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, whether or not you have pets, and how often your air filter has been replaced, to name a handful—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 definitely 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 wafting out dust? When you check 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 not as much airflow than others? If you answered “yes” to any of these questions, it’s more than likely time to ask Guidry's Air Conditioning & Refrigeration Service in Raceland about air duct cleaning. Prolonging Time Between Air Duct Cleaning There are some things you can do to help keep your ducts cleaner and extend the amount of time between specialized cleanings. First and foremost, setup routine HVAC maintenance with the professionals at Guidry's Air Conditioning & Refrigeration Service. A tune-up of your furnace each fall and your AC each spring, which should consist of inspection, and prospective replacement, of your air filter, will help keep your HVAC system operating effectively, and may help keep your ducts clean. You can also talk to the team at Guidry's Air Conditioning & Refrigeration Service about installing an air purification system. We have 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 steps you can take include: Regularly dusting and vacuuming your home. Examining your air filters habitually and changing them when the manufacturer recommends exchanging them. Most filters will display dust on them after a short time in service, but they may not need exchanging. Sealing leaks in air ducts that permit dust to come in from areas like your attic. Exchanging poor or damaged air-duct insulation. With a professional air duct cleaning and some proactive measures, you can help keep the air in your Raceland home clean and healthy.
