C-Thru Duct & Furnace Cleaning/Hot Water Pressure Washing was founded in July 2002. We use either a high powered portable unit (Abatement Technologies) or our truck-mount unit for duct cleaning. Located on Hartzel Road in St. Catharines, we are a sublet contract for Home Depot and the Bay, as per their requests. We have regular contracts with hotels and theatres, and a loyal and increasing yearly customer base. As a certified Coleman and York dealer, we also sell, service and install residential and commercial furnaces and AC units. We also specialize in personalized projects and special orders. Our hot water pressure washer is available to clean your commercial and residential windows, bricks, siding and driveways. Contact us for more information.
