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 San Dimas
HVAC cleaning in San Dimas typically runs $425-$780 for a full system clean on a 1,500-2,200 sq ft home, and the work usually takes 3-5 hours. That price covers the evaporator coil, blower assembly, air handler, and the full duct run, with a documented photo record of every section before and after. We’re CleanRun Air Duct Cleaning, and we’ve been doing this work long enough to know that San Dimas homes need a different approach than houses ten miles west. The mountains behind you change everything about how fast your ducts load up and what actually needs fixing once we get inside. Call (806) 606-6902 and we’ll give you a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is San Dimas’s Preferred HVAC Cleaning Company
We’re HVAC Cleaning specialists who show up with a camera, a written scope, and the equipment to do the job properly - Rotobrush agitation tools, Nikro HEPA filtration, and Guardsman coil treatment products. Every visit to San Dimas ends with a documented photo record of the inside of every duct run, not a vague “looks better now.” Tomas Reyes, who runs the company, set the standard in 2013: written price before work starts, every time, no exceptions. That’s Haven Standard Clause 1, and it applies to every home on every street from Via Verde to the 210 corridor.
Our crews know the San Dimas housing stock because we’ve spent years opening up the same 1970s ranch-style builds and 1980s Via Verde tracts that dominate the city. We know what original galvanized trunk lines look like after 45 years, where the flex duct runs fail first in a 150°F attic, and what Santa Ana ash does to a coil that has never been cleaned. That local knowledge means we don’t waste your time diagnosing what we already know from the last ten homes on the same block. The 365-Day Done Right Promise backs all of it, in writing, on every job.
Key Takeaways
- San Dimas pricing: full HVAC clean runs $425-$780 on typical homes; coil-only cleaning starts around $225.
- Written price before work starts: no call-for-quote games, no per-vent pricing, no surprise invoice.
- Documented photo record of every duct run before and after, delivered with the job record.
- San Dimas-specific: foothill dust, wildfire ash, and 50-year-old flex duct mean cleaning often uncovers sealing work that matters more than the clean itself.
Our HVAC Cleaning Services in San Dimas
Evaporator Coil Cleaning
An evaporator coil in a San Dimas home rarely fails from age alone. It fails because fine gray ash from the San Gabriel ridgelines settles on the coil face, mixes with condensation, and bakes into a paste that chokes airflow. We clean the coil in place with professional-grade coil cleaner, flush the condensate line, and treat the surface with Guardsman coil treatment to slow re-accumulation. A coil cleaning on a typical San Dimas system runs $225-$385.
Blower Cleaning
The blower wheel is what pulls air through your filter and pushes it past the coil, and in foothill homes it accumulates a layer of fine particulate that reduces airflow before you ever notice it at the register. We remove the blower assembly, clean each blade, and reinstall with the motor checked for bearing wear and proper amp draw. On older San Dimas units, this is also when we spot failing capacitors and belts before they strand you in August. Blower cleaning usually adds $120-$200 to the full-system price.
Condenser Cleaning
Your outdoor condenser sits through Santa Ana wind events, collects chaparral dust and cottonwood debris, and quietly loses efficiency. In San Dimas, where 1960s-1980s homes often run older 10-12 SEER units, a dirty condenser coil is the difference between a system that cools and a system that runs constantly and still can’t hold 75°F. We clean the condenser coil with low-pressure water and coil cleaner, straighten bent fins, and clear the pad of debris. Condenser cleaning runs $150-$275 on a standard residential unit.
Air Handler Cleaning
The air handler cabinet is the transition point where attic air, return duct debris, and coil condensation all meet, and in Via Verde homes it’s often the dirtiest component on the entire system. We vacuum and wipe the cabinet interior, inspect the drain pan, and verify the blower housing is sealed. If we find standing water, rust, or a cracked pan, you’ll see it in the photo record and we’ll quote the repair as a separate written line item. Air handler cleaning is included in the full-system price.

Common HVAC Cleaning Problems We See in San Dimas Homes
- Ash-laden ducts after Santa Ana events: every strong wind event off the Angeles National Forest pushes ultrafine ash and chaparral dust through the canyon mouth and into supply and return ducts. Standard 1-inch filters can’t catch particles this fine; the coil gets coated and airflow drops within one season.
- Collapsed flex duct in Via Verde attics: original 1970s and 1980s flex runs separate at joints when attic temperatures push past 150°F, and the liner sags and crushes. Loose fiberglass insulation gets pulled directly into the living-space air stream, and rooms stop hitting their set temperature.
- Post-wildfire gray ash layers: after fire events like the 2014 Colby Fire on the ridges directly above San Dimas and Glendora, ducts carry a fine gray ash layer that residential filters never touch. A vacuum-only clean without HEPA filtration and mechanical agitation just resurfaces that ash into the home.
- Coated evaporator coils from continuous run cycles: during heat waves, homes seal up and systems run nonstop, and the coil becomes a collection point for whatever the return duct delivers. Once coated, the system loses cooling capacity and runs longer, which pulls more attic air through any existing duct gaps.

FAQs - HVAC Cleaning in San Dimas
San Dimas sits at the mouth of San Dimas Canyon, directly in the path of Santa Ana winds that push chaparral dust, pollen, and wildfire ash from the Angeles National Forest into foothill homes, while the eastern San Gabriel Valley’s terminal airshed traps PM2.5 against the mountains. Ductwork here accumulates contaminants far faster than in flatland cities a few miles west. If you’re seeing dust on registers within weeks of wiping them down, the ducts are likely the source. Call (806) 606-6902 and we’ll show you with a camera what’s actually inside.
Wildfire smoke carries ultrafine ash particles that pass straight through a 1-inch residential filter, coat the evaporator coil, and settle as a fine gray layer inside duct runs. After the 2014 Colby Fire burned the slopes directly above San Dimas and Glendora, our crews consistently found systems loaded with ash that a standard filter never caught. The fix is HEPA-filtered negative-air extraction with mechanical agitation to physically remove the ash, not just vacuum out loose debris. We’ll show you the before-and-after photos of your own system.
Yes, in San Dimas a strong Santa Ana event can load ducts with chaparral dust, pollen, and fine particulate even without a wildfire, and letting that sit through a heat wave bakes it onto the coil. The question is whether your ducts are already at the point where airflow is dropping. A camera inspection answers that in about 20 minutes, and the inspection is included when you schedule a cleaning. Call (806) 606-6902 and we’ll get you on the schedule.
The most common problem in Via Verde homes is crushed or separated 6-inch flex duct in the attic, where summer heat above 150°F softens the liner and causes it to separate at a joint. On a 1970s ranch-style home in that tract, we pulled a crushed run where the liner had failed completely and loose fiberglass insulation was being drawn directly into the supply side. Cleaning alone won’t fix that - the failed run has to be removed and the remaining trunk sealed. We’ll show you the camera footage before we recommend anything.
Cleaning alone rarely fixes airflow problems in 1960s-1980s San Dimas homes, because the root cause is usually separated flex duct joints and gaps in the galvanized trunk that pull hot attic air into the system. We find this in most older Via Verde builds we open up. The honest answer is that cleaning removes the contamination, but sealing is what restores airflow and room-to-room temperature balance. We’ll quote both as separate written line items so you can see exactly what each costs and decide from evidence, not persuasion.
