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.

Gilroy’s not like Morgan Hill or Los Gatos. The garlic fields surrounding the city, the clay soils that track in on boots and paws, and the dense housing stock downtown and near Las Animas Park all create a debris profile we see nowhere else in the South Bay. Our technicians arrive with Rotobrush rotary systems, Nikro negative-air machines, and the filtration tools to handle it. We price every job in writing before we start, and every repair carries our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Gilroy’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Gilroy customers know what The Garrison Standard means: arrive inside the window, price it before we touch it, finish by the book, leave the site clean. Roy Castellanos leads our operation, and our background-checked, uniformed technicians don’t subcontract to random crews.
Our phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues. When you schedule in Gilroy, you get a real arrival window and a written price that doesn’t move when the van pulls up. If the work fails within a year, we return and make it right at no charge. That includes a free second visit, not a negotiation.
We know the parking constraints on Monterey Street downtown, the tight side yards in the 1970s tract neighborhoods, and the shared wall chases in condo buildings near Las Animas Park. That local knowledge means we bring the right equipment access plan, not excuses about why the job got half-done.
Air Duct Cleaning Services in Gilroy
Air Duct Cleaning Services in Gilroy address a debris mix you won’t find in coastal cities. Our process starts with a video inspection of your trunk lines and branch ducts, then we set up negative pressure at the air handler using HEPA filtration to capture what we agitate loose. For a typical single-family home in Gilroy, expect $350 – $550. Larger homes or systems with heavy agricultural debris buildup run $500 – $650.
Residential Duct Cleaning
Most Gilroy homes we serve are suburban tract builds from the 1970s through the 2000s, many with original flex duct that’s sagged, torn, or become a rodent pathway. We camera-inspect first, then use rotary brush agitation combined with negative-air source removal. The price is written before we start.
Commercial and Multi-Unit Cleaning
Gilroy’s apartment and condo buildings often share dryer vent stacks through a single wall chase. We clean the full common run, not just your unit’s segment. One unit’s lint fire risk sits behind another unit’s wall, so partial cleaning leaves the hazard in place.

HVAC Duct Cleaning in Gilroy
HVAC Duct Cleaning in Gilroy requires handling the region’s unique seasonal cycle. The July – September garlic harvest fills the air with fine particulate matter that pulls into ductwork through cracks and gaps, then combines with clay soil tracked in from nearby open land. Without ocean breeze to disperse it, the debris settles and compacts. A typical HVAC duct cleaning in Gilroy runs $400 – $600 for full supply and return systems.
Supply and Return System Cleaning
We separate supply ducts (the ones pushing conditioned air to your rooms) from return ducts (the ones pulling air back to the handler). In Gilroy’s older downtown bungalows, we’ve found clay soil caked past the registers and rodent breaches in flex runs. We seal what we find, then clean both sides of the system.
Video Inspection and Documentation
Before and after photos from our camera systems show you what came out. In Gilroy’s market, where agricultural debris creates a distinctly gritty, organic buildup, that documentation matters. You’ll see the difference between surface dust and the packed field particulate we actually removed.
Trusted Brands We Service in Gilroy
Our equipment roster includes Rotobrush rotary brush systems for agitation, Nikro negative-air machines for source removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t use hardware-store vacuums with a brush attachment. For Gilroy’s heavy debris loads, we need commercial-grade extraction and HEPA containment. The same brands supply commercial crews nationwide, and we maintain local parts availability so repairs and filter swaps don’t sit in backorder. When a Gilroy customer needs a Guardsman filtration upgrade or an Aprilaire media replacement after a heavy harvest-season cleaning, we stock it or source it fast.
Common Air Duct Cleaning Problems We See in Gilroy Homes
- Garlic harvest odor penetration. During July through September, fine particulate from the surrounding fields pulls into ductwork through gaps and cracks, leaving a smell that source removal alone won’t fix. We add deodorizing treatment specific to organic agricultural residue.
- Clay soil compaction in older ductwork. Downtown bungalows off Monterey Street and nearby neighborhoods often have original galvanized or early flex duct systems. Clay soil tracked in from open land packs into low spots and past registers, restricting airflow and becoming a grinding abrasive.
- Shared dryer vent fire risk in condos and apartments. Stacked buildings throughout Gilroy route multiple units through a single wall chase or roof run. Cleaning only your segment leaves your neighbor’s lint in the shared pathway. We access and clear the common run.
- Seasonal recontamination after one-time cleaning. A single cleaning before harvest season ignores the cycle. Field particulate re-enters within weeks through existing gaps. We identify and seal breaches, and we can schedule follow-up during or after harvest.
Pricing for Air Duct Cleaning in Gilroy, CA
Whole-home air duct cleaning in Gilroy runs $350 – $650 depending on system size, access difficulty, and debris load. A typical 1,500-square-foot tract home with standard flex duct and moderate buildup falls in the $350 – $450 range. Older downtown bungalows with galvanized steel, heavy clay compaction, or rodent damage run $500 – $650 due to the extra agitation time and sealing work.
We do not quote per-vent prices. That structure invites bait-and-switch tactics: a low teaser rate that balloons once the crew counts registers inside your home. Our price is one flat rate per system, agreed in writing before work starts. The estimate is free. Call (361) 326-5060.
Factors that move the price: system size (more ducts, more time), access difficulty (tight crawlspaces or attic runs common in older Gilroy homes), debris severity (harvest-season organic loads require more filtration cycles), and whether we find breaches that need sealing before cleaning is effective.

FAQs About Air Duct Cleaning in Gilroy
The July – September garlic harvest releases fine particulate matter that penetrates ductwork through gaps and cracks, leaving organic residue with a lingering odor. Morgan Hill sits farther from the densest garlic fields and catches more coastal airflow that disperses debris. Gilroy’s inland position and lack of ocean breeze let that particulate settle and concentrate. Call (361) 326-5060 if you’re smelling harvest residue in your bedrooms.
Multiple units route exhaust through a single wall chase or roof run, so lint from one unit accumulates in the shared pathway behind another unit’s walls. Cleaning only your segment leaves the fire hazard in place. We access the common run and clear the full stack. Call (361) 326-5060 to schedule a full-building or single-unit assessment.
Yes. We plan equipment access before arrival and bring portable negative-air units when truck-mounted vacuum reach is compromised. In an older downtown bungalow off Monterey Street, our techs have worked with driveway constraints and still achieved full-system source removal. Call (361) 326-5060 and we’ll confirm access for your specific property.
Summer temperatures exceeding 100°F cause duct expansion, while cool damp winters cause contraction. That cycle cracks seams and separates connections, pulling in dust, pollen, and clay soil from nearby open land. The clay packs into low spots and grinds against metal duct walls. We find and seal those breaches during cleaning. Call (361) 326-5060 for an inspection.
Gilroy’s debris is a gritty, organic mix of garlic and produce-field particulate combined with clay soil tracked in from surrounding open land. It’s denser and more abrasive than typical household dust, and the organic component can harbor odor. Standard vacuuming without agitation and HEPA containment won’t remove it completely. Call (361) 326-5060 for a cleaning that addresses the actual debris in your system.
