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.

Why CleanRun Air Duct Cleaning Is Ashburn’s Preferred HVAC Cleaning Company
Ashburn homeowners research before they call. We know this because the questions we get here are different: they ask about linear footage of flex duct, whether we remove the blower wheel or just dust around it, and what a HEPA-filtered negative-pressure unit actually does. That’s the Ashburn buyer, and it’s exactly who CleanRun was built for.
We’ve served over 52,000 homes since 2013, every single one with a written price before work began and a documented photo record when the crew left. In Ashburn specifically, our technicians have walked through enough Broadlands and Brambleton mechanical rooms to know that a 4,200 sq ft house with two furnaces and a finished basement is not the same job as a 1,800 sq ft townhome off Gloucester Parkway. The duct footage is different. The coil access is different. The pricing should be different, too, and with us it is.
Tomas Reyes, who leads CleanRun, insists on a simple standard: if you can’t photograph it, you can’t claim you did it. That’s Haven Standard Clause 3: Verified Crews. Every tech is background-checked, uniformed, and identified by name before they walk through your door. And every job ends with a written scope, before-and-after photos of the inside of your duct runs, and the 365-Day Done Right Promise in writing. Not a sticker. A written guarantee.
Our HVAC Cleaning Services in Ashburn
Evaporator Coil Cleaning
In Ashburn, the evaporator coil sits inside the air handler or plenum and gets coated every season with a paste of pollen, hair, and dust that passes through the filter. In a humid Loudoun summer, that paste holds moisture against the coil fins, which reduces heat transfer and forces your compressor to run longer. A coil clean in Ashburn typically runs $190-$360 as part of a full HVAC Cleaning job. We pull the panel, document the coil condition with the camera, then clean with coil-safe foaming agents and a rinse that doesn’t soak the blower compartment.
Blower Cleaning
The blower wheel is the part most companies skip because it takes time to remove. In Ashburn’s larger homes, the blower moves far more air per hour than a smaller DC-area home, which means it collects more of the pollen that pushes Loudoun County’s air quality to “very high” levels every spring. A blower wheel caked with oak and cedar pollen costs you airflow and efficiency. Blower cleaning in Ashburn runs $140-$250, and we remove the wheel or use in-place agitation with a HEPA vacuum depending on the air handler configuration. We photograph the blades before and after.
Condenser Cleaning
Your outside condenser unit sits in Ashburn’s heat and pollen all year. We clean the coil fins, clear the debris mat that builds up under the unit, and check the line-set insulation and electrical connections while we’re there. Condenser cleaning in most Ashburn homes runs $180-$300, and it matters because a restricted condenser coil in a 95°F August heat wave is the fastest way to shorten a compressor’s life. We don’t pressure-wash the fins flat. We use low-pressure water and coil cleaner, the way the manufacturer intends.
Air Handler Cleaning
Air handler cleaning is the center of the job in Ashburn because so many units live in semi-conditioned attic spaces above the second floor. That’s where the humid summer air condenses on the cabinet walls, and where original construction dust from the 1990s build wave still circulates. Air handler cleaning runs $220-$390 in Ashburn and includes the cabinet interior, the condensate pan and drain line check, the blower compartment, and the coil compartment. We use HEPA-filtered equipment from brands like Rotobrush and Abatement Technologies, and we show you the photo record when we’re done.

