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. 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 handful—you may need to have air duct cleaning more or less regularly. So, how can you know for sure when it’s time to have your ducts cleaned? There are definitely some revealing 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 an accumulation of debris or pet fur? Have insects or rodents nestled 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 more than likely time to ask Air-Dynamics Inc in San Angelo about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are a couple things you can do to help keep your ducts cleaner and extend the timeline between expert cleanings. First and foremost, arrange annual HVAC maintenance with the professionals at Air-Dynamics Inc. A maintenance check of your furnace each fall and your AC each spring, which should include inspection, and potential replacement, of your air filter, will help keep your HVAC system operating effectively, and should help keep your ducts clean. You can also chat with the team at Air-Dynamics Inc about installing an air purification system. We offer the Lennox PureAir Air Purification System, Healthy Climate Carbon Clean 16 Media Air Cleaner, Healthy Climate 11 Media Air Cleaner, Healthy Climate High-Efficiency Particulate Air (HEPA) Filtration System and Healthy Climate UV Germicidal Lights. Other actions you can take include: Regularly dusting and vacuuming your home. Checking your air filters routinely and exchanging them when the manufacturer recommends changing them. Most filters will show dust on them after a short time in service, but they may not demand changing. Sealing leaks in air ducts that permit dust to enter from areas like your attic. Replacing poor or damaged air-duct insulation. With a professional air duct cleaning and some proactive measures, you can help keep the air in your San Angelo home clean and healthy.
