It's a bit iffy if it's a rented house.
I think we should talk to the owner's house well, but anyway, we have a lot of air conditioning installed these days, so we might need the owner's house.

When there is a wall between the air conditioner indoor unit and the outdoor unit, it is to pierce the wall.
It's also used in terms of core work, wall drilling, wall drilling.
After the hole is opened, silicon is used to seal the empty space.
