How Often Should Air Ducts Be Cleaned?

The general recommendation is to have your air ducts professionally cleaned every 3 to 5 years, according to the National Air Duct Cleaners Association (NADCA). However, the exact timing can vary depending on your home, location, and lifestyle.

You May Need More Frequent Cleaning If:

• 🐾 You have pets that shed hair and dander

• 🤧 Someone in the home has allergies or asthma

• 🏚️ You’ve done recent home renovations or construction

• 🐭 You’ve had rodent or insect infestations in the ductwork

• 🌬️ You live in a dusty or high-pollen area

• 🦠 There’s visible mold inside the ducts or vents

• 🏠 You just moved into a previously owned home

Signs It’s Time to Clean Your Ducts:

• Dust blowing from vents

• Unexplained musty or mildew odors

• Reduced airflow from vents

• Increase in allergy symptoms indoors

• Dark dust buildup around vent covers

Regular HVAC Maintenance Helps Too

Even between full cleanings, be sure to:

• Change your HVAC filters every 1–3 months

• Schedule annual HVAC system inspections

• Keep vents and returns clean and unobstructed
