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 HVAC Cleaning Across Claremont
HVAC cleaning in Claremont usually means one of three things: an evaporator coil so loaded with reddish-tan grit that the system can’t pull heat out of the air, a blower wheel caked with dust that throws the motor out of balance, or duct runs shedding fiberglass into every register. We handle all three. Our crews work in Claremont every week, from the Craftsman bungalows near the Village to the 1950s ranch homes south of Foothill, and we arrive with a written price before any panel comes off. Call us at (806) 606-6902 and we’ll walk you through what we’d inspect, what it costs, and what the camera will show before and after.
Why CleanRun Air Duct Cleaning Is Claremont’s Preferred HVAC Cleaning Company
We’re independently owned and operated under the Haven Standard, and we’ve been doing this since 2013. That matters in Claremont because the housing stock here isn’t uniform. A 1920s faculty bungalow off College Avenue has a completely different duct system than a 1970s tract ranch near Claremont Boulevard, and both react differently to the dust that comes through the Cajon Pass. Our technicians know which registers to pull first in a north Claremont foothill home versus a flatland property south of Foothill, because we’ve cleaned both hundreds of times.
Every job ends with a Documented Photo Record. You see the inside of every duct run, before and after, on camera. Not a summary paragraph. Not a vague assurance. Photographs. That record exists because our founder, Tomas Reyes, built the company on a simple rule: show the customer what was actually found, not what we claim was found. When we open a supply plenum in Claremont and find a half-inch of caked Mojave silt on the evaporator coil, you’ll see the photo before we quote the work.
We also run background-checked, uniformed technicians under Haven Standard Clause 3, and we answer the phone with a live person. No routing trees, no call-back queue. When you call from Claremont, you reach someone who can schedule the visit and tell you what to expect.
Our HVAC Cleaning Services in Claremont
Evaporator Coil Cleaning
The evaporator coil is where your system actually removes heat and humidity from indoor air. In Claremont, especially north of Baseline Road, that coil becomes a collection point for wind-driven Mojave silicate dust after every Santa Ana event. A fouled coil raises head pressure, drops efficiency, and eventually freezes over. We pull the access panel, photograph the coil, clean it with professional-grade equipment from trade brands like Rotobrush and Nikro, and show you the before and after. A typical evaporator coil cleaning in Claremont runs $180-$340 depending on access and buildup.
Blower Cleaning
The blower wheel moves every cubic foot of conditioned air through your duct runs. When it’s loaded with dust from the Cajon Pass wind corridor, it has to spin harder to move the same volume. That means higher amp draw, more motor heat, and faster bearing wear. We remove the blower assembly, clean each individual fin, and reinstall it balanced. In Claremont homes with original 1960s-era blower motors, we often see a measurable drop in motor temperature within 24 hours of cleaning. Blower cleaning typically runs $160-$280 in Claremont.
Condenser Cleaning
The outdoor condenser coil sits in Claremont’s dry, dusty air every day. It pulls in whatever the wind carries: leaf litter from the Village’s mature oaks, fine dust off the alluvial fan, pollen from spring bloom cycles. A dirty condenser coil reduces system capacity and shortens compressor life. We clean it with coil-specific cleaners and straighten bent fins where needed. Expect to pay $150-$260 for a Claremont condenser cleaning, more if the unit sits in heavy landscaping that requires disassembly.
Air Handler Cleaning
The air handler cabinet is the intersection point: return air comes in, supply air goes out, and every contaminant in between collects here. On Claremont ranch homes built south of Foothill, we usually find insulation fibers, pet dander, and fine desert grit accumulated on the blower housing and motor. We clean the interior of the cabinet, the blower assembly, and the coil surfaces, then photograph the result. Air handler cleaning in Claremont typically falls between $220-$400 depending on the unit’s size and age.

BeforeAfterTrusted Brands We Service in Claremont
We clean systems built around equipment from every major manufacturer, and we keep replacement filters, belts, and access hardware stocked for Claremont homes specifically. That means when we open a Honeywell air cleaner cabinet or an Aprilaire media filter housing, we’re not waiting on parts. Many Claremont homes run their HVAC systems ten months a year, which means the Aprilaire media filter we inspect during a routine HVAC cleaning often looks far worse than the one-year change interval suggests. We’ll note that in the photo record and give you a written recommendation, not a vague warning. Our standard scope covers the full air handler, coil, blower, and duct runs - never just a register and a shop-vac pass. We put the documented evidence in your hands, every time.
