When it comes to the air we breathe at home, there’s a lot of misinformation out there. Many homeowners assume their indoor air is cleaner than it really is—or that air duct cleaning is only necessary under certain circumstances. At Advanced Air Duct Cleaning, we’ve seen firsthand how these myths can keep families from addressing real issues affecting their comfort, health, and HVAC efficiency. Let’s set the record straight.

Myth #1: “Duct cleaning is only for older homes.”

Fact: Dust, debris, and allergens build up in every home—new or old. Construction debris like drywall dust, sawdust, and insulation often end up in brand-new ductwork before you even move in. Pet hair, dander, and everyday household dust then accumulate year after year. Whether your home is 2 years old or 20 years old, duct cleaning makes a measurable difference.

Myth #2: “My HVAC filter is enough to keep the air clean.”

Fact: Standard filters mainly protect your equipment, not your health. Most only capture larger particles, letting smaller allergens and contaminants flow right through. Even with high-efficiency filters, dust and pollutants still settle inside the ductwork. Without cleaning, these particles get recirculated every time your system runs.

Myth #3: “If I can’t see dust, my air must be clean.”

Fact: Indoor air pollution is often invisible. Pollen, mold spores, pet dander, and volatile organic compounds (VOCs) can all circulate through your system undetected. The EPA has found that indoor air is often 2–5 times more polluted than outdoor air. A clean duct system helps minimize these hidden threats.

Myth #4: “Duct cleaning is only about air quality, not energy savings.”

Fact: Clean ducts don’t just mean healthier air—they mean a healthier HVAC system. Dust buildup restricts airflow, forcing your system to work harder. Regular cleaning improves efficiency, reduces wear and tear, and can even extend the life of your equipment.

Myth #5: “Duct cleaning is a one-time job.”

Fact: Just like changing filters or servicing your furnace, duct cleaning is part of routine maintenance. Most homes benefit from a professional cleaning every 3–5 years, and more often if you have pets, allergies, or recent renovations.
