Original title: strange screams from the air conditioner. The professional maintenance of the air conditioner checked many times but found no problems
4hw.org now basically has an air conditioner in every household. Even if it's a rental house, it will install air conditioner for the tenants, because in the summer, it's hard to live without air conditioner. However, recently, Mr. Cai in Shanghai found that his air conditioner screamed strangely, and more than once, the professional maintenance of air conditioner did not find any problems.
As one of the household appliances, the air conditioner makes a strange noise in the middle of the night. It's really creepy that the strange noise happens, but no problem has been found out after checking by someone. This situation is making Mr. Cai, a Shanghai citizen, worried. According to Mr. Cai, the master bedroom of his family has a central air conditioner. For some reason, it always makes strange noises in the near future. The air conditioner makes strange screams, and it's still in the middle of the night.
For this reason, Mr. Cai also contacted the air conditioning installation unit, and the other party asked the air conditioning maintenance workers to check, but there was no problem. A few days ago, Mr. Cai recorded the eerie scream from the air conditioner in the middle of the night. It's not the first time that he listened roughly like the scream and listened carefully like the sharp metal friction. Subsequently, the reporter found a professional maintenance team to repair the door again, but the other side still did not check out any problems.
The reporter guessed that the strange screams from the air conditioner came from the top of the air conditioner. Would they have something to do with the upstairs residents? After the door-to-door inquiry, the reply was that they heard the sound at home. So the reporter immediately contacted the housing committee and the property management department. When the workers opened the air outlet of the air conditioner, they found a black circular solid falling out of the air conditioner, which gave us a clue. It turned out to be the excreta of rats. Later, the workers found the cause in the outdoor platform of Mr. Cai's home. The air conditioning interface, which was originally blocked by foam glue, had a gap suspected by rats.
After knowing the reason, the property also actively said that it would make corresponding protective materials according to the pipe diameter of Mr. Cai's house to prevent mice from entering again. At present, the property company has installed diamond net for the pipeline, and placed relevant mousetrap, similar to the previous sound no longer heard. Obviously, the strange scream from the air conditioner is not the cause of the air conditioner, and the professionals also remind that during the decoration of the house, especially when the pipeline is discharged, the property and the construction team should be contacted in advance to take relevant protective measures.
