How to Tell if Your Ducts Need to be Cleaned02/09/2017On 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, how many pets you have, and how frequently your air filter has been changed, to name a few—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 telltale signs when it’s time. Look for these clues: Are your cold air returns coated with dust or pet hair? Is there an obstruction in your cold air return vent? Are your registers blowing out dust? When you gaze 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 clatter 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 Northglenn Heating & Air Conditioning, Inc. in Denver about air duct cleaning.
