The service

## What Is Noisy Aircon Repair?

A new noise usually means something has worked loose or is wearing out. Rattling often comes from a loose cover or fan blade, buzzing from a capacitor or electrical part, clicking from a relay, and grinding from a failing fan bearing or motor.

Outdoor units on HDB aircon ledges can also vibrate through worn brackets or mounting pads and disturb neighbours. We trace the source, explain it and fix it after a fixed quote. Repairs start from S$60.

### What's included

-   Indoor and outdoor noise diagnosis
-   Fan blade, bearing and motor checks
-   Capacitor and relay testing
-   Bracket and mounting pad check on the ledge
-   90-day workmanship warranty

## What Is That Noise? A Quick Guide

Is your aircon suddenly louder than the telly? We handle noisy aircon repair in Jurong West and Jurong East, and the sound usually tells us where to look before we open a single panel.

Different sounds point to different problems. Here is what we usually find.

| Sound | Where | Likely cause |
| --- | --- | --- |
| Rattling | Indoor | Loose cover, screw or cracked blower wheel blade |
| Rattling or vibration | Outdoor | Loose grille, worn bracket or anti-vibration pads |
| Buzzing | Outdoor | Weak capacitor, worn contactor, struggling compressor |
| Clicking | Indoor or outdoor | Relay switching repeatedly, control fault |
| Grinding or squealing | Indoor or outdoor | Worn fan bearing or fan motor |
| Gurgling | Indoor | Water or air in a partly blocked drain line |

Timing matters too. According to the Singapore site aircons.sg, a single click as the compressor starts is normal relay action, but continuous clicking points to an electrical fault.

## Indoor Unit Noises

Inside the room, most noises come from the fan section. A blower wheel that is caked with dirt can go off-balance and wobble. A cracked blade can tick against the housing every turn. A **fan motor** with a dry bearing starts to whine and then grind.

Bedroom units are where noise bothers people most, since they run all night. If the sound started after a recent knock or an 

aircon servicing

[/ →](/)

 visit, a cover may simply not be clipped in properly. That is a quick fix.

Before you call, try these three checks:

-   Press gently around the front cover to see if the rattle changes.
-   Look at the filters. Quiet.sg, a Singapore noise-control site, notes that dirty filters make the fan motor strain, and it suggests cleaning them monthly.
-   Note whether the sound happens at start-up, on full fan or all the time.

## Outdoor Unit Noises on the HDB Ledge

Outdoor units sit on the **aircon ledge** outside your window. Over the years the brackets loosen and the rubber pads under the unit harden or crack. Vibration from the **condenser fan** and compressor then travels into the wall. You may hear it as a hum through the bedroom, and so may your neighbours above and below in the **HDB flat**.

Age plays a part. VD Aircon Services says units are often within noise limits when new, but 4 to 6 years in, worn compressor bearings begin to shake the bracket. The unit itself may not be loud. The bracket carries a low-frequency hum into the wall, and that is what neighbours hear.

Here is what we do on the ledge:

-   Check the bracket bolts for looseness or rust.
-   Replace hardened or cracked pads.
-   Inspect the fan blade and motor.
-   Listen to the compressor start.

Many ledge noises are fixed in a single visit. If the bracket itself is corroded, it needs replacing. Grade 304 stainless steel is the standard material for HDB brackets, according to Saces.sg’s 2026 HDB installation guide.

One more thing worth knowing: aircons.sg points out that there is no separate NEA decibel limit that applies between two HDB units. The NEA boundary guideline is measured at the site boundary. So a friendly word with your neighbour, plus a quick fix on your side, usually works best.

## When a Noise Means a Part Is Failing

Some sounds are early warnings:

-   **Buzzing that gets louder** often means a capacitor is weakening. When it fails, the unit stops cooling.
-   **Grinding** means a bearing is wearing. Left alone, the motor can seize.
-   **Repeated clicking without starting** suggests a relay or control problem.

Capacitors do not last forever. Aircons.sg puts their typical lifespan at 4 to 6 years in Singapore heat, so an older unit with a new buzz is a good suspect. A 2026 price guide from Saces.sg lists a capacitor repair at roughly $80 to $150 including labour.

Catching these early is usually cheaper than waiting for a breakdown. If the unit has already stopped, see our 

aircon repair

[/aircon-repair/ →](/aircon-repair/)

 page.

## Getting the Best Diagnosis

Noises can come and go. A short video with sound is the best clue you can give us.

When it happens, do this:

-   Record a short video with sound and send it on WhatsApp.
-   Tell us if it is worse at start-up, at night or when the compressor kicks in.
-   Mention how many units you have, so we can tell which one is the culprit.

Before the visit, read how to 

prepare your home for the technician

[/guide/prepare-home-for-aircon-servicing/ →](/guide/prepare-home-for-aircon-servicing/)

, especially clearing window access to the ledge. Then send us that video on WhatsApp, and we will sort out your noisy aircon repair as soon as we can.

Got questions?

## Noisy Aircon Repair FAQs

### Why is my aircon making a rattling noise?

Rattling usually comes from a loose front cover, a loose screw, a cracked blower wheel blade or something touching the fan. Outdoors, a loose grille or worn mounting can rattle.

### Why is my outdoor aircon unit buzzing?

Buzzing often points to an electrical part such as a weak capacitor or a worn contactor. It can also come from the compressor struggling to start. It is worth checking before the part fails.

### My aircon clicks when it starts. Is that a problem?

A single click is normal as the relay switches. Repeated clicking without the unit starting suggests a relay, capacitor or control fault.

### What causes a grinding noise?

Grinding usually means a fan bearing or fan motor is wearing out. Left alone it can seize, so it is best to replace it early.

### Can you fix a noisy outdoor unit on my HDB ledge in Jurong West?

Yes. We check brackets, mounting pads, fan blades and motors on the ledge and fix the source of the vibration or noise after a fixed quote.

### How much does noisy aircon repair cost?

Repairs start from S$60. Tightening and pad replacement are at the lower end; a fan motor replacement costs more. You get a fixed quote first.

### Will servicing make my aircon quieter?

Sometimes. A dirty, unbalanced blower wheel can hum or wobble, and cleaning helps. Mechanical wear needs a repair.

### Is there a warranty?

Yes. All work carries a 90-day workmanship warranty.

### Still have a question?

Send us a WhatsApp with your units and the problem. We reply with a fixed quote.
