My wife and I bought our house a year ago. Visually the portions of the duct work that I could see were dirty. After a new furnace and A/C install, I was referred to Ductworks for cleaning. I could not be happier with the outcome. The technician, Felipe, was on-time, courteous, and professional. He explained everything that he was going to do and the approximate time it would take before beginning work. Felipe, worked hard throughout the day and was respectful of our home and our time. At each step he filled me in with where he was at in the process and how much longer he thought it would take. At the end the work, Felipe was able to show me before and after pictures of the ducts went over his entire process. I really couldn't be happier with the service.
