How to Tell if Your Ducts Need to be Cleaned Posted February 9, 2017 Generally, 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 swapped out, to name a few—you may need to have air duct cleaning more or less often. So, how can you tell 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 caked with dust or pet hair? Is there a jam inside your cold air return vent? Are your registers carrying 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 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 most likely time to ask B & B Heating & Cooling in Florissant about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are a few things you can do to help keep your ducts cleaner and lengthen the timeline between specialized cleanings. First and foremost, setup routine HVAC maintenance with the specialists at B & B Heating & Cooling. A maintenance check of your furnace each fall and your AC each spring, which should include inspection, and possible replacement, of your air filter, will help keep your HVAC system functioning efficiently, and may help keep your ducts clean. You can also talk to the team at B & B Heating & Cooling about installing an air purification system. We provide 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: Consistently dusting and vacuuming your home. Examining your air filters habitually and changing them when the manufacturer recommends changing them. Most filters will present dust on them after a short period in service, but they may not require replacement. Sealing leaks in air ducts that permit dust to come in from areas like your attic. Replacing poor or damaged air-duct insulation. With a specialized air duct cleaning and some proactive measures, you can help keep the air in your Florissant home clean and healthy.
