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, how many pets you have, and how often your air filter has been swapped out, to name some—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 significant signs when it’s time. Look for these clues: Are your cold air returns caked with dust or pet hair? Is there a jam inside your cold air return vent? Are your registers carrying out dust? When you look inside with a flashlight, can you see an accumulation of debris or pet fur? Have insects or rodents found shelter 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 most likely time to ask B & B Heating & Cooling in Florissant about air duct cleaning.
