You diligently clean your house daily or weekly as needed, perhaps also doing big cleaning projects twice a year. This is all well and good, but do you give your home's infrastructure a regular cleaning? Your heating and cooling air ducts should also be inspected and cleaned on a regular basis. If you've been in your home for a while and have never had your air ducts inspected, it may be time to do so. After all, the air that flows around your home affects your health as much as dirt and grime buildup!
The federal Environmental Protection Agency (EPA) recommends that a professional heating and cooling contractor inspect your home's air ducts and heating and cooling systems. If the contractor sees signs of mold, dust, dirt, and other contaminants, or if he or she notices a musty odor in the ductwork, having your ducts and systems cleaned will be recommended. If that's the case, you should consider hiring a professional duct cleaner -- this is probably not a job you can safely do on your own.
