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.

We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve San Bruno from our Bay Area dispatch office.

Why Hollis Air Duct Cleaning Is San Bruno’s Preferred Dryer Vent Cleaning Company
We’ve been in business since 2004, and our Dryer Vent Cleaning team has worked enough San Bruno homes to know the difference between a 1950s tract house on Crystal Springs Road and a post-2010 rebuild on the 600 block of Crestmoor Drive. The vent systems aren’t the same, and neither is the lint we pull out of them.
Our technicians are background-checked and uniformed. The price is written down before any work starts, and it doesn’t move at the door. Every job carries our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit.
Phones are answered by a live person, not a voicemail loop. That’s not a marketing claim; it’s how we operate, including when San Bruno’s fog rolls in and appointment windows matter more than ever.
Dryer Vent Cleaning Company in San Bruno
Dryer Vent Cleaning Company service in San Bruno means more than brushing out the lint trap and calling it done. In this city, with its persistent marine layer and post-rebuild housing stock, the job requires understanding how damp coastal air turns lint into a matted, felt-like blockage that standard equipment won’t touch. We use Rotobrush rotary whip systems under negative air pressure from Nikro machines, with HEPA filtration, to remove lint that has bonded to flex duct walls rather than simply sitting loose.
A typical Dryer Vent Cleaning in San Bruno runs $180 – $280 for a straight run under 15 feet, and $240 – $340 for longer runs, multiple elbows, or rooftop terminations common in Mills Estates and Crestmoor rebuilds. Bird guard installation, if needed, is $85 – $140 additional.
What We Remove From San Bruno Vents
Surface lint at the trap is dry and crumbly. Deeper in the run, San Bruno’s fog keeps it damp. We extract both, plus any construction debris left from original build-out in post-2010 homes. The Rotobrush whip scrubs the duct wall while negative pressure pulls dislodged material into a sealed container, not your laundry room.
When San Bruno Homeowners Should Schedule
Annual cleaning is the baseline for most homes. In San Bruno, we recommend every 10 – 12 months if your dryer vent terminates through the roof or has multiple elbows, because the marine layer extends drying time and increases lint accumulation. If your dryer needs two cycles, that’s not normal wear. That’s a blocked vent.
Dryer Vent Inspection in San Bruno
Dryer Vent Inspection in San Bruno starts with a camera run through the full vent pathway, from the dryer’s transition duct to the exterior cap. We document what we find, show you the footage, and explain whether cleaning, repair, or rerouting is needed. A standalone inspection runs $120 – $180; if you proceed with cleaning, we credit the inspection fee toward the full service.
Inspections are particularly valuable for homes rebuilt after the 2010 pipeline explosion. Those builder-grade flex ducts are now 10 – 15 years old. They’ve been sagging at unsupported elbows since installation, collecting lint in low points where San Bruno’s fog keeps it permanently damp.
Camera Documentation and Airflow Testing
Our techs use borescope cameras to record the interior condition, then measure airflow velocity at the exterior cap with a calibrated anemometer. A properly venting dryer should move 1,500+ feet per minute at the termination. We show you the number before and after any work.
Code and Safety Check
We verify that your vent run meets California building code for material type, maximum length, and termination clearance. Many post-2010 San Bruno rebuilds used flexible transition duct behind the dryer where rigid metal is now required. We flag it and quote replacement if needed.
Trusted Brands We Service in San Bruno
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Guardsman. For San Bruno homeowners, this means we stock parts and accessories locally rather than ordering from a warehouse two states away. If your vent cap is damaged by coastal corrosion or you need a Guardsman bird guard installed to keep Pacifica crows from nesting in your termination, we typically have the hardware on the truck. The same tools serve commercial crews; we bring them to your home in San Bruno and explain what each piece does before we start.
Common Dryer Vent Cleaning Problems We See in San Bruno Homes
- Builder-grade flex duct sagging at elbows. Post-2010 rebuilds in Crestmoor and Mills Estates used unsupported flex duct at the first elbow. The low point collects lint, and San Bruno’s marine layer keeps it wet enough to mat into a solid block. A surface cleaning misses it entirely.
- Rooftop terminations clogged by fog-moistened lint. Many San Bruno homes vent through the roof. The combination of lint and persistent damp air creates a paste-like buildup at the cap that standard blowers won’t clear. We remove the cap, clean the throat, and verify backdraft damper operation.
- Thermal cutoff trips before the homeowner notices slow drying. Because San Bruno rarely gets hot enough to make a poorly venting dryer obvious, the first symptom is often the safety switch shutting the dryer down mid-cycle. By then, the vent is significantly obstructed and at elevated fire risk.
- Construction debris in newer duct systems. Homes rebuilt after 2010 are hitting their first major cleaning cycle. We’ve found drywall dust, wood chips, and even dropped fasteners in vent runs that were never cleaned after original construction.

FAQs About Dryer Vent Cleaning in San Bruno
Yes, and often more urgently than an older home. Builder-grade flex duct installed during reconstruction has likely been sagging at unsupported elbows since day one, creating low points where lint accumulates. San Bruno’s marine layer keeps that lint damp, so it mats rather than staying loose and passable. We recommend a first full inspection at 8 – 12 years for post-rebuild homes. Call (361) 326-5060 to schedule.
Yes. Concord’s hotter, drier summers allow lint to dry and partially clear with normal airflow. San Bruno’s persistent fog means lint deeper in the run stays damp year-round, bonding to flex duct walls and forming dense mats that require mechanical agitation to remove. The lint you see in your trap is dry and crumbly; the lint 10 feet down the run is not. That’s why we use Rotobrush whips rather than just air blowing.
Watch for clothes that need two cycles, a dryer that’s hot to the touch on the outside, or a musty smell in the laundry room. In San Bruno, the marine layer masks some symptoms because the ambient air is cool, so the dryer’s external heat is less noticeable. A camera inspection confirms what you can’t see. We offer free estimates, and a standalone inspection is $120 – $180.
No. Source removal with a rotary brush system under negative pressure is the standard we follow. The brush dislodges bonded lint; the vacuum captures it before it enters your home. We then verify airflow at the exterior cap and inspect the termination for damage or improper clearance. “Blowing air through” can compact a blockage further or force lint into the dryer cabinet. We don’t do it.
NADCA’s source removal protocol applies to any HVAC pathway, including dryer vents. It requires mechanical agitation, containment, and post-cleaning verification. For San Bruno homes with fog-moistened lint mats, this matters: without agitation, the blockage stays. Without containment, debris enters your living space. Without verification, you’re trusting that it worked. We document airflow before and after, in writing, on every job.
