I appreciate how thorough and professional Advance Dryer Vent Cleaning was. Evan came to clean my dryer vent which, to my surprise, was nearly a fire hazard due to the build up of lint from all of the laundry I do. Evan explained that he used a Vent Vision camera to see inside the dryer vent. This technology allowed him to have a clearer picture of what was happening inside my dryer vent and thoroughly clean it without leaving anything behind. He was professional, punctual, and all-around helpful and willing to answer my questions. I would recommend this company to anyone and know that I will use them regularly to clean my dryer vent.
