Fast, Reliable Air Duct Cleaning Across Los Gatos
Professional air duct cleaning in Los Gatos typically runs $350–$850 for a full residential system, with most jobs completed in a single visit. Richard Anderson personally leads every job as owner and lead technician — you’ll never get handed off to an anonymous crew when you call Landmark Air Duct Cleaning Service California at (833) 958-5022. We know Los Gatos from the flatland ranch neighborhoods along Los Gatos-Almaden Road to the winding hillside streets off Summit Road, and we bring 14 years of focused duct-cleaning experience to every home we service.

Los Gatos presents a unique combination of challenges you won’t find in neighboring Campbell or Cupertino: wildfire smoke residue from the 2020 CZU Lightning Complex fires, earthquake-disturbed duct systems dating back to 1989, and marine-layer humidity that breeds mold in crawlspaces. Our Air Duct Cleaning team addresses all of it with professional Rotobrush and Nikro equipment — the same systems commercial restoration contractors use, not a shop vac and a sales pitch.
Why Landmark Air Duct Cleaning Service California Is Los Gatos’s Preferred Air Duct Cleaning Company
Richard shows up — not a crew you’ve never met. Owner Richard Anderson serves as lead technician on every Los Gatos job, which means the person quoting your work is the same person crawling your attic or crawlspace to do it. That personal accountability matters in a town where homes often carry premium finishes and custom-built systems that demand careful handling.
Our 4.9-star average across 364+ verified reviews reflects consistent, repeatable execution — not a handful of cherry-picked testimonials. Los Gatos homeowners specifically mention our thoroughness with older duct systems and our willingness to explain what we find during video inspections. We’re based in Bell, CA, with response times that keep us competitive throughout the South Bay, including same-week scheduling for most Los Gatos addresses.
We understand the local housing stock intimately: the 1950s–1970s post-war ranches clustered near downtown Los Gatos (ZIP 95030 and 95032) with their original sheet-metal ductwork and degrading fibrous liner; the custom hillside homes in 95033 with convoluted crawlspace runs that generalist cleaners often refuse to touch. Fourteen years focused on one trade means we’ve seen the specific failure modes this town produces.
Our Air Duct Cleaning Services in Los Gatos
Residential Duct Cleaning in Los Gatos
Los Gatos homes demand precision. In the flatland neighborhoods near Los Gatos High School and along Tait Avenue, we regularly clean post-war ranch systems where the original fibrous duct liner has begun shedding particles into living spaces — a problem that develops gradually and often gets mistaken for general dust. Our residential process includes full supply and return cleaning, register removal and hand-cleaning, and debris extraction with HEPA-filtered Nikro negative-air systems. For hillside homes off Old Santa Cruz Highway or Black Road, we factor in extended access time for crawlspaces with limited clearance.
Commercial Duct Cleaning in Los Gatos
Los Gatos’s commercial base — professional offices along North Santa Cruz Avenue, retail near the Village, and smaller medical practices — requires minimal disruption to operations. We schedule around your business hours and use contained Rotobrush systems that limit airborne disturbance during cleaning. Richard Anderson personally assesses each commercial system to determine whether negative-air extraction or rotary brush cleaning better serves your duct configuration and occupancy patterns.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms, and in Los Gatos they’re particularly vulnerable to the fine ash infiltration that occurred during the 2020 wildfire evacuations. Homes in 95033 especially — where smoke seeped through building envelopes while systems sat idle for weeks — often show distinctive gray-white particulate accumulation on supply duct interior surfaces. Our supply duct cleaning targets this residue specifically, using rotary brush agitation followed by immediate HEPA vacuum extraction so particles don’t redistribute into your home.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re the first place we find evidence of long-term neglect: compacted dust, pet hair, and in Los Gatos’s humid crawlspaces, mold colonies on interior duct liner. The return side also reveals how much debris your filter has been missing. We clean return trunks, drop boxes, and boot connections, then verify airflow improvement with before-and-after visual documentation.
Full System Cleaning
A full system cleaning addresses every component — supplies, returns, trunk lines, plenums, and the air handler itself. In Los Gatos, this is our most recommended service for homes that haven’t had professional duct cleaning in five-plus years, particularly those in 95030 and 95032 with original post-war ductwork. The comprehensive scope catches interconnected problems: a degraded return liner shedding particles that clog the air handler, or earthquake-loose supply connections leaking conditioned air into attics.
Video Inspection
Our video inspection service uses flexible borescope cameras to document duct interior conditions before and after cleaning. For Los Gatos hillside homes with long, convoluted crawlspace runs in 95033, this is often the only way to verify that wildfire smoke residue has been fully removed from inaccessible sections. We share the footage with you directly — no vague claims, no hidden areas.

