Fast, Reliable Air Duct Cleaning Across Los Altos
Air duct cleaning in Los Altos typically costs $350–$850 for a full residential system, with most jobs completed in a single visit. We’re usually on-site within 45 minutes to Los Altos from our base, and Richard Anderson personally leads every job — not a subcontractor you’ve never met.
We’ve been cleaning ducts in Los Altos since 2011, and we’ve learned this city’s air quality problems aren’t like Mountain View’s or Sunnyvale’s. The 94022, 94023, and 94024 ZIP codes are dominated by mid-century ranch homes with original ductwork that’s now pushing 60 or 70 years old. That vintage sheet-metal and fiberglass-lined infrastructure, combined with Los Altos’s relentless renovation cycle, creates a cleaning challenge you won’t find in newer Peninsula developments. Our Air Duct Cleaning team knows these systems inside and out — literally. When your 1968 forced-air trunk lines are packed with drywall compound from last year’s kitchen expansion, you need someone who’s dealt with that exact scenario before.

Why Landmark Air Duct Cleaning Service California Is Los Altos’s Preferred Air Duct Cleaning Company
Los Altos homeowners don’t hire us because we’re the cheapest option. They hire us because Richard Anderson shows up — not a crew you’ve never met. Over 14 years focused exclusively on air duct and HVAC cleaning, we’ve earned a 4.9-star average across 364+ verified customer reviews, and a significant share of those come from repeat clients in the Country Club, Loyola Corners, and South Los Altos neighborhoods.
Our response time to Los Altos averages under an hour because we know these streets: Foothill Expressway to El Monte Avenue, Magdalena to Springer Road. We understand that a Los Altos home listed at $3.5 million with original 1962 ductwork needs a different approach than a 2019 build in a nearby city. Richard’s walked hundreds of these crawl spaces and attics. He knows which ’60s tracts used rigid fiberglass trunk lines versus sheet-metal branch ducts, where the access panels typically are, and what post-remodel debris patterns to expect.
That local fluency matters when you’re deciding whether a 55-year-old system needs cleaning or replacement. We give straight answers — no upselling, no scare tactics.
Our Air Duct Cleaning Services in Los Altos
Residential Duct Cleaning
Los Altos’s housing stock is almost entirely single-story and split-level ranch homes built between 1950 and 1975. Many still contain original forced-air trunk-and-branch systems with deteriorating fiberglass duct liner. Our residential cleaning process starts with a video inspection to assess liner condition, then uses Rotobrush rotary agitation and Nikro negative-air HEPA extraction to remove built-up particulate without damaging fragile vintage components. We clean the full supply and return network, including registers, boots, and the main plenum.
Commercial Duct Cleaning
While Los Altos is overwhelmingly residential, we do handle select commercial properties along San Antonio Road and in the small professional office clusters near downtown. These buildings — often converted ’70s structures — present their own challenges: mixed metal-and-flex duct transitions, aging rooftop units, and occupancy schedules that demand weekend or early-morning work windows. We coordinate directly with property managers to minimize disruption.
Supply Duct Cleaning
Supply ducts push conditioned air into your living spaces, and in Los Altos’s original ranch homes, these branch lines are typically 6-inch round sheet metal with deteriorating fiberglass liner. When that liner fragments, glass fibers enter your airstream. Our supply duct cleaning uses controlled rotary brushing with simultaneous HEPA vacuum extraction, capturing dislodged debris at the point of contact rather than blowing it into your home. We pay particular attention to register boots, where remodel dust tends to accumulate thickest.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and in Los Altos’s older homes, these are often oversized sheet-metal trunks running through unconditioned attics or crawl spaces. The return side is where we most often find post-construction debris — drywall dust, insulation fragments, even dropped fasteners from decades of attic work. Our return cleaning includes the return grille, filter rack, and trunk line, with video verification that the path is clear.
Full System Cleaning
Most Los Altos jobs require full system cleaning — supply, return, and HVAC components together — because debris migrates throughout interconnected vintage ductwork. A partial cleaning often leaves contamination that re-spreads within weeks. Our full system service includes the air handler cabinet, blower wheel, evaporator coil (accessible), and condensate pan, plus sanitizing treatment with Guardsman-approved products.
Video Inspection
Video inspection is non-negotiable for Los Altos’s aging housing stock. We feed a high-resolution camera through your ductwork to document liner condition, seam integrity, and debris loading before we quote any work. This protects you from paying for cleaning when replacement is the honest recommendation — and it protects us from surprises mid-job. On a recent job in the Country Club neighborhood, we encountered a 1963 ranch home where the homeowners had just completed a $200,000 kitchen remodel. Our crew used a Rotobrush system to extract over 15 pounds of drywall dust and fiberglass particles from the original trunk-and-branch ducts, which had deteriorated liner causing poor airflow and IAQ complaints. The video inspection beforehand made the scope clear to everyone.

