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. Dependent on a lot of factors—like your home’s location, if you have pets, and how often your air filter has been swapped out, to name a few—you may adjust your air duct cleaning more or less frequently. So, how can you know for sure when it’s time to have your ducts cleaned? There are absolutely some revealing signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there a jam in your cold air return vent? Are your registers wafting out dust? When you look inside with a flashlight, can you see a collection 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 not as much airflow than others? If you answered “yes” to any of these questions, it’s most likely time to ask All Seasons Heating & A/C Co in Bloomington about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are a few things you can do to help keep your ducts cleaner and lengthen the timeline between specialized cleanings.
