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 Strawberry
Air duct cleaning in Strawberry typically runs $380 – $680 for a full residential system, and most jobs are scheduled within a few days of your call. We’re familiar with the mid-century ranches along Strawberry Drive and the split-levels tucked into the hills above Tiburon Boulevard, where original ductwork from the 1960s and 70s still moves air through uninsulated crawlspaces and exterior wall chases. Our crews serve Strawberry from our San Francisco Bay Area dispatch office, and we know the local building patterns well enough to bring the right equipment for foil-tape joints that have dried out from decades of marine-layer humidity. If you’re smelling musty, salty air when the furnace kicks on, or you’re sneezing through the first redwood pollen surge of late summer, call us at (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Strawberry’s Preferred Air Duct Cleaning Company
We’ve worked in Strawberry long enough to know that duct cleaning here isn’t just about dust removal. It’s about stopping the crawlspace from functioning as your home’s unintended air intake. The unincorporated neighborhoods on the Tiburon Peninsula sit close enough to the bay and Pacific that salt-laden onshore air moves freely through open underfloor spaces, and that air carries directly into living rooms through unlined wall-cavity returns that were standard construction in the 1950s through 1970s.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. Every job gets a written price before any work starts, backed by our 365-Day Done Right Promise. If something fails within a year, we return and make it right at no charge, including a free second visit. That’s not a slogan; it’s written on every invoice. Our phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting through voicemail loops when you have a question about scheduling or what happened during your last service.
We don’t compete on the lowest teaser price. We compete on showing up, pricing it honestly, and leaving the site clean. That’s The Garrison Standard, and it’s how we operate in Strawberry and every community we serve.
Commercial Air Duct Cleaning in Strawberry
Commercial Air Duct Cleaning in Strawberry addresses the same marine-layer challenges as residential work, but at scale for office buildings, retail spaces, and small commercial properties along the Tiburon Boulevard corridor and near the Strawberry Village shopping area. These systems accumulate salt aerosol, redwood pollen, and mold spores that enter through rooftop units and crawlspace connections, then redistribute through occupied spaces. A typical commercial duct cleaning in Strawberry runs $800 – $2,400 depending on system size and accessibility. We schedule these jobs to minimize disruption to your business hours.
System Assessment and Access Planning
Commercial ductwork in Strawberry’s low-rise buildings often runs through shared crawlspaces or above dropped ceilings with limited access points. We inspect with video cameras first, then plan our negative-air or rotary brush approach based on what we find, not on a one-size-fits-all protocol.
Post-Cleaning Verification
After cleaning, we run a final video inspection so you can see the difference in your own ducts. We provide written documentation of what was cleaned, what condition we found, and any recommendations for sealing or filtration upgrades.
Air Duct Cleaning Services in Strawberry
Air Duct Cleaning Services in Strawberry cover the full range of residential systems found in this unincorporated peninsula community, from original sheet-metal trunk lines in 1950s ranches to flex-duct additions in later split-levels. A typical full residential cleaning here runs $380 – $680, with supply-only or return-only cleanings at the lower end of that range. Most Strawberry homeowners schedule this work in late September when the first furnace cycle reveals months of accumulated crawlspace odor, or in spring after peak redwood pollen season.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; returns pull it back. In Strawberry homes with unlined wall-cavity returns, the return side is often the dirtiest because it’s actively drawing air through gaps in the building envelope. We clean both sides with equal attention, using rotary brush systems or negative-air machines depending on duct material and condition.

Video Inspection and System Documentation
We record before-and-after footage inside your ductwork. You’ll see exactly what was removed and what condition your system is in. This matters particularly in Strawberry, where aging foil-tape joints can fail during cleaning and need immediate attention to prevent pressure loss.

Trusted Brands We Service in Strawberry
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation in older sheet-metal ducts, Nikro negative-air machines for thorough debris extraction, and filtration products from Aprilaire and Abatement Technologies. We stock parts and filters compatible with these brands so Strawberry customers aren’t waiting on special orders. When we recommend a filtration upgrade after cleaning your system, we’re talking about hardware we can install on the same visit, not a referral to another vendor. The Guardsman line of access panels and sealing products lets us close up wall-cavity returns properly when the original construction left them open to the crawlspace.
Common Air Duct Cleaning Problems We See in Strawberry Homes
- Unlined wall-cavity returns acting as crawlspace intakes. Many Strawberry homes were built with return air pathways framed directly into exterior walls, open to the crawlspace below. We regularly find these pulling in dust, salt air, and occasional moisture, which means the “return” is really just recycling whatever is under your floor.
- Dried foil-tape joints failing during service. On the east side of Strawberry along Tiburon Boulevard, the original 1960s ductwork often has foil tape that has hardened from decades of marine-layer humidity. When our brush or negative-air equipment engages, these tapes can unseal and cause audible pressure changes in the living room. We carry mastic and proper sealing materials to repair this on the spot.
- Late-season musty odor on first furnace cycle. Warm, dry late summers and fall allow mold spores and dust to accumulate in duct runs exposed to crawlspaces. When the furnace fires up in September or October, that first blast carries the smell of months of stagnant, salty attic air directly into bedrooms and living spaces.
- Redwood and oak pollen accumulation in flex-duct additions. Homes that added flex duct in later decades often have sagging runs in crawlspaces where pollen collects in low spots. The first heating cycle of fall sends this accumulated material airborne, triggering allergic responses that homeowners mistake for seasonal colds.
Pricing for Air Duct Cleaning in Strawberry, CA
A typical full residential air duct cleaning in Strawberry runs $380 – $680 for a complete supply-and-return system. Supply-only or return-only cleanings generally fall in the $280 – $420 range. Commercial systems start around $800 and can reach $2,400 for larger properties with multiple zones or difficult access. What moves you within these ranges: the number of vents and returns, whether your system includes unlined wall cavities that need special attention, the condition of original sealing materials, and whether we find failed joints that need repair during the cleaning.
We give you one flat price per system, agreed in writing before any work starts. No per-vent add-ons. No surprise charges when the technician arrives.

FAQs About Air Duct Cleaning in Strawberry
We typically schedule residential duct cleaning in Strawberry within 3 – 5 business days, and sometimes sooner depending on season. Late September through October is our busiest period as homeowners turn on furnaces for the first time and smell crawlspace air, so calling in late summer secures your preferred slot. Call (361) 326-5060 to check current availability.
Yes, we service the full unincorporated area, from the Tiburon Boulevard corridor east to the hillside homes above Strawberry Drive and the lower properties near the water. The hillside access doesn’t change our pricing, though homes with crawlspace access limited by grade may take slightly longer to set up equipment.
We don’t advertise emergency dispatch for duct cleaning because it’s a scheduled maintenance service, not an urgent repair. However, our phones are answered by a live person 24/7, and if you’re experiencing severe respiratory issues or a known contamination event, we’ll prioritize your scheduling and advise on immediate steps like system shutdown until we arrive.
Strawberry pricing is consistent with our Bay Area rates and comparable to what we charge in Pollock Pines or Placerville. The specific factors that raise or lower your quote are home-specific, not location-specific: vent count, system accessibility, and whether we find failing seals or unlined returns that need additional work. We don’t charge a premium for peninsula locations.
If any part of our cleaning fails within one year, we return and make it right at no charge, including a free second visit. This covers re-contamination due to incomplete cleaning, equipment failure during the service that leaves debris behind, and any seal repair we performed that doesn’t hold. The promise is written on every invoice, not implied. Call (361) 326-5060 if you have concerns within the year.
