"Wow For the second time, in the last 7 or 8 years, I called upon Ottawa Duct Cleaning to clean my furnace ducts and I cannot reiterate enough how impressed I am with the crew and the work they performed in my house. I was really impressed and appreciative at the time that Roger spent with me explaining and walking me through the entire cleaning process. It is very clear what a difference it can make when you are dealing with professionals who know their job. I was also pleasantly surprised in the fact that the same crew members Marc and Derek were still with the firm and were just as pleasant and professional as their first visit. Hats off to you and your team Roger."
