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.

Air duct cleaning in Danville runs $450-$900 for a typical single-family home, with multi-zone Blackhawk and Sycamore Valley properties falling between $650 and $1,400 depending on system complexity. Most jobs are completed in 4-8 hours, and you’ll receive a documented photo record of every duct run before and after the work.

We know Danville’s duct systems because we’ve worked inside them for years. The custom homes off Camino Tassajara, the 1980s tracts along Sycamore Valley Road, the gated communities near Blackhawk Plaza - each has its own failures we can predict before the camera goes in. Our Air Duct Cleaning crews schedule Danville jobs Monday through Saturday, and because our Bay Area office dispatches locally, we’re not juggling a multi-county route when your appointment lands.
Why CleanRun Air Duct Cleaning Is Danville’s Preferred Air Duct Cleaning Company
Danville homeowners tend to be thorough. They want to see what’s inside the ductwork before paying to have it cleaned. That expectation is the entire reason our process exists. Every Danville job starts with a camera inspection of the plenum, main trunk lines, and branch runs - the network of metal and flex ducts that carries conditioned air from your furnace to each register. We show you what we find. Then we quote a written price. Then we do the work. This is Haven Standard Clause 1: written price before any work starts. Not a policy subject to manager approval. It’s how we’ve operated since 2013, across more than 52,000 homes.
The photos we take aren’t a novelty. They’re the record. Inside a Sycamore Valley custom home last summer, our camera showed a 3-inch debris build-up at the first elbow of a return run - pet dander, construction dust from a 1990s renovation, and a layer of Diablo wind silt that had been accumulating for years. The homeowner saw the image on our tablet, and the scope of work made sense without explanation. That’s how we like it. The written photo record is included on every Danville job, standard, delivered to you before we leave the driveway.
Every Danville crew member is background-checked, uniformed, and identified by name before arrival. Tomas Reyes, who leads our Bay Area operations, personally reviews each Danville job file for completeness - the written scope, the before-and-after photo record, and the warranty documentation.
Our Air Duct Cleaning Services in Danville

Residential Duct Cleaning
Single-family homes in Danville make up the bulk of our work. These are typically 2,400-4,800 square foot custom or semi-custom homes with one or two furnaces in the attic, crawlspace, or garage. We use negative-pressure extraction - meaning the system is placed under vacuum while agitation tools dislodge debris from the duct walls, pulling it out through the vacuum rather than releasing it into your living space. A standard Danville residential clean covers every supply and return run, the main trunk line, and the plenum box where the furnace connects.

Commercial Duct Cleaning
Danville’s commercial spaces - dental offices near Sycamore Valley Road, restaurants along Hartz Avenue, small office suites around Blackhawk Plaza - need scheduled duct maintenance for indoor air quality and for keeping the HVAC units from working harder than necessary. We quote commercial jobs on a written, per-system basis after a walkthrough. No square-footage guesswork. No per-vent pricing games. One written price per system, before work begins.

Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace to every room. In Danville homes built in the 1980s and 1990s, these runs are often 6-inch round metal or flex duct, and the interior walls accumulate a coating of what we call “white lint” - a mix of drywall dust from original construction, laundry fibers, and dander that has been baked and re-circulated for decades. Supply cleaning focuses on full-length agitation of each run from the register end back toward the plenum.

Return Duct Cleaning
Return ducts are the problem child in Danville. They pull air back to the furnace, which means they pull everything that enters your home - dust from Diablo wind events, smoke particulate from fire season, pet hair, and, in Blackhawk homes especially, the fine silt that blows in through gaps around door seals. A return duct that hasn’t been cleaned in 10 years often shows a half-inch of impacted material against the duct wall. Our Danville return-duct cleans include aggressive agitation from both the return grille and the plenum access, plus a camera pass at the end so you can see the bare metal.