Trusted Brands We Service in Los Gatos
We work with Honeywell and Aprilaire air quality components regularly found in Los Gatos homes — whole-house media filters, electronic air cleaners, and humidifier attachments integrated into duct systems. Our Rotobrush and Nikro equipment is compatible with these systems, and we stock common replacement media and Guardsman sanitizing treatments for same-visit completion when your duct cleaning reveals a failed or saturated component. That means no waiting on parts shipments while your system sits open.
Common Air Duct Cleaning Problems We See in Los Gatos Homes
- Wildfire smoke residue in 95033 mountain homes. The 2020 CZU Lightning Complex fires burned the Santa Cruz Mountains surrounding Los Gatos, and smoke infiltrated duct systems while homes sat evacuated for weeks. The resulting fine-ash accumulation is visually distinctive — gray-white, slightly oily — and conventional cleaning without HEPA containment can redistribute it into living spaces.
- Degrading fibrous duct liner in post-war ranches (95030/95032). The 1950s–1970s ranch homes that dominate Los Gatos’s flatland neighborhoods often retain original ductwork with fibrous interior insulation that breaks down over decades, shedding particles that resemble coarse dust but are actually degraded liner material. A video inspection usually reveals the extent.
- Marine-layer humidity promoting mold growth. Fog pushing inland through mountain gaps raises overnight humidity in Los Gatos crawlspaces and unconditioned attics above levels common in drier Campbell or Cupertino. We find mold on duct interior liner more frequently here than in flatland South Bay cities, particularly in homes with dirt-floor crawlspaces.
- Earthquake-loose duct connections from 1989 Loma Prieta. The epicenter sat roughly 10 miles from downtown Los Gatos, and the ground-shaking rattled duct joints and disturbed insulation in mid-century homes. Decades later, these loosened connections leak conditioned air and draw in crawlspace contaminants — a slow efficiency drain that homeowners rarely trace to its source.
Pricing for Air Duct Cleaning in Los Gatos, CA
| Service | Typical Range in Los Gatos |
|---|---|
| Residential duct cleaning (up to 10 vents) | $350–$550 |
| Residential duct cleaning (11–20 vents) | $550–$850 |
| Full system cleaning with air handler | $650–$1,100 |
| Video inspection (standalone or add-on) | $150–$250 |
| Dryer vent cleaning (with duct service) | $75–$150 |
| Commercial duct cleaning (per sq ft) | $0.25–$0.45 |
What moves you within these ranges? Vent count matters most — a compact 95030 ranch with eight vents sits at the lower end, while a sprawling 95033 custom home with twenty-plus vents and extended crawlspace runs requires more labor and equipment time. Accessibility is the second factor: hillside homes with limited crawlspace clearance or buried duct runs take longer to service properly. Wildfire smoke residue removal adds HEPA containment steps that standard cleaning doesn’t require. We provide exact, itemized quotes before any work begins — call (833) 958-5022 for your free estimate.

FAQs — Air Duct Cleaning in Los Gatos
Smoke infiltration during the three-to-six-week evacuation period left fine particulate ash inside duct systems that is visually distinctive — gray-white, slightly oily, and immediately recognizable to 95033 homeowners who experienced it. Standard cleaning without HEPA-filtered negative-air containment risks redistributing this residue into living spaces, which is why we use Nikro HEPA vacuum systems and sealed Rotobrush containment on every Los Gatos mountain-area job. Call (833) 958-5022 to schedule an inspection if your 95033 home hasn’t had professional duct cleaning since 2020.
The 1950s–1970s ranch homes dominating these ZIP codes typically retain original sheet-metal duct systems with fibrous interior insulation that degrades and sheds particles after 40–60 years of thermal cycling. This degraded liner resembles coarse household dust but is actually structural material breaking down, and it bypasses standard filters because it originates inside the duct itself. Video inspection is the only reliable way to assess the extent; we recommend it for any Los Gatos ranch home with original ductwork. Call (833) 958-5022 for a free estimate.
Yes — the 1989 earthquake’s ground-shaking loosened duct joints, disturbed insulation, and shifted register boots in Los Gatos’s mid-century housing stock, and many of these issues were never professionally assessed because they didn’t cause immediate HVAC failure. Decades later, these loosened connections leak conditioned air into attics and crawlspaces while drawing in contaminants, producing the dual problem of higher energy bills and poorer indoor air quality. Our full system inspection includes connection-point assessment for earthquake-related loosening. Call (833) 958-5022 to schedule.
Marine-layer fog pushing through Santa Cruz Mountain gaps raises overnight humidity in Los Gatos crawlspaces and unconditioned attics above levels typical in drier Campbell or Cupertino, creating conditions that promote mold and mildew growth on interior duct liner. This moisture-driven mold is less common in flatland South Bay cities and frequently overlooked by generalist cleaners who don’t factor local microclimate into their assessment. We inspect for biological growth as standard practice on every Los Gatos job. Call (833) 958-5022 for an evaluation.
Yes — video inspection is standard on our hillside jobs in 95033, where custom homes often feature long, convoluted crawlspace duct runs that are impossible to assess visually without borescope equipment. On a recent job in the 95033 mountain area, we cleaned a custom-built home where the 2020 wildfire smoke had settled into the duct liner during three weeks of evacuation. Using our Rotobrush system and HEPA-filtered Nikro vacuum, we removed the telltale ash layer and restored the home’s indoor air quality to match its premium finishes. We provide the footage directly to you, before and after. Call (833) 958-5022 to schedule.
