So the guy that I bought my house from set up his exhaust in a really awkward place for cleaning. I can clean the bottom of the pipe from below by taking the cap off and using a brush. But I can't really get to the top horizontal section. He put it right underneath the AC unit. So when I put a ladder up it's too far to reach. Does anybody have any good ideas about how to clean this horizontal pipe? Is the only way to clean from the inside by taking the pipe apart?
