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.

Why Kestrel Air Duct Cleaning Is Walnut Creek’s Preferred Air Duct Cleaning Company
We’ve been serving Walnut Creek under the Kingswell Guarantee since 2004, and our reputation here was built one job at a time, one written promise at a time. Our technicians are background-checked, uniformed, and trained specifically on the access protocols that Walnut Creek’s older communities require. Walnut Creek homeowners call us back because we show up in the window we gave, we put the price in writing before touching a single vent, and we leave the job site cleaner than we found it. That’s The Kingswell Way, and it’s how we’ve operated from day one.
Our crews live with the same Diablo Valley heat you do. We understand why a neglected air handler in May becomes an emergency in August. And we’re registered with Rossmoor’s contractor access program, so we don’t waste your morning sitting at a gate we can’t open.
Residential Air Duct Cleaning in Walnut Creek
Residential Air Duct Cleaning in Walnut Creek means dealing with decades of accumulated debris in systems that were never designed for today’s constant AC use. Most Walnut Creek homes we service fall in the $350-$650 range for a full system clean, though older ranch homes with crawl-space access issues or Rossmoor units with damaged duct board can run higher when sealing work is needed. We don’t quote per-vent pricing. We price the whole system, put it in writing, and that’s what you pay.
Our process starts with a video inspection. We feed a camera through your supply and return lines so you see what we see: crushed fiberglass runs, disconnected joints, or a blower motor caked with debris that’s just going to blow back into clean ducts. Then we use Rotobrush rotary brush systems to agitate debris off the duct walls, Nikro negative-pressure units to pull it out of your home entirely, and Abatement Technologies HEPA filtration so nothing escapes into your living space during the work.
What We Find in Older Ranch Homes
The 1950s-1970s ranch homes in Northgate, Lakewood, and along Ygnacio Valley Road often have original rigid fiberglass duct board that turns brittle with age. We’ve pulled out sections that crumble at the touch, shedding fibers into the airflow. Low-clearance crawl spaces make this work harder. Our techs know how to maneuver professional agitation tools in tight quarters where a shop vac on a hose simply can’t reach.
Rossmoor’s Unique Challenges
Rossmoor’s roughly 6,700 units represent one of the largest concentrations of aging ductwork in California. Most were built in the 1960s and 1970s with fiberglass duct board that has now had 50-60 years to deteriorate. Contractors must pre-register, obtain a gate pass, and work within specific time windows. We know this process. We’ve done the paperwork. Our techs don’t get turned away at the gate.
Commercial Air Duct Cleaning in Walnut Creek
Commercial Air Duct Cleaning in Walnut Creek covers office buildings, retail spaces, medical offices, and multi-unit properties from downtown near Broadway Plaza to the business parks along Interstate 680. Typical commercial jobs run $800-$2,400 depending on system size and access, with larger facilities or those requiring after-hours work quoted individually. We put every commercial price in writing before work begins, with no exceptions.
Walnut Creek’s commercial buildings face the same Diablo Valley heat load as residences, but with longer run times and more complex zoned systems. Dust accumulation in commercial return ducts happens faster than most property managers expect, especially in buildings with high foot traffic or near construction zones. Our Nikro negative-air extraction systems handle high-volume commercial jobs without shutting down your HVAC system for extended periods.
Minimizing Business Disruption
We schedule commercial work around your operations, including early mornings and weekends. Our crews work with building engineers to isolate zones so cleaned sections stay clean while we move through the system. We document everything with before-and-after video so your maintenance records are complete.
Post-Construction and Remodel Cleaning
Walnut Creek’s active commercial renovation market means we regularly clean systems filled with drywall dust, insulation particles, and construction debris. Standard cleaning won’t touch this material. We use aggressive brush agitation followed by high-volume negative-air extraction to remove settled construction waste that would otherwise circulate for years.
