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.

AfterAir Duct Cleaning Company in Cupertino, CA
Air duct cleaning in Cupertino typically runs $350 – $650 for a standard single-family home, with most jobs completed in one morning or afternoon. We’re Hollis Air Duct Cleaning, and Cupertino’s mix of 1950s – 1970s ranch homes with original galvanized steel ductwork creates a specific set of challenges you won’t find in newer Bay Area cities. Our crews work here regularly, from the older tracts near Rancho Rinconada to the hillside streets off Stevens Canyon Road. If you’re ready to book, call us at (361) 326-5060.
Why Cupertino Homes Are Different
Cupertino’s housing stock was built fast during the aerospace boom, and most of those single-story ranch homes still have their original rigid metal ductwork. We’ve opened systems in neighborhoods like Monta Vista and Fairgrove where the ducts hadn’t been cleaned in forty-plus years. That age matters: the galvanized steel collects different debris patterns than modern flex duct, and in some tracts, the original ductwork is wrapped in asbestos insulation from the 1960s. Our technicians test for that before touching anything, following Bay Area Air Quality Management District rules. It’s a step we rarely need in Sunnyvale or Santa Clara.
The climate here compounds the problem. Cupertino’s Mediterranean pattern, cool wet winters and warm dry summers, means HVAC systems run year-round. The dry months pull dust and oak pollen through return vents, and the surrounding woodlands keep that supply steady. We’ve pulled significant debris from systems near McClellan Ranch Preserve that homeowners assumed were “fine” because the house felt comfortable. Comfort and cleanliness aren’t the same thing.
Then there’s the Eichler factor. Rancho Rinconada and pockets near Portal Park have radiant-heat homes with no ductwork at all. When those homeowners call for duct cleaning, we often end up discussing duct sealing or retrofit options instead. Knowing the local architecture saves everyone time.
Our Main Cupertino Services
Most Cupertino homeowners call us for one of three jobs. Each has its own page with full detail, but here’s what the work looks like in this market.
Air Duct Cleaning in Cupertino
We clean the full supply and return system with a Rotobrush rotary brush and, for heavier buildup, a Nikro negative-air machine that pulls debris out under controlled suction. In Cupertino’s older homes, we often find construction debris from the original 1960s build still sitting in trunk lines, plus decades of settled dust the previous owners never addressed. We photograph the before condition and show you the after. Air Duct Cleaning in Cupertino has full pricing and process detail.
Dryer Vent Cleaning in Cupertino
Dryer vent blockages are a genuine fire hazard, and Cupertino’s mature landscaping doesn’t help. Lint traps catch most debris, but fine particles escape and build up in the run to the exterior, especially when the vent termination sits under oak canopy cover. We clean the full run from dryer to wall cap, test airflow with an anemometer, and flag any flexible transition hose that should be replaced with rigid metal. Dryer Vent Cleaning in Cupertino covers what we find and what it costs.
Duct Sealing in Cupertino
Original Cupertino ductwork leaks. The mastic and tape from the 1960s has dried out, and metal seams have worked loose from decades of thermal cycling. We seal accessible joints with mastic rated for HVAC use, then pressure-test the system to verify improvement. For homes with asbestos-wrapped ducts, sealing is sometimes the safer alternative to disturbing the wrap. Duct Sealing in Cupertino explains when sealing beats replacement.

FAQs About Air Duct Cleaning Company in Cupertino
No permit is required for standard duct cleaning or dryer vent cleaning in Cupertino. If we encounter asbestos-wrapped ductwork and need to disturb it, we follow BAAQMD notification rules, but that’s handled as part of the job, not a separate permit you need to pull.
We usually book within a few business days, sometimes sooner. Calls are answered by a live person 24/7, so you can reach us evenings or weekends to find a slot that works. We don’t overbook; we arrive inside the window we quote.
We do, but the call often shifts scope. Eichlers in Rancho Rinconada and nearby areas use radiant heat, so there’s no duct system to clean. We’ll inspect what you have, explain honestly, and discuss whether duct sealing or a retrofit makes sense for your setup. No charge for the assessment.
