Air Duct Cleaning Company in Los Altos, CA
Air duct repair in Los Altos usually means wrestling with sixty-year-old Eichler ductwork that was never designed for modern HVAC loads. We get called out to homes where original 1950s closet furnaces feed short plenum runs that real-estate inspectors have flagged, or where a later AC retrofit buried flex duct through a low-clearance crawlspace. Duct cleaning here is rarely just about dust. Call us at (877) 358-5491 when you want a specialist who understands what Los Altos homes actually have behind their registers.
Why Los Altos Homes Are Different
Los Altos is Eichler country, and that changes almost everything about how we approach ductwork. Those iconic mid-century homes off Foothill Expressway were built for radiant slab heat, not forced air. When central AC came along decades later, contractors routed flex duct through attics and crawlspaces that were never intended to house it. The result is a patchwork: original 1950s plenum ducts feeding into 1980s attic runs, with fiberglass liners that have been quietly shedding for thirty years.
The climate hides the problem. Mild, dry summers and cool winters mean HVAC systems don’t run hard enough to blow dust out. Instead, spring oak and grass pollen settles into those accessible runs and stays there through the entire season. Rodent activity in low-clearance crawlspaces adds another layer. Most Los Altos homeowners don’t notice anything until a renovation kicks debris into the system or a family member’s allergy complaint sends them looking for an answer.

Our Main Los Altos Services
Three services cover almost everything we do in Los Altos: cleaning the ducts, clearing and verifying dryer vents, and repairing or replacing the duct structure itself. Here are the two Los Altos homeowners call about most often.
Air Duct Cleaning in Los Altos
Our Air Duct Cleaning in Los Altos service starts with a camera inspection, because in Eichler-era retrofits there’s no reliable way to predict what’s inside a run without looking. We then run professional-grade Rotobrush and Nikro equipment through every accessible duct, capturing debris at the source rather than pushing it into the living space. Los Altos jobs often reveal surprising layers: construction dust from a 1980s addition, rodent nesting material in crawlspace runs, and old fiberglass insulation fragments. We’ll show you before-and-after photos of your own system.
Dryer Vent Cleaning in Los Altos
Dryer vent cleaning is a safety service, not an upsell. Los Altos laundry rooms are often tucked into the center of Eichler floor plans, which means vent runs travel long horizontal distances through walls or crawlspaces before reaching the exterior. Every bend collects lint, and a clogged vent forces your dryer to work harder while pushing combustible material into a confined space. Our Dryer Vent Cleaning in Los Altos service clears the full run and verifies airflow at the exterior termination with a digital meter.
Air Duct Repair in Los Altos
Air duct repair in Los Altos frequently comes down to correcting what previous retrofits got wrong. Homes built in the 1950s and 1960s around Foothill Expressway and the surrounding neighborhoods often have original closet furnaces feeding short plenum ducts that were adequate for radiant-era expectations but fall short once cooling was added. When a flex-duct retrofit from a later AC installation is involved, we find crushed runs, disconnected joints, and uninsulated sections in crawlspaces that trap moisture against the galvanized steel. Repairing these systems isn’t about patching; it’s about restoring balanced airflow to a structure that’s been modified piecemeal for decades. Duct Cleaning Milpitas has served Los Altos since 2018, and our Air Duct Repair work covers everything from sealing small leaks to replacing runs that have failed entirely.
Ductwork Repair
Signs you need it
Rooms that never reach the thermostat temperature, a sudden spike in one utility bill, or visible crushed or disconnected flex duct in a crawlspace.
What it costs in Los Altos
Ductwork repair in Los Altos typically runs $300 to $1,200 depending on how many leaks, tears, or disconnected joints we find.
How we do it
We camera-inspect the affected run, locate the exact point of failure, seal or reconnect using code-compliant materials, and verify the repair with an airflow reading.
Air Duct Replacement
Signs you need it
Ducts that have collapsed, rusted through, suffered rodent damage, or were installed with the wrong diameter for the airflow your system now demands.
What it costs in Los Altos
Air duct replacement in Los Altos typically ranges $1,500 to $4,800 for a partial system, with full-home replacement running higher based on accessibility.
How we do it
We remove the failed section, size the new run correctly for the airflow requirement, install it with proper support and insulation, and rebalance the system to confirm even delivery.
What Air Duct Repair Costs in Los Altos
| Item | Typical range in Los Altos |
|---|---|
| Ductwork repair (single leak or disconnected joint) | $300 – $1,200 |
| Air duct replacement (partial system) | $1,500 – $4,800 |
| Ductwork installation (new run to serve an addition) | $1,200 – $3,000 |
Access matters more than anything else in Los Altos. A repair we can reach from a walk-in crawlspace costs less than one that requires removing a section of the original Eichler closet furnace surround. We give you one flat price per repair before work begins, and we don’t discover surprise change orders halfway through the job.
How do I know if my Los Altos ducts need repair or cleaning?
If air flows weakly from some registers but strongly from others, you likely have a structural problem, not a dirt problem. Cleaning clears buildup; repair fixes leaks, disconnections, and collapsed sections. We’ll diagnose the difference with a camera inspection before recommending any work.
Will repairing ducts in a Los Altos crawlspace require cutting into the slab?
No. In slab-on-grade Eichler and ranch homes, we access from the crawlspace or attic side rather than cutting concrete. In a few retrofits, duct runs pass through closet utility shafts, and we’ll work through existing access panels wherever possible.

AfterPricing for Air Duct Cleaning Company in Los Altos, CA
Here are the typical whole-system ranges we quote in Los Altos. Our prices are flat per system, agreed before work starts, and never priced per vent.
| Service | Typical range in Los Altos |
|---|---|
| Air duct cleaning (whole home) | $470 – $650 |
| Air duct cleaning (condo or apartment) | $330 – $370 |
| Commercial air duct cleaning | $900 – $2,500+ |
| Dryer vent cleaning (yearly service for a typical single-family home) | $130 – $160 |
| Ductwork repair (single leak or disconnected joint) | $300 – $1,200 |
| Air duct replacement (partial system) | $1,500 – $4,800 |
| Ductwork installation (new run to serve an addition) | $1,200 – $3,000 |
| HVAC duct installation (full system, new construction or major remodel) | $3,000 – $7,500+ |
Two things push Los Altos prices toward the higher end of these ranges: crawlspace clearance and the age of the original ductwork. A home with a 24-inch crawlspace requires more time and care than one with a walk-in basement. Regardless of the number, we quote one flat price before work starts and we don’t revise it after we begin.

FAQs About Air Duct Cleaning Company in Los Altos
Most Los Altos jobs are scheduled within one to two weeks. If you’re closing on an Eichler and the inspector flagged a duct issue, call us early in the escrow period so we can coordinate with your timeline rather than rushing at the end.
Almost never. Duct cleaning, repair, and replacement inside your existing system don’t require permits in Los Altos. If you live in a neighborhood with an active HOA, they may require notice for any work that involves contractors on the property, but that’s a courtesy call, not a permit.
Yes. We cover all four Los Altos ZIP codes including 94024 and 94023, which cover portions of the hills and some overflow delivery routes. You’ll get the same flat-pricing guarantee regardless of which part of Los Altos you’re in.
That depends entirely on the condition of the duct structure. In Los Altos, we often find that older flex-duct retrofits have hidden disconnections or crushed sections that cleaning can’t fix. Our camera inspection will tell you which problems are dirt and which are structural before we quote anything.

What Los Altos Customers Say
"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."
- Hector Morales"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
- Michelle Gallagher"They photographed every return and supply before starting and sent me the file afterward. No upsell to a sanitizing treatment I didn't need."
