When the air conditioner has poor cooling effect, many people will mistakenly think that the lack of fluoride is the main reason, and even become a common practice in the maintenance industry.
However, in fact, air conditioners usually do not need to add additional refrigerant without leaks.
Poor cooling effect may be caused by a variety of factors, such as dust accumulation on the filter screen caused by the air conditioner not being cleaned for a long time, voltage instability affecting the cooling effect, reducing the cooling efficiency due to the long steel pipe connecting the indoor unit and the outdoor unit, insufficient air conditioning power to cope with the environment of large spaces or multiple people, and the actual lack of fluorine.
When judging whether the air conditioner is deficient in fluorine, attention should be paid to whether the pipe joints of the external unit are wet and have oil, whether the compressor is operating normally, and whether the high-pressure pipe of the external unit is frosty.

If the above phenomenon occurs, it may be caused by fluoride deficiency. However, please note that fluoridation is dangerous and must be carried out by a professional.
Therefore, when the air conditioner is not cooling, we should not blindly add fluoride, but carefully analyze the cause and take appropriate solutions. At the same time, cleaning the air conditioner regularly to ensure that it is in good working condition is also an effective way to improve the cooling effect.
