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.

AfterAir Duct Cleaning Company in Los Altos, CA
Los Altos is a city where a seven-figure home often sits on 50-year-old ductwork. The mid-century ranch houses that define this town were built between the late 1950s and early 1970s, and while kitchens and bathrooms have been beautifully renovated, the original sheet-metal and early flex ducts are usually still in place, carrying decades of accumulated debris. We’re Kestrel Air Duct Cleaning, and we work on those older systems every week. If you’re seeing dust settle back onto furniture within days of cleaning, or your HVAC runs louder than it used to, call us at (469) 972-3151 for a written estimate before any work begins.
Why Los Altos Homes Are Different
Most Los Altos homes are single-story California ranch construction from roughly 1955 to 1975. Duct runs typically snake through low-clearance attic spaces or raised-foundation crawlspaces, which makes access tight and inspection work slow. More importantly, the city’s property values have pushed homeowners toward aggressive interior renovations rather than teardowns, so the duct infrastructure behind an updated kitchen is often original: deteriorating duct-board interiors, failing flex connections, and joints that have been leaking conditioned air into the attic for years.
Then there’s the environmental factor. Los Altos sits directly downwind of the Los Altos Hills fire corridor, and Diablo wind events during fall wildfire season push fine ash and combustion particulates into return air intakes throughout the city. Those particles embed in aging duct lining in ways a filter change never touches. Add the dense mature-oak canopy that generates heavy seasonal pollen loads, and you get HVAC systems that circulate a surprising amount of biological material even while running only intermittently in the mild climate. Homes near Loyola Corners and along the Foothill Expressway corridor show this pattern more than most.
Our Main Los Altos Services
Los Altos homeowners call us most often for two jobs: full air duct cleaning and dryer vent cleaning. Each has its own dedicated Los Altos page with pricing, process details, and what to expect.
Air Duct Cleaning in Los Altos
Air duct cleaning in Los Altos usually means working inside ranch-style attic runs where decades of dust, pollen, and wildfire ash have built up in original duct-board interiors. We often find that homeowners near the Foothill Expressway corridor upgraded to high-MERV filtration without addressing the ductwork itself, which restricts airflow and can cause flex duct sections to partially collapse in attic runs. Our process uses negative-air extraction, which means we pull contaminants out of the ducts under vacuum rather than pushing them around, and brush agitation to dislodge debris stuck to the duct walls. Read the full breakdown on our Air Duct Cleaning in Los Altos page.
Dryer Vent Cleaning in Los Altos
Dryer vent cleaning matters in Los Altos because the same wildfire ash that gets into HVAC returns also enters dryer vent terminations, especially during fall Diablo wind events. Lint mixed with fine ash compacts faster and clogs sooner than lint alone, which means longer dry cycles and a real fire risk. When we clean a dryer vent, we perform a lint trap bypass, which means we go past the lint screen you pull out of the machine and clean the full run to the exterior termination. Full details on our Dryer Vent Cleaning in Los Altos page, including how we verify the work is actually done.

Two things push prices up in Los Altos specifically: tight attic clearances that make every tool and technician movement slower, and flex duct sections that have partially collapsed from restricted airflow, which means repair work on top of cleaning. Regardless of what we find, the price you approve in writing is the price you pay. No revised quote at the door, no surprise line items. That’s the Kingswell Way.

Air duct and dryer vent cleaning does not require a city permit in Los Altos. If your home is in an HOA, a quick check of your CC&Rs is the only step you might need, but most Los Altos HOAs treat interior ductwork as homeowner responsibility. We’ve never had a job held up by HOA rules.

What Los Altos Customers Say
"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
