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 often your air filter has been changed, to name a few—you may adjust your air duct cleaning more or less frequently. So, how can you find out for sure when it’s time to have your ducts cleaned? There are absolutely 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 inside your cold air return vent? Are your registers wafting out dust? When you check 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 Davis Heating & Air Conditioning in Rocky Mount about air duct cleaning.
