Should I be concerned about neighbour's incoming AC units
House on the right is my Victorian end of terrace. I have no windows on the wall, but I do have my front door (where the lantern is on the wall). My bedroom window and dining room window is next to where I am standing on the back of my house. My neighbours on the left side are having external AC units attached to the wall near the red switch. Should I be concerned? It might not look nice, but that's not up to me... but will it be noisy? Anything else I should know? Are there planning regs around where these things can go, etc.? Thanks!
