split systems and ducted units. Age shows up as noise before it shows up as a breakdown, so a new sound from an old unit is worth a call.

What you get

What Different Noises Usually Mean

Cheapest causes first, because not every noise is a repair bill.

Rattling

A loose panel, a tired fan blade or leaf litter pulled into the outdoor unit. The established gardens on the half-acre Castieu Estate blocks feed plenty of debris into units sitting under mature trees.

Buzzing

Often a failing capacitor or a compressor struggling to start. It runs, but not for long.

Clicking that never stops

A relay or controller fault rather than a mechanical one.

Whistling or hissing

Ductwork leaking in the ceiling, or a refrigerant issue that needs a licensed technician.

Grinding or screeching

Motor bearings on the way out. This one stops the fan if it is ignored.

A grinding system is a system that is about to stop. Turn it off at the wall and call us rather than running it into the ground.

How it works

Safe Checks Before You Call

A couple of checks cost nothing and rule out the simple causes.

  1. 01

    Step 1

    Look at the outdoor unit for leaves, twigs or anything leaning against it, and clear the space around it.

  2. 02

    Step 2

    Check that the indoor unit's filter is clean, because a choked filter makes the whole system louder.

  3. 03

    Step 3

    Note when the noise happens: on start-up, all the time, or only in heating mode. That detail speeds up our diagnosis.

Leave the rest alone. Capacitors, motors, refrigerant and wiring are licensed work, and opening a unit can turn a small repair into a big one.

When Noise Means Call an Aircon Technician

Some sounds should not wait. Call us the same day if you notice grinding or screeching from the outdoor unit, or a buzzing that started suddenly out of nowhere.

Noise paired with another fault is a bigger warning. If the unit is loud and also struggling on our air conditioner not cooling page, or pushing out the problems on our warm air from the vents page, the compressor is usually under strain.

In detail

Noisy Ducted and Split Systems We Also Clean

Noise is often a symptom of a system that has not been looked at in years. Dust-caked fans run out of balance and get louder every summer.

A proper air conditioning clean quiets most of them down. If the unit is past saving, air conditioning replacement costs less than feeding a system that rattles through another season.

Good to know

Frequently asked questions

Can I keep running my aircon until someone looks at it?

Not if the noise is grinding or screeching, because a failing bearing or motor gets worse every hour it runs, and turning the unit off at the wall costs nothing.

What does a rattling noise usually mean?

Most rattles come from loose panels, a tired fan blade or debris in the outdoor unit, and the mature gardens on the bigger Castieu Estate blocks feed plenty of leaf litter into them.

How much does a noise diagnosis cost?

We quote the full figure before any work starts under Fixed Upfront Pricing, so you know the cost of the diagnosis and the repair before we touch a tool.

Yes, we cover Salisbury East, Salisbury Park, Salisbury Plain, Salisbury and Para Hills on the same run, with a full ARC refrigeration and air conditioning licence.
