About Norcal Air Duct Cleaning

Family-Owned • Licensed & Insured • Serving the Bay Area Since 1980

A Bay Area Company Built on Trust, Quality, and Clean Air

For more than 42 years, Norcal Air Duct Cleaning has been dedicated to one mission: helping families and businesses across the Bay Area breathe cleaner, healthier air. What began as a small, family-owned operation has grown into a respected, multi-location service company trusted in San Jose, Brentwood, San Ramon, and surrounding communities — but our values have stayed exactly the same.

We are still family-owned.
We are still fully licensed and insured.
And we still believe in doing honest work, the right way, every time.

Our customers choose Norcal not just for what we do, but for how we do it, with professionalism, integrity, and care.

Over Four Decades of Experience - and a Long Record of Doing Things Right

In an industry where companies often appear and disappear overnight, Norcal’s 42+ years of continuous service stand out. Very few air duct cleaning companies in the Bay Area can match the depth of experience, consistency, and customer trust that Norcal has earned over four decades.

Our longevity is no accident. It comes from:

Providing reliable, high-quality service
Investing in advanced equipment and training
Treating customers with transparency and respect
Putting long-term relationships above short-term sales

The result? A business that’s grown steadily through referrals, repeat customers, and community trust.

Equipped for Real Results, Not “Blow and Go” Cleaning

Norcal uses industry-leading technology, including powerful negative-air systems, rotary brushes, and HEPA-filtered vacuums designed to remove dust, allergens, pet dander, mold spores, construction debris, and more — not just surface lint or loose particles.

This is a major differentiator in the Bay Area.
Many discount companies rush through jobs or outsource technicians.
Norcal does neither.

We follow a proven, multi-step cleaning process, built around safety, thoroughness, and long-term air quality improvement.

Local Knowledge That Makes a Real Difference

The Bay Area includes a wide range of microclimates, from the coastal humidity near San Francisco to the dry inland heat of Brentwood and the dense commercial corridors of San Jose. Each environment affects indoor air systems differently.

Norcal technicians understand these regional factors and adjust the cleaning approach accordingly. This local expertise is one reason homeowners, property managers, and commercial clients rely on us year after year.

Trusted in Ordinary Homes, and Extraordinary Places

Over the years, Norcal has been trusted to clean duct systems in settings ranging from everyday family homes to some of the Bay Area’s most unique and high-security environments.

Some of the stories that define our legacy include:

Cleaning the HVAC system aboard Steve Forbes’ private yacht in the 1980s
Completing work for secure government and military facilities, including Travis Air Force Base
Servicing critical infrastructure such as the Byron Water District, police departments, courthouses, post offices, and more
Helping homeowners recover long-lost items; toys, cash, and heirlooms, discovered deep inside ductwork

These moments highlight the trust placed in our team and the pride we take in treating every project, big or small, with the same professionalism and care.

Mission: Cleaner Air, Healthier Homes, Better Living

At Norcal, we believe air duct cleaning is ultimately about health, comfort, and peace of mind. Our mission is built around five core principles:

Clean Air That Improves Lives: Better sleep, fewer allergies, healthier breathing.
Unmatched Quality Through Technology: We use the best equipment because our customers deserve it.
