We are very happy with the service we got from AZ Chimney Sweep.
Some background: The Sears tech who checked my electric dryer said the flow of air from the dryer vent was poor. I had not noticed any problem but wanted to be sure. Instead of using Sears for vent cleaning I decided to go with AZ Chimney due to their many positive Yelp reviews. I was able to get an appt the next day.. The service tech called ahead when he was enroute. Sean is a nice young man, professional and pleasant.
He was up on the roof using a huge vacuum device cleaning out the vent. I could hear what sounded like gravel being sucked up. Sean did a couple of extra things too. Shortened the dryer vent hose which was too long. Raised the cap on the roof vent a bit. Both of these would help make dryer venting more effective. I'm a satisfied customer.
