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 often your air filter has been replaced, to name a few—you may adjust your air duct cleaning more or less often. So, how can you find out 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 covered with dust or pet hair? Is there an obstruction in your cold air return vent? Are your registers wafting out dust? When you check 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 a smaller amount of airflow than others? If you answered “yes” to any of these questions, it’s probably time to ask Kilbourne Heating & AC in Delray Beach about air duct cleaning.
