Fast, Reliable Air Duct Cleaning Across San Francisco
Air duct cleaning in San Francisco typically runs $380-$780 for a full residential system, with most jobs completed in a single visit by our background-checked crew. We answer calls live, 24 hours a day, and we carry the specialized equipment needed for San Francisco’s tight Victorian floor chases and retrofitted ductwork.
We’ve been serving San Francisco homeowners since 1984, and we know the difference between a standard suburban duct run and the cramped, non-standard chases hidden beneath the floorboards of a Mission District Edwardian flat. Our technicians arrive with Rotobrush flexible-shaft systems, Nikro HEPA vacuums, and the patience to navigate access points that were never designed for modern HVAC. Parking’s tight, alleys are narrow, and building access often requires coordination with multiple tenants. We plan for all of it before we arrive.

Why Bellows Air Duct & Vent Co. of California Is San Francisco’s Preferred Air Duct Cleaning Company
San Francisco homeowners don’t call us because we’re the cheapest. They call us because they’ve already been burned by a low-bid operator who showed up with a shop vac and a coupon, then tried to upsell them in the hallway. We’re the square-deal alternative. Our Air Duct Cleaning team has built a 42-year reputation on one honest price shown before work starts, camera-verified results every time, and a 90-Day Done Right Promise stamped on every job.
Our reviews from San Francisco customers consistently mention the same things: we show up when we say we will, we explain what we found on camera before we start, and we don’t change the price at the door. Response time to San Francisco is typically same-day or next-day for standard appointments, and we maintain emergency availability for situations like post-wildfire ash contamination or active mold concerns.
We understand San Francisco’s housing stock in a way that out-of-town franchises don’t. We know that a pre-1980 building in Visitacion Valley might have asbestos-wrapped duct insulation that needs identification before any cleaning proceeds. We know that the marine layer pushing through the Richmond District keeps indoor humidity elevated even in July, creating mold conditions that Central Valley techs have never encountered. And we know that coordinating access in a Chinatown multi-unit Victorian requires patience and clear communication with multiple tenants, not just a knock on one door.
Our Air Duct Cleaning Services in San Francisco
Residential Duct Cleaning
San Francisco’s dominant housing type, the late-19th and early-20th century Victorian or Edwardian flat, presents residential duct cleaning challenges found almost nowhere else in California. Most of these buildings were rebuilt after the 1906 earthquake with construction methods that predated forced-air systems entirely. Any ductwork present was added decades later as an afterthought, often routed through undersized floor voids and interior partition cavities with no clean-out access between levels. Our Residential Duct Cleaning service is built around this reality. We use flexible-shaft brush systems that can navigate 4-inch floor chases, and we camera-inspect every run before and after to verify debris removal without damaging old duct walls. A typical San Francisco residential cleaning runs $380-$620 for a single-unit system, with multi-unit buildings quoted after access assessment.
Commercial Duct Cleaning
Commercial properties in San Francisco’s dense urban core face their own constraints: limited parking for our service vehicles, alley-load delivery requirements, and the need to work around business hours in retail corridors like the Mission District or Chinatown. We schedule early-morning or after-hours appointments to minimize disruption, and our crew arrives with portable equipment that doesn’t require a loading dock. Commercial duct cleaning in San Francisco typically ranges from $680-$1,400 depending on system size and access complexity. We provide upfront pricing before any work begins, consistent with our founding promise of no scare tactics and no bait coupons.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your living spaces, and in San Francisco’s retrofitted systems they often terminate in floor registers that double as the only access points. This means our technicians must work backwards from each register, using camera-guided flexible shafts to reach debris accumulated in the supply trunk. The marine layer’s persistent humidity means these supply lines are particularly prone to mold colonization, especially in south-facing units where solar gain creates temperature differentials that draw moist air inward. Supply duct cleaning as a standalone service in San Francisco runs $220-$380.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in San Francisco’s Victorian flats they often serve as the building’s primary air pathway, collecting decades of dust, pet dander, and cooking particulate from multiple households. Return duct cleaning requires particular care in these buildings because the return plenum may be shared across tenant units with no physical separation. We identify these configurations during our initial video inspection and coordinate with all affected tenants before proceeding. Standalone return duct cleaning in San Francisco is typically $180-$320.
Video Inspection
Every job we perform includes camera inspection of ductwork before and after cleaning, but we also offer Video Inspection as a standalone diagnostic service for San Francisco homeowners who want to understand their system before committing to full cleaning. This is especially valuable in pre-1980 buildings where asbestos-wrapped insulation or original asbestos-backed duct tape may be present. Our cameras transmit real-time footage from inside the duct run, allowing us to identify access limitations, debris load, moisture damage, and potential asbestos-containing materials without invasive exploration. Standalone video inspection in San Francisco is $149-$220, credited toward any subsequent cleaning.
Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, trunk lines, registers, grilles, and the HVAC unit itself. In San Francisco’s challenging housing stock, this is often the only approach that fully addresses cross-contamination between units and the deep debris accumulation in retrofitted chases. We use Abatement Technologies portable HEPA filtration to protect indoor air quality during the cleaning process, and we complete most full system jobs in a single visit. Pricing for Full System Cleaning in San Francisco ranges from $580-$780 for typical single-family and single-unit applications, with multi-unit buildings assessed individually.

