Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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 Air Duct Cleaning Across Redwood City
Air duct cleaning in Redwood City typically costs between $400 and $900 for a full residential system, depending on home size, the number of returns, and how long it’s been since the last cleaning. Most jobs take four to six hours and we schedule within a few days of your call. If you’re in Redwood City and your registers are blowing dust, or you’ve noticed a musty smell when the AC kicks on in one of those heat spells Redwood City gets that the rest of the Peninsula doesn’t, the ducts are usually the first place to look. Call (980) 447-2498 and we’ll give you a written price before any work starts.
We’ve worked in Redwood City long enough to know that a 1950s ranch near Sequoia High School has very different duct problems than a 1970s tract home out on Redwood Shores. One sits on solid ground with old sheet-metal trunk lines. The other sits on bay fill with flex duct that sags and disconnects. Neither one gets fixed properly by a company that just shows up with a shop vac and a coupon. The difference is in how the job is done, which is what this page explains.
Why Linden Air Duct Cleaning Is Redwood City’s Preferred Air Duct Cleaning Company
We’ve been doing this since 2004 as part of the Threshold Group family, and Redwood City homeowners keep calling us back for one reason: we tell you who is coming to your door before they arrive. Every technician is background-checked, identity-verified, and photo-badged under the Threshold Standard. You’ll get the tech’s name and photo sent to you before the visit, and they’ll show a photo ID badge at the door. No exceptions, on every single job.
Our Air Duct Cleaning team in Redwood City works with Rotobrush and Nikro equipment, running negative-pressure extraction with HEPA filtration rather than a brush-and-vacuum shortcut that stirs debris around. We put the price in writing before any work begins, and every repair we make carries a written guarantee. If a covered repair fails within 365 days of the work, we come back at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job. Marcus Veale leads the crew, and he’s the one who makes sure the promise means something.
When you call, a live person answers. Every time. 24/7. No voicemail trees, no “press 2 for scheduling.” You’ll speak to a human who can book the visit, answer pricing questions, and tell you what to expect when the technician arrives at your Redwood City home.
Commercial Air Duct Cleaning in Redwood City
Commercial Air Duct Cleaning in Redwood City is a different animal than residential work, and it’s one of the services we handle most often for the office parks along Veterans Boulevard, the medical and dental offices near Sequoia Hospital, and the retail spaces downtown around Broadway. These jobs run larger and the pricing reflects it, typically $900 to $2,400 depending on square footage, the number of rooftop units, and whether the building has multiple zones. The work involves negative-pressure extraction across larger trunk lines, access through rooftop HVAC units, and often a phased schedule so the business doesn’t shut down while we work.
Office and Medical Buildings
Offices and clinics in Redwood City often have duct systems that run for years between cleanings, accumulating construction dust, paper fiber, and the kind of fine particulate that settles into a blower motor and shortens its life. We schedule around your operating hours and give you a written report with before-and-after photos. If you manage a medical practice, we can explain the airflow documentation part to your compliance team.
Retail and Restaurant Spaces
Restaurants downtown and retail spaces along El Camino Real have their own set of issues. Grease-laden vapor, kitchen exhaust proximity, and high foot traffic mean the duct interiors pick up a film that regular filters can’t catch. We clean what’s actually in the system, not just what’s visible at the register. You’ll get camera inspection before and after so you can see exactly what changed.
Air Duct Cleaning Services in Redwood City
Air Duct Cleaning Services in Redwood City cover a few distinct scopes, and the right one depends on your house. A full-system residential cleaning, meaning supply ducts, return ducts, the air handler, and the blower compartment, typically runs $400 to $700 for a three- or four-bedroom home. If the job includes crawl-space access, disconnected flex repair, or significant microbial growth, the price moves accordingly. We’ll give you the exact figure in writing before anything is touched.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms. Return ducts pull it back to the air handler. Both matter, and a lot of cut-rate cleanings only do the supply side because it’s what the homeowner sees. On older Redwood City homes with crawl-space returns, the return side is usually dirtier, and cleaning only half the system is like washing one half of your car.
Video Inspection and Full-System Cleaning
Before we clean, we run a camera through the runs. On a Redwood Shores home, that camera regularly finds flex duct that has sagged off its hangers, kinked, or pulled away from the register boot entirely. We’ll show you the footage. Then we clean, then we camera again. You see the before and after. That’s the only honest way to know the work was done.

