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.
Fast, Reliable Air Duct Cleaning Across Napa
Air duct cleaning in Napa typically runs $350 – $850 for a full residential system, with most jobs completed in a single visit. Our crews serve Napa from our San Francisco Bay Area dispatch office, and we schedule appointments with a written arrival window, not a vague “sometime Tuesday.”
We’ve worked in Napa homes long enough to know the real problems aren’t just dust. After the 2020 Glass Fire, we started finding ash and smoke residue deep in return ducts from Browns Valley to Silverado Country Club. Older homes downtown still run on original galvanized ductwork from the 1920s and 30s, often retrofitted badly. Newer vineyard estates have multi-zone systems that need rotary brush and negative-air cleaning, not a shop-vac and a prayer. When you call (361) 326-5060, a live person answers, and we give you a written price before any work starts. That’s The Garrison Standard, and it’s how we operate in every Napa home we enter.
Why Hollis Air Duct Cleaning Is Napa’s Preferred Air Duct Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In Napa, that means something specific: we understand post-wildfire remediation, we carry the right equipment for historic ductwork, and we don’t treat a Coombsville estate the same as a 1970s tract home in north Napa.
Our technicians are background-checked and uniformed. You know who’s walking through your door before they arrive. Every job gets a written price before work begins, and every repair is covered by our 365-Day Done Right Promise. If the work fails within a year, we come back and make it right at no charge, including a free second visit.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. No waiting until Monday to schedule.
We use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, plus filtration products from Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use on winery HVAC systems, and we bring them to your home.
Vent Cleaning in Napa
Vent cleaning in Napa starts at $180 – $280 for a standard residential system, though homes with heavy wildfire ash accumulation or multiple returns may run higher. The job involves removing each supply and return register, agitating built-up debris with a rotary brush system, and extracting it under negative pressure with HEPA filtration so nothing recirculates into your living space.
Most Napa homeowners need vent cleaning every three to five years, but after a major smoke event like the Glass Fire, we’ve recommended sooner. The dry, hot summers here pull fine particulate deep into the system, and winter dampness in older homes can turn that residue into a mold substrate.
Smoke and Ash Removal
Wildfire smoke carries volatile phenols, the same compounds that taint wine grapes. These don’t just sit in your ducts, they adsorb into the metal and flex surfaces. Our Air Duct Cleaning crews use source-removal techniques with sealed HEPA vacuums, not compressed air that blows contamination through your home.
Register and Grille Deep Clean
Supply registers in kitchens and bathrooms collect the most debris. We remove each one, clean the boot and surrounding drywall, and inspect for disconnected ductwork behind the wall. In a 1920s bungalow near downtown Napa, our tech pulled return registers and found original 4-inch galvanized runs packed with ash from the 2020 Glass Fire and a crushed flex duct behind the air handler; after source removal under negative pressure with HEPA filtration and camera inspection, we sealed the disconnected joint and restored balanced airflow to the supply and return ducts.
Air Duct Repair in Napa
Air Duct Repair in Napa typically costs $200 – $650 depending on accessibility and material, with most repairs identified during cleaning when our camera finds the damage you can’t see from the register. The job isn’t just patching holes. It’s reconnecting runs that have separated, replacing crushed flex duct, and sealing joints with mastic so your system doesn’t pull attic air or crawlspace moisture into your living space.
Napa’s housing stock creates specific repair needs. Pre-1940 bungalows and Victorians downtown often have original galvanized ductwork that’s corroded, disconnected, or was retrofitted with flex duct in the 1980s by someone who didn’t secure the connections. North Napa tract homes from the 1960s and 70s have aging flex duct that’s brittle, collapsed, or pulled loose by rodents. Modern vineyard estates have multi-zone systems with damper issues and sealed duct runs that require specialized access.
Galvanized Ductwork Restoration
Original metal duct in downtown Napa homes can last a century if maintained, but joints loosen and seams leak. We inspect with a borescope camera, then seal with mastic or replace sections as needed. This is precision work. You can’t assess it from the vent cover.
Flex Duct Replacement
Flex duct has a 25 – 30 year lifespan. In north Napa neighborhoods built in the 60s and 70s, we’re regularly finding material that’s brittle, torn, or crushed. We replace with new insulated flex, properly supported and sealed, so airflow reaches every room.
