Note:
It is normal for the indoor aircon unit or the external outdoor compressor to produce a low level vibration or noise. However, the sound produced should not be excessively.
Here are the possible reasons why the Air Conditioner may be excessively noisy:
- A dirty fan coil or condenser caused the vibration noise
- A dirty fan coil can also produce a noisy sound
- The aircon components may be loosely installed
- Aircon components are defective
If possible, you may attempt a basic servicing such as:
- Remove the air filter from indoor unit, hose water through it, dry it with a cloth, then put it back.
- Call for general Aircon service team to clean the indoor and outdoor.
