How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Typically, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Dependent on a lot of factors—like your home’s location, how many pets you have, and how often your air filter has been changed, to name some—you may need to have air duct cleaning more or less frequently. So, how can you tell for sure when it’s time to have your ducts cleaned? There are absolutely some significant signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there a blockage inside your cold air return vent? Are your registers carrying out dust? When you check inside with a flashlight, can you see an accumulation of debris or pet fur? Have insects or rodents made a home in your ductwork? Can you hear clatter other than your blower motor when you listen to the airflow? When your vents are fully opened, do any have a smaller amount of airflow than others? If you answered “yes” to any of these questions, it’s most likely time to ask Dave's Diversified Services in Front Royal about air duct cleaning.
