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.

AfterFast, Reliable Air Duct Cleaning Across Claremont
Air duct cleaning in Claremont typically runs $450-$950 for a full system on a standard single-family home, and most jobs are completed in a single visit. The bigger cost driver here isn’t square footage; it’s what the San Gabriels and the Cajon Pass push into your ductwork. We’ve been cleaning ducts in Claremont since 2013, and the loading pattern we see in this city is different from anywhere else in the Inland Empire corridor. If your registers show a reddish-tan grit after a Santa Ana, call (806) 606-6902 for a written price before any work begins.
Why CleanRun Air Duct Cleaning Is Claremont’s Preferred Air Duct Cleaning Company
Claremont homeowners tend to research before they call. They want to see a written price, they want documentation of what was actually done, and they don’t want a technician who treats duct cleaning like a shop-vac side job. That’s the customer we built CleanRun around, starting with our first job in 2013. Tomas Reyes, our owner, set the standard early: photograph every duct run before and after, put every quote in writing before a single panel comes off, and back the work for 365 days. That’s the Haven Standard, and it applies to every Claremont job.
Our crews know Claremont’s housing stock, which matters more here than in most cities. A 1920s Craftsman bungalow near the Village has a completely different duct configuration than a 1960s tract ranch south of Foothill Boulevard. We don’t send a one-size-fits-all technician. We send someone who knows what they’re going to find before they open the first register, because they’ve opened hundreds of them in this city.
Our Air Duct Cleaning Services in Claremont
Residential Duct Cleaning
Most Claremont homes we service fall into two categories: pre-war Craftsman and college-adjacent housing near the Claremont Colleges, and the 1950s-1970s ranch belt south of Foothill Boulevard. The older homes often have undersized return ducts and patchwork repairs from decades of remodels. The mid-century homes have original galvanized ductwork with failed seals. Both pull more particulate into the airstream than the filter can catch. Our residential cleaning covers supply runs, return runs, the plenum, and the air handler cabinet, with a camera record of every run before and after.
Commercial Duct Cleaning
Claremont’s commercial spaces, from the Village storefronts to office suites near the Colleges, carry higher occupant density than residential systems, which means a faster accumulation cycle. We clean commercial duct systems in the same documented way we clean homes: written scope, written price, photo record. For retail and office spaces, we schedule around operating hours so you don’t lose a business day.
Supply Duct Cleaning
Supply ducts are the runs that deliver conditioned air to each room. In Claremont, especially north of Baseline Road, these are the ducts most affected by the reddish-tan Mojave grit that rides Santa Ana winds through the Cajon Pass. We source-remove this dust using negative-pressure extraction and rotary agitation tools, including Rotobrush and Nikro equipment. The goal is to remove the particulate from the duct wall, not just loosen it.
Return Duct Cleaning
Return ducts pull air back to the system, and in Claremont homes with leaky returns, they’re also pulling air from crawlspaces and attics. That means whatever is in those spaces, fiberglass shed from deteriorated insulation, rodent debris, decades of dust, ends up in your return air. We clean returns as a separate scope item, not an afterthought, because in this city the return side is frequently the dirtier side.

