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:
- Removing the indoor fan coil unit filter to wash
- Using a vacuum to remove dust and debris to clean the fin of the aircon
- Using a rag/towel to absorb the water in the water tray
