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 Concord
HVAC cleaning in Concord means dealing with what the Diablo Valley throws at your system: wildfire smoke particulate, Central Valley dust, and attic heat that bakes 50-year-old ductwork for months at a stretch. A basic cleaning that only brushes the supply ducts won’t fix what’s actually wrong in most Concord homes. You need a documented inspection first, then a cleaning plan built around what the camera found. That’s how we work, and it’s why homeowners from Clayton Road to Willow Pass Road call us at (806) 606-6902 when their systems need real work, not a vacuum demo.
Why CleanRun Air Duct Cleaning Is Concord’s Preferred HVAC Cleaning Company
Founded in 2013, CleanRun has built its reputation on one practice: we show you what’s inside your ducts before we touch them. Every HVAC Cleaning job in Concord starts with a written price, and ends with a documented photo record of every duct run we worked on. No exceptions. That’s Haven Standard Clause 1 in writing, and it’s the reason Concord homeowners who research before they hire keep our number.
Concord’s housing stock is specific. The ranch tract homes built along Clayton Road and the surrounding corridors between 1955 and 1975 often have original sheet-metal supply trunks and early fiberglass duct board that’s now past its service life. We know what that looks like from the inside, because we’ve inspected and cleaned thousands of these systems across Contra Costa County. Tomas Reyes, who leads our crews, has spent more than a decade documenting exactly what failure looks like in these attics, and he trains every technician to inspect before they clean.
We schedule Concord work with realistic job times. An older ranch with attic-routed duct runs takes longer than a newer two-story in Walnut Creek, and we build that into the written quote you get before we arrive. No price changes after the van pulls up.
Our HVAC Cleaning Services in Concord
Evaporator Coil Cleaning
The evaporator coil is the part of your AC that actually gets cold. It sits in the air handler and pulls moisture out of the air as it cools, which means it collects everything that passes through: wildfire smoke residue, dust from unpaved roads, pet dander. In Concord, where summer heat keeps systems running for months, a coated coil costs you real money in efficiency loss. Most evaporator coil cleaning jobs in Concord run $180-$340 depending on access and how badly the coil is fouled. If the coil is buried in a 1970s air handler in a tight attic closet, expect the higher end.
Air Handler Cleaning
Your air handler is the box that holds the blower, the coil, and often the filter. In Concord’s older tractor homes, the air handler is frequently in the attic, where it’s been sitting in 140°F heat for decades. Cleaning the air handler means removing the blower assembly, cleaning the housing, and inspecting the cabinet for gaps where attic air gets pulled into the supply side. We see this constantly in Concord: air handlers pulling unfiltered attic air through cracked cabinets. Air handler cleaning typically runs $220-$400 in Concord, with access difficulty being the biggest variable. If your air handler is in a garage or closet, the range shifts lower.
Condenser Cleaning
The condenser is the unit outside. In Concord, it’s not just heat that works against it. It’s the dust from unpaved driveways, the cottonwood from creek corridors, and the fine particulate that settles out of trapped valley air. A clogged condenser coil forces the compressor to run hotter, and in a city that hits 95-105°F regularly, that shortens equipment life. Condenser cleaning in Concord runs $120-$220 for most single-family homes. We clean the coil fins, clear debris from inside the unit, and check the refrigerant line condition as part of the job.
Coil Treatment
After cleaning, we apply a coil treatment that slows the re-accumulation of grime. In Concord’s summer, where systems run continuously, a treated coil stays cleaner longer than an untreated one. This is a standard part of our evaporator and condenser cleaning jobs, not an add-on line item. The treatment is included in the ranges above.

