Does the central air conditioner need to be approved for moving?

Air conditioning drilling is generally to inform the property and get approval before construction. After all, most air conditioning openings are made on the load-bearing wall, which is easy to destroy the structure of the load-bearing wall and will do harm to the load-bearing of the whole building. Therefore, you must inform the property before drilling to confirm safety.

How many holes need to be drilled to install the central air conditioner. If it is an on-hook air conditioner, it usually needs three holes. Two holes are used to hang the indoor unit of the air conditioner on the wall, and the other is the pipeline route connecting the indoor unit and the outdoor unit of the air conditioner. If it's just a cabinet air conditioner, just make a hole to connect the internal and external machines. Generally speaking, an external machine smaller than 2P or 60kg has 4 holes, and an external machine larger than 2P or 60kg has 6 holes.
