Fall Air Duct Cleaning – Is It Necessary?

Have you ever noticed that the crisp fall air seems to bring about persistent sneezing, coughing or wheezing? Have you ever thought that you or a loved one must be allergic to something that only grows in the fall? Have you ever known anyone with asthma that seems to have more attacks or use their inhaler more frequently during the fall and winter months? Contrary to popular belief, this phenomenon may not be caused by allergens that are growing outside. It may actually be caused by something that is growing in your own home.

The cooler temperatures of fall and winter send people indoors away from outdoor pollen’s but straight into the grasp of dust mites, animal dander, fungi, bacteria and mold spores. According to the American College of Allergy, Asthma and Immunology, as many as 10 percent of the population and 90 percent of people with allergic asthma are sensitive to dust mites. According to the National Air Duct Cleaners Association (NADCA) an average 6 room home can collect 40 pounds of dirt, dust and allergens in the air ducts each year. The contaminants build up in air ducts and are then blown out for us to breathe using our forced air heating and cooling systems. Healthy Buildings International has sited that a major factor contributing to Sick Building Syndrome is dirty ventilation systems and contaminated air ducts.
 
Unlean ductwork can also produce a variety of other things into the air in your home such as insulation, rodent droppings,and pet fur. An article in the Las Vegas Review Journal states that an estimated 90 percent of HVAC older than 10 years old will actually have some insulation deterioration. The insulation particles are distributed and blown into the air you breathe every time the blower comes on.
 
We at Indoor Air Solutions recommend having your air ducts cleaned in early fall to help prevent being continuously exposed to these trapped allergens, and also reduce the cost of your winter utility bills. The buildup of debris inside your duct system reduces efficiency which makes the system work harder and costs go up. According to the American Council for an Energy-Efficient Economy (ACEEE), a system will not operate efficiently no matter how fine-tuned it is, if the ductwork is in poor condition. Proper cleaning and maintenance will keep your system running smoothly, cleanly and with less chance of breaking down.

  1. So I guess that cleaning ducts is really a necessity. It is pretty gross to think that unclean ducts can blow all sorts of garbage into our homes, I definitely don’t want that. If you recommend having the ducts cleaned every year, that’s what I should start doing.
