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 Los Altos
Air duct cleaning in Los Altos typically costs $380 – $690 for a full single-family system, depending on home size and how many decades of debris have settled into the crawl-space runs. Most jobs we complete in one visit, and every homeowner gets a written price before we touch a duct. If you’re noticing dust at the registers, a musty smell when the HVAC kicks on, or you just bought a mid-century ranch with original ductwork, call Linden Air Duct Cleaning at (980) 447-2498. We know Los Altos homes because we work in them every week.
Los Altos is not like Sunnyvale or Mountain View when it comes to what’s inside your ducts. The housing stock here skews older, the crawl spaces are tighter, and the city’s position at the base of the Santa Cruz Mountains changes what accumulates in your air system. We’ll explain exactly what that means for your home, what it costs to fix properly, and what you should not pay for.
Why Linden Air Duct Cleaning Is Los Altos’s Preferred Air Duct Cleaning Company
Linden Air Duct Cleaning has been serving homeowners since 2004 as part of the Threshold Group family, and our Los Altos customers keep us busy for a reason: we tell you who’s coming to your door before they arrive. Every technician is background-checked and identity-verified, and you receive the tech’s name and photo before the visit. When they show up in a marked uniform, they’ll show a photo ID badge at the door. That’s the Threshold Standard, and it’s not optional on any job we run in Los Altos.
We also put the price in writing before work begins. No per-vent pricing games, no surprise invoice at the end. If a repair doesn’t hold, the 365-Day Done Right Promise means we come back and make it right, in writing, on every job. Marcus Veale leads our team, and he holds every Los Altos job to the same standard: the system gets genuinely clean, or we’re not done.

HVAC Duct Cleaning in Los Altos
HVAC Duct Cleaning in Los Altos means pulling decades of accumulated particulate out of supply and return runs that, in many homes here, date back to the Eisenhower and Kennedy administrations. A typical single-story ranch in neighborhoods like Woodland Acres or the streets off Loyola Drive runs $380 – $690 for a complete system clean, including the air handler, supply ducts, return ducts, and register covers. Homes with two systems or major crawl-space access challenges land at the higher end.
The job itself is straightforward to describe but demanding to do right. We connect HEPA-filtered negative-pressure equipment to the main trunk at the air handler, then agitate every supply and return run with air whips and rotary brushes. Negative pressure means the dislodged debris gets pulled to the collection unit outside, not blown back into your living room. It’s the difference between cleaning a duct and just rearranging dust.
Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace or air handler to each room. In Los Altos, these often run through uninsulated crawl spaces where fine wildfire-ash particulate settles and compacts over time. Our agitation tools reach the full length of each supply run, not just the first few feet visible from the register.
Return Duct Cleaning
Return ducts pull air back from your living space to be reconditioned. In Los Altos ranches, return runs frequently pick up rodent nesting material, especially where joints have separated in low-clearance pier-and-beam crawl spaces. We clean and inspect every return run so air moving through the system isn’t carrying what a roof rat left behind.
Vent Cleaning in Los Altos
Vent Cleaning in Los Altos covers the register covers, grilles, and visible duct openings throughout the house, plus the deeper runs behind them. A full vent cleaning across a 1,800 – 2,400 square foot Los Altos ranch runs $180 – $320 as part of a complete system job; standalone vent work on smaller homes lands at the lower end. If the register covers are caked with grey film from fire seasons, that’s a sign the runs behind them need attention too.
We remove each register cover, clean the visible boot, and push agitation tools as far as the run allows. Where access is tight, we use camera inspection to verify what got cleaned and what didn’t. Los Altos homes with original mid-century registers often have debris packed into the boot itself, so we spend extra time on the point where the run meets the floor.
Video Inspection
After cleaning, we run a camera through the main trunk and branch lines so you can see the interior condition with your own eyes. Photographic proof matters here: you hired a duct cleaning, and you should know exactly what got removed and what the ducts look like when we’re finished.
