I was told that the duct cleaning specialist would arrive at my home between 1-3 pm, They arrives at 1:15 Paul Barret came in with a partner to assist him. They were friendly and explained the process in cleaning my Ducts. They took extra care to make sure nothing was damaged and not to create any extra dust in my home. They showed me before and after pictures of my air ducts, and what a difference, it made, as I had not done them for ten years prior. I highly recommend their service, as they are very professional and do and excellent job. And will definitely use them again in the future, and not leave so long as before. Was informed it should be done every four years. Thanks for a great job. john Patryluk
