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, whether or not you have pets, and how regularly your air filter has been swapped out, to name a handful—you may require air duct cleaning more or less regularly. So, how can you know for sure when it’s time to have your ducts cleaned? There are certainly some telltale signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there an obstruction in your cold air return vent? Are your registers wafting out dust? When you look inside with a flashlight, can you see a buildup of debris or pet fur? Have insects or rodents found shelter 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 less airflow than others? If you answered “yes” to any of these questions, it’s more than likely time to ask Alan Heating Air Conditioning, Inc. in Elmhurst about air duct cleaning.
