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.
Air Duct Cleaning Company in San Bruno, CA
Air duct cleaning in San Bruno typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What sets San Bruno apart is the coastal marine layer that keeps ductwork damp year-round, plus a housing stock split between aging post-war tract homes and newer rebuilds from the 2010 pipeline explosion era. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews work San Bruno from the Bay Area dispatch office. Call us at (361) 326-5060 for a written estimate before any work starts.
Why San Bruno Homes Are Different
San Bruno sits in a sweet spot on the Peninsula where the Pacific marine layer rolls in thick and lingers. That fog keeps temperatures mild, but it also means HVAC systems here run almost constantly and the air inside ducts never fully dries out. The result is a stubborn mix of mold spores, salt-laden moisture, and pollen that inland cities simply don’t see.
The housing tells two stories. West of El Camino Real, you’ll find dense blocks of post-WWII tract homes built from the 1940s through the 1960s with original galvanized steel or early flex ductwork now pushing 60 – 80 years. East toward the hills, the Crestmoor and Mills Estates neighborhoods were largely rebuilt after the 2010 gas pipeline explosion. Those homes are now 10 – 15 years old, and their builder-grade flex ducts are sagging at low points, collecting debris, and showing early microbial growth from the persistent damp.
We see the difference on every job. Older galvanized systems need careful rotary brush work to avoid dislodging rust scale into the living space. Newer flex systems require gentler handling to prevent tearing the plastic liner. One approach doesn’t fit both.
Our Main San Bruno Services
San Bruno homeowners call us for three core jobs. Each has its own page with full details on what we find locally and how we handle it.
Air Duct Cleaning in San Bruno
We clean the full supply and return network with Rotobrush rotary brush systems and Nikro negative-air machines, pulling debris out rather than pushing it deeper. In San Bruno, the coastal damp means we often find active mold colonies in trunk lines and sagging flex sections where condensation pools. We inspect with borescope cameras before and after so you see what came out. Air Duct Cleaning in San Bruno covers the full process, pricing, and what to expect.

Dryer Vent Cleaning in San Bruno
Lint buildup is a fire hazard, and San Bruno’s older homes often have long vent runs through walls or up to roof terminations that trap moisture along with lint. We clear the full run from dryer to termination, test airflow with an anemometer, and flag any sagging flex transitions that collect water. Dryer Vent Cleaning in San Bruno has the details.

Duct Sealing in San Bruno
Leaky ducts waste 20 – 30% of heated and cooled air, and San Bruno’s older galvanized systems are especially prone to seam separation and corrosion holes. We seal accessible ductwork with mastic and mechanical fasteners, then pressure-test to verify. Newer flex systems in rebuilt neighborhoods often have poorly sealed collar connections that we tighten and seal properly. Duct Sealing in San Bruno explains the full scope.
