Why is the air conditioner not cold?
Recently, air conditioning not cooling has become one of the hot topics in summer. As the temperature rises, many users report that the air conditioner has poor cooling effect or even no cooling at all. This article will combine the hot content of the entire network in the past 10 days to analyze the reasons, solutions and precautions for air conditioners that are not cold, and provide structured data for reference.
1. Common reasons why air conditioners are not cooling
| Cause classification | Specific performance | Proportion (whole network statistics) |
|---|---|---|
| Insufficient refrigerant | There is abnormal noise during operation, the air output is normal but the temperature is high. | 38% |
| Filter clogged | The air volume is significantly reduced and energy consumption is increased. | 25% |
| Outdoor machine failure | Compressor does not start or stops frequently | 18% |
| Thermostat problem | There is a big difference between the displayed temperature and the actual temperature | 12% |
| Improper installation | Newly installed air conditioner has uneven cooling | 7% |
2. User self-examination steps
According to the hot discussions on the home appliance repair forum, it is recommended to check in the following order:
1.basic check: Confirm that the power connection is normal, the remote control battery has sufficient power, and the mode is set to "cooling" instead of "dehumidification" or "air supply".
2.Filter cleaning: Take out the filter, clean it with a soft brush, dry it and put it back (about 90% of filter problems can be solved by yourself).
3.Observe the outdoor unit: Check whether the outdoor fan is running and listen to whether there is any working sound from the compressor. If the outdoor unit is severely frosted, it must be stopped immediately.
4.Temperature test: Use a thermometer to measure the air outlet temperature. The normal value should be between 8-12°C (more than 10°C difference from the ambient temperature).
3. Maintenance service market data
| Service type | Average quote (yuan) | Peak service hours |
|---|---|---|
| Fluoride service | 150-300 | 14:00-18:00 |
| deep cleaning | 80-120 | 9:00-11:00 |
| Circuit maintenance | 200-500 | Reservation required |
| Compressor replacement | 800-2000 | Need to return to factory for repair |
4. Preventive maintenance suggestions
1.seasonal maintenance: The filter should be cleaned before use in summer, and the power should be cut off and covered with a dust cover when not in use for a long time in winter.
2.Usage habits: Avoid frequent power on and off, and the set temperature is recommended to be no less than 26°C, which can save more than 30% of energy consumption.
3.Professional maintenance: Professionals are required to clean the evaporator and condenser every 2-3 years. For older models, it is recommended to check the circuit insulation.
5. Consumer Rights Reminder
Recent complaint platform data shows that the following chaos exists in air-conditioning maintenance:
- False fluoridation (accounting for 42% of complaints)
- Minor illness overhaul (35%)
- Working without a certificate (23%)
It is recommended to choose the official after-sales service provider of the manufacturer or a service provider that holds the "Practice Qualification Certificate for Home Appliance Repair Industry". After repair, be sure to ask for a receipt and indicate the warranty period.
From the above structured analysis, it can be seen that most problems of air conditioning not cooling can be solved through basic maintenance. If you encounter a complex fault, you should contact a professional agency to handle it in time to avoid damage caused by improper operation. Proper use and regular maintenance can significantly extend the service life of air conditioners and ensure a cool summer.
