Air Duct Cleaning in San Bruno, CA
Whole-house air duct cleaning in San Bruno typically costs $380-$680 for a single-system home and is completed in one visit. We’re familiar with the contamination profile here: jet exhaust particulates from SFO flight corridors, marine aerosols driven through the San Bruno Gap, and original sheet-metal ductwork with seals that have dried over sixty-plus years. Call (855) 401-6006 for a free estimate with upfront pricing.
Why San Bruno Homes Are Different
San Bruno sits in the San Bruno Gap, the Coast Range break that funnels Pacific wind inland with a persistence unknown in neighboring Millbrae or South San Francisco. These sustained winds drive coastal particulates and marine aerosols through every gap in the building envelope, and the near-constant fog layer introduces humidity that settles into older duct systems with cracked mastic seals. Then there’s the airport. Homes under SFO’s active flight corridors accumulate a distinctive dark, carbonaceous film on supply-side duct interiors - jet exhaust byproducts and ultrafine aviation-related aerosols - a contamination profile measurably more concentrated here than anywhere else on the Peninsula without runway adjacency. The housing stock doesn’t help: compact ranch-style and bungalow homes built from the 1940s through 1960s for SFO workers and returning veterans, many still running original sheet-metal ductwork.
Air Duct Cleaning in San Bruno
Our Air Duct Cleaning crews work in San Bruno regularly, and we’ve developed specific protocols for the aviation-related soot and coastal humidity that define this market. Every job starts with camera inspection, finishes with camera verification, and carries our 90-Day Done Right Promise in writing.
Residential Duct Cleaning
San Bruno’s post-war housing stock - the ranches and bungalows from the 1940s through 1960s - mostly relies on original sheet-metal ductwork with aged mastic seals that have dried and cracked, pulling in unfiltered crawlspace and attic air. We seal accessible gaps, then extract accumulated debris with professional-grade Rotobrush equipment. A typical residential duct cleaning in San Bruno runs $380-$550 for a single-system home.
Supply Duct Cleaning
This is where San Bruno’s 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 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 runs $220-$340.
Why does my San Bruno home’s ductwork have a black, oily film on the vents near the ceiling?
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.
Dryer Vent Cleaning in San Bruno
Dryer vent cleaning in San Bruno typically runs $149-$189 for a standard single-family home, though homes near SFO corridors with heavy aviation particulate buildup run $189-$249. Most jobs are completed in under two hours. If your dryer is taking longer to dry clothes, or you notice a burning smell near the laundry area, you’re likely dealing with a vent blockage that needs immediate attention. Our Dryer Vent Cleaning service includes full camera inspection.
Vent Cleaning
Our vent cleaning process uses professional-grade Rotobrush and Nikro equipment to agitate and extract built-up lint, particulate, and microbial growth. In San Bruno’s older ranch homes, vents often run through unconditioned crawlspaces or exterior walls where the San Bruno Gap winds drive salt and moisture directly into the system. We clean the full run from dryer connection to exterior termination, not just the accessible sections. For homes with the sooty SFO-related film, we apply specialized pre-treatment before extraction.
Does living near SFO affect my dryer vent?
Yes - homes under active flight corridors accumulate ultrafine jet exhaust particulates that form a distinctive sooty, oily film inside vent interiors, trapping lint in dense, fire-prone layers not seen in inland jobs. This contamination requires specialized cleaning methods beyond standard lint removal. Our camera inspection identifies this profile so we can match our approach. Call (855) 401-6006 to schedule.
HVAC Cleaning in San Bruno
HVAC cleaning in San Bruno addresses the evaporator coils, blower assemblies, and air handlers that work harder than they should in this coastal environment. A typical evaporator coil cleaning runs $280-$420, blower cleaning ranges $240-$380, and full air handler service with cabinet resealing is $340-$520. Our HVAC Cleaning technicians inspect every return boot and trunk connection before starting.
Evaporator Coil Cleaning
The evaporator coil in your San Bruno home works harder than it should. Coastal humidity from the Gap condenses on fins already clogged with marine aerosols, and the near-constant fog layer promotes microbial growth that standard filter changes won’t touch. We pull the coil, clean it with foaming degreaser, and inspect the drain pan for standing water. In homes near SFO, we often find a thin oily film on the coil face that traces back to aviation particulates pulled through compromised return seals.
Is the fog in San Bruno a concern for my HVAC system?
The persistent marine fog through the San Bruno Gap introduces humidity that promotes microbial growth in duct insulation and on evaporator coils. Cleaning without antimicrobial treatment often fails within 60 days here. We include coil treatment and inspect drain pans specifically for this reason. Call (855) 401-6006 for an estimate.
Duct Repair & Sealing in San Bruno
Duct repair and sealing in San Bruno typically runs $180-$650 depending on whether we’re patching a single flex run or resealing an entire sheet-metal trunk system, and most jobs are completed in a single visit. The original mastic seals on San Bruno’s post-war ductwork have dried and cracked over sixty-plus years, pulling in unfiltered crawlspace air and the jet exhaust particulates that settle heavily in airport-corridor neighborhoods. Our Duct Repair & Sealing service uses Guardsman-grade sealants formulated for coastal exposure.
Duct Sealing
San Bruno’s post-WWII housing stock mostly relies on original sheet-metal ductwork with mastic seals that have dried and cracked. These gaps pull unfiltered crawlspace and attic air directly into your living space, along with the jet exhaust particulates that settle heavily in neighborhoods under SFO flight corridors. Our duct sealing service uses professional-grade mastic and mechanical fasteners to restore system integrity. We seal every joint, boot, and penetration point, then pressure-test to verify. Full system duct sealing in San Bruno runs $280-$480.
Can you repair metal ducts crushed by a falling oversized door?
Yes, we replace crushed metal sections with matching gauge galvanized steel, fabricate custom fittings where original components are no longer available, and seal all joints with mastic rated for San Bruno’s coastal humidity. We also assess whether surrounding supports need reinforcement to prevent repeat damage. A typical crushed-section repair runs $220-$400. Call (855) 401-6006 for an exact quote - estimates are free.
Air Quality & Sanitizing in San Bruno
Air quality and sanitizing service in San Bruno runs $280-$650 for most residential jobs. The distinctive smell in homes near SFO isn’t imagination - it’s ultrafine jet exhaust particulates, unburned hydrocarbons, and volatile organic compounds that settle in ductwork and recirculate every time the HVAC cycles. Our Air Quality & Sanitizing service treats the source, not the symptom.
Odor Removal
Standard cleaning won’t touch San Bruno’s aviation-related odors. We use professional-grade deodorizing compounds followed by HEPA filtration to extract the source material, not mask it. For a 1950s ranch on Crestmoor Drive, we treated exactly this problem: dried mastic on original sheet-metal ducts had cracked, letting unfiltered crawlspace air mix with jet-fuel residue from the SFO corridor. Odor removal in San Bruno typically runs $320-$480.
Why does my San Bruno home’s ductwork have a greasy black film even though I change my filters regularly?
The film is ultrafine jet exhaust particulate from aircraft operating at San Francisco International Airport, combined with unburned hydrocarbons that settle heavily in homes under the departure and approach corridors. Your filter catches what reaches it, but this material enters through gaps in aged duct seals and deposits on supply-side surfaces before ever reaching the return. We remove it with mechanical agitation and solvent pre-treatment, then seal the gaps so it stays out. Call (855) 401-6006.
