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.

AfterAir Duct Cleaning in Ashburn, VA
HVAC cleaning in Ashburn typically runs $350-$650 for a whole-system job, with most homes in the area needing service every 3-5 years due to aging flex-duct systems and heavy seasonal pollen loads. CleanRun crews serve Ashburn from our Washington, DC office, dispatching background-checked technicians who photograph every duct run before and after work. Call (571) 487-7204 for a written price before any work starts.
Why Ashburn Homes Are Different
Ashburn sits at the epicenter of one of the largest residential build-out booms in Northern Virginia history. The overwhelming majority of housing here was built between roughly 1995 and 2012 by national tract builders who standardized on flexible ductwork in large colonial and craftsman-style homes across Ashburn Farm, Ashburn Village, Broadlands, Brambleton, and Lansdowne. Those flex-duct systems are now hitting the 20-30-year mark simultaneously, creating an unusually concentrated wave of first-time cleanings and a high rate of hidden sagging, kinking, and joint separation that only surfaces when a technician enters the system.
Loudoun County’s humid continental climate brings intense, sticky summers that push these oversized HVAC systems to short-cycle frequently, leaving moisture in duct runs and accelerating mold and dust-mite accumulation. Spring pollen from oak and maple plantings clogs ductwork faster than in urban markets. Along the Rt. 28 corridor, ongoing data center construction stirs diesel soot and construction dust that infiltrates intakes in adjacent subdivisions like Broadlands, adding a gritty particulate mix to normal biological debris.
Our Main Ashburn Services
Most Ashburn homeowners who call CleanRun are dealing with one of three issues: dirty ductwork in aging flex systems, dryer vents clogged with lint from heavy use, or duct damage that shows up once a camera goes inside. Each job starts with a written price and ends with a documented photo record.
Air Duct Cleaning in Ashburn
We clean the full supply and return network in Ashburn’s large-format homes, from the plenum (the main distribution box) through every duct run to each register. Our crews use Rotobrush and Nikro negative-pressure extraction systems, photographing the inside of every run before and after. The flex-duct common in Ashburn Farm and Ashburn Village requires gentler handling than rigid metal to avoid tearing aging liners. Air Duct Cleaning in Ashburn
Dryer Vent Cleaning in Ashburn
Dryer vent cleaning removes lint buildup from the appliance through the exterior termination, reducing fire risk and drying time. Ashburn’s larger homes often have longer vent runs through multiple stories, with more elbows that trap debris. We clean the full length with rotary brushes and verify airflow at the exterior cap.

Duct Repair & Sealing in Ashburn
Duct repair addresses the sagging, kinking, and joint separation common in Ashburn’s 20-30-year-old flex systems. We replace damaged sections, seal leaks with mastic or metal-backed tape, and restore proper airflow to rooms that have gone stale. Every repair is photographed and documented in the job record.

Before
AfterHVAC Cleaning in Ashburn
HVAC cleaning in Ashburn focuses on the components that interact most directly with the area’s aging flex-duct systems and heavy particulate load. The same oversized systems that short-cycle through humid summers coat evaporator coils and blower assemblies with biological debris and construction dust. CleanRun’s HVAC Cleaning service targets these components with professional-grade equipment, delivering a written price before work starts and a photo record when finished.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or musty odors when the AC cycles on in July.
What it costs in Ashburn
Evaporator coil cleaning typically runs $180-$320 in Ashburn, depending on accessibility and contamination level.
How we do it
We access the coil through the air handler, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling across rooms, or dust puffing from registers at startup.
What it costs in Ashburn
Blower cleaning typically runs $150-$280 in Ashburn, with variable-speed motors taking longer due to delicate balancing.
How we do it
We remove the blower assembly, clean blades and housing with compressed air and solvent, check amp draw, and reinstall with a photo record.
What HVAC Cleaning Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil + blower + housing) | $350-$650 |
How do I know my HVAC needs cleaning versus just my ducts?
If rooms cool unevenly, the air handler makes noise, or you smell mustiness at startup, the components need attention beyond duct cleaning. Call (571) 487-7204 and we’ll inspect both systems with a written quote for each.
Can HVAC cleaning fix the short-cycling in my Ashburn home?
Cleaning restores airflow and heat transfer, but short-cycling in Ashburn’s oversized systems often requires sizing analysis by an HVAC contractor. We document airflow before and after so you have data for that conversation.
Air Quality & Sanitizing in Ashburn
Air quality and sanitizing in Ashburn addresses the mold, bacteria, and heavy particulate load that builds in flex-duct systems left damp by short-cycling oversized equipment. The same pollen and construction dust that clogs ducts also feeds biological growth on wet surfaces. CleanRun’s Air Quality & Sanitizing service treats these issues with documented application methods and verifiable products.
Mold Treatment
Signs you need it
Visible mold on registers or in the plenum, musty odors that persist after cleaning, or allergy symptoms that spike when the system runs.
What it costs in Ashburn
Mold treatment typically runs $400-$750 in Ashburn, depending on the number of affected duct runs and the treatment product required.
How we do it
We apply EPA-registered antimicrobial through the duct system, fog affected areas with a pump sprayer, and document with before and after photos.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic mustiness in summer, or a household member with mold sensitivity.
What it costs in Ashburn
UV light installation typically runs $350-$600 in Ashburn, including the lamp, housing, and electrical connection to the air handler.
How we do it
We mount a Honeywell or Aprilaire UV lamp in the supply plenum, wire to the blower circuit, and show you the installation photo in your job record.
What Air Quality & Sanitizing Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Mold treatment (whole system) | $400-$750 |
| UV light installation | $350-$600 |
| Bacteria sanitizing (per application) | $250-$450 |
Is mold treatment safe for my family and pets?
We use EPA-registered products applied when the home is unoccupied, with a documented re-entry time on your written scope. The 365-Day Done Right Promise covers any re-treatment needed.
Will UV lights actually prevent mold in Ashburn’s humid summers?
UV-C lamps inhibit mold growth on illuminated surfaces like the coil and plenum, but they do not filter airborne spores; we pair them with cleaning for full protection in Ashburn’s moisture-heavy systems.
