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.

AfterFast, Reliable Air Duct Cleaning Across Cupertino
Air duct cleaning in Cupertino typically runs $350 – $650 for a full residential system, with most jobs scheduled within a few business days and completed in a single visit. We’re the Air Duct Cleaning crew that knows what we’re walking into here: decades-old galvanized steel ductwork, original asbestos wrap from the 1960s, and the accumulated dust of half a century’s Silicon Valley summers. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but our technicians live and work in this corridor, so we’re not driving down from Sacramento or up from Fresno. When you call (361) 326-5060, a live person answers, and we’ll give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Cupertino’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our standard hasn’t changed: arrive inside the quoted window, price it in writing, do it by the book, leave the site clean. That’s The Garrison Standard, and it applies to every Cupertino job we take.
Our technicians are background-checked and uniformed. You know who’s coming before they walk through your door. And every repair and cleaning we perform is backed by our 365-Day Done Right Promise – if the work fails within a year, we return and make it right at no charge, including a free second visit. No negotiation, no runaround.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. Cupertino homeowners have been burned by no-shows and price jumps; we fix that with operational specifics, not adjectives.
Air Duct Repair in Cupertino
Air Duct Repair in Cupertino is rarely about a single broken piece. In the 1950s – 1970s ranch tracts that dominate this city, we find disconnected branch runs, crushed returns near the air handler, and original galvanized steel that has separated at the joints after sixty years of thermal cycling. A homeowner might call for a cleaning, but our camera inspection often reveals the real problem: the ducts aren’t dirty, they’re broken.
What We Find in Older Cupertino Attics
Low-pitch roofs and tight crawl spaces are standard in Cupertino’s ranch homes. Our video inspection locates disconnected runs that have been blowing conditioned air into the attic for years, and crushed flex lines where someone stepped through a joist bay during a re-roof. We document everything with before-and-after photos of your own ducts, not stock images.
Repair vs. Replacement
Sometimes the honest answer is that sealing beats repairing. Where original joints have opened up, mastic duct sealing creates a permanent fix that cleaning alone can’t match. We price both options in writing before any work starts, so you decide with real numbers, not pressure.
Ductwork Cleaning in Cupertino
Ductwork Cleaning in Cupertino means something different than in a 2019 subdivision. Here, we’re often restoring half-century-old systems that have never been cleaned, with layers of dust compounded by oak pollen, construction debris from multiple renovations, and the fine particulate that drifts through Silicon Valley’s dry summers. Our process adapts to what your system actually is, not what a generic checklist assumes.
Negative-Air Source Removal
We use Nikro negative-air machines to establish controlled suction at the main trunk, then deploy Rotobrush rotary brush systems through each branch line. This pulls debris toward the collection unit rather than pushing it into your living space. In Cupertino’s older homes, we take extra care with fragile original fittings that newer equipment might damage.
The Asbestos Wrap Protocol
Because so many Cupertino tracts were built during the 1950s – 1970s aerospace boom, a routine duct cleaning call here regularly turns into an asbestos-abatement-triggered job: the original galvanized runs are wrapped in deteriorating 1960s insulation that must be tested and handled per Bay Area Air Quality Management District rules before any cleaning begins – a step rarely needed in newer nearby Sunnyvale or Santa Clara homes. We coordinate this testing as part of our standard intake; it’s not an upsell, it’s a legal and safety requirement.
Trusted Brands We Service in Cupertino
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use in Bay Area office parks and medical facilities, not hardware-store attachments. For Cupertino homeowners, that means the job gets done to a standard that matches the equipment: thorough, documented, and built to last. We stock common parts and materials locally, so if your cleaning reveals a repair need, we’re not ordering components from a warehouse two states away. The turnaround matters when you’re dealing with a system that’s already been limping along for decades.
Common Air Duct Cleaning Problems We See in Cupertino Homes
- Disconnected branch runs in original 1960s galvanized systems. In the ranch tracts off McClellan Road and around Rancho Rinconada, we regularly find branch lines that have separated from the main trunk, blowing heated or cooled air directly into the attic. Homeowners notice weak airflow and high energy bills; the fix is reconnection and sealing, not another cleaning.
