Air Duct Cleaning Services
Air Duct Cleaning Services in Marin, Sonoma & Napa County
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 the North Bay, including Marin, Sonoma, and Napa counties. Trusted since 1932, Ongaro & Sons delivers clean, healthy air backed by generations of HVAC experience.
All work is performed under active California contractors license #215233.

We use professional-grade, high-suction vacuum systems designed to remove dust, allergens, and buildup deep inside your air ducts without spreading debris throughout your home.

After cleaning, we offer expert insights on any issues affecting your HVAC system’s efficiency, such as poor duct design, leaks, or insulation problems, to help optimize your comfort and savings.
Why Air Duct Cleaning Matters

- You have pets that shed.
- You notice visible dust buildup or musty smells.
- You’ve moved into a new or previously owned home.

Why Ongaro & Sons for Air Duct Cleaning
We will tell you when cleaning is the answer and when it is not, which is the part most of this industry skips.
Schedule Service →An inspection before a quote
Duct cleaning is worth doing for real reasons: visible contamination, a rodent or water intrusion, dust after construction. It is not a routine annual service, and we will say so rather than sell it.
Sealing and cleaning are different problems
Cleaning removes what is in the duct. It does not fix a duct that is leaking. Confusing the two is why some homeowners pay for cleaning and see no change in comfort or dust.
The source gets identified
If dust returns quickly, something is feeding it: an unsealed return, a filter bypass, a crawlspace connection. Cleaning without finding that means cleaning again.
Filtration reviewed at the same visit
The right filter, correctly seated, does more for ongoing air quality than periodic cleaning. We check what is actually installed and whether the system can take a better one.
