After summer, can the dog days be far behind? Summer home air conditioning most often encountered problems, should not be refrigeration! Turn on the air conditioner and find that the air conditioner doesn't work. If you come to the maintenance master, you will be told: if you are short of fluorine, please give several hundred yuan for maintenance fee!
Be careful not to be fooled, the air conditioner does not blow cool air, it is not necessarily lack of fluorine! How to judge whether the air conditioner is really lack of fluorine? Let's have a look at the air conditioner pit prevention guide, and we won't be fooled again!
First step of pit Prevention Guide:
How to judge whether the air conditioner is lack of Freon?
Test whether the Freon pressure is normal. In summer, if the pointer on the detector is about 0.5-0.8, it is generally normal.
Second step of pit Prevention Guide:
How to judge whether the repairman has really filled you with fluorine?
If it is R410A refrigerant, when it is really filled with fluorine, the whole Freon tank must be inverted before the liquid can be injected in.
The third method of pit Prevention Guide:
The lack of refrigeration is not caused by lack of fluorine. What else may be the reason?
First look at the indoor unit, if the indoor unit does not appear error code, the air conditioning can also be started, it may be the problem of the outdoor unit.
If there is a problem with the accessories of the outdoor unit, the fan and compressor should not work. The air conditioning fan and compressor in the video above are in normal operation, indicating that it is not the problem of accessories.
If your air conditioner is a variable frequency air conditioner, the maintenance master said: there is a problem with the capacitor, you need to change the capacitor. Pay attention, it must be a pit for you!
Because of the reason that the air conditioner does not cool, it may also be that the condensing sheet of the outdoor unit has not been cleaned for a long time, and a lot of catkins and dust adhere to it, which leads to the problem of heat dissipation.
Therefore, the air conditioner under this reason wants normal refrigeration, only needs to carry on the deep cleaning of the air conditioner.
However, the general maintenance master will not give you to deal with, after all, how much cleaning price, maintenance price, this time you need to open your eyes to distinguish!
