Our Air Duct Cleaning Services in San Bruno
Residential Duct Cleaning
San Bruno’s housing stock is dominated by compact ranch-style and bungalow homes built from the 1940s through the 1960s to house SFO workers and returning veterans. Many still have original sheet-metal ductwork with aged mastic seals that have dried and cracked, pulling in unfiltered crawlspace and attic air. Our residential cleaning addresses this directly: we seal accessible gaps, then extract years of accumulated debris with professional-grade Rotobrush equipment. A typical residential duct cleaning in San Bruno runs $380-$550 for a single-system home.

Commercial Duct Cleaning
San Bruno’s commercial corridors along San Mateo Avenue and near the Tanforan shopping area include restaurants, medical offices, and retail spaces with higher occupancy and more demanding ventilation loads. We clean commercial systems to NFPA and NADCA standards, with scheduling that minimizes disruption to your business. Commercial duct cleaning in San Bruno typically starts at $680 and scales with system complexity.

Supply Duct Cleaning
This is where San Bruno’s unique geography shows up most clearly. Homes under the SFO departure corridor, particularly in Crestmoor and neighborhoods west of Highway 101, accumulate a sooty, oily film on supply-side duct interiors - jet exhaust byproducts and ultrafine aviation-related aerosols that settle heavily on diffuser boots and first-section trunk lines. This is not typical household dust. Our supply duct cleaning uses specialized agents to break down this carbonaceous residue, followed by full extraction. Supply duct cleaning as a standalone service in San Bruno runs $220-$340.

Return Duct Cleaning
Return ducts in San Bruno’s older homes often show the heaviest loading because they draw air through those cracked mastic seals, bypassing the filter entirely. We see return plenums packed with fiberglass insulation fragments, rodent debris from crawlspaces, and the same fine particulates that coat supply lines. Cleaning returns restores airflow balance and reduces the load on your HVAC blower. Return duct cleaning in San Bruno typically runs $180-$290.

Full System Cleaning
For homes with significant contamination on both supply and return sides, our full system cleaning covers every accessible trunk line, branch duct, boot, and plenum. In San Bruno, this is often the right choice for homes that haven’t been cleaned in 10+ years, or for properties showing the combined effects of aviation particulates, coastal humidity, and aged duct seals. Full system cleaning in San Bruno runs $480-$680 for most homes.

Video Inspection
Every job starts and ends with camera verification. For San Bruno’s older homes, video inspection often reveals cracked mastic seals, disconnected flex ducts, or corrosion in original sheet-metal systems that homeowners didn’t know existed. We document everything and show you the footage. Standalone video inspection runs $149-$199, and it’s included free with any cleaning service.

Common Air Duct Cleaning Problems We See in San Bruno Homes
- Cracked mastic seals on original sheet-metal ducts allow unfiltered crawlspace and attic air to bypass the filter entirely, recirculating ultrafine jet exhaust particles deep into living spaces. We see this in nearly every pre-1970 home we service in San Bruno.
- Persistent coastal fog and humidity in the San Bruno Gap promote mold growth inside aging duct systems, especially when supply-side boots trap moisture against the sooty film from aviation emissions. The combination creates a distinctive musty odor that standard filter changes won’t fix.
- Technicians overlook the distinctive oily film on diffuser boots near the airport, treating it as ordinary dust while missing the need for specialized cleaning agents to remove aviation-related aerosols. Without proper treatment, this film accelerates re-soiling and can damage painted surfaces.
- Disconnected or collapsed flex duct in crawlspaces is common in homes where original rigid duct was retrofitted with flexible material in the 1980s or 1990s. San Bruno’s strong Pacific winds and shifting soils stress these connections over time.

FAQs - Air Duct Cleaning in San Bruno
That film is ultrafine combustion particulate from jet exhaust, a contamination profile unique to San Bruno’s position under the SFO flight corridor. The sooty, oily residue settles on supply-side diffuser boots and first-section trunk lines, distinct from ordinary household dust, and it requires specialized cleaning agents to remove properly. Call (855) 401-6006 for a free inspection and exact quote.
Homes in Crestmoor and other neighborhoods under active flight paths should schedule duct cleaning every 2-3 years, more frequently than the standard 3-5 year recommendation for inland Peninsula cities. The accelerated accumulation of aviation-related particulates, combined with San Bruno’s coastal humidity, creates conditions that foul ductwork faster than in Millbrae or Burlingame. Call (855) 401-6006 to schedule.
Yes. Our camera systems clearly show gaps, cracks, and separation in original mastic seals on sheet-metal ductwork, which is common in San Bruno’s post-WWII housing stock. We document these findings and can recommend seal repair or duct sealing as part of your service. Video inspection is included free with any cleaning, or available standalone for $149-$199.
Our full system cleaning with specialized treatment removes aviation-related carbonaceous residue from duct interiors, boots, and trunk lines. We verify results with before-and-after camera inspection. The oily film requires specific cleaning chemistry that standard brush-and-vacuum methods won’t address. A typical full cleaning in San Bruno runs $480-$680. Call (855) 401-6006 for a free estimate.
Not necessarily. Cracked mastic seals can often be repaired or resealed without full duct replacement, which is typically far more expensive. Our video inspection shows the extent of the damage, and we’ll recommend repair when it’s viable and replacement only when the ductwork itself is corroded or improperly sized. We don’t sell duct replacement to solve a seal problem. Call (855) 401-6006 for an honest assessment.
