Why is the air conditioner not blowing cold air? Analysis of hot topics on the Internet in the past 10 days
Recently, as the high temperatures in summer continue, the problem of air conditioners not cooling has become a hot topic on the Internet. Many users reported that the air conditioner suddenly stopped blowing cold air, affecting their living comfort. This article combines the hot topics on the Internet in the past 10 days to provide you with a systematic analysis of the reasons and solutions for why the air conditioner is not cooling.
1. Common reasons why air conditioners are not cooling
| Ranking | Cause classification | Specific performance | frequency of occurrence |
|---|---|---|---|
| 1 | Refrigerant leak | The copper tubes of the outdoor unit are frosted and the cooling effect gradually deteriorates. | 35% |
| 2 | Filter clogged | The air output is small and the internal unit makes abnormal noise. | 28% |
| 3 | Outdoor machine failure | The compressor does not start and the outdoor fan does not rotate. | 20% |
| 4 | Thermostat problem | The displayed temperature is inconsistent with the actual temperature and starts and stops frequently. | 12% |
| 5 | The power supply voltage is unstable | Air conditioner shuts down intermittently and display flashes | 5% |
2. Recent hot cases in social media
The Weibo topic #热播精品自产拍# has been read 120 million times, and the related short video on Douyin has been played more than 80 million times. The following cases triggered widespread discussion:
| platform | Typical cases | Solution | Interaction volume |
|---|---|---|---|
| Tik Tok | User "Air Conditioning Brother" demonstrates filter cleaning | Cooling resumes after removing and washing the filter by yourself | Like 45.6w |
| little red book | "The air conditioner suddenly stopped cooling" help thread | After-sales inspection showed insufficient refrigerant. | Collection 2.3w |
| Station B | UP owner actually measured the maintenance costs of different brands | Comparison of after-sales costs of 6 major brands | Barrage 1.8w |
3. Step-by-step troubleshooting guide
1.basic check: Confirm that the air conditioning mode is set to "cooling", the temperature is set lower than room temperature, and the fan speed is adjusted to medium to high.
2.Filter cleaning: After turning off the power, take out the filter, clean it with a soft brush and clean water, dry it and put it back.
3.External machine inspection: Observe whether the outdoor fan is running, listen to whether there is any working sound from the compressor, and pay attention to whether the surrounding cooling space is sufficient.
4.Professional testing: If the above method does not work, it is recommended to contact professional after-sales service and focus on checking:
| Test items | normal value | abnormal behavior |
|---|---|---|
| Refrigerant pressure | 4-6kg/cm² | If the pressure is too low, the leakage needs to be repaired and fluoride added. |
| Working current | Rated value±10% | Excessive current may cause compressor failure. |
| Air outlet temperature difference | 8-15℃ | Temperature difference is less than 8℃, insufficient cooling |
4. Preventive maintenance suggestions
1.Regular maintenance: Clean the filter before use every year, and do a deep cleaning every 2-3 years.
2.Correct use: Avoid frequent power on and off, and set the temperature not lower than 26°C to save energy.
3.voltage stability: Use a voltage stabilizer to solve the problem of voltage instability and extend the life of the compressor.
4.Shopping advice: When purchasing a new air conditioner, pay attention to the energy efficiency ratio (APF). First-class energy efficiency products have higher cooling efficiency.
5. Consumer Rights Protection Reminder
Recent complaint platform data shows that the following chaos exists in air-conditioning maintenance:
| Complaint type | Proportion | coping strategies |
|---|---|---|
| False fluoridation | 42% | Request to see pressure gauge data |
| minor illness overhaul | 35% | Get a written test report |
| Unreasonable charges for accessories | twenty three% | Check the price of accessories on the official website |
Through the above system analysis, when encountering the problem of air conditioner not cooling, consumers can troubleshoot according to the steps. It is possible to solve simple faults by themselves, and to effectively protect their rights when professional services are needed. It is recommended to save this article for future reference.
