Could duct cleaning help my family's coughs?« Back to Previous Page

After the heavy dust storms we had last month, I noticed a strong musty smell lingering in my bedroom. The windowsills are all coated with a layer of fine dust, even though I cleaned them just two weeks ago. My wife and kids have been complaining about persistent coughs too, especially at night. How urgent is it to clean the ducts in my apartment, and could this be causing their health issues?
