I have two big dogs and decided that I should clean my duct professionally. Normally I do it myself but since we were expecting our 1st baby. The best thing was to hire someone to do it. A friend recommended them. I called them and booked an appointment to clean my ducts and inspect my gas furnace. They arrived at the time they were supposed to. The work was done effectively at a competitive price. I would not hesitate to hire them next time.
