I had a good experience with Arizona Chimney & Air Ducts when I called them in. I had a new dryer in my house, less than a year old. Which is why I couldn't imagine why it was always showing that there was something wrong with the ducts. That's why I called in Arizona Chimney & Air Ducts. The guy came in and he went up on the roof. And I was totally surprised when he came back with a large back full of lint! He said that the duct was almost 80% full. I thought their rate was on the expensive side, but I had no idea how full it was and I certainly didn't want a fire. It was a good thing I called them. They were polite, friendly and professional in the work and since then, everything has been working well.
