I called Company PA DRYER VENT CLEANING to clean my dryer vent, which was clogged after a light came on in the dryer. A person came to my house, removed my dryer, and cleaned it all the way to the outside. Then he showed me all the lint and debris that came out. The price was reasonable. I will call next week for an appointment to clean my air ducts. I saw all the videos online, and they do a great job. I highly recommend everyone who needs service to call them.
