Could ductwork cause our humidity issues?« Back to Previous Page

After the rain last month, I noticed a lingering damp smell in the hallway near my bedroom. My daughter has been complaining of a persistent dry cough and my son seems to be having more frequent asthma attacks. Given that our apartment is on the second floor, we rarely get much water intrusion, but this humidity issue feels strange. Could it be related to the ductwork? What signs should I look for to determine if we need professional duct cleaning?
