What Builds Up Inside Your Ducts
Dust, skin cells, pet hair, pollen, drywall dust from renovations and sometimes insect or rodent debris. Filters catch some of it, but over the years a layer forms inside supply and return ducts that the blower keeps stirring up.
Roswell's Climate Makes It Worse
Metro Atlanta routinely ranks among the worst U.S. cities for spring pollen, and Roswell's heavy tree cover sits right in the middle of it. Every March and April, a yellow film covers cars, decks — and the inside of your return ducts.
Then come long, humid summers along the Chattahoochee River. Air conditioners run for months, and moisture combined with dust can lead to musty smells and mildew growth inside the system.
Health And Comfort Benefits
Clean ducts mean less recirculated dust and allergens, fresher-smelling air, better airflow to upstairs rooms, and less strain on your HVAC equipment. For households with children, seniors, pets, asthma or allergies, the difference is often noticeable.
How Often Should You Clean?
A common recommendation is every 3–5 years. For Roswell homes with pets, allergies, recent remodeling, or systems older than 15 years, every 2–3 years is a smart schedule. Dryer vents should be cleaned every year.
