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 Atherton, CA
Atherton’s ductwork rarely fails quietly. In 5,000 to 15,000 square foot estates with long multi-zone runs above vaulted ceilings, a small separation at a joint, a crushed flex run, or a disconnected return pulls attic air and years of accumulated debris into living space. That’s where Air Duct Repair becomes the urgent call, not an afterthought. We’re Air Duct Cleaning Palo Alto, and we’ve served Atherton since 2016 with the same professional-grade equipment used in commercial restoration work. Call (833) 620-7085 when you need a real fix, not a patch.
Why Atherton Homes Are Different
Atherton’s 94027 ZIP is dense with mature redwood, oak, and eucalyptus canopy. That tree cover shades the private lanes off Middlefield and Valparaiso, but it also sheds needles and fine leaf litter year-round. On estate systems, exterior return grilles and intake screens load with organic debris faster than any sun-exposed subdivision, which means the air stream carries more particulate into the ductwork itself. Winter moisture adds another layer: damp debris inside exterior returns creates the exact conditions where mold spores take hold.
The housing stock compounds this. Most Atherton homes are custom builds or major rebuilds from the 1980s through the 2000s, with forced-air systems running two, three, or even four zones. Duct runs are long, concealed in attic chases and above hard-to-access ceilings. Some older pre-rebuild pockets still have original galvanized runs mixed with early flex duct. A cleaning that ignores the condition of those runs is half a job. Repair and cleaning have to be scoped together.

Our Main Atherton Services
Two services account for most of the calls we take from Atherton homeowners and property managers: full-system air duct cleaning for houses where the canopy keeps loading the returns, and dryer vent cleaning where lint accumulation is a fire risk, not a chore.
Air Duct Cleaning in Atherton
Estate systems hold more debris than their square footage suggests. Long runs, multiple zones, and year-round canopy loading mean compacted dust and organic material settle deep in trunk lines and branch runs. We clean with Rotobrush contact-cleaning systems and run Nikro HEPA negative-air machines to capture what the brushes dislodge, so the debris we remove doesn’t recirculate through bedrooms and kitchens. For the full scope of this service in Atherton, see Air Duct Cleaning in Atherton.

Dryer Vent Cleaning in Atherton
Lint is fuel, and Atherton’s long dryer vent runs through concealed chases give that fuel a long path to accumulate. We treat dryer vent cleaning as a fire-prevention service: full-length mechanical agitation, HEPA-filtered capture at the termination point, and verification of airflow before we leave. No upsell, no shortcut. See Dryer Vent Cleaning in Atherton for how this works on Atherton estate homes.

Air Duct Repair in Atherton
Duct problems in Atherton tend to be hidden by the house itself. The 1980s-to-2000s rebuilds have duct runs above vaulted ceilings and through attic chases where a crushed flex section or separated joint goes unnoticed for years, pulling attic air and fine insulation into the conditioned space. Older pre-rebuild pockets still mix original galvanized trunk lines with early flex branches, and that combination fails at the transitions. When a zone stops responding or a room won’t hold temperature, the fix is usually in the duct run, not the equipment. That’s the work we do under Air Duct Repair, and it’s why Atherton homeowners call us instead of a cleaner who won’t touch the duct itself.
Ductwork Repair
Signs you need it
Rooms that never reach setpoint, visible dust accumulating around supply registers, or a jump in heating and cooling costs point to leaks, separations, or crushed sections in the duct run.
What it costs in Atherton
Ductwork repair in Atherton typically runs $180 to $480 for a single leaking joint or crushed flex section, with more extensive repair across multiple zones pushing toward $1,200 to $2,400.
How we do it
We pressure-test or camera-scope the affected run, locate the exact failure, then seal with mastic and aluminum tape or replace the damaged section and verify airflow at the register.
Air Duct Replacement
Signs you need it
Original galvanized trunk lines from pre-rebuild homes that have rusted through, early flex duct that has collapsed or torn, or runs contaminated beyond what cleaning can remove should be replaced outright.
What it costs in Atherton
Air duct replacement in Atherton runs anywhere from $95 to $210 per new supply duct for a straightforward flex run, up to several thousand dollars when trunk lines and multiple zones are involved.
How we do it
We map the existing runs, remove the failed duct, install new rigid or flex to code, seal every joint, and rebalance the zone before verifying static pressure and airflow.
HVAC Duct Installation
Signs you need it
Additions, remodels, or secondary systems where no duct exists yet, or where a renovation has left rooms cut off from the existing zoned layout, call for new duct installation.
What it costs in Atherton
New HVAC duct installation in Atherton typically ranges from $95 to $210 per supply run for basic flex installation, with rigid duct and complex multi-zone layout pushing project cost higher.
How we do it
We size the run, install the new duct, seal and insulate as required, connect to the air handler, and confirm the zone balances with the rest of the system.
What Air Duct Repair Costs in Atherton
| Item | Typical range in Atherton |
|---|---|
| Ductwork repair (single joint or short flex section) | $180 – $480 |
| Air duct replacement (per new supply duct) | $95 – $210 |
| HVAC duct installation (per new supply run) | $95 – $210 |
Can you repair just one section of ductwork, or does the whole run need replacing?
Most Atherton repairs are isolated. A crushed flex branch or separated joint can be fixed without touching the rest of the zone. If the trunk line itself is rusted or contaminated, replacement makes more sense. Call (833) 620-7085 for an honest scope.
How long does duct repair take in an estate home?
Most single-section repairs finish the same day, even where access means working through an attic chase. Full replacement of multi-zone runs can take two to three days depending on access and finish protection. Call (833) 620-7085 for a time estimate on your system.
Brands We Service in Atherton

In Atherton, two things push cost: access and zone count. A four-zone estate system above vaulted ceilings takes longer to map, clean, and protect than a single-zone ranch. We quote one flat price per system before work starts, with no per-vent pricing and no add-ons after the fact.

What Atherton Customers Say
"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."
- Daniela Hernandez"Told me straight that our ducts were in decent shape and didn't need doing every year like the mailer companies claim."
- Gilbert Garcia"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
