Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterAir Duct Cleaning Company in San Lorenzo, CA
Air duct cleaning in San Lorenzo usually runs between $450 and $1,100 for a full system, depending on home size, crawl-space access, and how long the ductwork has gone without service. Most Bohannon-era homes here need roughly 4 to 7 hours. What makes San Lorenzo different from neighboring cities is the housing stock itself: 70-to-80-year-old tract homes with retrofitted duct systems wedged into damp, low-clearance crawl spaces under raised foundations. That geometry changes how we work, how we price, and what we find. Call (980) 447-2498 for a written quote before anything starts.
Why San Lorenzo Homes Are Different
San Lorenzo is the David D. Bohannon-built San Lorenzo Village, one of California’s first large post-WWII planned communities, developed from 1944 onward. The homes are overwhelmingly small ranch-style single-family houses on raised wood-frame foundations with crawl spaces rather than slabs. Central HVAC was retrofitted decades after construction, which means ductwork was squeezed into spaces never designed for it. In the original Village streets, we routinely find 1970s and 1980s flex duct that has partially collapsed or pulled apart at joints inside the crawl space. The cramped original geometry, decades of seismic micro-movement along the nearby Hayward Fault, and chronic dampness rotting the duct strapping all combine in ways you simply don’t see a few miles north in San Leandro’s later-built, better-ventilated housing.
San Lorenzo sits roughly 2 to 3 miles from the bay in the East Bay flatlands, and the persistent morning marine layer keeps crawl-space humidity elevated well into summer. That moisture infiltrates duct systems through poorly sealed connections, making mold and mildew inside ducts a recurring finding rather than an exception for technicians working these homes. When we open a return register in an original Village home, we expect damp air, corroded strapping, and insulation debris. It is the normal baseline here, not an outlier.
Our Main San Lorenzo Services
The two jobs San Lorenzo homeowners call about most are full air duct cleaning and dryer vent cleaning, with duct repair close behind once problems surface in the crawl space. Each service has its own dedicated San Lorenzo page with full pricing and local detail.
Air Duct Cleaning in San Lorenzo
Full-system air duct cleaning in San Lorenzo means negative-pressure extraction on every supply and return run, not just the registers you can see from the hallway. The real work happens in the crawl space, where retrofitted flex duct has spent decades pulling in ground moisture and shedding degraded insulation into the airstream. We seal off each branch, pull debris under vacuum, and leave you with before-and-after photos of your own ducts, not a generic stock image. Air Duct Cleaning in San Lorenzo covers pricing, what to expect on the day, and how to confirm the work was actually done.
Dryer Vent Cleaning in San Lorenzo
San Lorenzo dryers vent through exterior walls or up through the roof, and the long horizontal runs common in ranch-style homes collect lint faster than short vertical stacks in newer builds. A clogged dryer vent here is a fire hazard first and an efficiency problem second. We clean the full run from dryer to exterior cap, clear the lint trap bypass, and confirm proper airflow at the termination point. Dryer Vent Cleaning in San Lorenzo has the full breakdown of pricing and what a typical Village home needs.
Air Duct Repair in San Lorenzo
When flex duct separates inside a damp San Lorenzo crawl space, the fix is not always simple. The failed section needs removal, the connection point needs sealing, and the strapping that rotted away needs replacement before the new duct goes in. We also see crushed metal trunk lines where plumbing and electrical work was added long after the original build. Every repair gets a written guarantee, and if a covered repair fails, we return at no charge. Air Duct Repair in San Lorenzo explains what fails, what it costs, and how we stand behind the work.
