The dryer hasn’t been working properly for several years, and I’ve been putting up with it instead of getting the vent cleared out. I didn’t know until recently that most chimney sweep companies handle this service.
It’s a serious fire hazard. Most people don’t bother unless there’s a problem. This needs to be done annually and while the tech was here two of my neighbors, who’ve been here longer than I have, came by, got his card, and said they had never had their vents cleared out.
