A loud banging noise coming from your furnace is often the result of a problem with airflow in one way or another. When there’s too much positive pressure going through the ductwork, the metal the ducts are made of expands and makes that loud noise.

You could have furnace problems because of undersized ductwork, a dirty air filter, closed air vents or dampers or dirty ductwork. Most of these problems are a result of poor heating system maintenance.