Trusted Brands We Service in Los Altos
We run professional-grade Rotobrush and Nikro equipment on every Los Altos job — the same rotary brush and negative-air extraction systems used by commercial restoration contractors, not consumer-grade shop-vac setups with brush attachments. For air quality components and sanitizing treatments, we work with Honeywell and Aprilaire filtration and humidification products when upgrades make sense. We don’t name-drop brands to impress you; we name them because they’re what actually sits in our van, what Richard Anderson has trained on for 14 years, and what produces measurable results in 1960s ductwork that doesn’t forgive amateur mistakes.
Common Air Duct Cleaning Problems We See in Los Altos Homes
- Fiberglass duct liner fragmentation: Original liners from the 1960s shed glass fibers into the airstream, requiring full system cleaning with HEPA vacuuming to prevent respiratory irritation in residents. We see this in roughly half the pre-1975 homes we inspect in Los Altos.
- Post-remodel drywall dust compaction: Fine gypsum powder from kitchen and bath remodels settles deep into ductwork, often missed by standard cleaning if not pre-scheduled, leading to dust blow-out when heat kicks on. Contractors pulling permits for Los Altos remodels have increasingly pre-scheduled post-construction duct cleaning as a standard project close-out step.
- Sheet-metal seam separation: Overheated sections in attics can cause duct joints to pull apart, bypassing cleaning efforts; our video inspection locates hidden separations before we start any work.
- Wildfire smoke residue accumulation: Back-to-back severe wildfire smoke seasons since 2017 have deposited fine particulate throughout Los Altos duct systems, particularly on the return side where outside air infiltration occurs.

FAQs — Air Duct Cleaning in Los Altos
Los Altos duct cleaning is more intensive because nearly all homes built between 1950 and 1975 still have original fiberglass-lined ductwork, and the city’s sky-high property values make extensive remodels routine, generating a constant stream of construction debris that these aging ducts trap. Neighboring cities with newer construction or more commercial land use simply don’t face this pairing of vintage infrastructure and perpetual renovation activity. The result: heavier debris loads, more fragile liner to work around, and a higher baseline need for video inspection before any cleaning begins. Call (833) 958-5022 for a free estimate — we’ll show you exactly what your system looks like inside.
Yes, post-remodel duct cleaning is strongly recommended for any kitchen, bath, or addition project in a 1960s Los Altos home. Drywall compound, insulation fragments, and sawdust enter your duct system through open registers and return grilles during construction, then compact into existing debris layers in original fiberglass-lined ducts. We’ve extracted 10–20 pounds of post-construction material from single systems. Many Los Altos general contractors now pre-schedule this as a standard close-out step because inspectors and buyers flag dust-packed registers in walkthroughs of premium homes. Call (833) 958-5022 to coordinate timing with your contractor.
Video inspection is the only reliable way to distinguish cleanable debris from failed duct liner or separated seams that require replacement. If your fiberglass liner is actively shedding fibers, smells musty, or shows widespread detachment from the metal substrate, cleaning alone won’t solve the problem — and may make it worse by agitating loose material. Richard Anderson will show you the camera feed and explain what he’s seeing in plain terms. If replacement is the honest call, we’ll tell you. If cleaning will get you five more years, we’ll tell you that too. Call (833) 958-5022 to schedule an inspection.
We use Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air HEPA extraction systems for debris collection on every Los Altos job. For filtration upgrades and air quality treatments, we work with Honeywell and Aprilaire components when appropriate for your system. These are commercial-grade tools, not consumer shop-vac attachments, and they’re specifically suited to the challenges of 50–70-year-old ductwork where overly aggressive cleaning can damage fragile components. Call (833) 958-5022 to discuss what your specific system needs.
Yes, our full system cleaning with HEPA extraction removes wildfire smoke particulate that has accumulated in Los Altos ductwork since the severe smoke seasons beginning in 2017. Fine smoke particles deposit heavily on return duct surfaces and blower components, then redistribute into living spaces during heating and cooling cycles. We target these deposits with extended contact time during rotary brushing and verify removal with post-cleaning video inspection. For households with respiratory sensitivities, we can follow cleaning with an air sanitizing treatment. Call (833) 958-5022 to discuss whether your system shows smoke residue loading.