- Crushed returns near the air handler. Low-pitch roofs and tight utility closets in Cupertino’s older homes mean the return path is often a flex duct that’s been compressed by storage items, water heater replacements, or simple age. Our camera inspection catches this before we quote any cleaning work.
- Asbestos-containing duct wrap from the 1960s. The original insulation on galvanized runs in Cupertino’s aerospace-era tracts frequently contains asbestos. Bay Area Air Quality Management District rules require testing and proper handling before any disturbance. We build this step into every older-home intake; skipping it is not an option.
- Eichler-style radiant-heat homes with no ductwork at all. Neighborhoods like Rancho Rinconada feature homes designed for radiant heating that lack conventional ducts entirely. A cleaning call here converts to a duct sealing or retrofit consultation, not a cleaning ticket. We tell you that upfront, not after we’ve driven out and set up equipment.
Pricing for Air Duct Cleaning in Cupertino, CA
A typical residential duct cleaning in Cupertino runs $350 – $650 for a full system, depending on the number of branch lines, the accessibility of the main trunk, and whether asbestos testing and wrap handling are required. Commercial systems start around $800 and scale with square footage and HVAC zoning. Duct repair work, when we find disconnected or crushed runs, typically adds $200 – $450 to the base cleaning price. Duct sealing with mastic, the long-term fix for opened joints, runs $400 – $900 for a whole-house application.
What affects your specific price: the age and material of your original ductwork, the presence of asbestos wrap requiring BAAQMD-compliant handling, the number of registers and returns, and whether we need to coordinate access to a tight attic or crawl space. We do not quote per-vent pricing, and we do not bait with a low teaser that jumps once the technician is inside. The price is written down before any work starts, and it does not move at the door. Call (361) 326-5060 for an exact quote – estimates are free.

FAQs About Air Duct Cleaning in Cupertino
Because the dominant housing stock here is 1950s – 1970s ranch homes with original galvanized steel ductwork that has never been cleaned and often has disconnected or crushed runs. Our camera inspection finds these failures before we remove any debris, and we quote the repair in writing alongside the cleaning. In Rancho Rinconada, a homeowner called about dust blowing from the registers in a 1962 ranch home with original galvanized steel ductwork and a 2015 HVAC replacement. Our camera inspection found two disconnected branch runs under the low-pitch roof and a crushed return near the air handler, and after clearance on the aged duct wrap, we pulled the debris under negative pressure with source removal and reconnected the runs. The dust complaints stopped, and we advised the homeowner that duct sealing, not another cleaning, was the real long-term fix where the original joints had opened up. Call (361) 326-5060 to schedule an inspection.
Yes, if your home was built during the 1950s – 1970s and has original ductwork with aged wrap insulation. Bay Area Air Quality Management District rules require testing and proper handling of asbestos-containing materials before any disturbance. We coordinate this testing as part of our standard intake for older Cupertino tracts; it’s built into our protocol, not sold as an add-on. Call (361) 326-5060 and we’ll verify whether your home falls under this requirement during scheduling.
No, because Eichler-influenced and standard radiant-heat homes in Rancho Rinconada typically have no ductwork at all. A cleaning call here converts to a duct sealing or retrofit consultation. We’ll tell you that during the phone intake, not after we’ve arrived with equipment. If you’re unsure what heating system you have, call (361) 326-5060 and we’ll sort it out before scheduling.
Every three to five years for most Cupertino homes, but annual cleaning makes sense if you have significant oak pollen exposure, have completed recent renovation work, or notice visible dust emission from registers. The dry summers and surrounding woodlands here produce more particulate load than coastal cities, so original systems accumulate debris faster than their owners expect. Call (361) 326-5060 to discuss your specific situation.
We start with a video inspection of the full system, then test any aged duct wrap for asbestos per BAAQMD rules. Once cleared, we establish negative-air containment with a Nikro unit, run Rotobrush rotary tools through each branch line, and collect all debris at the source. We photograph before and after conditions of your own ducts, reconnect any separated runs we find, and leave you with a written report and our 365-Day Done Right Promise. The process typically takes four to six hours for a standard ranch home. Call (361) 326-5060 to schedule.
