Property demolition air conditioning

Editor: I once signed a purchase contract with a developer. The contract is a format clause provided by the developer, stating that the purchaser shall not install security doors and windows, air conditioners, clothes hangers, etc. Stick it on the external wall without authorization. But the developer didn't remind me of this content at that time, and I didn't care too much. Later, the developer entrusted a property company to be responsible for the property services in the early stage of the community. A week ago, I installed two air conditioners on the exterior wall of my house without harming the interests of other owners and endangering the safety of the house, but the property management company asked me to dismantle them on the grounds that I violated the agreement. And insisted that if I refused to dismantle it, I would bring a lawsuit to the court. Excuse me: is the reason for the property company established? Reader: Li Lili Reader: Although there is an agreement in the contract, the property management company has no right to ask you to dismantle the air conditioner. On the one hand, your behavior is not illegal.