AfterTrusted Brands We Service in Danville
We work on systems from every major manufacturer, and our Danville trucks carry common replacement components from Rotobrush, Nikro, and Guardsman - the same professional-grade brands we use for source-removal cleaning, HEPA filtration, and duct sealing. If your system needs a new filter cabinet or a sealed access panel, we can typically pull the part from inventory and install it the same day rather than ordering and returning a week later. Honeywell thermostats and zone-control panels are common in Danville’s multi-zone homes, and our techs know how those systems respond to post-cleaning airflow changes.
Common Air Duct Cleaning Problems We See in Danville Homes

- Disconnected runs in 1980s Blackhawk attics. Original duct tape and cable ties degrade after 30 years. We regularly find branch runs that have separated from the main trunk, dumping conditioned air into an unconditioned attic. A camera inspection is the only way to catch this - a quick register-vacuum job will miss it entirely.
- Return-duct loading from Diablo wind events. Each fall, the dry offshore winds push fine dust and vegetation debris through exterior walls and into return ducts. Homes near open space along Diablo Road or the Las Trampas foothills get hit hardest. Without MERV-11 or better filtration at the return grille, that material ends up coating the blower motor and evaporator coil.
- Crushed flex runs in Sycamore Valley and Blackhawk. Flexible duct from the 1980s and 1990s has a lifespan measured in decades, not forever. When the outer vapor barrier fails, the inner coil loses structure and collapses. A crushed 12-inch return can cut airflow by 40% or more and pull unfiltered attic air into the home.
- Smoke particulate baked onto coils after wildfire season. Danville’s valley topography pools wildfire smoke from fires in the East Bay hills and beyond. When the AC runs during those events, fine particulate is drawn through the return and into the coil fins. Over one season, a coil can accumulate enough baked-on material to reduce airflow and recirculate the smoke smell for months.
Pricing for Air Duct Cleaning in Danville, CA
Here’s what you should expect to pay in Danville. A single-system home with basic duct layout runs $450-$650. A two-system home - common in Blackhawk and larger Sycamore Valley properties - runs $700-$1,100. Full-system jobs that include the furnace blower, evaporator coil, supply and return ducts, and video inspection fall between $900 and $1,400 depending on register count and access difficulty. If we find a crushed run or separated duct during the clean, that repair is quoted separately, in writing, before we touch it. You’ll never get a surprise line item at the end.

FAQs - Air Duct Cleaning in Danville

Yes. Danville sits in the inland San Ramon Valley where summer temperatures routinely exceed 95-100°F, running central AC for months at a time. That runtime alone accelerates dust and dander accumulation inside ductwork. Add the valley’s enclosed topography, which traps wildfire smoke during fire season, and you get contamination rates that coastal cities 20 miles west simply never experience. A Danville home may need full-system cleaning every 3-4 years, where a San Francisco or Berkeley condo could go 5-7 years between services. Call (806) 606-6902 and we’ll assess your system’s actual condition on camera. Estimates are free.
Blackhawk’s custom homes from the 1980s and 1990s were built before modern air-sealing standards, with multiple gaps around door frames, wall penetrations, and attic access points. During fall Diablo wind events, the dry, powerful offshore winds push fine dust and vegetation debris through those gaps into the home. The HVAC system’s return ducts pull that material directly into the duct network. The loading is heaviest in homes with basic fiberglass filters and no supplementary air sealing. We can show you the evidence on camera before any cleaning is quoted.
Video inspection shows you what’s actually inside your ducts before you spend a dollar on cleaning. In Danville’s older homes - particularly the 1980s Blackhawk and Sycamore Valley builds - a visual camera pass catches disconnected runs, crushed flex sections, and return-duct contamination that a surface-level register vacuum would never reveal. It also gives us a baseline image to compare against after the clean. Every CleanRun Danville job includes before-and-after photos of every duct run as a standard deliverable. You’re not paying extra for it. You’re paying for the cleaning, and the documentation comes with it.
Duct cleaning can remove most of the source material when the smoky smell is coming from particulate that settled inside the duct runs, on the blower motor, and on the evaporator coil. During valley fire events, smoke is drawn through the return ducts and deposits fine particles throughout the system. Source removal through negative-pressure extraction, combined with cleaning the blower and coil, addresses the material that re-releases odor when the system runs. What duct cleaning won’t do is remove odor from furniture, carpet, curtains, or wall surfaces. We’ll be straight about what the camera shows and what the limits are before any work is quoted.
In a 3,500-5,000 square foot Danville home with two systems and complex branching layouts - typical of Blackhawk and Sycamore Valley - a full-system duct cleaning takes 6 to 10 hours on site. That includes camera inspection of every run, negative-pressure extraction, supply and return cleaning, blower and coil cleaning, and the final photo documentation. Smaller single-system homes can be done in 4-5 hours. We quote the job in writing before work begins, so the time commitment is clear up front. Call (806) 606-6902 for a written estimate specific to your home.
