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 in San Dimas, CA: What Homeowners at the Foothills Actually Face
Air duct cleaning in San Dimas typically costs between $425 and $780 for a full single-family system, and the condition of your ductwork depends heavily on where your home sits relative to San Dimas Canyon. Homes in this part of the eastern San Gabriel Valley collect dust, ash, and fine particulate far faster than properties just a few miles west. You’ll see it in the register dust that returns within days of wiping every surface. Call (806) 606-6902 to get a written price before anyone opens a panel at your San Dimas home.
Why CleanRun Air Duct Cleaning Is the San Dimas Choice
We’ve worked in enough San Dimas attics to know what 150°F does to duct tape and fiberglass liner. Homes in Via Verde, the older ranch tracts off Arrow Highway, and the neighborhoods below San Dimas Canyon all share a common thread: original 1960s and 1970s ductwork that was not built for decades of Santa Ana winds and wildfire smoke. Our techs photograph the inside of every duct run before any tool touches the metal. You get those images as part of the job record, not as an upsell. That documentation is the reason homeowners keep our number. Tomas Reyes, who runs CleanRun, built this company in 2013 on a simple rule that has not changed since: a written price before work starts, every time, no exceptions.
We coordinate scheduling for San Dimas from our Los Angeles office, and our crews know this city’s streets. When you describe a 1978 ranch near Lone Hill Avenue with a return that never seemed to pull air right, we know what we’re likely to find before we even climb the ladder. The 365-Day Done Right Promise is in writing on every job. If the work is not right, we make it right. That is not a marketing line; it is a clause in the document you receive before we clean a single register.
Our Air Duct Cleaning Services in San Dimas
Residential Duct Cleaning
Most San Dimas homes we service are single-story ranch or two-story tract builds from the 1960s through the 1980s. Residential cleaning here requires more than a vacuum attachment. We use negative-pressure extraction with agitation tools, because the fine material packed into these ducts does not lift on its own. A standard cleaning for a 1,800 to 2,600 square foot San Dimas home runs $425 to $780 depending on the number of duct runs. We photograph every supply and return run before and after, and you receive those images with your job record.
Commercial Duct Cleaning
Commercial spaces in San Dimas, from the retail plazas off Bonita Avenue to the medical offices near the 57, deal with the same foothill particulate load as residential properties. Our commercial cleaning uses the same documented-before-and-after standard we apply to homes: no exceptions. Written pricing, scheduled around your operating hours, and a full photo record of the ductwork inside every plenum and trunk line. Expect commercial quotes to reflect square footage and the complexity of the duct runs.
Supply Duct Cleaning
Supply ducts in San Dimas carry the air you breathe back into the rooms. In older systems, these runs are frequently lined with a fiberglass material that has been degrading in attic heat for 40 to 50 years. The liner sheds into the air stream even when your filter looks clean from the front. We clean supply runs with source-removal agitation, then inspect every joint with a camera to identify where air is leaking into the attic instead of reaching the register. San Dimas supply duct cleaning is usually included in a full system clean.
Return Duct Cleaning
Return ducts are the most commonly compromised runs in San Dimas. Original galvanized returns from the 1960s and 1970s were sealed with tape and staples at the joints. In an attic that hits 150°F day after summer day, that tape dries, releases, and opens gaps. The air handler then pulls attic dust, loose insulation fibers, and whatever the Santa Anas blew through your vents directly into the system. Our techs routinely find crushed flex runs and separated metal joints on San Dimas returns. We clean the run, seal the joint with mastic, and replace collapsed sections where needed.

BeforeAfterTrusted Brands We Service in San Dimas
We work on systems built around Honeywell thermostats and filtration, Aprilaire media cabinets, and Abatement Technologies filtration equipment. Homes in San Dimas that run Aprilaire or Honeywell media cabinets still get particulate past the filter housing when duct liner is breaking down or return joints are open. Our technicians stock common replacement filters and components for these brands, and we can install Guardsman access panels to make future cleaning and inspection easier. Naming the equipment matters: you should be able to look up what we put into your home before you agree to the price.
Common Air Duct Cleaning Problems We See in San Dimas Homes
- Separated return duct joints in hot attics. Original tape from the 1960s and 1970s dries out and releases after decades of San Dimas summer heat, opening gaps that pull attic insulation into the air handler.
- Fiberglass liner deterioration. Older duct runs lined with fiberglass shed particles into supplies even when the return filter looks clean, a problem that accelerates when attic temps sit above 150°F for weeks.
- Post-wildfire ash accumulation. After events like the 2014 Colby Fire in the ridgelines above Glendora and San Dimas, fine gray ash bypasses standard 1-inch filters and settles in ducts as collection chambers that release contaminants for months.
- Crushed flex runs from original construction. Flex duct installed during the original tract build decades ago is often collapsed or kinked in hard-to-reach attic corners, restricting airflow until a video inspection shows the actual failure.
