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.

AfterAir Duct Cleaning Company in St. Helena, CA
Most St. Helena homes run between $320 and $640 for a full air duct cleaning, depending on system size and how much wildfire ash and harvest dust has settled inside. This page exists to answer the St. Helena-specific questions we hear most: what pricing looks like here, why this valley loads ductwork so fast, and which neighborhoods we serve. If you’re ready to schedule or want a written quote before any work begins, call (469) 972-3151.
Why St. Helena Homes Are Different
St. Helena sits in the narrowest part of the Napa Valley, tucked directly beneath the Mayacamas to the west and the Vaca range to the east. The 2020 Glass Fire burned into the hills immediately above town, and the fine ash that settled into homes that fall is still being pulled out of ductwork today. Then comes harvest. From September through November, tractor and truck traffic on Highway 29 and Silverado Trail kicks up sustained agricultural dust that finds its way into return registers and settles along the duct walls.
The housing stock adds a second variable. A large share of St. Helena’s residential core is late-Victorian and early-20th-century construction along streets like Oak and Adams, with Craftsman bungalows and some mid-century infill scattered throughout. Older duct systems in these homes are frequently retrofitted into original plaster walls, sometimes partially unlined, which creates ledges and corners where debris accumulates far faster than in modern trunk-and-branch systems. Add the Napa Valley’s thermal inversion effect, which traps smoke and pollen close to the valley floor during late summer, and you get a town where ducts load up quicker than almost anywhere else in the Bay Area.
Our Main St. Helena Services
Two services account for the majority of the calls we take from St. Helena homeowners, and each has its own dedicated page with full pricing and job detail.
Air Duct Cleaning in St. Helena
Wildfire ash and harvest dust do not behave like ordinary household dust. They’re finer, stickier, and settle deeper into the duct walls, especially in older St. Helena homes where the returns pull from original floor grates. Our Air Duct Cleaning in St. Helena service uses Rotobrush agitation to dislodge debris at the duct wall and Nikro negative-pressure extraction to pull it out of the home, with HEPA filtration keeping every loosened particle out of your living space. The written price you get before we start is the price you pay when we finish.
Dryer Vent Cleaning in St. Helena
Dryer vents in St. Helena clog faster than homeowners expect, partly because the valley’s dry-season air suspends fine dust, and partly because many older homes here run long vent runs through original walls. We use a lint trap bypass so the trap itself gets cleaned as part of the job, not skipped as a shortcut. See Dryer Vent Cleaning in St. Helena for what the work involves and how to know when it’s overdue. A clogged vent is a fire risk, and the solution is simpler than most people think.

Pricing for Air Duct Cleaning Company in St. Helena, CA
| Service | Typical range in St. Helena |
|---|---|
| Up to 10 vents | $320-$440 |
| 11 to 15 vents | $440-$560 |
| 16 to 25 vents | $540-$720 |
| 26 vents and up | $680-$900+ |
| Single return replacement | $120-$220 |
| Two returns replaced | $220-$420 |

| Dryer vent cleaning | $90-$160 |
| Dryer vent + air ducts (combo) | $390-$680 |
What pushes a St. Helena job toward the higher end of these ranges is usually access: older Victorians and Craftsman homes with original plaster walls sometimes require an access panel to reach a section of ductwork that has never been opened. That is a fixed, written line item, not a surprise at the door. Every job gets a written price before a single vent is touched, and that number stays the same when we finish.

FAQs About Air Duct Cleaning Company in St. Helena
Most jobs in St. Helena are scheduled within five to seven business days. Harvest season and the first cold snap in November bring a local spike in calls, so the post-harvest window can fill a week or two out. Call (469) 972-3151 and we’ll give you an exact date, not a “we’ll see” answer.
No. Air duct cleaning and dryer vent cleaning are maintenance services, not construction, so no city permits or HOA approvals are involved. The only time permitting enters the picture is if a structural change like a new vent run is required, which we’ll flag before any work begins.
We provide before-and-after photos of your own ducts as part of every St. Helena job, taken with a digital inspection camera during the walkthrough. You see the exact duct interiors we cleaned, not stock footage. That documentation is part of the written 365-Day Done Right Promise, and held on file if anything ever comes up.

What St. Helena Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
