How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 On average, 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 regularly your air filter has been replaced, to name a few—you may need to have air duct cleaning more or less regularly. So, how can you tell for sure when it’s time to have your ducts cleaned? There are definitely some telltale signs when it’s time. Look for these clues: Are your cold air returns covered with dust or pet hair? Is there a blockage inside your cold air return vent? Are your registers carrying 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 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 probably time to ask Kowalski Heating, Cooling & Plumbing in McMurray about air duct cleaning.
