Air Duct Cleaning Company in Sunnyvale, CA
Air duct cleaning in Sunnyvale costs most homeowners between $450 and $900 for a whole-house system, depending on home size, number of returns, and how long it’s been since the last cleaning. We’re Kestrel Air Duct Cleaning, and we work across Sunnyvale’s postwar ranchers, Eichlers, and newer two-story builds where retrofitted HVAC and unconditioned attics create very specific dust problems. Our crews show up with a written price in your hands before any work begins, and every job carries the 365-Day Done Right Promise in writing. Call (669) 220-7869 for a free estimate.
Why Sunnyvale Homes Are Different
Sunnyvale’s housing stock skews heavily toward the postwar boom, and that changes what we find inside ductwork. The city has a high concentration of Eichler-style homes that originally shipped with radiant heating and no central AC. Over the decades, owners added forced-air systems, and many of those retrofits used undersized flex ducts squeezed through shallow crawl spaces. Those cramped spaces make access harder, and they’re often unsealed at the joints, which means the system pulls air from wherever it can get it.
The climate does the rest. Sunnyvale’s Mediterranean pattern – warm, dry summers and cool, wet winters – produces fine, powdery dust in the dry months and mold-promoting moisture in the wet ones. Homes near the bay get extra humidity from marine air, which can turn dust into a paste inside ducts. We regularly see original single-return systems in 1950s and 60s ranchers that have spent decades ingesting fine clay dust blown in from the Santa Cruz Mountains’ summer-dry soils. That dust settles in the trunk line and returns, then recirculates every time the blower kicks on. For allergy sufferers in Sunnyvale, cleaning that accumulated material out is often the single biggest indoor-air improvement they can make.
Styles & brands we work with




Our Main Sunnyvale Services
Sunnyvale homeowners call us most often for two things: cleaning the ducts that move heated and cooled air through the house, and clearing the dryer vent that pushes lint outside. Each has its own dedicated Sunnyvale page with local pricing and specifics.
Air Duct Cleaning in Sunnyvale
Sunnyvale’s mix of original duct runs and retrofitted HVAC means we encounter everything from 60-year-old galvanized trunk lines to brand-new flex duct that was poorly sealed at installation. We run a Rotobrush rotary system through the ducts to dislodge debris at the duct wall, then a Nikro negative-pressure unit pulls the loosened material out while Abatement Technologies HEPA filtration keeps it from re-entering your living space. In homes with unconditioned attics, we often find fiberglass insulation and attic dust that got pulled in through gaps. The full scope, pricing, and what to expect are on the Air Duct Cleaning in Sunnyvale page.

Dryer Vent Cleaning in Sunnyvale
A clogged dryer vent in Sunnyvale isn’t just slow-drying laundry – it’s a fire hazard that gets worse in older homes where the vent run is long, bends several times, or terminates through the roof. We clear the full run from the dryer connection to the exterior termination point, removing the compacted lint that a standard lint trap never catches. Many Sunnyvale homes have vent runs that pass through tight attic or crawl spaces, making professional equipment essential. See the Dryer Vent Cleaning in Sunnyvale page for pricing and what the job covers.

What pushes price up in Sunnyvale is access. Eichler and rancher crawl spaces are famously shallow, and when a technician has to belly-crawl 40 feet to reach a duct trunk, that time shows up on the quote. Homes with multiple returns or duct runs in unconditioned attics also take longer. Whatever the number, you’ll have it in writing before we touch a single vent – no per-vent add-ons, no door-step revisions, no surprises.

What Sunnyvale Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
