AfterHow Much Does Air Quality & Sanitizing Cost in Gilroy?
Air quality and sanitizing work in Gilroy typically runs $350 to $750 for a standard whole-home air duct cleaning and sanitizing visit, and $150 to $300 for a single dryer vent clearing. Heavily contaminated systems, post-renovation cleanup, or systems that need duct repair push the job toward $1,200 or more, because those visits take longer and require containment equipment. Every job is priced by a free written estimate, so the number you get in writing is the number you pay.
We’re duct cleaning Gilroy, and we treat duct and vent work as a craft rather than a checkbox on an HVAC invoice. That matters for pricing, because the equipment on the truck determines what a job actually takes. We run Rotobrush rotary brush systems and Nikro HEPA vacuums, and we carry Abatement Technologies filtration and negative-air units for the heavy-contamination jobs where a shop vac would just spread the problem around. If you’ve been burned by a coupon crew that blew dust toward the next register and left, this page is for you.
Key Takeaways
- Standard air duct cleaning and sanitizing in Gilroy: roughly $350 to $750.
- Dryer vent cleaning: roughly $150 to $300, and worth it for fire safety alone.
- Duct repair, when we find compromised runs: quoted separately, often $200 to $600 depending on access and length.
- Heavy contamination or post-renovation jobs with containment: $800 to $1,500.
- The estimate is free and the written price is final. Call (833) 589-9833.
Air Quality & Sanitizing Cost Breakdown (2026)
Here’s how pricing lines up for typical homes in Gilroy. These are estimated ranges for 2026, and your written estimate sets the final price.
| Service | Typical Estimated Range | What It Covers |
|---|---|---|
| Air duct cleaning (standard single-story home) | $350 – $550 | Rotary brush contact cleaning of all runs, HEPA vacuum capture, register and boot cleaning |
| Air duct cleaning (larger or two-story home) | $450 – $750 | Same process across more runs, more registers, longer trunk lines |
| Sanitizing treatment (added to cleaning) | $80 – $200 | Application after debris removal, sized to system volume |
| Dryer vent cleaning | $150 – $300 | Full length clearing, airflow measurement, exhaust verification before we leave |
| Duct repair (per section) | $200 – $600 | Reconnecting, sealing, or replacing compromised flex or hard duct found during inspection |
| Heavy contamination / post-renovation with containment | $800 – $1,500 | Abatement Technologies negative-air containment, extended cleaning, sanitizing |
| IAQ component inspection (Honeywell / Aprilaire) | Included with cleaning | Inspect filtration and IAQ equipment, clean around it, advise on upgrades |
What drives the number up: the size of the system, how much debris we pull, whether we find a collapsed or disconnected run, and whether the job needs containment. What keeps it down: a system that’s been maintained, easy attic or crawlspace access, and combining duct cleaning with dryer vent work in the same visit so the setup time is shared.
One thing worth knowing about Gilroy homes: many were built with flex duct in the attic, and in this climate, attic heat cooks that flex over the years. It sags, connections pull apart, and debris settles in the low spots. When we find that during a cleaning, we can repair it on the same visit instead of cleaning around a broken system. That’s a big part of why our scope includes air duct repair, not just cleaning.
What Affects Air Quality & Sanitizing Pricing in Gilroy
- Number of runs and registers. A three-bedroom home with 12 registers takes longer to clean well than a small two-bedroom with 6. Longer cleaning means a higher estimate, and there’s no honest way around that.
- Level of contamination. A system that’s never been cleaned, or one that took in renovation dust, needs more passes and sometimes containment. That’s the difference between a $350 job and an $800 job, and it’s usually visible in the first ten minutes on site.
- Access to the system. Attic and crawlspace access varies a lot across Gilroy’s older downtown blocks and its newer subdivisions. Tight access adds labor, and we’d rather quote it than surprise you.
- Dryer vent length and routing. A short straight vent is quick work. A long run with bends, or one that exhausts through the roof, takes more time and more care. Dryer vent blockage is a fire hazard, so we always measure airflow and confirm the vent exhausts properly before we leave.
- Repairs discovered during inspection. Disconnected flex, crushed runs, or failing tape joints get quoted as a line item. We inspect before we clean, then repair what needs repairing, which not every company does.
- Existing IAQ equipment. If your system has Honeywell or Aprilaire components, we know how to work around them without voiding your setup. That familiarity is included in the estimate, not added to it.
How to Save on Air Quality & Sanitizing
The biggest savings come from doing the work before the system gets bad. A cleaning on a moderately dusty system costs far less than a containment job, and catching a pulled-apart flex connection early keeps it from dumping attic air into your living space for a year.
- Combine services in one visit. Duct cleaning and dryer vent cleaning together share setup time, so the second service costs less than a standalone trip.
- Get the inspection first. We tell you what we find before we quote. If your ducts are in decent shape, that’s a real answer and it saves you money.
- Fix small problems now. A $200 duct repair beats a much larger cleaning later after a disconnected run has been dumping debris into the system.
- Ask about protecting the finish. Our Guardsman-brand protection products seal and protect surfaces after cleaning, which is cheaper than dealing with damage down the road.
- Don’t chase the cheapest coupon. A lowball price usually buys a quick blow-through that puts debris back into your air. You end up paying twice.

FAQs – Air Quality & Sanitizing Cost
How much does air duct cleaning and sanitizing cost in Gilroy?
Expect roughly $350 to $750 for most homes, with sanitizing adding $80 to $200. Larger two-story homes and heavily contaminated systems land higher, up to about $1,500 when containment is needed. Call (833) 589-9833 for a free estimate that reflects your actual system.
Is it cheaper to clean the ducts or replace them?
Cleaning is almost always cheaper, and replacement is rarely necessary unless the ductwork is failing structurally. Cleaning runs $350 to $750, while selective duct repair of bad sections typically runs $200 to $600 per area, still far below a full replacement. We inspect first and tell you plainly which applies to your home.
How much does dryer vent cleaning cost in Gilroy?
Most dryer vent cleanings run $150 to $300 depending on vent length and routing. We clear the line, measure airflow, and confirm the vent exhausts properly, because blockage is a genuine fire hazard rather than a minor annoyance. Call (833) 589-9833 to schedule.
Can you come today?
Same-day service is often possible, depending on the day’s schedule. We answer 24/7, and fast dispatch from 7am to 7pm, Sunday through Friday; a call outside dispatch hours is booked into the next opening. Call (833) 589-9833 and we’ll find the earliest slot.
Why do some duct cleaning quotes come in so much lower?
Cheap quotes usually reflect consumer-grade blowers and brushes rather than professional systems. We use Rotobrush contact cleaning, where the brush physically scrubs the duct wall, with a Nikro HEPA vacuum running the entire time so loosened debris doesn’t re-enter your living space. That equipment costs more to run, and it’s why our $350 to $750 range is honest work rather than a fast pass.
What Our Equipment Means for Your Price
The estimate reflects the tools and the time. Rotobrush is the industry benchmark for contact-based duct cleaning, and the Nikro HEPA vacuum ensures what we loosen gets captured, not recirculated. For heavy jobs, Abatement Technologies air filtration units let us hold negative pressure so contamination stays contained. And because our scope runs from cleaning to dryer vents to air duct repair, one visit handles diagnosis through resolution. Duct Cleaning Gilroy has been doing this work since 2011, and we’ve built our reputation on showing customers exactly what we found.

What Our Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Tara Parker"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
- Lucia Ramirez"Job was done well and the house smells better. There was some dust knocked loose around a couple of the registers that I had to wipe down afterward."
