1. Common causes of air conditioning noise
Air conditioning noise is usually caused by the following reasons. The specific manifestations and possible causes are as shown in the table below:
| Noise type | Possible reasons | Frequency of occurrence (proportion of user feedback) |
|---|---|---|
| buzz | Compressor is aging or unstable installation | 35% |
| click | Fan blades collide or foreign matter enters | 25% |
| sound of running water | Refrigerant flow or pipe blockage | 20% |
| high-pitched howl | Motor bearings are worn or lack of oil | 15% |
| Vibration sound | Loose bracket or wall resonance | 5% |
2. How to solve the problem of air conditioning noise
For different noise types, the following solutions can be taken:
1.buzz: Check whether the compressor fixing screws are loose and replace the shock absorber if necessary. If it is an old air conditioner, it is recommended to contact after-sales service to check the status of the compressor.
2.click: After turning off the power, check the fan blades for foreign matter or deformation, clean the dust or replace the blades.
3.sound of running water: This is a normal phenomenon of refrigerant flow, but if the sound is too loud, the pipe may be blocked and needs to be cleaned by professionals.
4.high-pitched howl: Motor bearing problems require professional maintenance, adding lubricating oil or replacing bearings in time.
5.Vibration sound: Reinforce the air conditioner bracket, check whether the installation is level, and add shock-proof materials if necessary.

4.Sound insulation treatment: The external machine can be equipped with a soundproof cover, and the internal machine can be positioned away from the head of the bed.
5.Choose a low-noise model: Pay attention to the noise parameters when purchasing (generally the internal unit is ≤40 decibels).
5. National standards for air conditioning noise
According to GB/T 7725-2004, the noise limits of air conditioners are as follows:
| Air conditioner type | Indoor unit noise limit (decibel) | Outdoor unit noise limit (decibel) |
|---|---|---|
| Refrigeration capacity ≤2.5kW | ≤40 | ≤52 |
| 2.5kW＜refrigeration capacity≤4.5kW | ≤45 | ≤55 |
| Refrigeration capacity＞4.5kW | ≤48 | ≤58 |
If the noise of your air conditioner exceeds the above standards, you can ask the manufacturer to return, exchange or repair it.
Summary:The problem of air conditioning noise cannot be ignored, as it affects the user experience and may indicate failure. Through the structured analysis of this article, you can quickly determine the source of noise and take appropriate measures. It is recommended to deal with minor problems by yourself, and contact professional maintenance in time for complex problems to ensure that the air conditioner operates efficiently and quietly.
