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.

Most air duct repairs in Redwood City run between $220 and $480 for a typical single-run fix; full replacement jobs range higher, and we put a written price in your hand before any work starts.

Why Linden Air Duct Cleaning Is Redwood City’s Preferred Air Duct Repair Company
We know the houses here because we work on the houses here. The Redwood Shores tract homes with flex duct sagging into bay mud, the Central Redwood City bungalows with sheet metal nailed together before Eisenhower was president, the Emerald Hills custom builds with ducting snaking through steep attic channels. That local knowledge matters when a home’s duct failure is tied to the ground it sits on, as it so often is here.
Our Air Duct Repair teams arrive with a name and photo sent to you before the visit, a photo ID badge shown at the door, and a background-checked technician in a clean, marked uniform. No anonymous van pulling up. You know exactly who is stepping inside your home before they ring the bell. Marcus Veale built this standard, and every repair we do in Redwood City carries it.
Every job gets the 365-Day Done Right Promise in writing. If a covered repair fails within one year, we come back and make it right at no charge. That’s not a promotional offer. It is a standing commitment, on paper, since 2004.
HVAC Duct Installation in Redwood City
HVAC Duct Installation in Redwood City means running new ductwork where what you have now is too far gone to patch, or where a remodel changed the layout of the home. Think of a Carriage Square rancher where a converted garage now needs supply and return lines, or a Mount Carmel home where fifty-year-old galvanized runs have rusted through at the seams. When we install, we size the runs to the blower, seal every joint, and hang the duct properly, not just adequately.
Full-System Duct Layouts
A new layout for a typical 1,800 to 2,400 square foot Redwood City home runs from $2,800 to $6,500 depending on crawl space access, the number of registers, and whether we’re working around existing framing. We quote that price before we touch anything, and it does not change when the job gets harder than expected.
Replace the Run, Not the Whole System
Most often, one or two failed runs are the problem, and the rest of the system is fine. In those cases we install only what actually needs replacing. That’s the honest approach, and it keeps a $800 job from getting bundled into a $6,000 upsell you didn’t need.
Air Duct Replacement in Redwood City
Air Duct Replacement in Redwood City is the right call when the ductwork itself is beyond repair, which we see constantly in specific pockets of this city. Redwood Shores homes from the 1970s and 1980s were built on dredged bay-fill tidelands, and the ground beneath them shifts in a way the upland Peninsula never does. Decade after decade, hangers loosen, flex runs kink, and conditioned air spills into the crawl space. Replacing that sagged, collapsed line is a real structural repair, not a tune-up.
When Replacement Makes More Sense Than Patching
If a run is torn along more than a few feet, crushed flat in a tight crawl, or saturated with moisture to the core, patching it with tape is just a holding action that fails again within a season or two. Replacement runs for a typical 10 to 20 foot span in Redwood City cost between $350 and $900 installed, including mastic sealing and hangers.
What We Pull Out of the Old Runs
This is where it gets telling. In bay-facing parts of town, the old flex duct we remove is often heavy with condensed moisture, its insulation waterlogged, its inner liner speckled with microbial growth. New duct, properly hung and sealed, usually resolves the damp, “dirty socks” smell from the registers entirely. No fogging treatment needed.
Trusted Brands We Service in Redwood City
The equipment and materials we install come from names HVAC contractors and facility managers know well: Nikro extraction machines, Honeywell and Aprilaire filtration components, and Abatement Technologies HEPA systems. We keep a rolling stock of common duct sizes, fittings, hangers, and mastic sealant ready for Redwood City jobs, so a repair later in the day doesn’t mean waiting for a parts shipment from out of state. If it’s a bonded-core flex duct problem in Redwood Shores or a 6-inch galvanized run in Palm Park, we’ve got what the job takes on the truck.
Common Air Duct Repair Problems We See in Redwood City Homes
- Bay-fill flex duct failure in Redwood Shores. Compressible bay mud shifts foundations gradually over decades, loosening hangers and letting flex duct sag, kink, or disconnect from boots entirely. The result is conditioned air pouring into the crawl space while your living room stays stuffy.
- Salt-laden humidity in bay-facing duct runs. Homes near the water pull humid, salty air into crawl spaces. That moisture wicks into duct insulation and interior surfaces, encouraging microbial growth that a quick fogging treatment won’t remove from the duct substrate.
- Crushed and separated sheet metal in Central Redwood City. Tight, low crawl spaces under 1940s and 1950s bungalows mean joints separate and runs get crushed by years of poor access. Airflow drops at the registers, but the homeowner usually can’t see why.
- Debris-loaded supply and return ducts from heavy AC cycling. Redwood City’s fog-sheltered microclimate means homeowners run central AC far more than neighbors in San Carlos or Menlo Park. That cycles dust, pet dander, and skin cells through the duct walls at a rate that surprises people.