Trusted Brands We Service in Napa
We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman for Napa customers, which means faster turnaround on repairs and replacements. Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for source removal, and Abatement Technologies HEPA filtration for containment. These aren’t hardware-store tools. They’re the same systems we use on commercial winery HVAC jobs in the Carneros AVA, and we bring that standard to your home. When we recommend a filtration upgrade or a sealing product, we can install it same visit because we carry the inventory.
Common Air Duct Cleaning Problems We See in Napa Homes
- Wildfire smoke residue in returns. After the 2020 Glass Fire, homes near the Mayacamas and Vaca ranges pulled ash and volatile phenols into return ducts. Standard dust removal doesn’t address this. Source removal with negative pressure and HEPA filtration is required, followed by sealing to prevent recontamination.
- Disconnected original ductwork in pre-1940 homes. Downtown Napa bungalows and Victorians often have galvanized runs that have separated at joints or were poorly retrofitted with flex duct. Contractors who skip camera inspection miss this entirely, leaving homeowners with airflow to some rooms and none to others.
- Crushed flex duct in 1960s-70s tract homes. North Napa subdivisions have aging flex duct that’s been compressed by storage in attics, damaged by pests, or simply deteriorated. Some crews “clean” around it, leaving smoke ash recirculating through the blower motor.
- Unsealed ductwork pulling crawlspace and attic air. Napa’s winter dampness promotes mold in unconditioned spaces. Leaky return ducts pull that air into your system. We find this in older homes with original construction and in newer homes where duct sealing was skipped to save money.
Pricing for Air Duct Cleaning in Napa, CA
A typical full residential duct cleaning in Napa runs $350 – $850 for a single system. Vent cleaning alone starts at $180 – $280. Air duct repair identified during cleaning typically adds $200 – $650 depending on material and access. Commercial systems and multi-zone vineyard estates require custom quotes based on square footage and HVAC complexity.
What moves the price: system size, number of returns, accessibility (crawlspace vs. attic), contamination level (routine dust vs. post-wildfire ash), and whether we find disconnected or damaged ductwork that needs repair. We give you one flat price per system, agreed in writing before we start. No per-vent pricing. No add-ons at the door. We show you before-and-after photos of your own ducts so you know the work was done.

FAQs About Air Duct Cleaning in Napa
Yes, but only with source-removal techniques using negative-air machines and HEPA filtration, followed by sealing. Blowing compressed air through ducts or using a basic rotary brush without containment will redistribute smoke particles and volatile phenols throughout your home. We treat post-wildfire jobs as remediation, not routine cleaning. Call (361) 326-5060 for an exact quote – estimates are free.
Pre-1940 bungalows and Victorians in downtown Napa often have original galvanized ductwork with separated joints, corroded sections, or bad retrofits hidden behind walls. You can’t see this from the register. Our borescope camera finds crushed runs, disconnected boots, and gaps that explain why some rooms never get airflow. Skipping inspection means cleaning a broken system. Call (361) 326-5060 for an exact quote – estimates are free.
Winery barrel rooms and tasting areas use the same HVAC principles as homes, just at larger scale. Smoke infiltration risks tainting wine and creating persistent odor that affects visitor experience. We clean these systems with commercial-grade negative-air equipment and can recommend filtration upgrades from Honeywell or Aprilaire suited to high-particulate environments. Call (361) 326-5060 for an exact quote – estimates are free.
Yes. The flex duct installed in these homes has exceeded its 25 – 30 year lifespan. It’s brittle, often crushed by attic storage or rodent damage, and the original connections have loosened. We’ve found crews who “cleaned” these systems without repairing the underlying damage, leaving homeowners with recirculating ash and unbalanced airflow. We replace deteriorated flex duct and seal joints properly. Call (361) 326-5060 for an exact quote – estimates are free.
No, it’s a separate service. Dryer vent cleaning addresses lint buildup in the exhaust line from your clothes dryer to the exterior wall or roof termination. It’s critical for fire safety, especially in Napa’s dry climate where lint is highly combustible, but it doesn’t involve your HVAC ductwork. We offer both services and can schedule them together. Call (361) 326-5060 for an exact quote – estimates are free.
