As the temperature rose, it was at the peak of the use of central air-conditioning in Hefei. Usually, many users will encounter many problems during this period, many of which are the central air-conditioning suddenly not cooling or cooling effect is relatively poor, some maintenance staff said they need to add fluoride. Mr. Wang, who lives in Hefei, Anhui Province, opened the "dust-seal" air conditioner for more than half a year and suddenly discovered that the cold wind blowing out was "not to force." Mr. Wang immediately got an appliance repairman from the Internet. After a simple "diagnosis," the other person said "Need to add Freon." After the maintenance staff tossed and collected 160 yuan of fluoridation fees, Mr. Wang found that the air conditioning seemed to be "healed." However, less than a month later, air conditioning began to “make it happen†again. This time, Mr. Wang got a professional central air-conditioning installation and maintenance personnel from Anhui Yinliyuan through a friend. “He checked the inside and outside machines and said that it was the poor cooling caused by the central air-conditioning's heat dissipation. It was not related to the addition of fluorine. He gave the floor. After a bit of cleaning, the central air-conditioning returned to normal and there is no problem until now.†Mr. Wang felt angry about the “flicker†last time.
