Air duct cleaning in Los Gatos typically runs $350-$850 for a full residential system, with most jobs completed in a single visit. Homes in the 95032 and 95033 hillside zones often land higher due to multi-level duct runs and access challenges.

We’ve been driving our trucks to Los Gatos since 1984. Our Air Duct Cleaning team knows the difference between a flatland ranch off Los Gatos-Almaden Road and a hillside custom build off Summit Road with ductwork that snakes through three levels. That local knowledge matters. It means we bring the right equipment, the right crew size, and the right expectations. We’re not figuring out your house when we arrive. We’re already working.
Los Gatos sits where the Santa Cruz Mountains meet the South Bay, and that geography shapes everything about your air ducts. The mountain-interface microclimate brings heavier rainfall and humidity than Campbell or San Jose just to the east. Live oak and mixed-chaparral woodland surround the town, pumping seasonal pollen through outdoor HVAC intakes. And the wildfire smoke - from the CZU Lightning Complex and before it, the Loma Prieta burn scars - settles into ductwork here more aggressively than anywhere else in the valley. We’ve cleaned systems in Los Gatos that looked like they’d been filtering a campfire for months.
Why Bellows Air Duct & Vent Co. Is Los Gatos’s Preferred Air Duct Cleaning Company
Forty-two years in business means we’ve earned the repeat calls from Los Gatos homeowners. They refer us to neighbors on Tait Avenue and up in the Rinconada hills. Our reviews from Los Gatos customers consistently mention the same things: we show up when we say, we explain what we found, and we leave the house cleaner than we found it.
Our response time to Los Gatos is same-day or next-day for standard bookings, and we keep slots open for urgent calls - especially during active wildfire smoke events when your system is recirculating particulates you can smell. Calls are answered by a live person, 24 hours a day. Not a voicemail tree. Not an app. A real person who can dispatch a crew.
We know the local building stock cold. The pre-WWII craftsman bungalows in the 95030 downtown core with their original plaster and tight chases. The mid-century ranch homes with single attic trunks. The 1970s-1990s hillside builds off Kennedy Road and Black Road with bonus rooms over garages, vaulted ceilings, and duct layouts that look like they were drawn by a surveyor with a sense of humor. Each type demands a different approach, and we adjust before we arrive.

Our Air Duct Cleaning Services in Los Gatos
Residential Duct Cleaning
Most Los Gatos homes we clean fall into three categories, and we treat each differently. The historic downtown bungalows need gentle handling around original features - plaster walls, vintage grilles, sometimes asbestos-wrapped ducts from mid-century updates. The flatland ranches and townhomes off Winchester Boulevard have straightforward attic systems, though many have been modified with additions that create dead zones. The hillside homes in 95032 and 95033 are the heavy lifts: multi-level duct runs, flex-duct crawling through crawlspaces with limited clearance, and the wildfire smoke loading that adds an extra layer of particulate to every surface.
Our residential cleanings include full system agitation with Rotobrush equipment, HEPA-filtered vacuum collection, and a complete video inspection you can watch with us. Most jobs finish in four to six hours. One visit. Done right - and backed in writing for 90 days.
Commercial Duct Cleaning
Los Gatos’s commercial base runs from professional offices along North Santa Cruz Avenue to restaurant kitchens and small medical suites. Each has different code requirements and occupancy schedules. We work around your hours, not ours. Our commercial crews use Nikro and Abatement Technologies equipment scaled for larger static pressure systems, and we document everything for your insurance or lease compliance. No disruption to your customers.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Los Gatos they’re often the first place we find problems. The hillside homes with cathedral ceilings have extended supply runs that sag or separate at joints, dumping heated or cooled air into wall cavities instead of living spaces. We see this constantly in the 95033 zone. Our supply duct service includes pressure testing to identify leaks, mechanical brushing of the full run, and sealing with mastic where joints have failed. You’ll feel the difference in room-to-room airflow immediately.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re the entry point for everything Los Gatos throws at your system: oak pollen in April and May, wildfire smoke particulates in late summer and fall, and the higher humidity that can start microbial growth on duct walls. Return duct cleaning is where we often find the heaviest loading, especially in homes with undersized or poorly maintained intake filters. We clean the full return path, including the plenum and filter rack, and we’ll tell you honestly if your filter schedule needs tightening.
Full System Cleaning
This is our most comprehensive service, and it’s what most Los Gatos hillside homes need. Full System Cleaning covers every duct - supply and return - plus the air handler cabinet, blower assembly, evaporator coil (if accessible), and register grilles. We bring Rotobrush systems, HEPA vacuums, and compressed air tools. For the complex multi-level layouts common off Summit Road and Black Road, we’ll map the system first and verify flow at every vent afterward. Camera inspection before and after. One honest price shown before we start.
Video Inspection
Every Bellows job includes video inspection - before, to show you what we’re dealing with, and after, to prove it’s clean. In Los Gatos, this matters more than most places. We’ve had homeowners watch live footage of ducts caked with gray wildfire ash they didn’t know was there. We’ve shown them disconnected flex-duct joints pulling crawlspace air into their bedrooms. The camera doesn’t lie, and we don’t ask you to trust us without seeing it.

