How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Generally, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Depending on a lot of factors—like your home’s location, how many pets you have, and how frequently your air filter has been changed, to name a handful—you may require air duct cleaning more or less often. So, how can you tell for sure when it’s time to have your ducts cleaned? There are definitely some significant signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there an obstruction in your cold air return vent? Are your registers carrying out dust? When you gaze inside with a flashlight, can you see a buildup of debris or pet fur? Have insects or rodents made a home in your ductwork? Can you hear sound other than your blower motor when you listen to the airflow? When your vents are fully opened, do any have not as much airflow than others? If you answered “yes” to any of these questions, it’s most likely time to ask PWA Heating & Cooling Inc in Plainfield about air duct cleaning.
