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 Gilroy
Air duct cleaning in Gilroy typically runs $425 – $780 for a full residential system, with most homes needing the work done in a single day. If your Gilroy house smells faintly of garlic every August and September even when the kitchen is clean, the odor isn’t in your head. It’s in your ducts. Call (980) 447-2498 and we’ll tell you exactly what we find and what it costs before any work begins.
We know Gilroy’s housing stock because we work in it week after week: the 1990s tract homes east of 101, the older downtown blocks around Kern and Church, the newer builds pressing up against the foothills off Hecker Pass. Each neighborhood has its own duct problems. That’s the whole point of this page: to tell you what we actually see when we open a register in Gilroy, and what it takes to fix it right.
Why Linden Air Duct Cleaning Is Gilroy’s Preferred Air Duct Cleaning Company
Homeowners in Gilroy call us after living with duct problems for years because they didn’t know who to trust. We solve that by showing up the way we said we would. Every technician is background-checked and identity-verified under the Threshold Standard. Before your appointment, we send the tech’s name and photo. At your door, they show a photo ID badge. You know exactly who is walking into your house before they step inside.
The work itself is done with professional-grade Rotobrush and Nikro equipment, and every job receives a written price before the first tool comes off the truck. That’s not a promotion. It’s the way Linden has operated since 2004 as part of the Threshold Group family.
Marcus Veale leads our team, and he’s built the schedule around a simple rule: a live person answers the phone 24/7. When a Gilroy homeowner calls with a duct question, they speak to a human being, not a recorded menu.
Residential Air Duct Cleaning in Gilroy
Residential Air Duct Cleaning in Gilroy means source removal: we physically remove the dust, chaff, and debris from your supply and return ductwork, not just stir it around. For a typical 2,000 – 2,700 square foot Gilroy home, expect $425 – $680 depending on the number of registers and how long it’s been since the last cleaning. Homes with two full systems or heavily contaminated duct lining run higher, up to $780.
Why Gilroy specifically? The valley floor between the Diablo Range and the Santa Cruz Mountains acts like a bowl. When the late-summer garlic harvest kicks in, fine chaff from processing operations like Christopher Ranch drifts across the basin and gets pulled into HVAC intakes. Your filter catches some of it. A lot of it doesn’t stop there.
What the job actually involves
We connect negative-pressure extraction equipment to your main trunk line, then run Rotobrush and Nikro agitation tools through every supply and return run. The goal is physical removal of the dust and debris that’s adhered to the duct lining, including the garlic-tinged film that settles into supply plenums near Christopher Ranch every summer.
After the cleaning, we inspect the work with a video camera so you see the result yourself, not just a receipt. If we find disconnected or crushed runs, we’ll show you the footage and quote the repair separately before doing any work.
How often Gilroy homes need it
Most Gilroy homes do well with a full duct cleaning every 3 – 5 years. Homes within a mile or two of the garlic processing corridor, particularly the valley floor south of 10th Street, may need it more often. If you run your AC hard through 95 – 105°F summer weeks and your home is downwind of agricultural operations, a post-harvest cleaning every 2 – 3 years isn’t excessive. It’s practical.
Commercial Air Duct Cleaning in Gilroy
Commercial Air Duct Cleaning in Gilroy addresses the same particulate problem at a larger scale: offices, restaurants, clinics, and retail spaces with longer duct runs, higher return-air volumes, and more occupants breathing whatever the system is circulating. Commercial jobs in Gilroy typically start around $900 and run $1,200 – $2,800 depending on square footage, accessibility, and the number of rooftop units.
Gilroy’s commercial corridors along 10th Street and the outlets off 101 pull the same valley-floor air into their systems. Restaurants have it worse: kitchen exhaust and garlic processing dust combine with whatever the HVAC return pulls from the dining room. A dirty duct system pushes that back into the building over and over.
Supply duct and return duct cleaning
We clean both supply and return ductwork separately. Supply ducts push conditioned air into the space; return ducts pull room air back to the unit. Both collect dust, but returns often run dirtier because they’re pulling unfiltered air from occupied space. In Gilroy commercial kitchens and restaurants, return ducts can be thick with grease-laden particulate within a year.
Full system cleaning with video inspection
Every commercial job includes a video inspection before and after. You’ll see the inside of your duct runs, not just a summary on an invoice. If we find a disconnected run, a crushed section, or accumulated debris that explains why one part of your building won’t hold temperature, we document it and price the repair separately in writing.