Common HVAC Cleaning Problems We See in Claremont Homes
- Santa Ana-driven Mojave grit loading. After each Santa Ana wind event, homes north of Baseline Road show a distinctive reddish-tan dust on registers and inside the air handler. It’s fine silicate from the Mojave, forced through the Cajon Pass and into Claremont’s foothill neighborhoods. Standard 1-inch furnace filters simply can’t catch it. Source removal before each heating season is the only reliable fix.
- Fiberglass shedding from 1950s-1970s ductwork. Claremont’s tract ranch homes south of Foothill Boulevard were built with insulated ductwork that’s now 50-70 years old. The insulation breaks down in Claremont’s extremely low humidity, releasing fiberglass particles into the airstream. You’ll see it as a fine white dust on register grilles. Those ducts need sealing or replacement, not just cleaning.
- Desiccated duct seals pulling in attic dust. Claremont’s inland air sits at extremely low humidity for most of the year. Duct mastic and flex duct linings dry out and crack here faster than in coastal cities. When seals fail, the supply side pulls air from the attic, not the return grille. That means dust, allergens, and whatever else lives in the attic ends up coming through your supply registers.
- Clogged evaporator coils in college-adjacent rentals. The older faculty housing and rental properties around the Claremont Colleges often have patchwork duct systems and deferred maintenance. We regularly find evaporator coils that haven’t been cleaned in years, coated in a paste of dust and cooking residue. The tenants never complain and the owner never sees it. A camera inspection changes that.

FAQs - HVAC Cleaning in Claremont
North Claremont homes above Baseline Road should have a full HVAC inspection and coil cleaning every 18-24 months, and duct cleaning every 3-4 years. That’s shorter than what we recommend for Pomona or Upland because the Cajon Pass funnels a direct stream of Mojave fine particulate into those foothill neighborhoods after each Santa Ana wind event. Homes a few miles south, below Foothill, can often go 4-5 years without full duct cleaning. If you notice a reddish-tan film on your registers within a month of cleaning them, you’re in the high-loading zone. Call (806) 606-6902 and we can tell you what we’re seeing in your specific neighborhood.
Yes. That dust is fine Mojave silicate, and if it’s visible on your registers, it’s almost certainly inside the air handler, on the evaporator coil, and coating the blower wheel. Visible register dust is the trailing edge of a much larger buildup. In Claremont homes north of Baseline, we routinely find a quarter-inch or more of that same grit on the coil surface after a single Santa Ana season. The fix is source removal: negative-pressure extraction with HEPA filtration, not just wiping the register grilles. Call us at (806) 606-6902 for a written scope.
Because the fiberglass isn’t coming through the filter. It’s coming from inside the duct runs. Claremont’s 1920s-1940s Craftsman bungalows near the Village and the Colleges often still have original insulated ductwork, and that insulation is breaking down. In Claremont’s dry air, the material desiccates and sheds into the airstream on the supply side, meaning it bypasses the filter entirely. The permanent fix is duct repair or replacement, not more cleaning. We document the shedding with camera inspection before recommending anything.
Those homes, largely built in the 1950s through 1970s, share two characteristics: undersized return ducts and aging insulated flex runs. The undersized returns make the system work harder and pull harder on every seam and joint, which accelerates particle intrusion. The aging flex linings break down in the low humidity and release particulate into the air handler. So when we clean a south-of-Foothill tract home, we’re not just removing accumulated dust. We’re checking the ductwork for the kind of deterioration that cleaning alone won’t fix. We’ll show you the photos.
Yes. Homes with wood-burning stoves or fireplaces in Claremont’s foothill areas put significantly more particulate into the indoor air, and that particulate eventually ends up in the duct system. The fine ash and creosote-laced dust clings to coil surfaces, blower fins, and duct walls, accelerating buildup. We recommend those homeowners inspect the air handler and blower every year, and clean the full system every 2-3 years. The camera record tells you what’s actually needed.
If your HVAC system in Claremont is using more energy, struggling to hold temperature, or pushing visible dust through the registers, call us at (806) 606-6902. We’ll give you a written price before any work begins, document everything with photos before and after, and back the job with our 365-Day Done Right Promise. That’s how it should work.
