The guys from Tri-County Aire were very polite. They did their work. They cleaned up after themselves and they did an excellent job. They really went out of their way to clean my dryer duct. This was my first time working with Tri-County, but I would use their service again. I can't recall their names, but the guys who did the work did a very good job. When we asked them to do something they did it. They pulled the dryer out and put it back in exactly the right place. I was happy with their service. The pricing was OK, but I wish it could have been a bit cheaper.
