5. Professional advice
1.New machine installation acceptance: National standards stipulate that the indoor unit noise of an air conditioner with a cooling capacity ≤ 4500W should be ≤ 45 decibels and the outdoor unit ≤ 55 decibels. It is recommended to use the mobile phone decibel meter APP for preliminary testing after installation.
2.Regular maintenance cycle:
| parts | Maintenance frequency |
|---|---|
| filter | monthly cleaning |
| condenser | 1 time per year |
| Circuit check | Once every 2 years |
3.Rights protection precautions: Keep the purchase certificate and noise test report (which needs to be issued by the CMA certification agency), and you can request repair, replacement or return according to Article 40 of the "Product Quality Law".
6. Technology development trends
Recent industry trends show that the silent technologies launched by mainstream brands in 2023 will mainly focus on:
- Inverter compressor noise reduction design (average reduction of 6-8 decibels)
- Optimization of bionic air duct structure
- Intelligent night silent mode (automatically limits the maximum wind speed)
From the above analysis, it can be seen that the air-conditioning noise problem requires targeted measures based on specific causes. It is recommended that users give priority to troubleshooting installation problems and filter cleaning. If they still cannot solve the problem, they should contact professional after-sales service in time.