BeforeAfterHow Claremont’s Dust Problem Changes the Cleaning Calculus
Claremont sits at the eastern edge of the Los Angeles Basin, right where the San Gabriel Mountains form a wall that traps basin smog. The South Coast Air Quality Management District’s own monitoring consistently ranks this corridor among the worst in the nation for PM2.5, the fine particulate that standard filters let through. But that’s only half the story. When Santa Ana winds blow through the Cajon Pass, they carry fine Mojave Desert dust directly into foothill neighborhoods, and north Claremont homes above Baseline Road get the worst of it. That’s a two-source loading pattern: trapped basin smog from the west, wind-driven desert dust from the northeast. Coastal cities don’t get the second source. Even Pomona and Upland, just a few miles away, see measurably less of the reddish-tan grit because they sit at lower elevation with less direct exposure to the wind corridor.
What this means practically: Claremont ducts load faster than the five-year interval that gets quoted in generic online guides. If you live north of Baseline Road, we typically see meaningful buildup within two to three years, especially after a heavy Santa Ana season. South of Foothill, the loading is slower but the older ductwork introduces different problems, rusted seams, deteriorated seals, fiberglass shedding from desiccated insulation. The fix isn’t always a simple cleaning. Sometimes it’s cleaning plus targeted sealing or insulation remediation, and we’ll show you the camera evidence before recommending anything.
Trusted Equipment and Brands We Use in Claremont
We run professional-grade equipment from Rotobrush and Nikro, and we use Guardsman and Honeywell products for sanitizing and filtration work where it’s warranted. These aren’t decorative brand names we list for credibility; they’re the tools our crews actually operate on Claremont jobs. If you’re comparing quotes, you can look up any of these brands independently and verify what we’re using. The equipment matters because fine PM2.5 and silica dust require negative-pressure extraction and rotary agitation, not a shop vac and a prayer.
What We Actually See When We Open Claremont Ductwork
- Reddish-tan silicate grit in north Claremont foothill homes: After Santa Ana events, registers north of Baseline Road are frequently caked with fine desert dust that has blown through the Cajon Pass. This is the single most common finding in north Claremont, and it’s noticeably heavier than what we find in Pomona or Upland.
- Fiberglass shedding from desiccated duct insulation: Claremont’s ultra-low humidity dries out the insulation lining on older ductwork, especially in 1950s-1970s ranch homes south of Foothill Boulevard. The insulation becomes brittle, breaks down, and sheds fibers into the airstream that a MERV 8 filter cannot capture.
- Failed seals and rusted seams pulling crawlspace air into the return: Original galvanized ductwork in mid-century Claremont homes frequently has deteriorated seals at the joints. The return side draws air from the crawlspace through those gaps, which is why the return ducts are often dirtier than the supply ducts.
- Patchwork repairs in pre-war homes near the Colleges: Craftsman bungalows and faculty housing near the Claremont Colleges have had decades of ad-hoc repairs and remodels. Duct sizes don’t match, connections are improvised, and airflow suffers. These systems need a careful inspection before any cleaning so we don’t damage fragile, aging components.
Pricing for Air Duct Cleaning in Claremont, CA
A full system cleaning in Claremont, including supply runs, return runs, plenum, and air handler cabinet, typically runs $450-$950 for a single-family home under 3,000 square feet. Smaller homes and single-story ranches usually fall on the lower end. Larger homes, especially two-story builds with long duct runs, land higher. Commercial systems in Claremont range $750-$1,800 depending on the number of units and accessible ductwork.
What affects your price more than anything: the age and condition of your ductwork, the number of runs, and whether you need sealing or insulation work beyond the cleaning itself. We give you a written price before any work starts, under Haven Standard Clause 1. That price is a flat price per system, not a per-vent figure that grows once we’re on site. We also offer a free second opinion on any written estimate you’ve received from another company. Call (806) 606-6902 and we’ll put our number next to theirs in writing.

FAQs - Air Duct Cleaning in Claremont
Homes north of Baseline Road typically need cleaning every two to three years because Santa Ana winds through the Cajon Pass deliver fine Mojave Desert dust directly into foothill ductwork. Homes south of Foothill Boulevard can usually go three to five years, though older ranch homes with compromised seals or desiccated insulation may need cleaning sooner. Call (806) 606-6902 and we’ll give you an honest interval based on your home’s location and duct condition.
Claremont sits directly downwind of the Cajon Pass, so when Santa Ana winds blow, they funnel fine silicate dust from the Mojave Desert straight into foothill neighborhoods north of Baseline Road. Pomona sits lower and further from the wind corridor, so it receives measurably less of that reddish-tan desert grit. The difference is geographic, not a problem with your HVAC system.
Yes. Negative-pressure extraction, where the system is placed under vacuum while rotary agitation tools dislodge particulate from the duct walls, is the standard method for source-removing fine dust including PM2.5. This is the approach we use on every Claremont job, following NADCA standards, with Rotobrush and Nikro equipment. The before-and-after camera record shows what was removed.
Yes. Pre-war homes near the Village and the Colleges often have undersized returns, patchwork duct modifications from decades of remodels, and fragile materials that can be damaged by aggressive cleaning. Our crews run a camera inspection first and adjust the agitation level and tooling to match the ductwork’s age and condition. We don’t use the same technique on a 1920s Craftsman that we use on a 1970s ranch.
Late fall, after the Santa Ana season winds down, is the most effective time to clean Claremont ducts. Most of the October-December wind events have already deposited their dust, and cleaning then gives you the longest clean period before the next loading cycle. If you clean in late summer, the first Santa Ana of the season simply reloads your ductwork. We’ll schedule accordingly if you call (806) 606-6902.
