Before we explain the pollutants it’s important to understand how your home breathes. They do breathe just like we breathe. Your heating and cooling system and the air ducts function much like your own heart and lungs.
When the heating or cooling system is turned on air is circulated through the home via the supply and return air ducts and other parts of your heating and cooling system. As the air circulates it picks up dust, dirt and dander and — if you have pets — pet hair. Other toxins are circulated, too. Household cleaners, paints and pesticides have been found in air ducts.
A Question or Two from Your Professional Air Duct Cleaner in Antioch
Your professional air duct cleaner in Antioch and the National Air Duct Cleaners Association (NADCA) have a question. How long has it been since you cleaned your air duct system and the parts of your heating and cooling system that process your home’s air? It has likely been rarely or — even more likely — never.
NADCA and your professional air duct cleaner in Antioch recommend cleaning your air ducts every three to five years and three years is preferable to five. Plus cleaning now, and at three years, has another benefit. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) says blowers and coils that are not clean will reduce the efficiency of your heating and cooling system by 40%.
A system running at 60% efficiency will cost you in higher heating and cooling bills.

Other components are from upholstery and are formaldehyde, dioxin, polychlorinated biphenyl (PCB) and polybrominated biphenyl.
A few studies have even found salmonella, Legionnaires Disease and strep in air ducts that have not been properly cleaned.
When its on, the heating and cooling system drops these toxins on furniture, walls, draperies, bedding, carpets and other household items as it circulates air. Much of it ends up back in the air duct system.
Those in the family or those visiting the home with allergies or breathing disorders are affected. The rest of us might notice occasional sore throats, red eyes or runny noses.
Not noticing because of no symptoms does not mean there is not a problem. Everyone is breathing those toxins.