Trusted Brands We Service in Redwood City
We run professional equipment from Rotobrush and Nikro, and we work with air-quality products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. That matters because a lot of Redwood City homes have older systems, and the right agitation tool for a rigid metal trunk line in a 1950s bungalow is not the same tool you want inside a 1980s flex run on bay fill. We stock the common parts locally so a disconnected boot or a failed hanger doesn’t mean a second visit. If your system needs a replacement component, we’ll tell you what it costs before we install it.
Common Air Duct Cleaning Problems We See in Redwood City Homes
- Sagged and disconnected flex duct on Redwood Shores. The bay mud beneath these homes shifts slowly over decades. Duct hangers pop, runs collapse, and conditioned air pours into the crawl space instead of your living room. You can’t fix that with a vacuum pass; the run has to be re-hung and reconnected.
- Moisture and microbial growth in fog-free but humid coastal air. Redwood City’s unique heat profile means residents run AC heavily, but bay-facing sections also get salt-laden humidity off the water. Interior duct surfaces stay damp longer. That’s where mold starts, and it’s why camera inspection matters before you pay for any cleaning.
- Old sheet-metal ductwork in 1940s-1960s ranch homes. Central Redwood City, particularly around the Roosevelt and Stambaugh neighborhoods, has original metal ducts in tight low crawl spaces. They rarely get serviced because the access is miserable. We have the equipment to get in there and do it properly.
- Debris-heavy systems from heavy AC cycling. Redwood City gets hotter than San Carlos, Menlo Park, or Palo Alto because the fog doesn’t reach it. That means your central air runs more, your ducts cycle more, and they collect more. A system that’s clean one year can be genuinely loaded five years later.
Pricing for Air Duct Cleaning in Redwood City, CA
Expect to pay $400 to $700 for a typical single-family home in Redwood City, with larger homes or homes with crawl-space access issues running $700 to $900. A commercial space usually lands between $900 and $2,400. What moves the price is the number of returns, the condition of the ductwork, whether flex runs need to be re-hung, and whether there’s microbial growth that requires more than standard cleaning. You’ll get one flat price for the whole system before work starts, not a per-vent price that balloons once the tech is in your house. Call (980) 447-2498 for a free estimate, and you’ll get a written number from the person who answers the phone.

FAQs About Air Duct Cleaning in Redwood City
Redwood Shores was built on dredged bay-fill tidelands starting in the late 1960s, so the ground beneath those homes holds a high water table, and that moisture wicks up into crawl spaces where flex duct sits. The salt-laden humidity off the bay adds to it. San Carlos and Menlo Park sit on more solid upland ground, so their ductwork stays drier. If you’re in Redwood Shores and you smell mustiness when the AC cycles, call (980) 447-2498 and we’ll camera the runs before recommending anything.
Yes, if you run central AC regularly. Redwood City’s fog-sheltered microclimate means it gets measurably hotter than most of the mid-Peninsula, and residents here run their air conditioners far more than people in San Carlos, Menlo Park, or Palo Alto. That heavy cycling pulls more air through the ducts and deposits more particulate. If you’re running AC most days from June through October, you should inspect and likely clean ducts every three to five years. Call (980) 447-2498 and we’ll tell you what we find before you commit to anything.
A real source-removal cleaning pulls debris out of the ducts using negative pressure and HEPA filtration, often with Rotobrush agitation to break material loose from the duct walls. A fogging treatment mists a chemical into the ducts to mask odor. It does not remove the source. On Redwood Shores, where moisture and microbial growth are the real issue, fogging hides the problem for a week or two and then the smell returns because the mold is still there. We don’t sell fogging as a substitute for cleaning. If your ducts need cleaning, clean them.
The compressible bay mud beneath Redwood Shores shifts gradually over decades, and that movement dislodges duct hangers, sags flex runs, and can pull runs completely off the register boots. Our tech pulled up to a 1980s tract home on Redwood Shores Parkway and found the return-side flex duct fully disconnected from the air handler boot, collapsed into the crawl space above the shifting bay mud. After reconnecting and re-hanging the run, we ran camera inspection through the supply and return ducts with a Rotobrush agitation tool under negative pressure and HEPA filtration, then reset the blower motor and verified airflow at every register. That’s a structural failure, not a cleaning issue, and the fix is to re-hang and reconnect, not to vacuum harder. Call (980) 447-2498 if you suspect your flex runs have dropped.
Yes. Homes in Emerald Hills and Farm Hill tend to be post-1960s construction with ductwork running through unconditioned attic space on steep, irregular lots, and that attic heat bakes the ducts and dries out any flex connections. Camera inspection shows us whether the runs are intact before we put negative pressure on the system, and negative pressure with HEPA filtration is how we pull debris out rather than blowing it around. The job isn’t done right without both. Call (980) 447-2498 for an exact quote on your home.
