Can I close vents to deflect air?

• <div><p>No, because closing air vents could damage your HVAC system. Closing a vent will only keep the air in the duct, not redirect it to a room or zone where you’d prefer it to be. That air will become trapped within your ductwork, creating a buildup of pressure that can damage the ducts and cause leaks. </p></div>

What if the mold and mildew smell won’t go away?

• <div><p>After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To <a href="https://www.angi.com/articles/get-rid-musty-smells-in-house.htm">get rid of a mold smell</a>, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area.