BeforeAfterTrusted Brands We Service in Concord
Most Concord homes we work on have systems from the usual manufacturers: Carrier, Trane, Lennox, Rheem, Goodman, and York. We service them all, and we stock common replacement parts locally so a collapsed duct section or a worn blower wheel doesn’t leave you waiting on a parts shipment. For duct rehabilitation work, we use Guardsman and Rotobrush equipment, and for air quality verification we use Honeywell monitors. If you want to research the tools before you agree to a price, you can look those brands up independently. We name them on the page because our crews actually use them.
Common HVAC Cleaning Problems We See in Concord Homes
Here’s what we actually document in Concord attics and garages, week after week:
- Collapsed or detached duct sections in attic runs. The combination of extreme attic heat, 50-year-old flex duct liners, and deferred maintenance means the duct system itself is often the contamination source, not surface dust. A cleaning that doesn’t find this just redistributes fiberglass and debris back into the house.
- Fiberglass duct board degradation. Original duct board from the 1960s and 70s sheds fibers as the binding resins break down. We see this in supply trunks along Clayton Road and Willow Pass Road corridors. The camera shows it, and it’s visible in the photo record we give you.
- Post-wildfire smoke residue on blower motors and coils. During the 2018 Camp Fire, Concord’s AQI spiked above coastal cities and stayed elevated for days. Homeowners who ran their AC to escape the heat pulled PM2.5 into the entire system. That residue stays on the blower wheel and coil until someone physically removes it. Skipping coil cleaning after a smoke event leaves a smoky odor and reduced cooling even after the ducts are done.
- Heavy particulate loading from unpaved roads and open land. Concord’s rural fringe, especially east toward Clayton and northeast near the Port Chicago corridor, has properties on unpaved lanes. That dust loads air handlers faster than in dense suburban tracts. If you live on an unpaved road, a one-time cleaning won’t hold. You need a realistic interval.

The biggest cost variable in Concord is access. An attic air handler in a 1968 ranch off Clayton Road with 120°F attic temps in July takes longer and costs more than a garage unit in a newer Danville build. We give you the price before we touch a panel. Bring another company’s written estimate and we’ll put our number next to it, free. That’s the Haven Standard, and it’s been our practice since 2013.

FAQs - HVAC Cleaning in Concord
Every 2 to 3 years is realistic for Concord homes on unpaved lanes or adjacent to open land east of the city. The dust load on the air handler is higher than in denser subdivisions, and by year three, most of these systems show measurable restriction at the coil. If you’re in a tract home on paved streets without wildfire smoke exposure, 3 to 5 years is more typical. Call (806) 606-6902 and we’ll help you pin down the right interval based on what’s around your property and what the camera shows.
The filter catches some of it, but not enough. During the 2018 Camp Fire, Concord’s AQI stayed elevated for days, and homeowner-grade filters, especially the 1-inch fiberglass ones in older ranch homes, pass fine PM2.5 particulate straight through. That particulate deposits on the blower motor, the evaporator coil, and the inside of the supply ducts. That’s why post-wildfire cleaning in Concord requires physical surface removal, not just a filter change. Our camera inspection shows you exactly what got through.
Because the duct system itself is frequently the contamination source. Attics in Concord routinely exceed 140°F in summer, and 50-year-old flex duct liners and fiberglass duct board break down under that heat. If we clean without inspecting, we might push fiberglass particles through a system that’s already failing. Our standard process includes a camera pass through the ducts before any cleaning starts, so we know what we’re actually dealing with. Tomas Reyes and our crew documented a 1968 ranch off Clayton Road where the return duct had collapsed in three sections. Cleaning alone would have made things worse. We replaced the failed sections, then cleaned, and the particulate fallout in the living room dropped within a week.
Yes, and the difference is measurable. Concord regularly hits 95-105°F because the Diablo Valley blocks the marine layer that cools coastal cities. When your coil is fouled with a layer of dust and smoke residue, the refrigerant can’t absorb heat as efficiently, which means longer run times, higher bills, and warmer supply air. In a coastal city with milder summers, the same coil condition might not be noticeable. In Concord, it is. A coil cleaning that removes that insulating layer is one of the highest-value services we do, and it’s always included in a full HVAC cleaning package. Get an exact price by calling (806) 606-6902.
They usually need more frequent cleaning, and they often need a different approach. A workshop or outbuilding on a rural Concord property pulls in sawdust, road dust, and whatever’s blowing off open land. Ductless mini-splits in these spaces accumulate particulate on the blower wheel fast, and the filters on these units are small. We clean them the same way we clean the main house: camera inspection first, written price, photo record after. The written estimate covers the specific building, the specific system, and the specific access situation. Call (806) 606-6902 and describe the building; we’ll give you a number before we schedule anything.