Pricing for Air Duct Cleaning in San Dimas, CA
Typical whole-home air duct cleaning in San Dimas runs between $425 and $780. Smaller condos or homes with a single air handler and under 10 duct runs are at the lower end. Larger homes in the newer developments around San Dimas Canyon with multiple returns or zoning systems run toward the upper end. If we find separated joints or crushed flex during the cleaning, sealing and repair are quoted separately, in writing, before we touch anything. You know the full price before work starts. That is Haven Standard Clause 1, and it is not negotiable. If you received another company’s written estimate, bring it: we provide a Free Second Opinion on any written quote.
Every job includes the Documented Photo Record of the inside of every duct run, before and after. That record is yours whether we find a relatively clean system or one loaded with three inches of debris at the first elbow.

FAQs - Air Duct Cleaning in San Dimas
Whole-home air duct cleaning in San Dimas costs between $425 and $780 for a standard single-family system. The price depends on the number of duct runs, whether you have multiple air handlers, and the condition of the existing runs. CleanRun provides a written price before any work starts, and that price covers the full cleaning plus a Documented Photo Record of every run before and after. Call (806) 606-6902 for an exact quote, and the estimate is free.
Yes. Every San Dimas cleaning uses negative-pressure extraction with an agitation tool - typically Rotobrush or Nikro equipment - and HEPA-filtered collection at the point of airflow. The agitation step is not optional here, because the fine ash and chaparral dust that accumulates in foothill ducts will not release with vacuum alone. We also camera-inspect each run after cleaning to confirm what was removed and what might need sealing.
San Dimas sits at the mouth of San Dimas Canyon against the San Gabriel Mountains. Santa Ana wind events push chaparral dust, pollen, and wildfire ash from the Angeles National Forest directly into foothill homes, while the city’s position in the eastern San Gabriel Valley’s terminal airshed means particulate pollution collects here rather than dispersing. That combination fills ductwork faster than it does in flatland communities a few miles west. Regular filter changes help, but they do not stop the accumulation inside ducts.
For most San Dimas homes, a full cleaning every 3 to 5 years is reasonable, but homes below the canyon or downwind of recent burn scars may need attention more often. If you wiped a register clean and dust returned within a week, that is a sign the ducts are re-releasing what is already in them. If smoke from a wildfire moved through the area, an inspection sooner than later is worth doing. Call (806) 606-6902 and we’ll schedule a video inspection first.
Bring it. CleanRun offers a Free Second Opinion on any written estimate. We put our own number next to it, in writing, and explain the difference if there is one. No pressure, no obligation. The reason we can do this is simple: our quote includes a documented before-and-after photo record, and a written guarantee under the 365-Day Done Right Promise. Most quotes that look cheaper don’t. Call (806) 606-6902 and we’ll review what you have.
The Foothill Factor: What San Dimas Ducts Actually Contain
Here is what we find in San Dimas that we rarely see in flatland cities. On a Via Verde ranch built in 1974, our tech found the original galvanized return duct had separated at a joint in the attic. Daytime attic temperatures here push past 150°F, so the old tape had dried and released, pulling loose insulation fibers straight into the air handler. After a camera inspection confirmed the crushed flex run and a 3-inch separation, we used negative pressure with a Rotobrush agitation tool for source removal, then sealed the joint with mastic and replaced the crushed section. Post-job static pressure dropped 22%, and the homeowner reported the dust on her registers stopped within a week.
The geographic reality of San Dimas means your ductwork is a collection point for what the Santa Anas carry down San Dimas Canyon. Chaparral dust, pollen, and after a fire season, fine gray ash from the ridgelines above the city. The 2014 Colby Fire on the slopes above Glendora and San Dimas left entire systems loaded with ash that bypassed residential filters. Standard 1-inch filters cannot capture that material. It settles in the duct runs and re-enters your air every time the blower kicks on. A post-fire service surge is a real thing in this city, because the problem does not show up at the register until weeks after the smoke clears.
The old housing stock makes this worse. Original flex and galvanized sheet-metal ductwork from the 1960s through the 1980s is now 40 to 50 years old. The liner inside those runs deteriorates in attic heat, and joints separate over time. The result is not just dirty ducts: it is ductwork actively pulling attic air, insulation fibers, and whatever the wind brought through the vents, directly into the air handler loop. Our San Dimas customers often call us for a cleaning and discover the actual fix is sealing the joints and replacing collapsed runs. That is why we document everything with video inspection before and after: you need to see the failure to know a cleaning alone won’t solve it.
When you call CleanRun for air duct cleaning in San Dimas, you get a written price before work begins, a camera inspection of every run, cleaning with professional-grade equipment from Rotobrush, Nikro, or Abatement Technologies, and a photo record of the inside of your ducts when we finish. Tomas Reyes has run the company that way since 2013, and the 365-Day Done Right Promise is in writing on every job. To see what is actually inside your ducts, call (806) 606-6902 and schedule a video inspection. No pressure, no bait pricing. Just a documented answer to a question you have probably been guessing at for years.
