Weird Sound Your Aircon Makes & What It Means

Air conditioning is an essential part of our everyday life in Singapore. With prolonged usage, all electrical appliances will require some form of servicing & repair due to wear and tear.

If you have owned an air-conditioning unit for more than 2-3 years, chances are, you may start to hear squealing, buzzing, or other weird noise when you run your aircon.

Let us help you identify the common noises and what they mean.

Squealing Noise

If you are hearing a squealing noise when your aircon is running, chances are, you may have a faulty bearing within your aircon.

These bearings are used to hold and rotate the aircon blower in a modern aircon system which may turn faulty after an extended period of usage.

For such cases, we recommend getting a professional aircon specialist to check and inspect as it requires the dismantling of the entire fan coil unit.

Buzzing Noise

When using your aircon and you hear a buzzing noise, chances are, you may have a loose screw or faulty part within your aircon fan coil unit that causes it to vibrate.

We recommend getting a professional aircon specialist to check and inspect the problem as this process may require the dismantling of the entire fan coil unit.

Loud Blowing Noise with Uneven Air Flow

If you are hearing a loud blowing noise from your aircon and experience uneven cold aircon flow from your aircon, chances are, you may have a dirty blower.

As you use your aircon for an extensive period without servicing & cleaning, dust & dirt will build up within the aircon which causes loud blowing noises and uneven airflow.

In this instance, we would recommend getting a professional aircon specialist to do a chemical overhaul on your aircon fan coil unit. With a chemical overhaul, you will be able to thoroughly wash & clean the hard-to-reach parts of your aircon ensuring all dust & dirt are removed from your aircon fan coil unit.