Trusted Brands We Service in Gilroy
We clean and maintain duct systems in Gilroy homes regardless of what brand the equipment carries. Our techs work with Rotobrush and Nikro agitation and extraction equipment, and we stock common replacement components for Aprilaire and Abatement Technologies systems. If your Aprilaire filter housing is cracked or your Abatement Technologies UV unit needs a bulb, we typically handle it same-day from the truck. For full system replacements or source-removal jobs that need more than standard stock, we order locally and have parts in Gilroy within a day or two. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, and crews serve Gilroy locally throughout the week.
Common Air Duct Cleaning Problems We See in Gilroy Homes
- Garlic chaff coating supply plenums every late summer: Homes within a mile or two of Christopher Ranch and the processing corridor pull fine garlic particulate into HVAC intakes. It embeds in duct lining, and the odor returns every August until the ducts are physically cleaned.
- Crushed rigid ductwork in 1950s – 1970s downtown homes: Remodels in the older core around Kern Avenue and Church Street often pinch or crush original metal ducts behind walls. We’ve pulled crushed runs where airflow was reduced by more than half, and the homeowner thought the smell was coming from their kitchen.
- Disconnected flex duct in 1990s – 2000s tract homes: Attic runs in the subdivisions east of 101 and north of Buena Vista sag, tear, or pull loose from collars after 20 – 30 years. The system pushes conditioned air into the attic and draws wildfire smoke and chaff into the living space. Cleaning without resealing those runs does almost nothing.
- Wildfire smoke residue from the eastern corridors: When smoke from fires near Uvas Canyon or Pacheco Pass settles over the valley, your HVAC pulls it into the return side and embeds it in duct lining. Months later, the smoke smell returns every time the blower cycles on.
Pricing for Air Duct Cleaning in Gilroy, CA

FAQs About Air Duct Cleaning in Gilroy
The odor comes from fine garlic chaff pulled into your HVAC intakes during the late-summer harvest and processing season, which then embeds in your duct lining. A homeowner on Kern Avenue called us for exactly this: every time the AC kicked on, the house smelled like a pizzeria. Our tech ran a camera inspection and found the original 1960s rigid ductwork had a crushed run behind a remodeled wall, and the supply plenum was coated with decades of garlic-tinged dust. We set up negative pressure with our Rotobrush and Nikro agitation tools, performed source removal, then sealed the crushed section with mastic. The odor was gone by the time we packed up. Call (980) 447-2498 if your house smells the same way every summer.
Yes, and not because of your housekeeping. Homes built during Gilroy’s 1990s and 2000s tract expansion east of 101 are now 20 – 30 years old, and the original flex duct in the attics of those homes is at the end of its expected service life. We routinely find flex duct that has sagged, torn, or pulled loose from its collar, sending conditioned air into the attic and pulling valley-floor dust and garlic chaff into the living space. If you haven’t cleaned or inspected the ductwork, you’re not just dealing with accumulation. You may be dealing with open breaches. Call us at (980) 447-2498 and we’ll run a video inspection first.
We can, with the proper handling. Gilroy’s older downtown homes from the 1950s – 1970s sometimes have original rigid ductwork with asbestos-containing duct insulation. When we encounter it, we do not disturb or agitate it. Cleaning is limited to the interior surface of the duct, using negative pressure and agitation tools that do not contact or damage the exterior insulation. If we determine that damaged asbestos insulation needs removal, we’ll tell you honestly and recommend a licensed asbestos abatement contractor. We won’t touch it ourselves, and we’ll document exactly what we saw. Call (980) 447-2498 and ask for Marcus Veale if you own one of these older homes.
Source removal means physically extracting the dust, chaff, and debris from inside the duct, not just brushing it loose and letting it get pulled through the system. In Gilroy, this matters because garlic harvest dust and wildfire smoke particulate embed in duct lining in a way that a vacuum-and-brush surface pass won’t resolve. A standard cleaning without source removal leaves the odor-causing film behind, and the smell returns every August. Source removal with proper agitation and negative pressure is the only method that gets the garlic chaff out of the plenums and duct lining for good. Call (980) 447-2498 for an honest assessment of your system.
Every 3 – 5 years for most homes. Homes downwind of the garlic processing corridor, particularly along the valley floor south of 10th Street, may benefit from a cleaning every 2 – 3 years because of the seasonal chaff load. Homes near Uvas Canyon or the Pacheco Pass corridors that see wildfire smoke every fall should also be on the shorter interval. If you’ve never had the ducts cleaned and your home is more than 15 years old, start with a video inspection and go from there. Call (980) 447-2498 and we’ll tell you what we see before we recommend anything.
