There are several signs that your air ducts may need cleaning. One of the most noticeable signs is a decrease in air quality or an increase in dust, dirt, or debris around the home. If you notice a musty or moldy odor coming from your vents, it could indicate that moisture is trapped inside the ducts, which may lead to mold growth. Another sign is uneven airflow or rooms that feel stuffy or not as cool or warm as others, suggesting blockages or dirt buildup in the ducts. If your energy bills have risen unexpectedly, clogged ducts can cause your HVAC system to work harder, reducing efficiency. Finally, frequent allergy flare-ups or respiratory issues among household members might be linked to the buildup of dust, pollen, or other contaminants in your air ducts. If you notice any of these signs, it’s a good idea to have your air ducts inspected and cleaned by a professional.
