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 Bruno, CA
Air duct cleaning in San Bruno runs between $349 and $589 for most single-family homes, with the final figure set in writing before any work begins. What makes San Bruno jobs different from neighboring Peninsula cities is the San Bruno Gap, a low break in the Coast Range that pushes cold, damp marine air through the city year-round. That persistent humidity, combined with postwar homes built between 1945 and 1965, means older duct systems here carry moisture problems that drier Bay Area markets rarely see. Call (469) 972-3151 and you’ll reach a live person who can talk through your home’s specific setup.
Why San Bruno Homes Are Different
San Bruno sits directly in the path of the San Bruno Gap, the geographic opening that funnels Pacific fog and wind through the city more intensely than nearly any neighboring Peninsula community. The result is indoor humidity that stays elevated for months at a time, which accelerates condensation inside crawl-space ductwork and raises the baseline risk of mold colonization inside HVAC systems. Technicians who work mostly in drier inland markets often treat this as an unusual finding. For San Bruno homes, it’s a routine condition.
The housing stock compounds the issue. San Bruno’s residential core is overwhelmingly postwar tract housing built between roughly 1945 and 1965, and a large share of those homes still run original or first-generation sheet-metal ducts with poorly sealed joints and undersized returns. These systems are now 60 to 75 years old, carrying decades of accumulated debris, and their loose seams make them especially vulnerable to the moisture that the local marine microclimate delivers. In the hillside neighborhoods west of El Camino Real, where fog sits heaviest and longest, crawl-space flex duct connections on older slab-and-raised-foundation hybrids routinely show condensation staining and early mold at every collar joint. We flag that as a near-certain finding on any pre-1970 home in that corridor before we even open the first access panel.
There’s also the airport factor. San Bruno lies immediately under SFO’s active flight corridors, and fine particulate matter from jet exhaust is a measurable, ongoing contributor to duct contamination here. That’s a different dust profile than what you’d find in San Mateo or Burlingame, and it means San Bruno ducts accumulate a finer, stickier residue that clings to duct walls and recirculates through living spaces.

San Bruno homeowners call us most about two jobs, and each has its own detailed page with pricing, what to expect, and the conditions that affect the work here.
Air Duct Cleaning in San Bruno
Air duct cleaning removes the accumulated dust, pet dander, and particulate buildup from your supply and return ductwork, registers, and the main trunk lines. In San Bruno, we also address the moisture-driven contamination that the Gap climate produces, including mold growth at duct joints and condensation staining inside crawl-space runs. Our technicians use Rotobrush rotary brush agitation to dislodge debris at the duct wall, paired with negative-air extraction that pulls loosened material out of the home rather than blowing it through the living space.

Dryer Vent Cleaning in San Bruno
Dryer vent cleaning clears the lint that builds up behind your dryer and along the entire vent run to the exterior termination point. San Bruno’s older homes often have long, uninsulated vent runs through cool crawl spaces, where moist exhaust air condenses and turns lint into a damp, compacted plug. That’s not just a drying-efficiency problem; it’s a fire hazard. We clean the full run, including the lint trap bypass, and check the exterior cap for proper airflow. Dryer Vent Cleaning in San Bruno

For most single-family homes, no. Duct and dryer vent cleaning is interior maintenance that doesn’t require HOA sign-off. If you’re in a townhome or condo community with shared duct runs, check your CC&Rs before scheduling, and we’ll work with whatever access your HOA requires.
Yes. The Gap climate keeps crawl spaces damp through much of the year, and that moisture condenses inside uninsulated or poorly sealed ductwork. Over time, that leads to mold growth at joints and collar connections, especially in homes built before 1970.

What San Bruno Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
