Coleman Lantern 17B, want to replace "window"/wall AC with mini split.
I am in the process of replacing my ac with a mini split. I have determined that a bumper mount is the best spot for the outdoor unit and will be ordering bumper brackets and a strong mount to secure the outside positioning. I am going to put the inside unit over where the AC is now. I am wondering what the best route would be to run the copper lines to the indoor unit and what all of your experience is with running cabling along the exterior wall, dealing with studs and that sort of thing.
