How to Tell if Your Ducts Need to be Cleaned02/09/2017Generally, air ducts need to be cleaned every three to five years according to the National Air Duct Cleaners Association. Contingent on a lot of factors—like your home’s location, if you have pets, and how regularly your air filter has been swapped out, to name a handful—you may require air duct cleaning more or less frequently. So, how can you tell 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 caked with dust or pet hair? Is there an obstruction within your cold air return vent? Are your registers blowing out dust? When you gaze inside with a flashlight, can you see a buildup 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 not as much airflow than others? If you answered “yes” to any of these questions, it’s more than likely time to ask B & G HVAC in Marshalltown about air duct cleaning.
