Air conditioning perforation attribute is not allowed.

I am an air conditioner salesman. In fact, under normal circumstances, all air-conditioning companies will not help make holes now. The reason is that, on the one hand, it is more convenient for the decoration company because there are no professional hole diggers, so it should be included when signing a contract with them. On the other hand, air-conditioning sales don't all know that some special structures can't make holes or the size of holes can't exceed a certain range, in order to avoid responsibility. Therefore, the air-conditioning company should designate a location to remind the owners to ask about the property, and the decoration company is responsible for making holes. At present, many decoration companies are reluctant to make holes in order to get more money. If there were no professionals in the air-conditioning company, it would cost 30 to 50 yuan to make a hole. Decoration companies are professional. Remind the owner to pay attention to writing the air conditioning hole into the contract when signing the decoration company in the future.

In addition, the installation of the air inlet of central air conditioning needs to make holes in the ceiling, which should also be included in the renovation contract. The reason is simple: non-decoration companies can easily cause decoration damage, and other third parties should not make holes themselves.
