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 Alum Rock
Air duct cleaning in Alum Rock typically runs $380-$620 for a full residential system, with most jobs completed in a single morning. We’re the local team that shows up in the window we promised, puts the price in writing before touching a single vent, and backs the work with our 365-Day Done Right Promise. Call (469) 972-3151 for a free estimate.
We’ve been driving the hill streets off Alum Rock Avenue long enough to know the pattern. Your home’s duct system wasn’t built for the particulate load the Diablo foothills throw at it. Dry-season dust, late-summer brush-fire ash, and decades of accumulation in original 1950s-70s sheet-metal runs - we see it in every neighborhood from the flats near King Road up to the canyon-edge tracts below Alum Rock Park. Our crews dispatch from the San Francisco Bay Area office and carry Rotobrush rotary systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration built for exactly this kind of heavy-load cleaning.
Why Kestrel Air Duct Cleaning Is Alum Rock’s Preferred Air Duct Cleaning Company
Alum Rock homeowners call us back because we answer the phone with a live person, 24/7 - not a menu tree. That matters when you’re staring at a layer of gray dust on your return vent after a Diablo wind event and want to know what you’re dealing with.
Our reputation here is built on showing up. The Kingswell Way means we give you a written arrival window and honor it. We say the price before we start, leave the job site cleaner than we found it, and put our 365-Day Done Right Promise in writing on every invoice. If the work falls short within that year, we return and make it right at no charge. That’s not a courtesy we extend when we feel like it. It’s a standing commitment, documented every time.
We know the local housing stock. The post-WWII working-class subdivisions that define Alum Rock - the tracts off White Road, the canyon-side streets near Penitencia Creek, the original builds along Alum Rock Avenue itself - carry duct systems that were never designed to be opened for cleaning. We don’t pretend otherwise. When we find a crushed flex run or a disconnected joint under a 1962 ranch, we tell you exactly what it takes to reach it and seal it.
Commercial Air Duct Cleaning in Alum Rock
Commercial Air Duct Cleaning in Alum Rock covers the small retail spaces, medical offices, and multi-tenant buildings that line the commercial corridors along Alum Rock Avenue and White Road, where aging HVAC infrastructure serves foot traffic from surrounding residential neighborhoods. These systems run harder and longer than residential units, and they’re rarely on the same maintenance cycle as the equipment itself. A typical commercial duct cleaning in Alum Rock runs $890-$1,400 depending on system size and accessibility, with most jobs scheduled during off-hours to avoid disrupting business operations.
System Accessibility in Older Commercial Buildings
Many Alum Rock commercial properties were converted from 1960s-70s retail or light-industrial construction, meaning ductwork is often concealed above drop ceilings that were added decades after the original HVAC install. Our techs map the full supply and return network with video inspection before proposing any work, so you’re not paying for access we can’t complete.
Coordinated Scheduling for Active Businesses
We clean Alum Rock commercial systems early morning or evening, working around your operating hours. The written price holds regardless of when we perform the service, and we leave no debris or equipment behind that would greet your customers or staff the next day.
Air Duct Cleaning Services in Alum Rock
Air Duct Cleaning Services in Alum Rock address the specific load pattern that foothill geography creates: fine ash and dust that enters through leaky duct joints even when windows stay shut, then accumulates across decades in systems that were never built for access. A typical full residential cleaning in Alum Rock runs $380-$620, with supply-only or return-only cleanings at the lower end of that range and comprehensive system restorations - including video inspection, brush agitation, negative-air extraction, and sealing - toward the upper end.
What Brush Agitation and Negative-Air Extraction Actually Do
Rotobrush rotary systems spin a soft-bristled cable through the duct run, knocking debris loose from the walls where it’s adhered. Nikro negative-pressure units create suction at the far end of the system, pulling that loosened material out before it can resettle. Abatement Technologies HEPA filtration captures particles as small as 0.3 microns, which matters in Alum Rock because foothill dust and wildfire ash include fine particulates that pass straight through standard shop-vac filters.
Video Inspection Before and After
We run a camera through your full duct network before we quote and after we finish. You see what we found, where we found it, and what remains when we’re done. In Alum Rock’s older homes, this often reveals disconnected flex runs, crushed sections from decades of crawl-space traffic, or ash deposits in return plenums that the homeowner never knew existed.

