There are very big security risks. With more and more high-rise buildings, the installation position of air conditioners is getting higher and higher. However, in recent years, due to the disrepair of external air conditioners and the "old, weak and sick", there are more and more air crashes. What few people paid attention to before is that "aging" air conditioners have become "high-altitude bombs" hanging over people's heads, which may fall down and hurt people at any time.

In fact, it is not uncommon for air conditioners to fall off due to bracket corrosion. It can be said that there are thousands of "anti-aircraft guns" hanging overhead. On the 10 floor of a residential building in Yingtian Street, Nanjing, the air conditioning bracket was disconnected and the air conditioning machine outside collapsed. Fortunately, I didn't hit anyone. Outside a residential area on Nanhu Road in Nanjing, an air conditioner suddenly crashed downstairs. On the 7th floor of a residential building at Nanjing Central Gate and Yan Road, an air conditioner in the residential area hit a car.

The bracket should be repaired or replaced after 5 years of use. There is no mandatory specification whether the outdoor air conditioner is supported by a fixed platform or suspended in mid-air. It is basically decided by various air-conditioning manufacturers. "Zhao Hua, an air-conditioning installation master of a famous home appliance retail company in Jiangsu, said. It is reported that the external air-conditioning bracket was originally provided by air-conditioning manufacturers, and later it was mostly solved by after-sales installation enterprises or consumers. Therefore, in order to save costs, individual installation companies buy low-priced air-conditioning brackets, and it is difficult for users to guarantee the installation quality. Many small installation companies only process stents in some small factories. They make their own materials and specifications. There is no standard at all, leaving many hidden dangers.

"Most of the brackets used to place air conditioners are made of materials such as steel and pure iron. When exposed to sunlight and wind, they are sure to rust. " Master Zhou, who is engaged in air conditioning maintenance and sports, said that generally speaking, the service life of the bracket is 6-8 years. After the bracket has been used for more than 5 years, there are potential safety hazards, such as shaking and tilting. "Few people will ask us to replace the bracket." Master Zhou said that replacing the bracket does not belong to the scope of maintenance and needs to be paid, but this is not the main reason. "Most people don't have this awareness." It is best to regularly check whether the external air conditioning bracket is firm, not only to protect others, but also to protect yourself.
