A Bay Area company that cleans the Bay Area.
Cal Duct Cleaning LLC was founded in Cupertino in 2015 on one principle: deliver the kind of home services we wished we could hire ourselves. A decade later, we've earned 1,000+ reviews and the trust of homeowners across Silicon Valley, the Peninsula, and the South Bay.
Why we started.
Cal Duct Cleaning started in 2015 after seeing a clear gap in the Bay Area market — too many operators quoting over the phone without seeing the job, showing up in unmarked vehicles with no documentation, and leaving homeowners with no proof of what was done.
We built Cal Duct Cleaning around the opposite approach: flat published prices, uniformed W-2 technicians, before-and-after photos on every job, and a written report you can actually keep. That standard hasn't changed.
By 2018 we had 500 reviews. By 2023 we covered the full Peninsula and South Bay. In 2026 we're past 1,000 reviews and still operating out of Cupertino.
Everything else — the portable HEPA equipment, the particle counting, the camera scopes, the photo reports — is in service of the same founding standard: be the home services company our neighbors are proud to refer.
Six things we'll never change.
W-2 technicians only
Never subcontractors. The person entering your home is on our payroll, background-checked, and accountable to us.
Flat, published pricing
What we quote is what you pay. No per-vent multipliers, no upsell commissions, no surprise line items at the end of the job.
Photo proof, every visit
Every service ends with a before-and-after photo report texted to your phone. If a repair is needed, you see exactly why.
HEPA-grade equipment
Medical-grade negative-pressure vacuums, rotary brush agitation, and EPA-registered sanitizers. The "air quality" companies' actual air quality matters.
Same-week availability
Our fleet is sized for Bay Area move-in surges. 90%+ of new bookings land within 7 days — every week of the year.
No scare tactics
If you don't need a service, we tell you. Our techs aren't paid on commission to find phantom repairs. We'd rather earn the next twenty years of your business.
