Air Duct Cleaning Company in Cupertino, CA
Air duct repair in Cupertino comes down to one recurring problem: homes built between 1955 and 1975 are still running their original galvanized ductwork, and after 50 to 70 years, that metal is rusting through at the seams, crushing under attic insulation, or pulling apart at the joints. We’re Duct Cleaning Mountain View, and we’ve served Cupertino since 2015. Most calls we get from 95014 and 94087 start as a cleaning request and end with us finding a disconnected return or a crushed trunk line the homeowner had no way to see. Call us at (866) 528-3938 and we’ll tell you what’s actually happening inside your ducts.
Why Cupertino Homes Are Different
Cupertino’s housing stock reads like a timeline of mid-century tract construction. The Eichler-style and ranch homes that dominate 95014 and 94087 were built fast, with horizontal attic duct runs and low-pitch roofs that leave little room to maneuver. Their original ducts were galvanized sheet metal, often wrapped in insulation that has since deteriorated into brittle, crumbling sleeves. When that wrap fails, the duct sweats in summer and loses conditioned air into the attic in winter. Homeowners don’t notice until the bedroom at the end of the hall stops cooling or the utility bill climbs without explanation.
Then there’s what sits on top of those ducts. Decades of blown-in cellulose and fiberglass have settled and compressed, and in many attics the ducts have sunk beneath the insulation rather than resting above it. When a run develops a gap at a joint or a tear in the flex section, the system pulls attic air directly into the supply side. That means the dust, fiberglass particles, and whatever else lives in the attic gets distributed through every register. We’ve pulled enough rodent nesting material out of Cupertino attic runs to know that a cleaning job here is never just a cleaning job. It’s an inspection of the whole run, because the duct itself is usually the source of what’s coming out of the vents.
Wildfire smoke adds a seasonal layer. Late summer and fall bring smoke from the Santa Cruz Mountains into Cupertino, and HVAC returns pull that particulate into the system. Homes that ran their air handlers during the 2020 SCU and CZU fire complexes still carry residue in their ducts unless they were cleaned afterward. Because Cupertino’s mild winters mean the system stays mostly off from November to April, dust and smoke residue accumulate longer between cleanings than they would in a city where the furnace runs all winter.

Our Main Cupertino Services
Cupertino homeowners call us about two things more than anything else: ducts that haven’t been cleaned in years, and dryer vents that are packed with lint in tight mid-century laundry closets. Both jobs are more involved here than in newer construction, for reasons tied directly to the housing stock.
Air Duct Cleaning in Cupertino
Cleaning ducts in a 1960s ranch is different from cleaning ducts in a 2005 townhome. The runs are longer, the metal is corroded in places, and the attic access is usually tight. We run our professional-grade Rotobrush and Nikro systems through the full supply and return runs, while Abatement Technologies HEPA filtration equipment captures what comes off the duct walls so it doesn’t recirculate into the living space. In Cupertino we always check for disconnected flex and crushed sections during the cleaning, because in these homes the two problems travel together. See the full scope on our Air Duct Cleaning in Cupertino page.
Dryer Vent Cleaning in Cupertino
Many Cupertino ranches have laundry rooms on interior walls, which means the dryer vent runs ten to twenty feet through the wall cavity or under the slab before it exits. Lint builds up in those long runs quickly, and a dryer that takes two cycles to dry a load is usually telling you the vent is restricted. We clean the full run from the dryer connection to the exterior termination, and we check for the crushed or kinked sections that are common in older homes. Details are on our Dryer Vent Cleaning in Cupertino page.
Air Duct Repair in Cupertino
Air duct repair in Cupertino usually begins with a homeowner who scheduled a cleaning and found out the ducts were compromised. In these 1955 – 1975 homes, the original galvanized runs have lived through five to seven decades of attic heat, insulation weight, and rodent traffic. Joints separate. Seams rust through. Flex sections kink or get chewed open. A cleaning alone can’t fix those problems, and in fact it can make a damaged run worse by loosening what little connection remained. That’s why we treat repair as its own service, not an add-on. We clean the duct, and we fix it if it’s broken. See the full scope on our Air Duct Repair page.
Ductwork Repair
Signs you need it
Rooms that stay warm in summer or cold in winter, visible dust buildup around specific registers, and unexplained spikes in your utility bill all point to a duct run that’s leaking or separated somewhere in the attic.
What it costs in Cupertino
Ductwork repair in Cupertino typically runs $180 – $550 depending on how many sections need to be reconnected, resealed, or patched and how difficult the attic access is.
How we do it
We locate the failed section by tracing each run from the plenum to the register, then we reconnect separated joints, seal gaps with mastic and metal tape, patch or replace damaged flex sections, and test the system pressure to confirm the repair.
Duct Replacement
Signs you need it
Ducts that have rusted through, collapsed under insulation weight, or been chewed open by rodents need replacement rather than patching, especially when multiple sections in the same run have failed.
What it costs in Cupertino
Duct replacement in Cupertino typically ranges from $1,100 to $2,900 depending on the length of the run, the number of sections being replaced, and whether the attic access requires cutting additional openings.
How we do it
We remove the failed duct sections, install new galvanized or flex duct matched to the existing system size, seal every connection with mastic, re-wrap insulation where needed, and balance airflow to the affected registers.
What Air Duct Repair Costs in Cupertino
| Item | Typical range in Cupertino |
|---|---|
| Ductwork Repair (single section) | $180 – $550 |
| Duct Replacement (full run) | $1,100 – $2,900 |
| Register, grille, or vent cover replacement | $30 – $80 per vent |
How do I know if my Cupertino home’s ducts need repair or just cleaning?
If dust reappears within days of cleaning, airflow is weak at specific registers no matter how you adjust the dampers, or you can see crushed or disconnected flex in the attic, those are repair indicators. Cleaning addresses what’s inside the duct. Repair addresses the duct itself. Call us for an assessment.
Can you repair ducts in Eichler homes without tearing into the ceiling?
Yes, in most cases. Eichler-style homes in Cupertino typically have attic-accessible duct runs with the supply registers in the ceiling plane. We work from the attic side whenever possible, which avoids cutting into finished surfaces. Where slab-embedded runs have failed, we’ll tell you plainly what access is required before any work starts.
Brands We Service in Cupertino
We work with Honeywell and Aprilaire air quality equipment in Cupertino homes, from replacement media filters to whole-home purification units. We keep common parts stocked, which shortens turnaround when a system already has Honeywell or Aprilaire components in place. See our full brands line.

- Carmen Delgado"Two guys, about three hours, plastic down at every register, and they wiped the vent covers before putting them back."
