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.
Air Duct Cleaning Company in Napa, CA
Air duct cleaning in Napa runs $350 – $650 for most single-family homes, with whole-system jobs for larger vineyard estates reaching $800 – $1,200. We’re Hollis Air Duct Cleaning, and we’ve learned that Napa jobs aren’t like standard dust-removal calls. The Mayacamas and Vaca ranges funnel wildfire smoke straight into HVAC systems, and the valley’s mix of 1920s bungalows, mid-century tract homes, and modern wine-country estates means every duct layout needs its own assessment. Call (361) 326-5060 for a free written estimate.
Why Napa Homes Are Different
Napa’s housing stock splits three ways, and each type carries its own duct problems. Downtown and the West End still hold pre-1940 bungalows and Victorians with original gravity furnaces or retrofitted forced-air systems, often with galvanized metal ductwork that’s corroded or poorly sealed at the joints. North Napa’s 1960s – 70s tract homes in neighborhoods like Bel Aire and Silverado neighborhoods run flex duct that’s brittle after fifty summers, and the original installations rarely met today’s airflow standards. Then there are the newer vineyard estates along Highway 29 and up Atlas Peak Road, with multi-zone systems serving 4,000-square-foot homes plus guest houses and barrel rooms, where one dirty zone can contaminate the whole building.
The climate makes it worse. Dry, hot summers pull wildfire smoke and ash through return vents, and that smoke carries volatile phenols, the same compounds that ruin wine grapes. After the 2020 Glass Fire, we cleaned ducts in Coombsville and Atlas Peak where homeowners could still smell smoke months later. Winter brings the opposite problem: damp, foggy mornings that let mold colonize ductwork in older homes with crawl-space returns or poor exterior sealing. In Napa, duct cleaning is seasonal maintenance and post-disaster remediation, sometimes in the same year.
Our Main Napa Services
Most calls we get from Napa homeowners fall into three categories: whole-system duct cleaning, dryer vent cleaning for fire prevention, and duct sealing to stop conditioned air from leaking into attics and crawl spaces.
Air Duct Cleaning in Napa
We clean supply and return ducts with a rotary brush system from Rotobrush that loosens debris, paired with a Nikro negative-air machine that pulls it out under controlled suction. In Napa, we pay special attention to smoke residue in return plenums after fire season, and we check flex duct in older homes for tears where rodents have gotten in. Every job gets a written price before we start and a 365-Day Done Right Promise in writing. Air Duct Cleaning in Napa

Dryer Vent Cleaning in Napa
Lint buildup in dryer vents is a leading cause of house fires, and Napa’s dry summers make the risk worse. We run a rotary brush through the full vent line to the exterior cap, then test airflow with an anemometer to confirm the dryer’s working at manufacturer spec. For homes with long vent runs through crawl spaces or second-floor laundry rooms, we check for sagging flex pipe where lint collects. Dryer Vent Cleaning in Napa

Duct Sealing in Napa
Leaky ducts waste 20 – 30% of conditioned air in most homes, and Napa’s older stock is worse. We seal accessible joints with mastic and apply aerosol sealant where ductwork runs through unconditioned attics. In wine-country estates with zoned systems, we test each zone independently to find leaks that throw off temperature balance between the main house and guest quarters. Duct Sealing in Napa

FAQs About Air Duct Cleaning Company in Napa
No permit is required for standard duct cleaning or dryer vent cleaning in Napa. Duct sealing that involves modifying duct routing or capacity may need a permit from the City of Napa Building Division; we’ll flag that during your estimate and handle the paperwork if it’s needed. Call (361) 326-5060 to discuss your specific job.
We expand capacity during and after fire season, but demand peaks fast. We recommend calling as soon as you smell smoke in your vents or notice ash around registers, even if the fire seems distant. We keep a standby list and will fit you in as soon as a crew is available.
Some Napa Valley estates and gated communities have HOA rules about contractor hours, vehicle types, or noise. We check HOA requirements when you book and schedule inside approved windows. Our trucks are marked and our technicians wear uniforms, which most HOAs require for identification.
