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.

AfterFast, Reliable Air Duct Cleaning Across Berkeley
Most Berkeley homeowners pay between $380 and $720 for a full residential air duct cleaning, with camera inspection adding $120 to $195. We dispatch from our San Francisco Bay Area office and schedule Berkeley appointments with a two-hour arrival window you’ll actually get.
We’ve worked the crawlspaces under Elmwood bungalows and the hillside systems above Claremont Canyon. Berkeley’s not generic suburbia. The marine layer that keeps your summers mild also keeps humidity climbing through vented crawlspaces where decades-old ductwork sits. That changes what “clean ducts” actually means here. Our Air Duct Cleaning team uses Rotobrush agitation, Nikro negative-air extraction, and Abatement Technologies HEPA containment because surface vacuuming doesn’t touch what’s growing inside fibrous liner in a damp Berkeley crawlspace. Call (469) 972-3151 and we’ll give you a written price before any work starts.
Why Kestrel Air Duct Cleaning Is Berkeley’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Berkeley by showing up in the window we promised and putting the guarantee in writing. The Kingswell Way says it plainly: say the price, arrive on time, leave the site cleaner, and come back free if it fails. Dale Whitmore has overseen operations since 2004, and that same written standard applies whether we’re working a Northbrae brown-shingle or a 1990s rebuild in the Berkeley Hills.
Berkeley customers call us back because we answer the phone with a live person, 24/7. No automated queue. No callback tomorrow. When the 2020 fire season pushed AQI past 200 for days straight, we fielded calls from homeowners who’d run their HVAC on recirculate and wanted to know what had settled in their ducts. We told them the truth: negative-pressure cleaning with HEPA filtration removes settled particulate; a scented fog does not.
Our technicians are background-checked, uniformed, and trained on the equipment that matters for this market. Rotobrush rotary systems dislodge debris at the duct wall. Nikro negative-pressure units pull it out. Abatement Technologies HEPA filtration keeps what we loosen from circulating through your living space. We don’t bring shop vacs to a mold job.
Ductwork Cleaning in Berkeley
Ductwork Cleaning in Berkeley addresses a specific set of problems you won’t find inland. The persistent marine layer drives crawlspace humidity well above East Bay norms for much of the year. That moisture colonizes fibrous interior liners and flex duct in ways that simply don’t happen in drier cities like Concord or Livermore. We see it constantly in pre-WWII Craftsman bungalows in the Elmwood, Northbrae, and Claremont districts, where forced-air systems were retrofitted decades after original construction and the duct runs now sit in vented, moisture-prone crawlspaces.
A typical residential ductwork cleaning in Berkeley runs $380-$620 for a single-system home, $520-$720 for larger homes with dual zones or extensive crawlspace runs. Commercial systems start around $890 depending on square footage and access.
Source Removal vs. Surface Treatment
Real ductwork cleaning means agitating debris loose at the duct wall, then extracting it under negative pressure with HEPA filtration. We don’t fog “sanitiser” into your system and call it done. In Berkeley’s humid crawlspaces, that approach masks mold odor without removing the colonized liner or rodent debris. We remove the source.
Post-Fire Rebuild Systems
Berkeley Hills homes rebuilt after the 1991 Oakland-Berkeley Hills firestorm have ductwork dating to 1992-1996. Those systems are now 28-33 years old. The original flex duct and liner materials are breaking down. We clean what we can and flag what needs replacement, documented with camera footage you can see.
Air Duct Inspection in Berkeley
Air Duct Inspection in Berkeley should happen before any cleaning quote is finalized, especially in homes with crawlspace duct runs or wildfire smoke exposure history. We run a high-resolution camera through your supply and return lines, documenting what we find. The inspection typically costs $120-$195 in Berkeley, and we apply that fee toward your cleaning if you proceed.
Inspection matters here because Berkeley’s housing stock hides problems that don’t show at the register. A system can move air normally while harboring mold bloom or rodent debris in a crawlspace section the homeowner never sees. Camera inspection removes that uncertainty.
What We Document
We record liner condition, joint separation, rodent evidence, and moisture staining. You see the footage. We explain what needs cleaning, what needs sealing, and what may need replacement. No surprises after we’ve started.
When to Schedule
Schedule inspection if your home is 25+ years old, if you’ve noticed musty odors when the system runs, if allergy symptoms persist year-round, or if you ran recirculating HVAC during any recent wildfire smoke event. For Berkeley Hills rebuilds from the early 1990s, inspection is overdue.
