The air ducts in your HVAC system can easily become repositories for dust, particles, and even mold. It's generally recommended that your home's air ducts be cleaned every 3 to 5 years, but this is dependent upon the thoroughness of previous cleanings and your environment.
As this video explains, some homes can go 5 to 7 years between cleanings, especially if the previous appointment was performed very thoroughly by a professional duct cleaner. Indoor air quality tests can help identify sources of pollutants, and duct cleaning can help reduce any problems you and your family experience with allergies or respiratory issues. Homeowners can even help maintain clean ductwork by regularly cleaning carpets and vacuuming floor vents.