Trusted Brands We Service in Los Altos
We run professional-grade Rotobrush and Nikro equipment on every job, paired with HEPA filtration so dislodged particulate leaves the house instead of settling into the carpet. For post-cleaning air quality, we work with products from Abatement Technologies and Guardsman. Because so many Los Altos homes use original mid-century branch-line layouts, we carry common trunk and boot fittings in the van, which keeps turnaround tight when a rusted boot or split seam needs re-sealing during the job.
Common Air Duct Cleaning Problems We See in Los Altos Homes
- Rodent debris in crawl-space ducts. Los Altos’s pier-and-beam foundations give roof rats and mice easy access to duct joints for years. Nesting material, droppings, and chewed insulation are common in homes off Foothill Expressway and throughout the South Los Altos corridor.
- Wildfire smoke particulate from Santa Cruz Mountains fires. The 2020 SCU Lightning Complex blanketed this corridor with fine grey ash that settled into HVAC systems. We still find layers of that smoke residue in ducts we clean in 2026.
- Original 1950s – 1960s flex-duct failure. Early flex duct deteriorates where it enters the air handler and where it connects to metal boots. Torn inner liners leak conditioned air into crawl spaces and pull in dust from below the house.
- Restricted return airflow. Rooms with a single small return register and a partially collapsed return run struggle to move air. Homeowners notice uneven heating or cooling and a stuffier feel in the back bedrooms of Los Altos’s long ranch floor plans.
Pricing for Air Duct Cleaning in Los Altos, CA
Here’s what Los Altos homeowners can expect. Full system cleaning for a single-family ranch runs $380 – $690. Dryer vent cleaning adds $120 – $180. Supply-only or return-only jobs on smaller homes start around $280. A fogging ‘sanitiser’ add-on that a competitor offers for $150 or $200 is not something we sell, because it does not remove the material causing the problem. We’ll show you before-and-after video of your own ducts so you can see what the money actually bought. Call (980) 447-2498 for a free estimate with a written price before any work begins.

FAQs About Air Duct Cleaning in Los Altos
Yes, in most cases. Los Altos sits at the base of the Santa Cruz Mountains, where wildfire smoke from events like the 2020 SCU Lightning Complex settles and lingers more heavily than in flatland cities to the east. Combined with pier-and-beam crawl spaces that allow rodent access to duct runs, Los Altos systems accumulate more material, faster. We recommend a camera inspection before deciding how often to clean your particular system. Call (980) 447-2498 and we’ll walk you through what we look for.
No. A fogging treatment mists the interior surfaces but does not remove the material feeding the odor: rodent nesting debris, settled smoke particulate, and years of compacted dust. As soon as moisture levels shift, the smell returns. Source removal using negative-pressure extraction is what actually eliminates the problem, and that’s what we do. If a competitor’s cheap quote includes a fogging ‘sanitiser’ as the headline fix, ask them how they plan to remove what’s physically inside the ducts.
We remove it mechanically, then sanitize the surfaces. After establishing negative pressure at the air handler, we agitate each run to break loose nesting material and droppings, then re-seal or replace compromised duct sections at the joints. In Los Altos’s low-clearance crawl spaces, this often means working from outside access points and using camera inspection to verify no material remains. We also note entry points so you can address the rodent access itself.
Yes. Fire smoke particulate settles into duct runs and keeps circulating through your living space whenever the blower runs, even years after the fire event. If you haven’t had the system cleaned since 2020, that fine grey residue is still there. Los Altos homes that went through the SCU Lightning Complex smoke need source removal at least once, and a camera inspection will confirm what’s inside. Call (980) 447-2498 to schedule an inspection.
MERV 8 to MERV 11 is the right range for most Los Altos ranch homes. Higher ratings can restrict airflow on older single-speed air handlers, which most mid-century ranches still run. After we clean your ducts, we’ll recommend a filter rating that balances particle capture with your system’s airflow capacity. If you’re using a MERV 13 or higher on an original 1960s blower, you may be stressing the motor.
If you live in Los Altos and your ducts haven’t been inspected in years, call Linden Air Duct Cleaning at (980) 447-2498. We’ll give you a written price before any work starts, send you the tech’s name and photo before the visit, and show you proof of the work when it’s done.
