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.
Fast, Reliable Air Duct Cleaning Across Walnut Creek
Air duct cleaning in Walnut Creek typically costs $450-$950 for a full system on a single-family home, and the job takes four to seven hours depending on the number of ducts and how much debris has built up inside them. That’s the honest range. What matters more than the number is what you get for it: a written price before work starts, a camera inspection that shows what’s actually inside your ductwork, and a before-and-after photo record so you can see the work with your own eyes. Our crews know Walnut Creek’s housing stock inside out, from the 1970s ranches in Northgate to the patio homes in Rossmoor, and we quote every job the same way: one flat price per system, in writing, before a single panel comes off.

Why CleanRun Air Duct Cleaning Is Walnut Creek’s Preferred Air Duct Cleaning Company
We make one promise that changes how the whole job goes: you get a written price before any work begins. That’s Haven Standard Clause 1, and it’s the same on every job, every time, no exceptions. The industry’s standard move is a low teaser price that becomes a much larger invoice once the technician is standing in your living room. We go the other direction. Tomas Reyes, who leads our team, built CleanRun in 2013 on the idea that a duct cleaning company should show its work, not just talk about it.
Every visit to a Walnut Creek home concludes with a Documented Photo Record of every duct run, photographed before and after. That’s not a selling point; it’s a deliverable. You’ll see the same camera footage our technician sees, whether it’s sediment packed into a return drop in Saranap or a fiberglass-lined run in Rossmoor that’s shedding fibers into the airstream. Our Air Duct Cleaning crews are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3. And every job is backed by the 365-Day Done Right Promise: if it’s not right, we make it right, in writing.
Our Air Duct Cleaning Services in Walnut Creek

Residential Duct Cleaning
Most Walnut Creek homes we service were built between the late 1960s and mid-1970s, and many still carry their original duct systems. That’s decades of accumulated particulate: Mount Diablo foothill dust, pet dander, skin cells, and the fine gray film that Diablo winds push into every crack in the building envelope. We run negative-pressure extraction through the entire system after mechanically agitating the interior surfaces, pulling debris out of the plenum, supply runs, return runs, and registers. The result is a documented reduction in the particulate load your HVAC system circulates every time the blower kicks on.

Commercial Duct Cleaning
Walnut Creek’s office buildings and medical suites along North Main Street and Ygnacio Valley Road run their air handlers all year, not just in summer, because commercial occupancy is constant. That means more particulate cycles through the ductwork than a home ever sees. We schedule commercial work around your operating hours, provide a written scope before mobilizing, and deliver the same photo documentation to facilities managers that homeowners get. A clean supply run means fewer complaints from employees and tenants about dust buildup on desks and equipment.

Supply Duct Cleaning
Supply ducts carry conditioned air from the air handler to each room, and in Walnut Creek they take the brunt of Diablo wind particulate. When our techs inspect supply runs in Tice Valley homes, they routinely find fine gray dust and soil particles that settled out of the airstream at elbows and transitions. We clean every supply run individually, using rotating agitation tools sized to the duct, with the system under negative pressure so loosened debris is pulled out rather than pushed into the room.

Return Duct Cleaning
Return ducts pull air back to the air handler, which means they also pull in whatever’s floating around your home: cooking oils, candle soot, dust from window screens during the dry fall months when every Walnut Creek house opens up to the evening air. The tacky film we find in returns, especially in Rossmoor homes where the original fiberglass lining has begun to break down, can’t be removed by a shop vacuum. Source removal means physically dislodging that film and extracting it, not fogging it with a deodorizer and calling it done.

AfterTrusted Brands We Service in Walnut Creek
We run professional-grade equipment from brands you can verify independently: Rotobrush for mechanical agitation, Nikro and Abatement Technologies for HEPA-filtered negative-air systems, and Guardsman for sanitizing where the scope calls for it. Because Walnut Creek is so widely known for its late-1960s and early-1970s construction, our trucks stock the materials our techs need most on local jobs: replacement mastic, foil tape rated for ductwork, and filter media sized to common local air handlers. That means fewer trips back to the shop and a faster start-to-finish time for you.
Common Air Duct Cleaning Problems We See in Walnut Creek Homes

