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 Mountain View
Air duct cleaning in Mountain View typically runs $350-$650 for a full residential system, with most jobs completed in a single morning or afternoon. We’re the local Air Duct Cleaning team that serves Mountain View from our San Francisco Bay Area dispatch office, and we’ve learned the hard way that this city’s housing stock doesn’t behave like newer construction elsewhere in Silicon Valley.
Mountain View’s neighborhoods tell a story the walls don’t. In Cuesta Park and Rex Manor, you’ll find pristine kitchen remodels hiding 1960s sheet-metal ductwork that hasn’t been opened since the Johnson administration. Our crews pull into driveways off Calderon Avenue and Middlefield Road every week, written estimate in hand before a single vent cover comes off. Call (469) 972-3151 and you’ll reach a live person, any time of day, who can book your free estimate and explain exactly what we’ll find in your particular Mountain View home.
Why Kestrel Air Duct Cleaning Is Mountain View’s Preferred Air Duct Cleaning Company
We’ve been working under the Kingswell Guarantee since 2004, and that same written standard applies to every Mountain View job we dispatch. Our technicians are background-checked, uniformed, and trained on Rotobrush rotary systems, Nikro negative-pressure units, and Abatement Technologies HEPA filtration, not the shop-vac specials that leave half the debris behind.
Mountain View homeowners call us back because we do something simple that other contractors skip: we put the price in writing before touching a single vent. No doorstep revisions, no “we found an extra problem” upsells. The Kingswell Way means we say the price, show up in the window we gave, leave the place cleaner than we found it, and put our 365-Day Done Right Promise in writing. If the work falls short within that year, we return and make it right at no charge. That’s not a courtesy; it’s a documented commitment on every invoice.
Our familiarity with Mountain View’s specific conditions saves time and money. We know which Rex Manor crawl spaces flood in January, which Cuesta Park ranch homes still run original fibrous duct liner, and how the Santa Clara Valley’s smoke-trapping geography loads PM2.5 into systems each fire season. That local knowledge means fewer surprises for us and honest expectations for you.
Commercial Air Duct Cleaning in Mountain View
Commercial Air Duct Cleaning in Mountain View covers office suites along San Antonio Road, retail spaces near Castro Street, and the smaller commercial flex buildings tucked between residential blocks. These systems typically run $800-$2,400 depending on square footage, access difficulty, and whether the building shares HVAC with neighboring tenants. Mountain View’s commercial stock includes a surprising amount of 1970s-era rooftop package units serving multiple suites, where one neglected tenant’s debris circulates through everyone’s vents.
Multi-Tenant System Isolation
Shared commercial HVAC in Mountain View’s older office parks requires careful zone isolation before cleaning begins. We seal each branch duct independently so debris from one suite doesn’t migrate into another during negative-air extraction, which is the process of pulling contaminants out under controlled suction.
Post-Construction Cleanup
Mountain View’s constant renovation cycle, especially near the downtown transit corridor, leaves fine construction dust in commercial ducts that standard janitorial can’t reach. We use brush agitation, which means mechanically dislodging debris from duct walls, followed by HEPA-filtered extraction so that dust doesn’t resettle in your workspace.
Air Duct Cleaning Services in Mountain View
Air Duct Cleaning Services in Mountain View address a specific local reality: decades of accumulated debris in systems that were never designed for today’s air quality demands. A typical full residential cleaning runs $350-$650, with supply-only or return-only cleans at the lower end and complete system restoration including sealing work toward the higher end. Mountain View’s 1950s-1960s ranch homes often need more than just debris removal; they need the disconnected runs, crushed flex sections, and failed tape joints that we discover during cleaning.
Camera Inspection and Documentation
We run a video scope through your ductwork before and after cleaning so you see what we see. In Mountain View’s original sheet-metal systems, we regularly find rodent debris predating the last crawl-space exclusion job, or fibrous liner that’s begun to delaminate and circulate into living spaces.
System Sealing and Restoration
Cleaning reveals the real problems: disconnected ducts blowing conditioned air into crawl spaces, crushed runs from that 1987 kitchen remodel, or failed tape at every joint. We quote sealing and repair separately, with the same written-price guarantee, because sometimes the cleaning is just the diagnostic.

Trusted Brands We Service in Mountain View
Our Mountain View crews carry Aprilaire media filters and Guardsman filtration products for homeowners who want to maintain clean air between service visits. For the cleaning itself, we deploy Abatement Technologies HEPA filtration to capture loosened particles during the job, not redistribute them. We don’t upsell equipment you don’t need, but we do stock replacement filtration products locally so Mountain View customers aren’t waiting on shipping. If your system would benefit from upgraded filtration after a thorough cleaning, we’ll show you the specific Aprilaire or Guardsman model that fits your return plenum and explain why it matters for the particular particulate load your Mountain View home faces each fire season.