BeforeAfterTrusted Brands We Service in Ashburn
Ashburn’s housing stock spans the full range: Trane and Carrier furnaces from the early Ashburn Farm build-out, Lennox and Rheem systems in Broadlands and Brambleton, and newer high-efficiency variable-speed units in the 2015-era communities near the Silver Line. We service them all. Our crews carry common parts for all major brands, so when we find a failed capacitor or a corroded flame sensor during the cleaning, we can often fix it that same visit. We don’t sell you a part you don’t need. We photograph the part, show you the reading, and give you the written price before we touch it.
Common HVAC Cleaning Problems We See in Ashburn Homes
- Original construction debris still in the branch runs. In Ashburn Farm and early Ashburn Village sections built before 1998, we regularly find drywall dust, fiberglass insulation particles, and sawdust from original construction packed into flex-duct runs. This is a specific artifact of Ashburn’s same-era build wave, uncommon in Leesburg’s older mixed-age stock.
- Kinked or partially collapsed flex duct at the joist transitions. Builder-grade flex duct in attic runs sags over time and often kinks where it passes over joists, reducing airflow so gradually that homeowners never notice until a cleaning comes with a camera inspection and reveals the restriction.
- Pollen loading from Loudoun County’s spring. Oak, cedar, and grass pollen push through return grilles in Ashburn’s open floor plans with high ceilings, building up on the evaporator coil and blower wheel. Homes along the W&OD Trail or near Broad Run see more of it, but every Ashburn neighborhood gets a seasonal load that warrants a documented clean.
- Moisture and mold-friendly conditions in attic duct runs. Ashburn’s humid summers cause condensation inside semi-conditioned attic spaces. A surface wipe-down or a fogging spray doesn’t remove the damp debris at the base of the duct wall. Source removal with negative-pressure extraction does.
Pricing for HVAC Cleaning in Ashburn, VA
HVAC cleaning in Ashburn typically runs between $380 and $820 depending on the size of the system and the number of air handlers. A 2,600 sq ft single-zone home with standard flex duct usually lands around $450-$550. A 4,800 sq ft Broadlands home with two furnaces, two coils, and a finished basement system often runs $650-$820. Evaporator coil cleaning alone costs $190-$360; blower cleaning $140-$250; condenser cleaning $180-$300; and air handler cleaning $220-$390. These are the prices we write down before any work begins, every single time. That’s Haven Standard Clause 1. We don’t bait you with a $79 coupon and then “discover” problems once the panels are off. We show you the camera feed and the written line items, and you decide.

FAQs - HVAC Cleaning in Ashburn
The earliest Ashburn Farm and Ashburn Village sections were built during a period when duct systems were not sealed or capped during construction, so drywall dust, fiberglass insulation particulate, and sawdust got into the branch runs before the first family ever moved in. Those homes are now 25-32 years old, and many have had no source removal since. Newer communities like Brambleton and the 2010s sections of Broadlands had stricter construction sequencing, so they generally have less original debris, though they still accumulate pollen and household dust. If your home is from the 1990s and has never been cleaned, the camera footage will tell the story. Call (806) 606-6902 for a documented inspection.
Yes. Loudoun County regularly reports some of the highest tree-pollen counts on the East Coast from March through May, and that pollen enters your system through the return-air grilles and packs onto the evaporator coil and blower wheel. Homes near the W&OD Trail, Broad Run, or the dense tree stands around Ashburn Lake see heavier loads. Most Ashburn homeowners benefit from a full cleaning every 3-5 years, but if anyone in the house has seasonal allergies, every 2-3 years is more appropriate. We can look at the photo record from your first cleaning and tell you what’s actually needed, not a prescribed timetable.
A fogging sanitiser sprays a mist into the ducts that settles on surfaces and kills some microbial growth for a short period. It does not remove the debris, dust, pollen, or construction material embedded in the duct walls. In Ashburn’s humid summers, that damp organic matter is exactly what feeds the microbial growth in the first place, so fogging alone leaves the root cause in place. A real cleaning uses negative-pressure extraction with HEPA filtration and agitation tools to remove the material, then we photograph the result. This is the distinction that matters in Ashburn’s semi-conditioned attic spaces. Fogging has a place as a secondary step, but it’s not a replacement for source removal.
In early Ashburn Farm sections specifically, original flex-duct runs are frequently found kinked or partially collapsed at the joist transitions where the duct bends over a roof truss. If a run is kinked to 40% of its diameter, no amount of cleaning will restore airflow through that branch. The fix is to repair or replace the damaged section first, then clean the system. In one Ashburn Farm home built in 1994, our camera inspection showed a fully kinked flex-duct run at a joist transition, with original drywall dust caked along the branch. We flagged the duct repair, then performed source removal with HEPA filtration and agitation tools; airflow at the registers improved immediately afterward. If you’re not sure whether your system needs a repair before cleaning, call (806) 606-6902 and we’ll bring the camera.
Most Ashburn detached homes range from 2,500 to over 5,000 sq ft with finished basements, multiple zones, and lengthy flex-duct branch runs. A typical job here involves more linear duct footage, more supply registers, and often two air handlers, which means a full HVAC cleaning takes 4-7 hours versus the 2-3 hours common in older, smaller DC-suburb housing. Cost scales with actual duct footage and the number of units, which is exactly how we price it. We measure and photograph everything, then give you one flat price per system before the work starts. No per-vent pricing games. Call (806) 606-6902 for a written estimate on your specific home.
