We’ve been driving our vans through Mission District’s grid of Victorians and Edwardians since 1984. Ray Castillo built this company on showing up when we say we will, naming the price before a tool leaves the truck, and standing behind the work for 90 days without paperwork or arguing. Mission District isn’t a territory on a spreadsheet for us. It’s where we replace rusted duct fasteners on Guerrero Street, pull decades of drywall dust from gut-renovated flats near Valencia, and track moisture patterns in the fog-sheltered valley between Twin Peaks and Bernal Heights that make this neighborhood’s duct problems genuinely different from Noe Valley’s or Daly City’s.
The Mission’s warmer, sunnier microclimate tricks some homeowners into thinking moisture isn’t an issue. It is. Marine air still penetrates at night and through shoulder seasons, condensing inside cool duct runs and corroding hardware that inland systems preserve for years longer. That’s why our Air Duct Cleaning team carries stainless steel fasteners and corrosion-inhibiting coatings on every Mission District job, not as upsells, but as standard equipment for the territory.
Why Bellows Air Duct & Vent Co. Is Mission District’s Preferred Air Duct Cleaning Company
Forty-two years in this trade means we’ve cleaned ducts in the same Mission District buildings three times over as ownership changed and renovations came and went. Homeowners here know our vans. They also know we don’t bait with a $49 coupon and rewrite the invoice at the door.
Our 90-Day Done Right Promise is stamped on every job. If the work isn’t right, we return at no charge. No forms to mail, no manager to escalate, no argument. Ray Castillo put that in writing because it’s how he wanted to be treated when he hired tradesmen himself.
Calls to (844) 685-6342 are answered by a live person, 24/7. Not a voicemail tree, not an app that routes you to a call center in another state. Our background-checked, uniformed technicians arrive with camera inspection equipment from Rotobrush and Nikro, and they show you the inside of your ducts before touching them and after the work is done. The visual record belongs to you.
We know the Mission’s streets. We know which blocks have the unrenovated crawl spaces where rodents enter through rusted access panels, and which buildings went through 2010s gut renovations that loaded the original ductwork with construction debris no filter could catch. That local knowledge changes what we bring to the job and where we look first.
Our Air Duct Cleaning Services in Mission District
Residential Duct Cleaning
Most Mission District homes we service are two- or three-unit Victorian or Edwardian flats built between 1890 and 1915, with forced-air HVAC retrofitted decades later through floor joist bays and wall chases never designed for airflow. These tortured duct runs create debris-trapping dead zones that standard cleaning misses. Our residential service maps every branch with video inspection before agitation, so we’re not guessing where the buildup lives. A typical residential cleaning in Mission District runs $350-$550 for a single-unit system, $550-$850 for a full two- or three-flat building with separate furnaces.
Commercial Duct Cleaning
Commercial ductwork in the Mission spans restaurant exhaust systems on Valencia Street, retail spaces in converted ground-floor Victorians, and small office buildings with mixed-era HVAC. We clean to NFPA 96 standards for kitchen exhaust and provide written documentation for insurance and health department compliance. Commercial pricing starts around $800 for small retail systems and scales with duct complexity and access difficulty. We schedule around your hours so you’re not losing service revenue.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Mission District Victorians, these are often the retrofitted lines running through original fir-floor cavities, with irregular geometry that traps debris at every bend. We use Rotobrush contact cleaning and controlled negative air from Nikro equipment to dislodge buildup without damaging century-old lath and plaster surrounding the chases. Supply duct cleaning as a standalone service in Mission District typically runs $200-$400, though we usually recommend full system evaluation first.
Return Duct Cleaning
Return ducts pull air back to the furnace, and in the Mission’s older buildings, they’re where we most often find rodent nesting material, moisture damage, and the heaviest accumulation of demolition dust from renovation projects. Returns are also where corroded fasteners and separated joints dump unfiltered air into wall cavities, exactly like we found on Guerrero Street. Our return duct service includes joint inspection, fastener replacement with stainless hardware where needed, and mastic sealing of separations. Standalone return cleaning runs $250-$450 in this market.
Full System Cleaning
For Mission District buildings with the full range of retrofit problems, corrosion, and debris loads, we recommend complete system service: supply and return trunks, all branch lines, register boots, and the air handler cabinet. This is where our camera inspection proves its worth, documenting the before condition of every component and verifying after. Full system cleaning in Mission District typically runs $550-$950 for residential properties, with commercial quotes provided on-site after inspection.
Video Inspection
Every Bellows job includes video inspection before and after. We push a camera through your ductwork and show you what we see: rusted dampers, separated joints, rodent debris, mold staining, construction dust layers. This isn’t a sales gimmick. It’s how we build the scope of work together and how we prove it was done. In Mission District’s complex retrofit systems, video inspection often reveals problems the homeowner didn’t know existed, like the partially separated supply trunk we found on Guerrero Street near 24th.

