How long does it take to add fluoride to the air conditioner?

Generally speaking, air conditioners need to be fluoridated after being used for more than five years. The refrigerant of general air conditioner can be used for five years. When it is found that the refrigeration effect of the air conditioner is getting worse and worse, it means that there is less and less refrigerant in the air conditioner. Fluorine will be added at this time. But there are also air conditioners that have been useless for more than five years and need to be added with freon. Generally, in summer, if there is something wrong with the low-pressure pipe at the connection point of the outdoor unit of the air conditioner, it will not condense or refrigerate, and the air blown out by the outdoor unit of the air conditioner is not hot, and the pressure is lower than 0.4, which indicates that there is something wrong with the air conditioner. If the outside machine does not blow hot air, the inside machine freezes and blows fog, indicating that the air conditioner needs fluorination. And if in winter, the thick pipe of the air-conditioning interface is at room temperature and not so hot, it also means that fluoride needs to be added. In addition, when the air conditioner leaks, or because it has been used for a long time, it has been moved many times, resulting in excessive consumption of freon, and the air conditioner should also be fluoridated. The sudden shutdown of the air conditioner after starting may also be caused by insufficient freon, indicating the need to add fluoride. When adding fluoride to the air conditioner, be careful not to add too much at a time, just the right amount. If you are not sure, don't add fluoride without authorization, just contact the property.
