"Cleaning your ducts can be a big hassle, and one that can be easy to put off or even forget. For the most part, our air ducts are out of sight and out of mind. Unfortunately, leaving our air ducts unattended can have serious implications for the quality of the air in our home and the health of our families. Not only that, but keeping your ducts and vents clean can also save you money on your energy bills.
Unless you keep your windows and doors open 24/7, a large percentage of the air in your home has been circulated through your ventilation ducts. This is due, at least in part, to the growing popularity of energy efficient doors and windows and heavier home insulation which prevents any fresh air from entering the home. While the energy savings from these practices is good for both the environment and our wallets, it also means that we are exposed to a greater concentration of airborne dust, debris and organisms that may have built up in the duct work.
Ducts, being dark, moist, temperature controlled environments make for a perfect breeding ground for many types of mold, fungus and bacteria, many of which can harm humans. That means whenever your heating or air conditioning system fires up, along with that rush of comfortable air comes a blast of these organisms, as well as dust and debris which can adversely affect respiration. That is why it is so important to keep your ducts clean."
