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.
Air Duct Cleaning Company in Los Altos, CA
Air duct repair in Los Altos usually comes down to one recurring problem: homes that grew faster than their ductwork. A 1960s ranch gets a family-room addition in the 1990s, then a second-story primary suite a decade later, each project adding new flex runs spliced onto original rigid sheet metal in a low-pitch attic never designed for the load. The result is disconnected runs, crushed returns, and rooms that never quite heat or cool. We open every Los Altos job by mapping what’s actually there, then cleaning, repairing, or replacing what the house actually needs. Call (833) 620-7085 for an honest assessment first.
Why Los Altos Homes Are Different
Los Altos was largely built between 1955 and 1975, when California ranchers and Eichler-inspired designs dominated new construction. Those homes came with rigid sheet-metal ducts in cramped, low-clearance attics, and many later remodels added flex duct runs on top of, around, and sometimes through the original system. The September and October dry season pushes fine dust, pollen, and wildfire smoke ash from the Santa Cruz Mountains into attics and return plenums. Homeowners who burned through filter changes after a smoke event often discover the real issue is a disconnected return pulling attic air directly into the conditioned space. In the 94022 and 94024 tracts especially, original duct runs are often buried under blown-in insulation, with later add-on flex spliced in and sometimes crushed by storage or by the insulation itself. A cleaning call in Los Altos is frequently a repair call in disguise.

Our Main Los Altos Services
Most Los Altos homeowners call us for one of two problems: ducts that have never been seriously cleaned, or dryer vents that have never been inspected. Both are full services here, not add-ons.
Air Duct Cleaning in Los Altos
We run Rotobrush contact-cleaning tools through every accessible run, paired with Nikro HEPA negative-air machines to keep dislodged debris from drifting back into living spaces. In Los Altos that matters because attic dust here is fine, abundant, and often carries wildfire smoke residue. Homes in 94040 and 94023 with original rigid metal and later flex add-ons need the system mapped before cleaning starts, otherwise you’re vacuuming blind. We document with before-and-after photos of your own ducts, not stock images. See Air Duct Cleaning in Los Altos for pricing and process details.
Dryer Vent Cleaning in Los Altos
Los Altos laundry rooms are often in interior hallways or garages, which means long, multi-elbow dryer vent runs through crawlspaces and walls. Lint accumulates at every bend. Dryer vent fires are preventable, and this is a dedicated fire-prevention service using Abatement Technologies containment equipment, not a quick vacuum pass. We inspect the full run, clean it to bare metal, and verify airflow at the termination point. See Dryer Vent Cleaning in Los Altos for the full scope and schedule.
Air Duct Repair in Los Altos
Air duct repair in Los Altos almost always starts with a home addition. A homeowner adds square footage, the contractor ties new flex duct into the original 1960s sheet-metal trunk, and nobody checks whether the old system can handle the new load. Ten or fifteen years later, the master bedroom is ten degrees off from the kitchen and the return is pulling attic air. Our repair work on Los Altos homes is as much about diagnosing the patchwork as it is about sealing or replacing it. We trace every run we can access, measure static pressure, find the disconnects and crushed sections, and then fix what’s actually wrong, not what’s easiest to bill. That’s the full-scope approach behind Air Duct Repair as a standalone service, not a footnote to a cleaning job.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat setting, whistling or rushing air noise from supply registers, or visible dust streaks around return grilles usually point to a damaged or disconnected duct run.
What it costs in Los Altos
Ductwork repair in Los Altos typically runs $180 to $480 per section depending on access, with attic work in low-clearance 1950s and 1960s ranches trending toward the higher end.
How we do it
We locate the damaged or disconnected section, seal or reconnect it with code-compliant materials and mastic, then verify airflow and temperature at the affected registers.
Air Duct Replacement
Signs you need it
Original 1950s and 1960s rigid duct that’s rusted through, crushed flat under insulation and storage, or too corroded to seal is a replacement candidate, not a repair candidate.
What it costs in Los Altos
Air duct replacement in Los Altos ranges from $2,500 to $6,800 depending on home size and how much of the system runs through low-pitch attic spaces, with crawlspace returns adding labor.
How we do it
We remove the failed sections, install new duct matched to the existing system, seal every connection with mastic, and rebalance airflow so all rooms receive conditioned air evenly.
What Air Duct Repair Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| Ductwork repair (per section) | $180 – $480 |

How long does air duct repair take in Los Altos?
Most repairs finish in a single half-day visit. Whole-system replacement in a larger renovated ranch can span two days. We’ll confirm the timeline before work starts.
Do I need a permit for duct repair in Los Altos?
Simple repairs and reconnections do not require a permit. Full-system replacement may trigger a mechanical permit. We’ll tell you exactly what applies before we start. Call (833) 620-7085 for a straight answer on your situation.
Brands We Service in Los Altos
We work with Honeywell and Aprilaire filtration products daily, and install them as part of a duct repair or cleaning when the existing filtration isn’t doing the job. Most common Honeywell media filters and Aprilaire replacement filters are stocked on our trucks, so a filter upgrade during a Los Altos service visit doesn’t mean a second appointment. See our brands for the full list.

FAQs About Air Duct Cleaning Company in Los Altos
Most Los Altos appointments are scheduled within three to five business days. If a smoke event or a disconnected duct has pushed air quality to the point where you’re worried, mention it when you call and we’ll do what we can to shorten the wait. Call (833) 620-7085.
Interior ductwork and dryer vent work are inside the home and don’t require HOA approval. Only exterior work like a new roof termination or visible vent cap on a street-facing elevation might need a quick check with your HOA, and we’ll flag that before any work starts.
Yes. We serve 94040, 94022, 94023, and 94024, including the unincorporated edges near the hills. Our crews know the difference between a downtown-era original system and a hillside custom rebuild, and we bring the same equipment to both.

What Los Altos Customers Say
"Honest people. That's getting rare."
- Scott Rhodes"Our tenant called us in a panic on a Friday afternoon, which is the worst possible timing for a property 200 miles away. I called these guys at four, they were on site by six, and they sent me photos and a written summary the same night so I could approve the work without driving down. Tenant said the technician was polite and cleaned up. Invoice came in slightly under the estimate. I have now made them our default for anything in that area."
- Tim Miller"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
