Is it illegal to put someone else s air conditioner outside the unit in the balcony of the house?

You follow a principle, that is, the outdoor unit is to exchange heat with the outside, which means to transfer the heat from the house to the outside of the house. At the same time, you also need to consider whether the ventilation in your balcony is smooth, otherwise it will affect the heat exchange effect, cooling in summer and heating in winter.

There will be problems. Enclosures may resonate, reduce heat exchange efficiency, and may shut down due to poor exchange during extreme high temperatures. It is recommended that the balcony should be sealed outside the relocation room.

With such installation, heat dissipation will definitely be a problem, the air conditioner is prone to failure, and the noise is loud. It is recommended to move out,

Yes, it's fine! The outdoor unit is pressed outside the house mainly to facilitate the drainage of water pipes, and the outdoor unit is too loud when it is running, so these two problems will be fine.

The source of noise is because of the rotation of the fan and the vibration of the parts, and the sound of the fan rotation is not easy to handle, which is determined by the machine itself; Vibration-induced noise can be done using some rigid foam pads underneath, like a cushion, which you can try.
