I found Arizona Chimney and Air Ducts in the yellow pages. I think I may have used them years ago to clean my chimney. I never would have thought to call a place that cleaned chimneys to clean my dryer vents. The gentleman that cleaned my dryer vent did an excellent job. He arrived on time. He was very courteous and professional. A very nice man. I will probably be calling them again in a couple of years to clean my vents again. If I was not satisfied with a company then I would not recommend them to anyone. But, this company, I would absolutely recommend them for fireplace and or vent cleaning. They do a great job.