Common Air Duct Cleaning Problems We See in Mountain View Homes
- Original fibrous duct liner breaking down. In Cuesta Park and Rex Manor ranch homes, the 1960s-era fibrous liner inside sheet-metal ducts has reached end of life. It delaminates, circulates into living spaces, and provides nesting material for rodents that find entry through aging foundation vents.
- Disconnected supply runs in crawl spaces. Mountain View’s crawl-space ductwork, never inspected during cosmetic remodels, frequently includes supply boots that have separated from trunk lines. Homeowners wonder why one room never heats properly; we find the duct blowing directly into dirt.
- Wildfire smoke particulate accumulation. The Santa Clara Valley’s bowl-like topography traps Northern California wildfire smoke each August through November, and Mountain View’s older systems with marginal filtration load PM2.5 year after year. Post-fire-season cleaning isn’t optional maintenance here; it’s recovery from repeated exposure events.
- Marine-layer humidity and mold in flex duct. Garden apartments along El Camino Real, built with 1970s-1980s flex duct, develop mold growth where the Bay’s marine layer keeps crawl-space humidity elevated. The outer plastic jacket looks intact; the inner liner is spotted with growth that circulates spores every time the fan kicks on.
Pricing for Air Duct Cleaning in Mountain View, CA
Most full residential systems in Mountain View run $350-$650. A supply-duct-only clean typically falls at $280-$420, while return-duct cleaning runs $220-$380. Complete commercial systems start around $800 and scale with square footage and access complexity. What moves you within these ranges? The number of vents, whether we find disconnected or damaged ductwork that needs sealing, and how long it’s been since the last cleaning. A Cuesta Park ranch home that hasn’t been opened in forty years takes longer than a five-year-old system in a Shoreline West townhome.
We give one flat price per system, agreed in writing before work starts. No per-vent pricing, no “we found an extra problem” charges at the door. Every estimate includes before-and-after photos of your own ducts, not stock images. Call (469) 972-3151 for your free estimate; we’ll ask about your home’s age, neighborhood, and any specific concerns, then give you a number that doesn’t change.

FAQs About Air Duct Cleaning in Mountain View
Yes. These homes typically retain original sheet-metal ductwork with fibrous internal liner that degrades after sixty-plus years, requiring gentler brush agitation and more thorough post-cleaning inspection for liner damage. The successive waves of tech-industry buyers who renovated every visible surface rarely touched the HVAC, so we often find systems that have never been professionally cleaned. Call (469) 972-3151 and we’ll scope your particular Cuesta Park system to see what condition it’s actually in.
The valley’s enclosed geography concentrates PM2.5 from Northern California wildfires each August through November, and standard HVAC filtration in older Rex Manor homes isn’t rated to capture these particles. They accumulate in ductwork, recirculate during winter heating season, and degrade indoor air quality for months after the smoke clears. Post-fire-season duct cleaning removes this accumulated load, and we can recommend appropriate Aprilaire filtration upgrades if your current system is underspecified.
The Bay’s marine layer penetrates further inland on these sides of town, maintaining higher crawl-space humidity than the drier south and west exposures. Uninsulated or poorly insulated ductwork in this persistent moisture develops condensation, then mold growth on the interior liner. We find this pattern repeatedly in garden apartments and older single-family homes alike, and cleaning alone isn’t enough; we identify where insulation or vapor barrier repair is needed to prevent recurrence.
We regularly find rodent debris predating the last crawl-space exclusion job, delaminated fibrous liner that’s begun to circulate into living spaces, and failed tape joints at every turn and connection. In one Rex Manor home last year, our camera revealed a completely disconnected supply boot that had been blowing heated air into the crawl space since approximately 1987. The homeowner had wondered for years why that bedroom was always cold. Camera inspection turns “maybe” into “here’s exactly what we’re looking at.”
Yes, and these systems often need it most. The 1970s-1980s flex duct common in these buildings degrades in Mountain View’s marine-layer humidity, developing mold spots and crush damage from decades of maintenance traffic in crawl spaces. We use lower-pressure negative-air extraction and softer brush agitation to avoid damaging the already-fragile inner liner, and we document condition carefully because these ducts often need replacement rather than repeated cleaning. Call (469) 972-3151 and we’ll assess whether cleaning is worthwhile or if you’re throwing money at a system that’s reached end of life.
