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.
Air Duct Cleaning in Ashburn, VA
Complete HVAC cleaning in Ashburn typically runs $450-$850 for a whole-house system, with air quality and sanitizing treatments adding $200-$500 depending on the scope. We’re CleanRun, and we’ve found that Ashburn’s 1990s-2000s tract homes - built with the same fiberglass duct board and flex-duct systems - hit their first major service milestone all at once, producing a concentrated wave of deteriorating liners and debris buildup unique to this market. Our crews dispatch from our Washington, DC office and serve Ashburn with the same written-upfront pricing and documented photo records we’ve delivered since 2013. Call (240) 771-1508 for a free estimate.
Why Ashburn Homes Are Different
Ashburn’s residential explosion from the mid-1990s through the mid-2000s produced thousands of nearly identical planned-community tract homes - in neighborhoods like Ashburn Village, Broadlands, and Brambleton - built with the same builder-grade fiberglass duct board and flexible duct systems that are now 20-30 years old and hitting their first serious service milestone all at once. This concentrated wave of same-vintage, never-cleaned ductwork is unique to Ashburn’s boom-town development pattern and does not apply to older, more gradually built-out neighboring towns like Leesburg or Middleburg.
The humid Piedmont summers here drive moisture deep into those flexible branch ducts, especially in second-floor systems that fight 90-degree attic temperatures. Meanwhile, heavy pollen loads from surrounding mixed hardwood forests and former agricultural land converted to subdivisions amplify what collects inside. In tightly phased subdivisions like Broadlands, an experienced technician knows that every house on a given cul-de-sac was framed within the same 18-month window by the same production builder, often using identical duct layouts - meaning the mold pattern or collapsed flex run found in one home is almost certainly replicated in the neighbor’s attic as well.
Our Main Ashburn Services
These are the three services Ashburn homeowners call about most, each with its own dedicated page and pricing.
Air Duct Cleaning in Ashburn
We clean every duct run with negative-pressure extraction (a sealed vacuum system that pulls debris out without releasing it into your home), photograph the interior before and after, and deliver the photo record as part of the standard job file. Air Duct Cleaning in Ashburn

Dryer Vent Cleaning in Ashburn
Dryer vent blockages are a leading cause of house fires nationwide, and Ashburn’s larger homes with second-floor laundry rooms often have long, convoluted vent runs that trap lint in ways shorter basement ducts don’t. We use rotary brush systems and airflow meters to verify full clearance, and we document the before-and-after flow rate in writing. Dryer Vent Cleaning in Ashburn

Duct Repair & Sealing in Ashburn
When flex duct collapses, fiberglass duct board delaminates, or seams separate in Ashburn’s aging tract-home systems, we repair or replace the affected sections and seal with mastic (a thick, permanent adhesive) rather than tape that degrades. Every repair scope is written and priced before work begins, with photos of the damage included. Duct Repair & Sealing in Ashburn

Before
AfterHVAC Cleaning in Ashburn

Ashburn’s 1995-2012 housing stock was built with builder-grade HVAC components sized for cost, not longevity, and those evaporator coils, blowers, and condensers have now run through 20-30 humid Piedmont summers without professional cleaning. The result is a predictable pattern: restricted airflow, mold growth on wet coils, and blower motors laboring against debris buildup that standard filter changes never reach. Our HVAC Cleaning service addresses each component with equipment matched to the contamination type, and every scope is written and priced before a single panel comes off.
Evaporator Coil Cleaning
Signs you need it
Ice forming on the coil, weak airflow from registers, or musty odors when the AC first cycles on in Ashburn’s humid July afternoons.
What it costs in Ashburn
Evaporator coil cleaning in Ashburn typically ranges from $250 to $450.
How we do it
We access the coil through the plenum (the main air distribution box), apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Unusual vibration or noise from the air handler, uneven heating or cooling across rooms, or dust puffing from registers when the system starts.
What it costs in Ashburn
Blower motor and wheel cleaning in Ashburn typically ranges from $200 to $350.
How we do it
We remove the blower assembly, clean the wheel blades and housing with compressed air and solvent, balance the assembly, and reinstall with a written torque spec on the set screw.
What HVAC Cleaning Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower cleaning | $200-$350 |
| Full system HVAC cleaning (coil, blower, condenser) | $450-$850 |
How do I know my HVAC system needs cleaning, not just my ducts?
If your ducts are clean but rooms still heat or cool unevenly, or you smell musty air specifically when the compressor runs, the contamination is likely on the coil or blower, not in the duct runs. Call (240) 771-1508 and we’ll scope the components to show you exactly where the problem is.
Can HVAC cleaning fix my high summer electric bills in Ashburn?
A dirty coil or blower can raise energy use 15-25% by forcing the system to run longer to hit temperature; cleaning restores designed airflow and can bring consumption back to baseline. The photo record shows you the restriction we removed.
Air Quality & Sanitizing in Ashburn

Ashburn’s humid summers and heavy pollen loads create ideal conditions for microbial growth inside ductwork, especially in the flex-duct systems common to 1990s-2000s construction where interior liner deterioration traps moisture. Our Air Quality & Sanitizing service treats mold, bacteria, and persistent odors with EPA-registered products applied according to manufacturer protocol, and we verify results with post-treatment photos, not air-freshener masking.
Mold Treatment
Signs you need it
Visible black or green growth on register grilles, a persistent earthy smell when the system runs, or recent water intrusion in the attic or basement.
What it costs in Ashburn
Mold treatment for ductwork in Ashburn typically ranges from $400 to $800 depending on the number of affected runs.
How we do it
We apply an EPA-registered antimicrobial through the duct system under controlled mist pressure, allow proper dwell time, then extract residue and photograph every treated run.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, family members with asthma or immune sensitivity, or a system located in a damp crawl space or basement.
What it costs in Ashburn
UV-C light installation in Ashburn typically ranges from $350 to $650 including the lamp and mounting hardware.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and show you the installation point in the photo record.
What Air Quality & Sanitizing Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Mold treatment (ductwork) | $400-$800 |
| Bacteria sanitizing | $200-$400 |
| UV light installation | $350-$650 |
Is mold in my ducts common in Ashburn?
Yes - the combination of 20-30-year-old flex duct, humid summers, and pollen that traps moisture makes mold growth likely in homes that have never had professional treatment. We find it in roughly half the Ashburn homes we inspect that were built before 2005.
Will sanitizing chemicals linger in my air?
No - we use EPA-registered products with specified dwell and exhaust protocols, and we verify with post-treatment airflow testing that residue levels are below detection before we leave.
Brands We Service in Ashburn
We stock parts and service equipment from Honeywell, Aprilaire, and Abatement Technologies, with most common filters, UV lamps, and sanitizer formulations available for same-day installation. See our brands for the full equipment roster.
