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. Contingent on a lot of factors—like your home’s location, whether or not you have pets, and how often your air filter has been changed, to name a handful—you may need to have air duct cleaning more or less often. So, how can you know 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 blowing out dust? When you gaze inside with a flashlight, can you see a collection of debris or pet fur? Have insects or rodents nestled 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 probably time to ask WM J Kraus & Son in Keokuk about air duct cleaning.