Trusted Brands We Service in San Francisco
We maintain equipment from Rotobrush, Abatement Technologies, and Aprilaire, the same brands serious HVAC contractors specify when they’re working in demanding environments. For San Francisco customers, this means we don’t need to special-order parts or rent equipment for your job. Our Rotobrush flexible-shaft systems handle the tight chases of Nob Hill Victorians. Our Abatement Technologies HEPA vacuums contain fine particulate during post-wildfire cleanings. And our Aprilaire air quality monitors help track humidity levels after marine-layer mold remediation. We stock local parts for fast turnaround, and our technicians train on each platform annually.
Common Air Duct Cleaning Problems We See in San Francisco Homes
- Marine-layer mold in ducts without any visible leak. San Francisco’s persistent coastal humidity pushes moisture-laden air through building envelopes year-round, raising indoor relative humidity even on sunny days. Ducts that sit idle in this environment develop mold colonization that dry-summer inland cities never see.
- Asbestos-wrapped duct insulation in pre-1980 buildings. A large majority of San Francisco’s housing stock predates 1980, and many of these buildings retain original asbestos-backed duct tape or wrapped insulation. Cleaning without proper identification risks hazardous fiber release and illegal removal.
- Brush systems too large for retrofitted chases. Standard rotary brush heads designed for modern 6-inch ductwork won’t fit through San Francisco’s 4-inch floor voids and partition cavities. Using them damages old duct walls or dislodges debris into neighboring tenant units.
- Failed tenant coordination in multi-unit buildings. In dense Victorian flats, a single duct system often crosses between two or three separately-tenanted floor units with no clean-out access between levels. Cleaning one unit without coordinating access to all connected units leaves debris in place and creates tenant complaints.

FAQs - Air Duct Cleaning in San Francisco
The marine layer pushes cool, moisture-laden air through San Francisco building envelopes for much of the year, raising indoor relative humidity even when it’s sunny outside. Ducts that sit idle in this environment, especially in south-facing units with temperature differentials, develop mold colonization without any plumbing leak or roof failure. During our video inspection, we identify moisture-damaged sections and recommend targeted sanitizing after cleaning. Call (855) 401-6006 for an assessment.
We don’t start until we’ve secured access to all connected units. In a Nob Hill Victorian flat, we once cleaned a duct system that crossed three tenant units with no intermediate clean-out access; we used a Rotobrush with a flexible shaft to navigate undersized floor chases, extracting decades of co-mingled debris and resolving a persistent mold issue from the coastal marine layer. We work with property managers and individual tenants to schedule coordinated access, and we document which sections were cleaned from which access points. Call (855) 401-6006 to discuss your building’s layout.
We do not clean ducts with intact asbestos insulation, and we identify it during our pre-cleaning video inspection. Disturbing asbestos-containing materials without proper abatement procedures is hazardous and illegal. If we find asbestos-wrapped ducts or original asbestos-backed tape, we refer you to a licensed asbestos abatement contractor for safe removal, then return to clean the system afterward. This identification service is included in our standard video inspection. Call (855) 401-6006 to schedule.
Replace your HVAC filter immediately after smoke clears, then schedule a full system cleaning with HEPA-contained debris removal within 30 days. During events like the 2018 Camp Fire, San Francisco residents sealed windows and recycled air through duct systems, depositing fine particulate ash throughout the ductwork; this ash retains moisture from the marine layer, accelerating mold growth. Our post-wildfire cleaning protocol includes Abatement Technologies HEPA filtration and camera verification of ash removal. Call (855) 401-6006 to book.
Yes. Our camera systems use flexible fiber-optic shafts as narrow as 5.5 millimeters, designed specifically for the restricted access points of retrofitted San Francisco ductwork. We’ve navigated floor chases in 94122, ceiling hatches in 94123, and sub-floor cavities in 94124 that would stop standard inspection equipment. The camera transmits real-time footage to a handheld monitor, so you see what we see as we work. Call (855) 401-6006 to schedule a video inspection.
We’re here when you need us. Calls are answered by a live person, 24 hours a day, not a voicemail system or an app. Our background-checked, uniformed technicians serve San Francisco with the same standards we’ve upheld since 1984: one honest price shown before we start, camera-verified results, and a 90-Day Done Right Promise backed in writing. If the work isn’t right, we make it right. No paperwork, no arguing. That’s how we’ve operated for over four decades, and that’s how we’ll handle your job.
