Dr. Duct is a family-owned and operated business that has been serving the Ottawa region for over a decade. We set ourselves apart by providing first class service, and treating every home and business as our own. Call us today for air duct cleaning, dryer vent cleaning, central vacuum cleaning, and more! I had great experience with these guys. Came on time, put a lot of effort and attention to detail. Their price was 30% cheaper than their competitors (they had a promo at that time). As it turned out a lot of the HVAC companies in Ottawa re-sell third party duct cleaning services..
