The bedroom split air conditioner gets it's power cable from the switches in the kitchen and goes under the tile floor to the bedroom. Problem is, it leads to an old switch fuse box thing that is far away from where the air conditioner. So previous occupants resorted to routing the cable from the outside in. So it starts from kitchen to bedroom then to outside then to bedroom again to connect to AC unit.
I asked electricians and they said to do it so it doesn't go outside, would be to tear up tiled floor. I asked for another way and he couldn't see an alternative because there is a beam through the wall that sits between the AC power source connection and the AC.
