We’ve been working in San Francisco’s Victorian and Edwardian row houses since 2005, and we’ve learned that dryer vent problems here don’t look like they do in newer cities. The same fog that rolls through the Outer Sunset and Richmond districts keeps vent runs damp year-round. The same century-old floor-furnace chases that heat flats in the Inner Sunset and Cole Valley often share duct pathways with dryer vents in ways that confuse standard cleaning approaches. Our crews know the difference between a modern 4-inch rigid run and a tee’d stub off a converted gas grate, and we camera-verify every clean before we seal it back up.
Dispatch and scheduling are coordinated from our San Francisco Bay Area office, and crews serve San Francisco neighborhoods directly. Whether you’re in a stucco 1920s build in the Richmond or a painted lady in Alamo Square, we’ll walk you through what we find, show you the camera footage, and give you one flat price per system before we touch a tool.
Why Morton’s Air Duct Cleaning Is San Francisco’s Preferred Dryer Vent Cleaning Company
San Francisco homeowners call us back because we treat their homes like we treat our own. Our technicians wear shoe covers and lay drop cloths from the moment they walk in. They use quieter tools during nap hours. They notice the dog on the floor and work around it. Every job is backed by our 365-Day Done Right Promise, stamped on every invoice, not just offered when asked.
We’re part of the Cedarwell family of independently owned companies, and we hold ourselves to the Cedarwell Care Promise on every single visit. That means a written price before any work starts, every time, with no exceptions. It means background-checked, uniformed technicians who work to the C.A.R.E. values. It means a photo of the clean-up before the crew leaves, so you can see your home was left better than they found it. And it means a live person answers the phone 24/7, not a voicemail, not a chatbot.
Our reputation in San Francisco is built on specifics. We’ve cleaned dryer vents in Victorians where the run hadn’t been touched since the floor furnace was converted in the 1980s. We’ve found crushed flex duct retrofitted into century-old framing with sharp bends that trapped lint at every crimp. We’ve seen fog-damp lint clumped solid in Outer Sunset runs that a quick visual check would have called clear. We document what we find, explain what it means, and fix it properly.
Dryer Vent Cleaning Company in San Francisco
Dryer Vent Cleaning Company services in San Francisco address a specific set of problems that don’t exist in newer construction markets. A typical dryer vent cleaning here runs $180-$340 for a standard rigid or semi-rigid run with accessible termination, while jobs involving floor-furnace chase cleanouts, bird guard installation, or vent rerouting through century-old framing range from $400-$650. Most San Francisco homeowners need cleaning every 12-18 months, though homes with pets, heavy laundry use, or shared floor-furnace pathways may need attention sooner.
Our process starts with a camera inspection of the full run, not just the accessible sections. We use Rotobrush agitation tools and Nikro negative-pressure HEPA extraction systems to remove compacted lint without blowing debris into your living space. For older homes with original floor-furnace chases, we check whether the dryer vent shares a pathway with converted heating stubs, a configuration we see regularly in the Inner Sunset and Cole Valley.
What the Clean Includes
We clean the full vent pathway from the dryer connection to the exterior termination, including the transition duct behind the machine. We remove and clean the exterior bird guard or vent cap, check the backdraft damper for proper operation, and verify airflow with a calibrated anemometer. If we find disconnected, crushed, or improperly sloped sections, we’ll show you the camera footage and quote the repair separately before proceeding.
When to Schedule
Schedule when drying times creep past 50 minutes per load, when the laundry room feels humid after a cycle, or when you notice lint accumulating around the exterior vent termination. In San Francisco’s fog-driven climate, damp lint clumps instead of blowing free, so the warning signs often show up as moisture problems rather than obvious blockages.
Dryer Vent Inspection in San Francisco
Dryer Vent Inspection services in San Francisco are particularly valuable because so many local homes have non-standard vent configurations that a quick visual check misses entirely. A standalone inspection runs $120-$180 and includes full camera documentation of the vent run, airflow measurement, and a written report with recommendations. We recommend an inspection before buying any Victorian or Edwardian flat in the city, and annually for rental properties where tenants may not report gradual drying-time increases.
Our inspection process was built for San Francisco’s housing stock. We feed a self-leveling camera through the full run, documenting every elbow, tee, and transition. We measure airflow at the termination with a vane anemometer and compare it against the dryer’s rated output. We check for proper slope, support spacing, and termination height per California building code. And we specifically look for the floor-furnace chase configurations that are common in pre-1920s row houses but virtually unknown in modern construction.
Camera Documentation
You’ll receive timestamped video of the full run, with voice narration explaining what we’re seeing. If we find a shared floor-furnace pathway, crushed retrofitted flex duct, or moisture damage from the marine layer, we’ll show you exactly where and explain your options. No jargon, no pressure, just clear information you can use to decide what to do next.
Inspection for Real Estate Transactions
We provide written inspection reports for San Francisco home buyers and property managers, with specific notation of any code deficiencies or safety concerns. Many Victorian flats in the Mission and Noe Valley have dryer vents that were never permitted properly when the gas floor furnace was converted. We document what’s there, what should be there, and what it would take to bring it current.
