Why San Lorenzo Homeowners Choose Bellows Air Duct & Vent Co. of California
San Lorenzo homeowners tend to stay put. The ranch homes on streets like Hesperian Boulevard and Grant Avenue have been in the same families for decades, and the people who call us have usually already learned the hard way that a cheap coupon doesn’t mean a clean duct. We’ve built our reputation here on showing up when we say, charging what we quote, and leaving a camera record of every job.
Our technicians are background-checked, uniformed, and equipped with Rotobrush and Nikro systems. We answer calls with a live person 24 hours a day, no app required. The 90-Day Done Right Promise applies to every San Lorenzo job: if something isn’t right, we return at no charge with no paperwork to argue over. We’ve served the Broadmoor and Washington Manor neighborhoods regularly enough that our dispatchers know the typical duct layouts without looking at a map.
We don’t bait with a low price and change it at the door. The number you hear on the phone is the number on the invoice. That’s been our practice since 1984.
Air Duct Cleaning Services We Offer in San Lorenzo
Air Duct Cleaning in San Lorenzo
We clean the full supply and return duct network, from the main trunk lines to the branch runs serving each room. Our process includes a camera inspection before and after, so you see what was in there and what isn’t anymore. Learn more about our Air Duct Cleaning in San Lorenzo.
Dryer Vent Cleaning in San Lorenzo
Lint accumulation in dryer vents is a leading cause of house fires, and older San Lorenzo homes often have longer vent runs through unconditioned spaces where moisture from the marine layer compounds the problem. We clear the full vent path and verify airflow with a meter. Learn more about our Dryer Vent Cleaning in San Lorenzo.
HVAC Cleaning in San Lorenzo
The blower motor, evaporator coil, and plenum collect the same debris as your ducts, and cleaning them without cleaning the HVAC core leaves half the problem. We use professional-grade equipment to restore system airflow and reduce strain on aging compressors common in San Lorenzo’s original 1940s installations. Learn more about our HVAC Cleaning in San Lorenzo.
Duct Repair & Sealing in San Lorenzo
After seventy-plus years, San Lorenzo ductwork often needs more than cleaning. Cracked flex connections, corroded sheet metal seams, and collapsed runs in crawlspaces are routine findings here. We also offer our Duct Repair & Sealing in San Lorenzo to fix damaged sections and seal leaks with mastic and metal-backed tape, not duct tape.
Air Quality & Sanitizing in San Lorenzo
The marine layer humidity that seeps into San Lorenzo’s older ducts creates conditions for mold and mildew growth. Our Air Quality & Sanitizing in San Lorenzo treatment applies an EPA-registered product throughout the duct system, with particular attention to the damp crawlspace runs typical of Bohannon-era construction.
Neighborhoods We Serve in San Lorenzo
We work throughout ZIP 94580, with most calls coming from these areas:
- Broadmoor
- Washington Manor
- San Lorenzo Village (original Bohannon tracts)
- Hesperian Corridor
Typical response time is same-day or next-day for standard appointments, with emergency calls prioritized.
Why San Lorenzo’s Climate & Housing Affect Air Duct Cleaning
San Lorenzo sits on the East Bay flatlands directly adjacent to San Francisco Bay, and that geography shapes every duct system we open. The daily marine layer pushes higher ambient humidity than you’ll find twenty miles inland in Livermore or Pleasanton. That moisture finds its way into crawlspaces and attic runs through gaps in seventy-year-old ductwork, and once inside, it doesn’t dry out quickly. We regularly find mold and mildew growth in San Lorenzo ducts that owners didn’t suspect, particularly in the original flex connections routed beneath the slab-grade ranches on the north side of town.
The housing stock itself is the other half of the equation. Developer David D. Bohannon built San Lorenzo as one of the Bay Area’s first large-scale postwar planned communities between 1944 and the early 1950s. The single-story ranch and minimal-traditional homes went up fast and uniform, with duct systems that were adequate for the era but not built to last eight decades. We routinely encounter original galvanized sheet metal with corroded seams, early flex duct with cracked collars, and insulation wrap that has deteriorated to the point of falling off. The debris layer is usually substantial, and since these homes typically lack modern high-MERV filtration, regional wildfire smoke has added a visible dark ash strata over the ordinary household dust. San Lorenzo’s concentration of aged, poorly sealed residential ductwork is among the highest in the East Bay, and the cleaning requirements here are genuinely different from newer construction in neighboring cities.

FAQs About Air Duct Cleaning in San Lorenzo
Most standard single-system cleanings in San Lorenzo fall between $350 and $650, depending on home size, duct accessibility, and condition. Older Bohannon-era homes sometimes require additional time due to corroded access panels or collapsed flex runs. Call (855) 401-6006 for a free exact quote based on your specific home.
Every three to five years is standard, but San Lorenzo’s combination of aged ductwork, marine layer humidity, and wildfire smoke exposure means many homes here benefit from more frequent inspection. If you notice musty odors when the system runs, visible dust accumulation at vents, or increased allergy symptoms, it’s worth checking sooner. We include a camera inspection with every service so you can see whether cleaning is actually needed.
Yes, and we’re particularly careful with San Lorenzo’s vintage systems. The original galvanized metal and early flex ductwork require gentler agitation and lower-pressure vacuum settings than modern PVC or fiberglass systems. Our technicians adjust equipment accordingly and will flag any sections too deteriorated to clean safely, recommending repair or replacement instead.
Spot repairs and sealing are usually more economical than full replacement for isolated issues, which is what we most often find in San Lorenzo’s tract homes. However, if multiple runs are collapsed, corroded, or improperly routed through unconditioned space, replacement may be the better long-term value. We show you the camera footage and explain both options with upfront pricing before you decide. We also offer a free second opinion on any written estimate you’ve received elsewhere.
We answer calls live 24 hours a day and prioritize genuine emergencies, such as blocked ducts causing system shutdown or suspected mold contamination affecting respiratory health. Same-day service is often available for standard appointments as well. Call (855) 401-6006 and we’ll give you an honest timeframe.