- Diablo wind particulate loading: Walnut Creek sits in an inland valley directly in the path of hot, dry offshore winds that funnel through breaks in the coastal range, carrying Mount Diablo foothill dust and fine wildfire ash into HVAC systems at rates coastal Bay Area cities never experience. The dust coats duct interiors, then bakes on when the AC cycles.
- Rossmoor’s original ductwork with asbestos risk: Rossmoor’s roughly 6,700+ homes were built in a tight window from the late 1960s into the early 1970s, and many still run original fiberglass-lined or flex ductwork. The joint tape used in that era often field-tests positive or presumptive for asbestos, which means a material assessment belongs in the quote before any cleaning begins.
- Collapsed flex duct in Northgate and Tice Valley ranches: The suburban ranches in these neighborhoods were built at a time when duct design was simpler and flex duct was cheap. With decades of heat cycling and summer lows that push the AC hard, that flex can tear or collapse, restricting airflow and pulling attic air with insulation fibers into the supply stream. A camera inspection finds it before cleaning does.
- Condensation and microbial growth from summer humidity: Walnut Creek’s summer heat means the AC runs constantly for months, and the temperature difference between the cool air inside supply ducts and the attic air outside them creates condensation. That moisture, combined with Diablo wind dust, forms a tacky film inside duct runs that becomes a breeding ground for microbial growth. Cleaning removes the growth; fogging just covers the smell.
Pricing for Air Duct Cleaning in Walnut Creek, CA
A full Air Duct Cleaning in Walnut Creek runs $450-$950 for a single-family home, depending on the number of runs and the condition of the ductwork. Condos and patio homes, especially in Rossmoor, fall on the lower end of that range when the system is compact, but the material assessment for asbestos on original 1960s and 1970s tape adds $150-$300 to the quote when it’s required. We show you the written number before any work starts, and that’s the number you pay. One flat price per system, not per vent. A competitor quoted you $79?

FAQs - Air Duct Cleaning in Walnut Creek

Yes. Your filter protects the air handler, not the ductwork beyond it. Changing the filter prevents large particles from entering the blower and coil, but it does nothing for the fine dust that’s already made it past the filter and settled into the supply and return runs along the way. Walnut Creek’s persistent Diablo wind particulate is fine enough to pass through most standard filters, and it accumulates inside duct runs where the filter never reaches.
Call (806) 606-6902 if you want a camera inspection to see what’s actually in there, no obligation.
Walnut Creek’s summer temperatures regularly exceed 100°F, 15 to 25 degrees hotter than coastal Oakland, which means central air runs harder and longer. That constant temperature differential between the cooled air inside the ducts and the hot attic air outside creates more condensation, and condensation combined with Diablo wind dust creates the tacky film that supports microbial growth. Coastal Oakland simply doesn’t cycle the same volume of hot, dry, particulate-laden air through residential systems.
Most of the time, yes. Rossmoor’s roughly 6,700+ homes were built between the late 1960s and early 1970s, and the duct joint tape used in that era frequently tests positive or presumptive for asbestos. Cleaning a system with asbestos-containing tape can disturb the material and release fibers into the airstream. Our crews quote a material assessment into any Rossmoor bid before touching the system, because a standard cleaning quote that ignores that risk is a mistake waiting to happen.
Call (806) 606-6902 and we’ll tell you straight whether your system needs an assessment before we clean.
No. Fogging sprays a deodorizer or antimicrobial mist into the ductwork, which can mask the smell of the microbial growth for a few weeks but does not remove the underlying layer of fine particulate and organic film that supports it. A full cleaning with mechanical agitation and HEPA filtration removes the film and the particulate; fogging just covers the symptom. If a company offers you a fogging treatment instead of source removal, ask them what exactly they’re doing about the debris that’s still in the duct.
Every three to five years is typical for most Walnut Creek homes, but the spread depends on location and housing type. Homes in the path of Diablo winds accumulate particulate faster and may need cleaning on the shorter end of that range. Rossmoor homes with original fiberglass-lined ducts and the associated condensation and asbestos considerations should be inspected sooner rather than later, because the longer you wait on original ductwork, the more expensive the eventual repair or replacement becomes.
Call (806) 606-6902 for an honest assessment of whether your system needs it now or can wait.
