What's the noise when the air conditioner is turned on? How much does it cost to repair
What's the reason for the loud voice of automobile air conditioner
1. When the amount of refrigerant added exceeds the standard, the load of the compressor will increase, resulting in the increase of load. You can look at the visit window of the air conditioner. When the air conditioner is opened, there is liquid flowing through the window, and there are a small amount of bubbles, indicating that the amount of fluorine is normal. If there are no bubbles, or if it is not normal, it means that too much refrigerant is added.
2. To check whether the added fluorine is the same as the original fluorine, if not, there will be air conditioning refrigeration problems. Now, the general refrigerant is R134a.
3. Check whether the tension of the lower compressor belt is normal. If it is too loose, tighten it. The possibility of belt over tightening is not very large.
4. The compressor bearing may be damaged. When the air conditioner is not turned on, the noise may not be obvious when the bearing operates by itself. However, after the air conditioner is turned on, the magnetic head and the bearing are sucked together to operate together, driving the internal work of the compressor, so that the noise may be greater when there is load. In this way, only replace the compressor bearing.
What's the matter with the loud air conditioning fan
1. The leaf of the exhaust fan in the air conditioner is deformed. It is recommended to replace the exhaust fan.
2. The motor of the exhaust fan in the air conditioner is damaged. It is recommended to replace the exhaust fan.
3. There is a lot of dirt in the air conditioner, which causes the fan blades to rotate inflexibly. It is recommended to clean the air conditioner.
How much does it cost to repair the car's air conditioner with loud voice
It depends on the specific failure. If the fluorine is added too much, it's better to put the fluorine. It doesn't cost any money. If the bearing of the compressor fails, it may take hundreds of thousands to replace the compressor, but it only takes hundreds to 200 to replace the bearing of the compressor. If it's a fan problem, it won't be very expensive, about 100 yuan.
