What Is Duct Cleaning? (The Short Answer)

Air ducts are the network of metal or flexible tubes that distribute heated or cooled air throughout your home. Over time, dust, pet hair, construction debris, and biological contaminants accumulate inside these ducts. Duct cleaning physically removes this buildup so it's not recirculated every time your furnace or AC runs. It is different from changing an air filter — the filter catches airborne particles, but doesn't clean the duct walls themselves. (Serving Richmond Hill, Ontario.)