FAQs About Air Duct Repair in Redwood City
Redwood Shores was developed on dredged bay-fill tidelands beginning in the late 1960s, which means thousands of homes sit on high-water-table ground over compressible bay mud. That mud shifts slowly over decades, loosening duct hangers and letting flex duct sag, kink, or disconnect from boots entirely. Inland Peninsula towns like San Carlos and Menlo Park sit on firmer native soil, so their duct runs fail from age and material breakdown, not from ground movement. If your Redwood Shores registers feel weak while the crawl space feels cold, there’s a good chance the conditioned air is escaping into the dirt. Call (980) 447-2498 and we’ll camera-inspect the run to see exactly where it’s failing.
No. A fogging treatment sprays a chemical mist into the duct interior, but it does not remove the moisture-laden dust, salt residue, or settled organic matter where microbial growth actually takes hold. In bay-facing Redwood Shores and Redwood City homes, the root cause is often condensation against interior duct walls, and the fix is source removal: negative-pressure extraction with HEPA filtration, then sealing or replacing affected runs so moisture stops wicking into the material. A fogging treatment without addressing moisture is a temporary smell mask. Anyone who tells you otherwise is selling you the upsell, not the solution. Call (980) 447-2498 and we’ll tell you honestly whether your ducts need cleaning, sealing, or replacement, never the fog.
Yes, and it comes down to two local conditions. First, Redwood City sits in a topographic bowl shielded from the marine fog layer, so it’s measurably hotter than San Carlos, Menlo Park, or Daly City in summer. That means central AC gets cycled hard here, which pulls far more particulate through the ducting. Second, bay-facing sections like Redwood Shores take salt-laden humidity off the bay, which accelerates condensation inside duct runs. Together, those forces put more strain on Redwood City ductwork than on the average Peninsula home. A system that might be fine in Menlo Park can be severely loaded here. Call (980) 447-2498 for an inspection that accounts for your specific neighborhood conditions.
Replace flex duct when it has sagged, kinked, torn, or disconnected from the boot, or when the inner liner has become saturated with moisture. No cleaning protocol fixes a physical failure. In Redwood Shores crawls, we find flex runs that have dropped out of their hangers and now sit against bay-mud soil, wicking moisture through the outer jacket. Cleaning that run is pointless; replacing it is the repair. A good rule of thumb: if the duct’s shape has failed, the duct has failed. We’ll camera-inspect suspect runs and show you the video before recommending replacement. Call (980) 447-2498 for a straight answer on what you actually need.
You should get proof, not promises. At Linden, every repair ends with a camera inspection of the finished work, before-and-after photos, and a written 365-Day Done Right Promise stating what was done, what’s covered, and for how long. We seal joints with mastic, not duck tape, and we re-hang runs on proper saddles and straps anchored to structure, not left resting on the ground. If a covered repair fails within one year, we come back at no charge. That’s how you know. Call (980) 447-2498 and we’ll walk you through exactly what a Redwood City repair includes, line by line.
