That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Dryer Vent Cleaning Across San Francisco
Dryer vent cleaning in San Francisco typically costs between $149 and $279 for a standard single-family home with a straight or gently curved vent run. Older buildings with light-well or courtyard terminations usually land higher because the run is longer and packed withlint. We schedule every job with a live arrival window you can track from your phone, and the price is written down before any work starts. If you live in the Richmond, the Mission, Noe Valley, or anywhere else across San Francisco, call (737) 727-2314 and a real person answers.
Cardinal Air Duct Cleaning knows San Francisco’s housing stock in a way a generic duct company doesn’t. We’ve worked in Victorians on Ashbury Street, Edwardians in the Sunset, and mid-century flats in Glen Park. Each building type has its own vent routing, its own lint traps, and its own way of hiding a problem until the dryer starts taking two cycles to finish a load.
Why Cardinal Air Duct Cleaning Is San Francisco’s Preferred Dryer Vent Cleaning Company
We’re part of the Relay Home Co. family, founded in 2005, and every location operates under The Relay Visibility Guarantee. That means you get a live trackable arrival time, before-and-after photos of your own vent run, and a digital invoice payable by link. No vague windows. No wondering who’s showing up. You’ll know your technician’s name before they knock.
San Francisco customers call us because we answer the phone. A live person, 24/7. No voicemail loops, no phone tag. When you call (737) 727-2314, you’ll talk to someone who can book the job, answer questions about lint build-up in older buildings, and tell you honestly whether your vent actually needs cleaning right now or can wait.
Every technician arrives in uniform and has passed a background check. The equipment is professional-grade: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. This isn’t a shop-vac on wheels. It’s the same class of equipment used in commercial kitchen exhaust work, sized for residential vent runs.
And every job, without exception, is backed by the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it applies to every booking, not select ones.
Dryer Vent Cleaning Service in San Francisco
Dryer Vent Cleaning Service in San Francisco means something specific here that it doesn’t mean in most other cities. In a typical Bay Area suburb, the vent run is a short straight pipe through an exterior wall. In San Francisco, thousands of pre-war buildings route the dryer vent through a light well, interior courtyard, or side alley. Those runs are longer, often horizontal in sections, and they collect lint in places you’ll never see from the laundry room. A proper cleaning here starts with a camera inspection of the whole pathway, then uses rotary agitation and negative-pressure extraction to pull the loosened debris into a HEPA-filtered vacuum, not back into your living space.
For a standard San Francisco home, expect to pay $149 to $279. If the run is long, has multiple bends, or terminates in a light well that requires special ladder access, the price can reach $349. The written quote you get before we start reflects the actual run, not a guess.
Camera Inspection Before Anything Else
We don’t start by shoving a brush into a vent we haven’t seen. A small camera goes through the full length of the run first. That’s how we find sagging flex duct, hidden blockages, bird nests, and screw penetrations from old remodels. In San Francisco, where a lot of laundry rooms were added decades after the building went up, the vent path is rarely what the floor plan suggests.
Lint Removal That Actually Removes It
After the inspection, we run rotary agitation tools through the run to break up compacted lint, then pull everything out under negative pressure with a Nikro HEPA vacuum. You’ll see the before-and-after photos of your own vent when we’re done. If the run has a hard blockage, like a squirrel cache or a failed flapper, we’ll show you that too and give you a written price to fix it before we touch it.
Dryer Vent Installation in San Francisco
Dryer Vent Installation in San Francisco usually means replacing old flex duct with rigid metal pipe, or rerouting a vent that terminates in a bad spot. Many older buildings here have flexible foil duct snaking through walls and ceilings. That stuff catches lint at every ridge, and it’s a fire hazard. Rigid duct with a smooth interior moves air faster and holds far less debris. A typical installation or reroute runs $280 to $520, depending on run length, access, and whether we’re replacing the termination cap too.
When a run is beyond saving, or when a homeowner is renovating a laundry closet, we install new rigid duct, seal the joints properly, and route the termination to code. In San Francisco, that often means working with light-well or courtyard terminations, which require a specific cap design to keep rain and birds out while still exhausting properly.
