How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Typically, 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, if you have pets, and how regularly your air filter has been replaced, to name some—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 absolutely 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 in your cold air return vent? Are your registers wafting out dust? When you check inside with a flashlight, can you see an accumulation 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 not as much airflow than others? If you answered “yes” to any of these questions, it’s most likely time to ask Olde Towne Heating & Air in Mount Pleasant about air duct cleaning.
