I am a very satisfied customer! Vern and Steve arrived on time, were very courteous and very knowledgeable. Vern took extra time to explain what he was doing and why, which I appreciated, and I felt that he was treating my duct cleaning as he would doing a duct cleaning in his own home. This is the icing on the cake for me. As I have an allergy to dust, I am confident I will breathe easier and sleep better tonight!
