this company did a fantastic job on our ducts and dryer. I was informed when they came out that dirty dryer is the leading cause of fires in homes. They checked and showed me that the dryer needed to be cleaned. I've never seen so much stuff come out of a dryer in my life! As for the ducts- they showed me before and after photos and consulted me on what they were doing. the sales tec on the phone was very knowledgeable and thorough and didnt mind me asking tons of questions. they were great with my kids and the nosey dog. lol i have reccomended them to freiends and family, and as of this review, three family members have had them come out and say it was satisfactory work. very honest guys, couldn't be happier. thanks!
