Why San Francisco Homeowners Choose Bellows Air Duct & Vent Co.
We’ve been driving our vans across the Bay Bridge and up the 101 to San Francisco homes for over thirteen years now. In that time, we’ve cleaned ducts in the narrow crawl spaces of Russian Hill Edwardians, the converted lofts of SoMa, and the multi-unit flats packed along the Mission’s Valencia corridor. San Francisco customers don’t call us for flash. They call because they want the job finished right the first time, with a price that doesn’t budge once we’re in the door.
Our technicians are background-checked and uniformed, and every job starts and ends with a camera inspection you can see for yourself. The 90-Day Done Right Promise applies to every San Francisco home we enter: if something’s not right, we come back and fix it. No forms to fill out, no runaround. We also keep a live person on the phone 24 hours a day, because we know HVAC problems don’t wait for business hours.
We’re licensed and insured, and we carry professional-grade equipment from Rotobrush and Nikro, the same brands serious HVAC contractors specify for commercial work. Whether you’re in a 1906-rebuilt flat in the Tenderloin or a mid-century building near Daly City, we know how to access ductwork that was never designed to be cleaned.
Air Duct Cleaning Services We Offer in San Francisco
Air Duct Cleaning
We remove built-up dust, debris, and microbial growth from supply and return ductwork using Rotobrush agitation and HEPA-filtered vacuum collection. Every San Francisco job includes before-and-after camera documentation so you see what came out of your system. Learn more about our Air Duct Cleaning in San Francisco.
Dryer Vent Cleaning
Lint accumulation in dryer vents is a leading cause of residential fires, and San Francisco’s older multi-unit buildings often have vent runs that span multiple floors with inadequate access for cleaning. We clear the full length of the vent path and verify airflow restoration with digital measurement. Learn more about our Dryer Vent Cleaning in San Francisco.
HVAC Cleaning
Our HVAC cleaning service covers evaporator coils, blower assemblies, and cabinet interiors where moisture from Karl the Fog’s daily cycle breeds mold in San Francisco’s chronically damp climate. We use Nikro equipment and antimicrobial treatments where appropriate, always with your approval and upfront pricing. Learn more about our HVAC Cleaning in San Francisco.
Duct Repair & Sealing
Retrofitted ductwork in San Francisco’s pre-1915 housing stock suffers from separated seams, corroded sheet metal, and failed tape at joints that were never meant to flex. We repair accessible damage and seal leaks with mastic and mechanical fasteners, not duct tape that will fail again in six months. For more extensive issues, see our San Francisco Duct Repair & Sealing service.
Air Quality & Sanitizing
For homes with persistent musty odors or visible mold in camera inspections, we apply EPA-registered sanitizing agents from Abatement Technologies and Honeywell distribution partners as part of our Air Quality & Sanitizing in San Francisco service. This is not a substitute for remediation of active water intrusion, but it addresses biological growth within the duct system itself when moisture has been controlled.
Neighborhoods We Serve in San Francisco
We work across the city, with same-day and next-day availability throughout our coverage area. Most San Francisco appointments are scheduled within 24 to 48 hours of your call.

- SoMa - Converted warehouse lofts with industrial rooftop units and long-neglected duct spans
Why San Francisco’s Climate & Housing Affect Air Duct Cleaning
San Francisco’s dominant housing stock, Victorian and Edwardian flats built before forced-air HVAC existed, means that any ductwork is a retrofit, crammed into wall cavities, floor chases, and crawl spaces never engineered for it. These systems have sharp bends that trap debris and access points that require specialized equipment and patience to navigate properly. Layered on top of this, the city’s persistent marine fog layer drives chronic moisture into poorly-sealed, retrofitted ducts, so mold and mildew remediation is the primary concern for SF duct cleaning jobs, not the simple dust accumulation that defines the work in drier inland California cities like Fresno or Sacramento.
The cool marine climate means most residential units run heating only lightly and almost never run air conditioning. Ducts sit largely stagnant for months, allowing moisture drawn in by the daily fog cycle to condense inside poorly-insulated runs and foster mold growth without the regular airflow that would otherwise dry things out. Even summer brings heavy morning fog and 55 to 60 degree temperatures that keep interior surfaces cool enough for condensation to recur season after season.
In the dense restaurant corridors of Chinatown and the Mission, residential ductwork in upper-floor flats often draws makeup air through shared shafts adjacent to commercial kitchen exhaust. Our technicians frequently find grease film and cooking particulate coating supply ducts in apartments where the residents have never cooked a meal. This contamination pattern is essentially unique to San Francisco’s hyper-dense mixed-use building stock, and it requires cleaning protocols different from standard residential dust removal.

FAQs About Air Duct Cleaning in San Francisco
Most San Francisco homes fall between $350 and $650 for a complete air duct cleaning, depending on system size and accessibility. Victorians with retrofit ductwork in wall cavities take longer to access than homes with standard basement or attic runs, which affects the final price. Call (844) 685-6342 for a free estimate based on your specific layout - we’ll ask about your building age and vent count so there are no surprises.
Every three to five years is standard, but San Francisco’s fog-driven moisture means many homeowners need attention sooner for mold and mildew concerns rather than dust buildup. If you smell mustiness when the heat first kicks on, or if you’ve never had ducts cleaned since moving into a pre-1950 flat, schedule an inspection. We’ll show you the camera footage and tell you honestly whether cleaning is needed.
Yes. We’ve developed techniques over thirteen years in San Francisco for accessing retrofit ductwork through floor chases, wall cavities, and crawl spaces that newer cities never encounter. Our Rotobrush and Nikro equipment includes flexible shafts and miniaturized heads designed for exactly these tight clearances. We won’t damage plaster or lath to reach your ducts - we find the access points that exist and work with them.
More common than in inland California, yes. The combination of stagnant airflow, cool metal surfaces, and moisture from the marine fog layer creates conditions where mold can establish itself without the drying effect of regular HVAC use. Our camera inspections focus on spotting biological growth, and we discuss sanitizing options only when we find evidence of it. We don’t sell treatments you don’t need.
We typically schedule within 24 to 48 hours for standard appointments, and we maintain emergency availability for situations like post-fire restoration or severe airflow blockages. A live person answers our phones at all hours, so you won’t wait for a callback. If you’re in 94122, 94123, 94124, or 94125, we’re already routing vans in your area.

What San Francisco Customers Say
"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I did not need."
- Marcus Robinson"Fair price and thorough work. They ran about an hour and a half past the estimated finish, so do not schedule anything tight after them."
- Malik Hampton"Did the dryer vent while they were here for a small add on price. The dryer finishes a load in one cycle now instead of two."
