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.
Fast, Reliable Air Duct Repair Across Los Gatos
Air duct repair in Los Gatos usually costs between $450 and $2,800 depending on whether we’re sealing a few disconnected joints, replacing a failing flex run, or rebuilding the plenum, and most jobs are finished in a single visit. We work throughout Los Gatos, from the downtown craftsman streets to the hillside lots above Kennedy Road and Summit, and we schedule around your day, not ours. If you’ve got a musty smell blowing from the registers, rooms that never heat or cool evenly, or a blower that’s pushing dust into the air, call (980) 447-2498 and we’ll get a technician out to look at it. Every job gets a written price before any work begins, and every repair is backed in writing.
Why Linden Air Duct Cleaning Is Los Gatos’s Preferred Air Duct Repair Company
Los Gatos homeowners call us because we show up the way we said we would. Before the visit, you get the technician’s name and photo. At the door, they hand you a photo ID badge and introduce themselves. That’s the Threshold Standard, and it’s been how we operate since 2004 under the Threshold Group family. No background-check gaps, no unbranded vans, no wondering who’s about to walk through your door.
Our reputation in Los Gatos comes from doing repair work that holds. Marcus Veale leads our team, and he’s built the company around a 365-Day Done Right Promise: if the repair isn’t right, we make it right, and if a covered repair fails, the second visit is free. Homeowners in Saratoga, Campbell, Cupertino, and Santa Clara call us for the same reason, but the work we do in Los Gatos specifically accounts for how different this town’s housing stock and hillside moisture really are. That local knowledge is what separates a repair that lasts from one that just quiets the symptom.
Duct Replacement in Los Gatos
Duct replacement in Los Gatos means removing failed sections of ductwork and installing new, properly sealed runs. In this town we see a lot of older flex duct that has absorbed years of crawlspace moisture or embedded wildfire ash and is no longer salvageable. Replacing it is the smarter path when the inner liner is degraded, the insulation jacket is soaked, or the connections at the plenum keep separating.
Flex-to-hard duct upgrades on hillside lots
Homes on the slope above downtown Los Gatos often route supply and return air through tight crawlspaces that sit near seasonal drainage swales. That location holds moisture longer than a flatland crawlspace ever will, and flex duct absorbs that moisture into its insulation jacket. Once the inner liner starts to break down, air leaks through and the system loses pressure before it ever reaches the bedrooms. We replace those sections with hard duct where the joist layout allows, reseal every boot, and wrap the new connections with mastic, not tape. Expect a typical hillside duct replacement in Los Gatos to run $1,200 to $2,800 depending on how many runs are involved and how much of the crawlspace needs to be accessed.
Restoring downtown homes with original ductwork
Downtown Los Gatos has a lot of 1930s through 1960s bungalows and ranch homes, many still running original or early-replacement ductwork. Those systems worked when they were sized for a furnace only, but they weren’t built for modern heat pumps or air conditioning. When interior duct liner starts to flake apart, it sends particles into the airstream, and disconnected joints dump conditioned air into the crawlspace instead of the living room. A partial duct replacement on a flatland craftsman in Los Gatos typically runs $800 to $1,900, depending on access and run length.
Ductwork Installation in Los Gatos
Ductwork installation in Los Gatos covers the full replacement of a home’s air distribution system, from the plenum outward. We see this most often in hillside homes where decades of condensation, wildfire ash, and failed liner have made patching uneconomical. When a system has multiple failed sections, it’s usually cheaper in the long run to install new ductwork than to keep chasing leaks.
Complete system replacement for hillside homes
A hillside home above Los Gatos might have duct runs routed through three separate attic sections, a foundation crawlspace, and a chase built through a hillside retaining wall. Designing and installing a replacement system in that geometry requires camera inspection first, airflow measurement, and careful planning around existing joists and drainage paths. This is not a flatland strip-mall job. A full ductwork installation in a large Los Gatos hillside home typically runs $3,500 to $8,000 or more depending on square footage and access difficulty. For a smaller downtown ranch, expect $2,500 to $5,000.
Post-wildfire full duct replacement
After the CZU Lightning Complex fire, we started getting calls from Los Gatos homeowners whose ductwork had never been cleaned but suddenly smelled like smoke every time the blower kicked on. Ash had infiltrated the intakes and embedded in the duct walls. When source removal can’t restore the duct’s integrity, full ductwork installation is the honest answer. We’ll tell you which path makes sense after the camera inspection, not before.
Trusted Brands We Service in Los Gatos
Our technicians are trained on professional-grade equipment from Nikro and we stock common parts and filters for Honeywell and Aprilaire air-quality products so Los Gatos customers aren’t waiting on a shipment from a distributor. If your system uses an Abatement Technologies filtration unit, we can service it on the same visit as your repair. The tool matters less than the person holding it, but both matter, and we don’t send a tech to a hillside crawlspace with equipment that can’t do the job properly.
