Over time, dust, pet hair, construction debris and allergens collect in your ductwork and get blown back into the rooms you live in. Professional duct cleaning removes that build-up and can improve airflow, reduce dust on surfaces and help your furnace and air conditioner run more efficiently.
We use high-powered negative-pressure equipment and agitation tools to clean supply and return ducts, registers, and the furnace blower compartment. We also inspect ducts for disconnected joints and leaks — the kind of issues we fix every day on renovation projects like the one shown on this page.
