Understanding Aircon Noise Levels


Aircon noise primarily originates from various components such as fans, compressors, and the airflow itself.

  • Fans: Produce noise during operation, especially at higher speeds.
  • Compressors: Generate noise as they compress refrigerant, often perceived as a humming or buzzing sound.
  • Airflow: The movement of air through ducts and vents can also create noise.

Types of Noise:

  • Humming: Commonly associated with the compressor.
  • Buzzing: Often indicates electrical issues or loose components.
  • Rattling: Can suggest loose parts or debris in the system.

While some noise is inherent to aircon operation, excessive noise can usually be mitigated through proper selection and maintenance.

How Aircon Noise is Measured

Aircon noise is measured in decibels (dB), a unit that quantifies sound intensity. The decibel scale is logarithmic, meaning a small increase in dB represents a significant increase in noise level.

Decibels (dB):

  • Low Noise: 30-40 dB (comparable to a whisper).
  • Moderate Noise: 40-60 dB (normal conversation).
  • High Noise: Above 60 dB (office environment noise).

Typical Noise Levels:

  • Window Units: Generally 50-60 dB.
  • Split Systems: Around 30-50 dB.
  • Central Systems: Varies depending on ductwork and insulation but typically quieter.

Lower decibel ratings indicate quieter units. Aim for units with a noise level of 40 dB or lower for minimal disturbance.

Impact of Noise Levels on Home Environment

Noise levels can significantly affect the comfort and health of household members. High noise levels can disrupt relaxation and interfere with activities like watching TV or conversing.

Prolonged exposure to excessive noise can lead to increased stress levels, poor sleep quality, and even long-term hearing issues.

Consider the placement of the aircon unit to minimize noise disturbance in living and sleeping areas, ensuring a quieter and more comfortable environment.
