Should I worry about mold in the ducts?« Back to Previous Page

After the rain last month, I noticed a slight musty odor coming from the ducts in our bedroom. The AC filter is clean, but the smell persists even when no one is using the air conditioning. My family has been complaining of mild coughing and sneezing recently too. Should I be concerned about mold or allergens in the ductwork?