Trusted Brands We Service in Alum Rock
We clean and restore duct systems connected to every major HVAC brand, and we stock filtration upgrades from Aprilaire, Guardsman, and Honeywell for Alum Rock homeowners who want to maintain cleaner air between professional cleanings. Aprilaire whole-home media air cleaners install directly into your existing return ductwork and capture particles down to MERV 13 standards - useful in Alum Rock’s ash-heavy environment. Guardsman electrostatic filters are washable and reusable, a practical choice for the multi-generational homes here where replacement schedules often get forgotten. We carry these products on our trucks, so there’s no waiting for a parts run when your system needs protection before the next Diablo wind season.
Common Air Duct Cleaning Problems We See in Alum Rock Homes
- Original sheet-metal returns loaded with foothill ash. The 1950s-70s tract homes off Alum Rock Avenue and White Road have galvanized steel return plenums that were never sealed at the joints. Negative pressure pulls canyon dust and wildfire smoke straight through those gaps, depositing gray-to-black layers even in homes where every window stayed shut during a fire.
- Disconnected or crushed flex runs under the house. First-generation flex duct in Alum Rock’s crawl spaces has been walked on, hung from nails that rusted through, or simply pulled loose at the collar connections. We find these with camera inspection, and cleaning alone won’t fix the airflow - reconnection and sealing are part of a complete job.
- Blower motors caked with 20+ years of accumulation. Multi-generational occupancy is common in Alum Rock, and duct systems routinely go decades without service. By the time someone calls, the air handler is coated with debris that restricts airflow and strains the motor. We clean the blower assembly as part of full-system service, not as an upsell.
- Re-loading within months of a previous “cleaning.” Some Alum Rock homeowners have paid for duct cleaning that skipped the sealing step. Leaky joints remain, and the next Diablo wind event pulls fresh ash straight back in. We seal accessible joints with mastic and metal tape as standard practice, not as an add-on.
Pricing for Air Duct Cleaning in Alum Rock, CA
Most full residential systems in Alum Rock run $380-$620. Supply-duct-only or return-duct-only cleanings typically fall at $280-$420. Commercial systems start at $890 and scale with square footage and access complexity. What moves you within these ranges: the number of vents, whether your system uses original sheet-metal or retrofitted flex duct, how long it’s been since the last cleaning, and whether we find disconnected runs or significant ash loading that requires extended brush contact time.
We don’t quote per-vent. We quote per system, in writing, before any work begins. That written price is the price you pay. No door-step revisions, no “we found something unexpected” add-ons. Call (469) 972-3151 and we’ll give you a free estimate based on your specific home and system.

FAQs About Air Duct Cleaning in Alum Rock
Alum Rock sits at the canyon mouth of the Diablo foothills, where topography funnels dry-season dust and wildfire smoke directly into residential air intakes. Flat-valley San Jose neighborhoods don’t see this concentration of fine particulate, so homes here accumulate debris faster and on a fire-driven cycle rather than a simple calendar schedule. Call (469) 972-3151 for a free estimate on your system’s current condition.
Older duct systems operate under negative pressure, which pulls outside air in through leaky joints and connections even when the house is sealed tight. In Alum Rock’s 1950s-70s tract homes, those joints were never designed to be airtight, so smoke-laden air enters through gaps in the return plenum and under-house connections. After a late-summer brush fire above Alum Rock Park, our tech pulled a return plenum cover in the 1950s tract section near Penitencia Creek and found gray ash layered across the original sheet-metal return - the homeowner had kept every window closed. Camera inspection showed two disconnected flex runs under the house feeding that plenum, and we sealed them before the next Diablo wind event.
We find original sheet-metal returns with decades of foothill dust and ash buildup, first-generation flex duct that has disconnected or crushed under the house, and blower motors caked with debris from 20-30 years of continuous operation. Camera inspection usually reveals at least one inaccessible section that was never built for cleaning access. We tell you exactly what we can reach, what it takes to reach what we can’t, and what the full restoration costs before we start.
Cleaning without sealing is temporary in Alum Rock. The same leaky joints that let ash in during Diablo wind events will re-load the system within months. We seal accessible joints with mastic and metal tape as part of our standard full-system service, and we document what we sealed on your invoice. If your system needs more extensive sealing than we can perform during a standard cleaning, we tell you that in the written quote and price it separately - never as a surprise at the door.
Yes. Our Nikro negative-pressure units maintain continuous suction during brush agitation, which is the NADCA-recommended method for containing loosened debris. Abatement Technologies HEPA filtration captures particles at the source, before they enter your living space. We don’t use shop vacs or compressed-air blowers that push debris into rooms. The equipment matters, and we name it because it matters.
