I think it is more geared towards the central a/c units. I have taken coolers from the window units to one of my yards, and other than getting my license number and a photo, I do not have a problem. I do have a cooler from central unit that I am hanging on to that a guy asked me to pick up until I can figure out what to do with it. I am planning on getting my license to evac, and I am hoping that will suffice.
