1. Common reasons why air conditioners are not cooling
According to the entire Internet search and user feedback, the reasons why the air conditioner does not cool are mainly concentrated in the following aspects:
| Reason | Specific performance | solution |
|---|---|---|
| Insufficient refrigerant | The air conditioner is running but the cooling effect is poor and the air outlet temperature is high. | Contact a professional to add refrigerant |
| Filter clogged | The air output is small and the cooling efficiency decreases. | Clean or replace filters regularly |
| Outdoor unit failure | The outdoor unit does not operate or the noise is abnormal | Check the power supply, fan or contact maintenance |
| Improper temperature setting | The set temperature is too high and the cooling effect is not obvious. | Adjust to a reasonable temperature (recommended around 26°C) |