No second appointment window.
Common Air Duct Cleaning Problems We See in Los Gatos Homes
- Disconnected flex-duct joints under hillside homes. Soil creep in the 95033 foothill zone pulls apart flex-duct connections in crawlspaces over time. We regularly find gaps pulling smoky, pollen-laden air from below the house straight into living areas. Our crew tackled a hillside home off Kennedy Road where exactly this was happening - disconnected runs from years of soil movement were circulating crawlspace air the owners could smell. We scrubbed every duct with a Rotobrush system and sealed each joint with mastic. The musty smoke odor they’d lived with since the CZU fires finally cleared.
- Wood-smoke residue from primary wood stoves. Many 95033 mountain-zone homes were built outside SoCalGas territory and still heat with wood stoves. The smoke residue hardens into tar-like deposits that standard vacuuming won’t touch. We use mechanical agitation and solvent-safe cleaning to break it loose, then HEPA extraction to remove it completely.
- Overloaded outdoor intake filters during oak pollen season. Los Gatos’s live oak canopy generates pollen loads that surprise newcomers. Filters clogged in April lead to bypass airflow that dumps unfiltered pollen directly into ductwork. We clean the full intake path and will tell you if your filter MERV rating or change schedule is wrong for this environment.
- Wildfire smoke particulate accumulation in HVAC systems. The CZU Lightning Complex burned terrain immediately adjacent to Los Gatos, and subsequent fire seasons have sent smoke through these hills repeatedly. Standard filters don’t catch the fine particulates. They settle in ductwork and recirculate for months. Full system cleaning with HEPA containment is the only way to remove it.

FAQs - Air Duct Cleaning in Los Gatos
Every two to three years for most Los Gatos homes, but annually if you’re in the 95033 foothill zone with active wildfire smoke exposure or severe oak pollen sensitivity. The mountain-interface conditions here - heavier pollen loads and recurring smoke infiltration - accelerate particulate buildup faster than comparable homes in San Jose or Campbell. Call (844) 685-6342 and we’ll assess your specific exposure and system condition - estimates are free.
Yes, if the odor is coming from residue inside your ductwork. Wood-smoke tar deposits in supply and return ducts recirculate every time your HVAC runs. We use mechanical agitation to break the residue loose and HEPA extraction to remove it completely. If the smell is coming from porous building materials - unsealed framing, for example - duct cleaning alone won’t solve it, and we’ll tell you that before we start. Call (844) 685-6342 for an inspection - estimates are free.
Yes. These are precisely the homes we specialize in. Summit Road, Black Road, Kennedy Road - we’ve cleaned ductwork in all of them. The non-linear layouts, extended flex-duct runs, and limited crawlspace access are standard conditions for our hillside crews. We bring Rotobrush systems with extension shafts and compact HEPA vacuums that fit where standard equipment won’t. Most jobs still complete in one visit. Call (844) 685-6342 to schedule - we’ll confirm crew size and equipment before we arrive.
Yes. The 95030 historic core has homes with plaster walls, vintage metal grilles, and sometimes fragile asbestos-wrapped ducts from mid-century updates. We adjust our methods: softer brush heads, hand-cleaning around sensitive fittings, and no aggressive agitation near original materials. Our camera inspection lets us see what we’re working with before we touch anything. We’ve cleaned dozens of these homes without a single callback for damage. Call (844) 685-6342 - we’ll walk through your specific concerns.
Upgrade to a MERV 13 or higher pleated filter, change it every 60 days during pollen season (March through June), and consider an Aprilaire media air cleaner if your system can handle the static pressure. We also recommend sealing duct leaks - especially in hillside homes where crawlspace and attic connections pull unfiltered air - and scheduling a full system cleaning after major wildfire smoke events. Call (844) 685-6342 and we’ll evaluate your current setup - estimates are free.
