Your home's air ducts are its lungs, and maintaining their cleanliness is essential to a healthy interior atmosphere. But how often should homeowners schedule Air Duct Mold Cleaning to ensure optimal air quality and mold prevention?
Let’s dive into the factors that influence cleaning frequency and what experts recommend.
Why Timing Matters for Mold Cleaning
Mould can grow quickly in the presence of moisture—sometimes in as little as 24 to 48 hours. Waiting too long between cleanings increases the risk of mold buildup, especially in humid or damp climates. Inconsistent maintenance may lead to:
- Higher energy bills
- Airflow blockage
- Increased allergens and respiratory issues
Best Practice Table: Cleaning Frequency by Risk Level
| Risk Level | Suggested Cleaning Frequency |
|---|---|
| Low (dry climate, no pets) | Every 4–6 years |
| Moderate (some moisture) | Every 2–4 years |
| High (humid, pets, allergies) | Every 1–2 years |
| Visible Mold or Odors | Immediately |
