How to Tell if Your Ducts Need to be Cleaned02/09/2017On 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, if you have pets, and how often your air filter has been replaced, 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 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 an obstruction within your cold air return vent? Are your registers carrying out dust? When you look 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 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 Patterson & Stirling Inc in Erie about air duct cleaning.
