Maintaining clean air ducts is essential for better indoor air quality, improved HVAC efficiency, and overall home health. However, according to the Canada Mortgage and Housing Corporation (CMHC) and other industry experts, air duct cleaning is not required regularly for most homes. Instead, it should be done only when necessary to ensure a clean and efficient HVAC system.

So, how often should you clean your air ducts? Let’s break it down.

Recommended Frequency for Air Duct Cleaning

✅ Every 3-5 years (if needed): This is a general guideline for homes that do not have specific air quality concerns.

✅ Every 2-3 years: If you have pets, allergies, or respiratory issues, frequent duct cleaning may help reduce allergens like pet dander, dust, and pollen.

✅ As needed: If you notice visible dust buildup, debris, or airflow blockages, it’s time for a professional inspection.

When Should You Schedule an Air Duct Cleaning?

While regular cleaning isn’t always necessary, here are situations where professional duct cleaning is highly recommended:

🔹 After major home renovations – Construction debris, drywall dust, and sawdust can accumulate in your air ducts. Professional air duct cleaning will remove these particles, improving air quality.

🔹 If mold is present – Mold in your air ducts can trigger allergies and respiratory problems. If you notice a musty smell or visible mold, it’s essential to remove mold from air ducts and fix the source of moisture.

🔹 After a pest infestation – Rodents and insects can nest inside ductwork, leaving behind droppings and debris. Pest control should be followed by thorough duct cleaning.

🔹 If there are noticeable airflow blockages – Dust, pet hair, and other debris can reduce your HVAC system’s efficiency. A professional duct cleaning service can restore airflow and lower energy costs.

🔹 If there is excessive dust buildup near vents – If your home gets dusty quickly, even after cleaning, your air ducts may be the source.

Preventive Maintenance Tips for Cleaner Air Ducts

To minimize dust accumulation and improve indoor air quality, follow these preventive maintenance steps:

✔ Change furnace filters regularly – Replace air filters every 1-3 months to trap dust, pollen, and other airborne pollutants. Shop high-efficiency air filters.

✔ Vacuum and clean air vents – Dust and dirt can accumulate in your registers and vents. Clean them every few weeks to prevent buildup.

✔ Maintain proper humidity levels – High humidity can lead to mold growth inside ducts. Use a dehumidifier or air conditioner to keep humidity levels between 30-50%.

✔ Ensure ductwork is properly sealed – Leaky air ducts allow dust, pests, and pollutants to enter your HVAC system. Schedule an air duct inspection to check for leaks.
