Air ducts are the pathways that run throughout your house or office space as they take treated air from your heating and cooling systems and circulate it through your rooms. Unfortunately, this air can pick up dirt, dust, and other pathogens in your ductwork that will soon be distributed through the vents in your house or office. The filtration systems found in most heating and cooling systems filter a portion of your indoor air before redistributing it. This air has to travel through your ductwork before it reaches you and, because allergens, pollen, dirt, mold, and other pathogens collect in your ducts over time, cleaning them is very important. While it’s best to schedule professional duct cleaning services on a regular basis, you can also help maintain your ductwork on your own.
