The door guy is telling be that the spring on the conventional overhead door is the limiting factor and why I can't notch for the AC. The door itself will clear once its fully horizontal. - lets think out side the box.. what if I did away with the whole spring mechanism and used a 12V ATV type winch to pull the door up ( through a pulley system)and also control the door on the way down. I figure the only place it would bind would be when the door is all the way down and mostly vert. I could remedy this by not going all the way down so that the top panel has already started to break-over. I could add a 2x6 at the bottom as a filler piece? This will not be a daily open and close stall - maybe monthly.. All the other options stated have be explored except cut concrete and I don't know how much thickness there is to cut?
