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. Depending 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 handful—you may require 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 significant signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there a blockage in your cold air return vent? Are your registers wafting 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 noise 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 most likely time to ask Stanford Heating & Cooling in Bloomfield about air duct cleaning.
