Check out the before and after results for one of our dryer vent cleaning appointments in Potomac, MD. The before image shows inside the dryer where the lint had already combusted. The dryer had a very strong burning odor like bread burning in the toaster. It was not drying since lint clogged the piping. Luckily, we were able to clean it out before it became a dangerous fire hazard for the homeowner. For your dryer vent or duct cleaning, contact Quality Air Solutions at (301) 388-3919.