Vent Rerouting for Older Buildings
Some San Francisco buildings have vent runs that were never correct in the first place. A common one: a run that dips before rising to the termination, creating a condensation trap that turns lint into a solid mat. Rerouting that run so it slopes properly eliminates the trap and dramatically reduces future build-up. We’ll give you a written price for the reroute before any work starts.
Vent Cap and Bird Guard Replacement
If your vent terminates in a light well or courtyard, the cap takes weather and bird pressure constantly. We replace damaged caps and install bird guards that keep starlings and sparrows out without restricting airflow. In dense San Francisco neighborhoods, an uncapped vent is an open invitation. A guard costs far less than extracting a nest and rebuilding the damaged run.
Trusted Brands We Service in San Francisco
We stock and service parts from the brands San Francisco homes actually have. Dryer vent runs from Whirlpool, LG, Samsung, Maytag, GE, and Kenmore are all in our service scope, as are dedicated laundry exhaust components from Guardsman and filtration from Aprilaire. For the cleaning itself, we run Rotobrush rotary agitation tools and Nikro HEPA vacuums. If your vent cap or termination needs replacing, we typically have common Guardsman caps in the van, which means no waiting on a shipped part for most San Francisco jobs.
Common Dryer Vent Cleaning Problems We See in San Francisco Homes
- Light-well and courtyard terminations. If your vent exits into a light well, it’s not venting freely into open air the way a suburban wall exit does. Lint accumulates faster, moisture stays longer, and the run is usually longer. We camera-inspect the full run before recommending any cleaning scope.
- Sagging flex duct inside the wall cavity. In older buildings, we regularly find foil flex duct that has sagged in a horizontal run between joists. Lint catches in the ridges, then compacts into felt. The dryer works harder, and the vent becomes a fire hazard. The fix is replacing the flex with smooth rigid duct.
- Bird and rodent activity in uncapped vents. Sparrows and starlings love an open dryer vent in San Francisco, especially one that opens into a quiet light well. Nests can block the run completely. We remove the nest, clean the run, and install a bird guard so it doesn’t happen again.
- Long runs with multiple bends. A vent run in a Marina District flat might travel twenty-five feet with four elbows before it reaches the termination. Every bend is a place lint slows down and drops out of the airflow. Those runs need cleaning more often than a short direct run.
We were called to a three-unit building on Ashbury Street in the Haight-Ashbury where the ground-floor tenant said the dryer was taking two cycles to dry a normal load and the laundry room smelled faintly of scorched lint. A camera inspection showed flex duct sagging in a horizontal run behind the garage, packed with several years of felted lint the tenants couldn’t reach from the trap. We switched the run to rigid duct with a smooth interior, cleared it with agitation tools under negative pressure and HEPA filtration, and the drying time dropped back to a single cycle.

FAQs About Dryer Vent Cleaning in San Francisco
Every 12 to 18 months for most San Francisco homes. If your building has a long run, a light-well termination, or you share a laundry room with multiple units, clean it every 12 months. If you notice the dryer taking two cycles per load, the vent is already restricting airflow and needs attention now. Call (737) 727-2314 and we’ll help you figure out your interval.
Yes. Light-well terminations are one of the most common configurations we work with in San Francisco. The access is different from a street-level exit, sometimes requiring ladder work from an upper floor or courtyard, but the cleaning process is the same: camera inspection first, then agitation, then HEPA vacuum extraction. We’ll quote the price before we start, flat, for the whole run.
We charge one flat price per dryer vent run. You’ll never get a per-vent or per-outlet breakdown from us. The written quote covers the entire run from the dryer connection to the termination, including the inspection, cleaning, and photo documentation. That’s the whole job, no line-item games.
We schedule every job with a live trackable arrival window, but we don’t promise same-day service. Rushing a dryer vent cleaning in San Francisco means fighting for parking, squeezing equipment through tight stairwells, and cutting corners on the camera inspection. We’d rather schedule you a day or two out and do the job right. Call (737) 727-2314 and we’ll give you the next available window.
A camera inspection of the full run, rotary agitation to break up compacted lint, negative-pressure HEPA extraction to pull debris into a vacuum instead of your laundry room, and before-and-after photos of your own vent. If we find a problem, like sagging duct or a bird nest, we’ll stop and show you a written price to fix it before touching anything else. That’s the entire process, from our San Francisco Bay Area dispatch office to final invoice.
