I was pretty sure my dryer vent hadn’t been cleaned out since before I moved into my house. It was hard to tell, because the vent went up into the attic and out the rooftop, but the dryer performance seemed to be affected. Aspen came down on-time and took care of the problem. It must have been quite a clog! I feel much better now that they’ve taken care of something that could have been a fire hazard had I left it alone.
