When was the last time you had your air ducts professionally cleaned? If it’s been years—or if you’ve never done it—your home’s indoor air quality and HVAC system performance could be suffering.

Over time, air ducts collect dust, allergens, mold spores, pet dander, and other debris. These contaminants don’t just stay in your ducts—they recirculate throughout your home every time your HVAC system runs.

Ongaro & Sons provides expert air duct cleaning services that improve air quality, enhance HVAC efficiency, and help you breathe easier.

We proudly serve Northern California, including Marin, Sonoma, and Napa counties. With over 90 years of trusted service, Ongaro & Sons delivers clean, healthy air backed by generations of HVAC experience.

Why Air Duct Cleaning Matters

Regular air duct cleaning:

  • Improves indoor air quality
  • Reduces allergens and airborne irritants
  • Increases HVAC system efficiency
  • Helps extend the life of your HVAC equipment
  • Removes musty or stale odors from the air

Whether you’re dealing with seasonal allergies, uneven airflow, or high energy bills, a professional duct cleaning from Ongaro & Sons can make a noticeable difference.

How Often Should You Clean Your Air Ducts?

Most homes benefit from air duct cleaning every 3 years. However, you may need more frequent service if:

  • You’ve recently remodeled or renovated your home.
  • You suffer from allergies, asthma, or respiratory issues.
  • You have pets that shed.
  • You notice visible dust buildup or musty smells.
  • You’ve moved into a new or previously owned home.

If you’re unsure whether it’s time to clean your air ducts, contact us. We’ll assess your air ducts and provide honest, expert guidance. You can also follow our DIY guide on how to clean air ducts yourself—but our recommendation is to hire a professional, especially if you have never tried doing this before.