Common Air Duct Repair Problems We See in Los Gatos Homes
- Hillside crawlspace moisture and mold: The Highway 17 corridor pulls cool marine air through Los Gatos, and duct runs in unconditioned crawlspaces on hillside lots stay damp far longer than flatland ductwork. That condensation breeds biological growth that eats through flex duct inner liners and forces replacement.
- Wildfire ash fouling in supply and return walls: Los Gatos sits at the base of the Santa Cruz Mountains, and the 2020 CZU Lightning Complex fire pushed fine combustion particulate into HVAC intakes across town. Ash like that keeps re-entraining every time the blower cycles until it’s source-removed under negative pressure, and in some cases the duct wall itself is too far gone to save.
- Deteriorated interior liner in aging downtown homes: Many of the 1930s – 1960s craftsman and ranch homes in the Los Gatos flatlands still carry original or early-replacement ductwork. Interior liner flakes apart and disconnected joints bleed heated air into the crawlspace, so rooms near the register get hot while the far bedroom stays cold.
- Flex duct failure near drainage swales: Hillside lots above downtown Los Gatos often route ducts near seasonal drainage lines. After a dry fire season followed by a wet El Niño winter, we routinely pull flex sections that show both smoke particulate fouling and active mold on the same job. Flatland cities simply don’t produce that combination.
Pricing for Air Duct Repair in Los Gatos, CA
You should know what to expect before you call. A basic duct joint reseal or minor plenum repair in Los Gatos runs $350 to $750. Replacing a single failed flex run with hard duct in an accessible crawlspace runs $800 to $1,600. Full duct replacement on a hillside home starts around $3,500 and climbs based on how many crawlspace and attic sections the system passes through. What changes the price most is access: a downtown Los Gatos crawlspace with hard dirt and exposed joists is fast; a hillside crawlspace near a drainage swale with tight clearances takes longer. We put the price in writing before any work begins and we never change it after the fact. Call (980) 447-2498 for a free estimate and we’ll give you an exact number for your system.

FAQs About Air Duct Repair in Los Gatos
Hillside Los Gatos homes route ductwork through unconditioned crawlspaces and multi-level attic sections that hold moisture longer than flatland systems in Campbell or Santa Clara, and the marine air coming through the Highway 17 corridor keeps relative humidity persistently elevated. Add in post-wildfire ash from the Santa Cruz Mountains and you get duct runs that fail from biological growth, particulate fouling, and liner degradation all at once. That’s why we camera-inspect every hillside repair before quoting, and why patching a single leak without checking the rest of the run usually sends us back six months later. Call (980) 447-2498 and we’ll walk through what your specific system actually needs.
Yes. Los Gatos has several multi-unit buildings downtown and along Los Gatos Boulevard where duct risers are shared, and repairs in those buildings require coordination with the HOA or property manager, scheduled access windows, and careful isolation so one unit’s repair doesn’t push debris into a neighbor’s system. We’ve worked with property managers across Los Gatos to schedule repairs during approved hours, and we always confirm unit access and liability terms before the visit. If you’re an owner in a shared building, call (980) 447-2498 and we’ll help you figure out what’s on your side of the wall versus the association’s.
We plan for it. Downtown Los Gatos has narrow residential streets and tight driveways, and our technicians carry compact, modular equipment that fits through side gates and into crawlspace access hatches rather than requiring a trailer parked directly at the curb. We use Nikro negative-pressure units that break down into sections, and we’ll coordinate a short parking window or loading-zone use with you before the appointment. If your street has no space at all, we’ll walk the equipment in from the nearest legal spot and still complete the job in one visit.
Wildfire-ash duct remediation in Los Gatos involves source removal under negative pressure with HEPA filtration, not just blowing a shop vac through the registers. We seal the supply and return openings, connect a negative-air machine to draw the system into a constant vacuum, and use agitation tools to physically release particulate from the duct walls while the airstream carries it through the filter. In hillside systems we also camera-inspect afterward to check for liner damage and moisture. If the ash has embedded into compromised liner material, removal alone won’t solve the problem and we’ll recommend duct replacement for the affected sections. Call (980) 447-2498 if you’ve been smelling smoke every time the blower cycles.
Repair makes sense when the failure is localized: a disconnected joint, a single failed flex section, or a plenum leak. Full replacement makes sense when multiple sections have failed, the interior liner has degraded across the system, or moisture and ash fouling have compromised enough of the duct wall that patching becomes more expensive than starting fresh. We were called to a split-level home off Kennedy Road where the uphill supply and return ducts ran through a foundation crawlspace sitting near a seasonal drainage swale. The homeowner’s complaint was a musty smell blowing through the registers. Using camera inspection and agitation tools under negative pressure with HEPA filtration, we found three flex duct sections loaded with both wildfire ash and active mold. We replaced those runs with hard duct and resealed the boots, and the odor cleared within a day or two. If we’d only patched the visible leak, the odor would have returned within weeks. That’s what we mean when we say we’ll tell you the honest answer after the camera inspection, not before. Call (980) 447-2498 for a free estimate and we’ll show you exactly what’s inside your ducts.
