According to NADCA, the average six-room home generates 40 pounds of dust per year. The EPA estimates Americans spend 90% of their time indoors. For O Fallon families, that means breathing recirculated air that passes through contaminated ducts thousands of times. In Missouri’s variable northeastern climate, moisture and temperature conditions accelerate contaminant buildup significantly compared to other regions.
Open one of your vent registers and look inside. That dark coating is years of accumulated dust, dead skin cells, pet dander, pollen, mold spores, and worse. Now multiply that by every linear foot of ductwork — typically 100-300 feet for an average O Fallon residence. Your HVAC pushes air through all of it every single day. In Missouri’s variable northeastern conditions where tornado alley debris and humidity is ongoing, this buildup is more aggressive than in milder climates.
Home improvement stores sell vent brushes and duct cleaning kits that reach a few inches past your vent cover. Your duct system extends 100+ feet. D&D Chimney Cleaning’s commercial equipment reaches every inch, removes contaminants household tools leave behind, and includes sanitization that prevents rapid recontamination. For O Fallon homeowners serious about their indoor environment, there’s no substitute for professional service.