Trusted Brands We Service in San Francisco
We clean and repair dryer vents connected to every major appliance brand, and we stock common replacement parts for San Francisco customers to eliminate wait times. Our service trucks carry Guardsman vent caps and bird guards, Abatement Technologies HEPA filtration accessories, and Nikro cleaning attachments sized for both standard 4-inch runs and the non-standard diameters we encounter in retrofitted systems. For homes needing full vent rerouting, we use Rotobrush equipment to agitate and extract debris from runs that conventional rods can’t navigate. We don’t use rental-grade tools, and we don’t guess at parts availability. If your Richmond District stucco home needs a specific termination height or your Victorian flat requires a custom backdraft damper, we’ll have it on the truck or tell you exactly when we can get it.
Common Dryer Vent Cleaning Problems We See in San Francisco Homes
- Shared floor-furnace chases in Inner Sunset and Cole Valley Victorians. Dryer vents tee’d off converted gas floor-furnace stubs create lint pathways that standard cleaning misses entirely. The old grate hasn’t been serviced in decades, and lint accumulates in the shared elbow until drying times double.
- Crushed retrofitted flex duct in century-old framing. Foil or vinyl ducting shoehorned into non-standard wall cavities with sharp bends traps lint at every crimp point. A quick visual check from the laundry room looks clear; the camera reveals the real blockage three feet in.
- Fog-damp lint clumping in Outer Sunset and Richmond runs. The marine layer keeps vent interiors moist year-round even without AC use. Lint absorbs this moisture and cakes against the duct wall instead of blowing free, creating gradual restrictions that homeowners mistake for aging dryer performance.
- Improper terminations on hillside homes in Noe Valley and Bernal Heights. Exterior vent caps installed without proper backdraft dampers allow wind-driven rain and fog directly into the run. We replace these with code-compliant terminations that seal when the dryer isn’t running.
Pricing for Dryer Vent Cleaning in San Francisco, CA
We believe you should know what to expect before you call. In San Francisco’s market, a standard dryer vent cleaning for a single-family home or flat with accessible rigid duct runs $180-$280. Homes with longer horizontal runs through crawlspaces, shared floor-furnace chases, or bird guard installation typically fall in the $280-$400 range. Complex reroutes, vent cap replacements with exterior wall work, or floor-furnace chase cleanouts with proper damper sealing run $400-$650.
What affects your price: the length and accessibility of the run, whether we need to navigate century-old framing or crawlspaces, the condition of existing materials (crushed flex duct requires more labor than intact rigid pipe), and whether we’re also installing a bird guard or replacing a damaged termination. We do not charge per vent or add trip fees. One flat price per system, agreed in writing before work starts, every time. Call (323) 918-4345 for a free estimate, or schedule an inspection for $120-$180 if you want documentation before deciding on cleaning.

FAQs About Dryer Vent Cleaning in San Francisco
Yes, it’s common in pre-1920s row houses where central forced air was retrofitted decades after original construction. The floor-furnace chase provided an existing pathway, so installers often tee’d the dryer vent into it rather than drilling new penetrations in century-old framing. It’s not ideal for airflow or safety, but it’s fixable. We camera-map the shared pathway, clean both branches with HEPA-contained extraction, and install a proper backdraft damper at the tee to prevent cross-contamination. Call (323) 918-4345 for an inspection and written quote.
The marine layer keeps your vent run damp year-round, so lint clumps and adheres to the duct wall instead of blowing free. A quick rod-out from the exterior or lint-trap vacuuming doesn’t remove this adhered material. We use Rotobrush agitation with negative-pressure HEPA extraction to dislodge fog-compacted lint, then camera-verify the full run is clear. Most Outer Sunset customers see drying times drop to a single 45-minute cycle after our clean. Call (323) 918-4345 to schedule.
We camera-inspect every vent before and after cleaning. The camera reveals crushed sections, improper slopes, shared floor-furnace pathways, and moisture damage that a rod-out alone would miss or worsen. You’ll see what we see, and we’ll explain what it means for your specific system. The inspection is included in our standard cleaning price; standalone inspections run $120-$180 with full documentation.
Yes. The combination of San Francisco’s persistent coastal humidity and a cold crawlspace creates condensation inside the vent run, which wets lint and causes it to compact. Horizontal runs without proper slope also pool moisture at low points. We check for proper support and slope, install or repair condensate drainage where needed, and recommend insulation wraps for chronically cold crawlspace sections. The fix typically runs $280-$450 depending on accessibility. Call (323) 918-4345 for a specific quote.
We use Rotobrush agitation systems and Nikro negative-pressure HEPA extractors for cleaning, with Abatement Technologies filtration for contained debris removal. For repairs and replacements, we stock Guardsman vent caps and bird guards sized for both standard and non-standard duct diameters. We don’t use rental-grade equipment, and we don’t send technicians out without the tools to handle San Francisco’s retrofitted, non-standard vent configurations. Every truck is equipped for camera inspection, proper extraction, and common repairs.