Trusted Brands We Service in Berkeley
We clean ductwork connected to every major HVAC manufacturer, and we stock Honeywell and Aprilaire filtration products for Berkeley homeowners who want to maintain cleaner air between service visits. Honeywell media air cleaners and Aprilaire whole-house purifiers integrate with most forced-air systems common in Berkeley’s retrofitted bungalows and hillside rebuilds. We also carry Guardsman UV treatment options where biological contamination is recurrent. Parts are available through our San Francisco Bay Area supply chain, so replacement filters or upgraded media don’t require a two-week order delay. If your system needs a specific component during cleaning, we can usually source it without rescheduling.
Common Air Duct Cleaning Problems We See in Berkeley Homes
- Mold colonization in crawlspace flex duct. Berkeley’s marine layer keeps humidity elevated year-round in vented crawlspaces. Fibrous interior liners absorb that moisture and grow mold that circulates spores every time the blower cycles. Homeowners often mistake the symptoms for seasonal allergies.
- Rodent harborage in retrofitted sheet-metal runs. 1950s-60s retrofit duct in Elmwood and Northbrae Craftsman homes wasn’t sealed to modern standards. Gaps at joints become rodent highways. We find nesting material, droppings, and chewed liner that homeowners never knew existed.
- Wildfire PM2.5 accumulation in 1990s hillside systems. Berkeley Hills homes rebuilt after the 1991 firestorm have ductwork that pulled in fine particulate during the 2018 Camp Fire, 2020 fire season, and other high-AQI events. That particulate settles in ductwork and recirculates during subsequent use.
- Degraded liner in post-fire rebuilds reaching end of service life. The original ductwork installed in 1992-1996 Berkeley Hills rebuilds is now past the 25-year mark where liner breakdown accelerates. Cleaning helps, but inspection often reveals sections where replacement is the honest recommendation.
Pricing for Air Duct Cleaning in Berkeley, CA
Most Berkeley homes fall into these ranges:
- Single-system residential ductwork cleaning: $380-$620
- Dual-zone or large home with extensive crawlspace runs: $520-$720
- Camera inspection: $120-$195 (credited toward cleaning)
- Commercial duct cleaning: $890 and up, based on square footage and access
What moves you within these ranges? System size, number of supply and return vents, crawlspace accessibility, and whether we find conditions that need additional attention. We don’t quote per-vent pricing that balloons at the door. We inspect, we write one flat price for the complete system, and you hold that paper before we touch a single vent. The price doesn’t change because we “found something unexpected.” That’s the Kingswell Guarantee, and it’s been our standard since 2004.

FAQs About Air Duct Cleaning in Berkeley
Berkeley’s persistent marine layer keeps crawlspace humidity elevated for most of the year, well above the drier conditions in Walnut Creek, Concord, or Livermore. That moisture colonizes fibrous duct liner and flex duct in vented crawlspaces, creating biological growth that inland cities simply don’t see at the same rate. If you’re in an Elmwood or Northbrae Craftsman with retrofitted ductwork, this is likely your primary contamination source, not dust. Call (469) 972-3151 and we’ll camera-inspect to confirm.
No. Fogging masks odor and may kill surface mold, but it does not remove colonized liner, rodent debris, or the moisture source that allows regrowth. In Berkeley’s humid crawlspaces, that regrowth happens fast. Source removal with brush agitation and negative-air extraction is the only approach that actually takes the contamination out of your home. We don’t sell fogging as a substitute for cleaning.
Yes. Ductwork in those rebuilds dates to 1992-1996, making it 28-33 years old. Original flex duct and liner materials break down, accumulate debris, and may have pulled in wildfire particulate during subsequent fire seasons. Camera inspection will show you the actual condition. Cleaning is often appropriate; replacement of degraded sections is sometimes the honest recommendation.
Fine PM2.5 particulate from wildfire smoke events, including the 2018 Camp Fire and extended 2020 fire season, settles in ductwork and on system components. When you later run your HVAC, that particulate recirculates. Negative-pressure cleaning with HEPA filtration removes settled particulate. If you ran recirculate mode during high-AQI days and haven’t had your system cleaned since, that contamination is likely still present.
Musty or earthy odors when the blower runs, persistent allergy or respiratory symptoms that don’t track with pollen seasons, visible dust plumes at registers, or uneven airflow between rooms. In Berkeley specifically, year-round symptoms in a home with crawlspace ductwork strongly suggest mold or rodent contamination rather than typical dust accumulation. Camera inspection is the definitive check. Call (469) 972-3151 for a free estimate.