Trusted Brands We Service in Walnut Creek
We clean ductwork connected to every major HVAC brand, and we stock Honeywell and Aprilaire filtration products for Walnut Creek homeowners who want to maintain clean air between service visits. Our technicians carry replacement media for common Honeywell electronic air cleaners and Aprilaire whole-house filters on every truck, so most filter upgrades happen same-visit without a return trip. For properties with ongoing air quality concerns, we also install Guardsman filtration upgrades and can spec Abatement Technologies portable HEPA units for temporary use during wildfire smoke events. Everything goes on the written estimate before we start.
Common Air Duct Cleaning Problems We See in Walnut Creek Homes
- Brittle fiberglass duct board shedding fibers. In Rossmoor’s 1960s-70s units and ranch homes throughout Northgate, the original fiberglass duct board has become fragile with age. Cleaning without inspection can make this worse. We camera-inspect first, then seal or replace damaged sections before agitation.
- Crushed or disconnected crawl-space runs. Low-clearance crawl spaces in slab-on-grade homes off Ygnacio Valley Road hide duct damage that homeowners never see. Our video inspection catches crushed runs that restrict airflow and harbor mold. Cleaning alone won’t fix these. We quote sealing work separately, in writing.
- Smoke particulate accumulation from wildfire events. The 2018 Camp Fire blanketed Walnut Creek for weeks, and smaller fires recur almost annually. Fine particulates lodge in duct board and insulation. Standard cleaning without HEPA containment and source removal just redistributes them. We use Abatement Technologies HEPA filtration during post-smoke jobs.
- Neglected air handlers re-contaminating clean ducts. Diablo Valley’s May-October heat cycle pushes AC systems hard. A blower motor caked with dust or a clogged evaporator coil will foul freshly cleaned ducts within weeks. We inspect the air handler during every full-system clean and flag maintenance that should happen first.
Pricing for Air Duct Cleaning in Walnut Creek, CA
Most residential air duct cleaning in Walnut Creek runs $350-$650 for a complete system, including supply ducts, return ducts, and the main trunk lines. Commercial systems start at $800 and range up to $2,400 for larger or multi-zone buildings. Rossmoor units and older ranch homes with damaged duct board may need additional sealing work, typically $150-$400 beyond the base clean, quoted only after camera inspection.
What drives cost: system size, number of trunk lines, crawl-space or attic access difficulty, and whether we find damaged ductwork that needs sealing. We do not price per vent. One flat price per system, agreed in writing, before any work begins. No doorstep revisions. No coupon prices that balloon once the truck is parked.

FAQs About Air Duct Cleaning in Walnut Creek
Yes. Rossmoor requires outside contractors to pre-register, obtain a gate pass, and work within specific time windows. Our technicians are already in Rossmoor’s contractor access program, so we handle the paperwork and arrive when we’re supposed to. Call (469) 972-3151 to schedule, and we’ll confirm your unit’s access requirements when we book.
Original fiberglass duct board that has turned brittle after 50-70 years, often with crushed or disconnected sections in low-clearance crawl spaces. We camera-inspect every older Walnut Creek home before cleaning, because agitating damaged duct board without sealing it first just spreads more fibers into your air. If we find damage, we quote sealing work in writing before proceeding.
Not always. Standard cleaning without HEPA containment can redistribute fine smoke particulates rather than remove them. We use Abatement Technologies HEPA filtration during post-smoke jobs, and we inspect your system’s insulation and filter media, which often need replacement after heavy smoke exposure. For severe events, we may recommend a full source-removal clean plus upgraded filtration.
Walnut Creek’s inland Diablo Valley location means hotter summers, heavier AC use, and more wildfire smoke exposure than coastal Bay Area cities. The city also has an extraordinary concentration of 1960s-1970s housing, especially in Rossmoor, with aging fiberglass duct systems that coastal cities simply don’t have at this scale. Our methods and pricing reflect these real local conditions.
Yes. We service office buildings, retail spaces, medical offices, and multi-unit properties throughout Walnut Creek, from downtown to the I-680 corridor.
