Dust, allergens, hair, dead skin cells, and other debris lives in your ductwork. Nothing you can do from the outside can prevent this build up so to mitigate the problem it's best to have your air duct system professionally cleaned, but how often? Every 1-3 years you should have your ducts cleaned to improve the air quality in your home.
