Hello everyone! A couple of days ago I noticed that my dryer was running longer than usual and drying clothes less efficiently. I realized that the ventilation duct might be clogged, but I'm not sure if I should try to clean it myself. How realistic is it to do it yourself? And if it's better to trust the professionals, who would you recommend? I want to be sure that the work will be done efficiently and safely.