Trusted Brands We Service in Mission District
Our trucks carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify for commercial remediation work. We stock corrosion-resistant fasteners, mastic sealants, and antimicrobial treatments sized for Mission District’s galvanized steel retrofits, not just standard new-construction materials. That inventory difference means we don’t leave your job to order parts. Most repairs and full cleanings finish in one visit because we brought what the neighborhood actually needs.
Common Air Duct Cleaning Problems We See in Mission District Homes
- Rust-jammed dampers and separated joints. Coastal salt air and fog moisture accelerate corrosion on galvanized duct fasteners and access panels in Mission District’s retrofitted Victorians. We regularly find collar screws rusted to failure, main branches pulling away from plenums, and dampers frozen in position years before inland systems show comparable wear.
- Mold growth from marine moisture condensation. The Mission’s fog-sheltered valley traps marine air that condenses inside cool duct runs during night temperature drops and shoulder seasons. Poorly sealed retrofit systems are especially vulnerable, producing musty odors after rain and visible mold staining that requires antimicrobial treatment beyond standard cleaning.
- Rodent infestation in unrenovated crawl spaces. Technicians cleaning ducts in Mission District routinely pull out nesting material, droppings, and even carcasses. Rodents enter through unsealed duct joints at the subfloor level in crawl spaces undisturbed for 40-plus years, a pattern directly tied to the neighborhood’s dense urban rodent population and abundance of century-old, unrenovated substructures.
- Construction debris from gentrification-era gut renovations. Successive waves of renovation in the Mission have loaded original ductwork with drywall dust, insulation particulate, and demolition debris that accumulates far beyond what filter changes can address. We find this especially in buildings renovated between 2000 and 2015, where contractors often neglected to protect or clean existing duct runs.

FAQs - Air Duct Cleaning in Mission District
Mission District sits lower in a fog-sheltered valley between Twin Peaks and Bernal Heights, where marine moisture lingers longer and penetrates building envelopes more persistently than in Noe Valley’s slightly elevated, better-drained terrain. The combination of salt-laden air and trapped moisture accelerates galvanic corrosion on the retrofitted steel ducts common in Mission Victorians, attacking fasteners and access panels years before Noe Valley systems show equivalent damage. We address this with stainless steel hardware replacements and corrosion-inhibiting coatings standard on Mission jobs. Call (844) 685-6342 if you’re seeing rust stains around your registers.
Every three to five years for standard maintenance, but every two to three years if your building has had recent renovation, shows signs of rodent activity, or produces musty odors after rain. The Mission’s moisture load and retrofit duct geometry accelerate debris accumulation beyond what newer buildings experience. We recently serviced a three-unit Victorian on Guerrero Street near 24th, where marine moisture had rusted collar screws to the point that the main supply branch had partially separated from the plenum, dumping debris-laden air into a wall cavity. Our tech replaced all fasteners with stainless steel hardware, sealed the joint with mastic, and applied corrosion-inhibiting spray coating. For a schedule tailored to your building, call for a free inspection.
Yes. Camera inspection before and after every job is non-negotiable company policy, not an optional add-on. We use professional video equipment to document duct condition, locate debris concentrations, identify corrosion damage, and verify complete cleaning afterward. You see what we see. In Mission District’s complex retrofit systems with hidden wall chases and floor-cavity runs, this visual record is often the only way to build an accurate scope and prove the work was done right. Estimates are free; call (844) 685-6342 to schedule.
No, it’s common but not normal, and it signals mold or mildew growth inside your ductwork from moisture intrusion. The Mission’s fog-sheltered microclimate makes this pattern especially prevalent in older buildings with poorly sealed retrofitted ducts, where night temperature drops cause condensation on cool metal surfaces. Left unaddressed, this promotes mold colonization that standard cleaning won’t resolve and that can aggravate respiratory conditions. We identify moisture entry points with camera inspection, clean affected sections with antimicrobial treatment, and seal joints to prevent recurrence. Call (844) 685-6342 for a free evaluation.
Yes. We’ve cleaned ducts in Mission District Victorians built as early as the 1890s without damaging surrounding lath and plaster. The key is controlled technique: we use flexible Rotobrush contact cleaning and adjustable negative air pressure rather than aggressive mechanical agitation, and we map duct runs with video before inserting equipment to avoid surprises. Our technicians are trained on the specific fragility of century-old building materials and carry protective shielding for finished surfaces. If your building has particularly delicate conditions, we’ll note them in the pre-work inspection and adjust our approach. Call (844) 685-6342 to discuss your specific building.
