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
HVAC cleaning in Ashburn typically runs $450-$850 for a whole-home system, with most jobs scheduled within a week and completed in one day. The scale of Ashburn homes, built during the 1995-2010 construction boom, means more ductwork per house than in older Northern Virginia communities. Call (571) 520-6317 for a written estimate before any work begins.
CleanRun crews coordinate dispatch from our Washington, DC office and serve Ashburn locally. We’ve documented the inside of every duct run we’ve cleaned since 2013, and that photo record goes to the customer before we pack up.
Why Ashburn Homes Are Different
Ashburn’s residential explosion between 1995 and 2010 filled planned communities like Broadlands, Brambleton, and Ashburn Farm with large colonial and craftsman-style homes now hitting the 20-30 year mark. That’s the age when original flex ductwork accumulates enough debris and degradation to demand a first professional cleaning. The sheer density of same-vintage, similarly-constructed homes all reaching this milestone simultaneously creates a concentrated demand wave unlike older Fairfax County communities or newer developments further west in Loudoun.
Most Ashburn homes run 3,000-5,000+ square feet with dual- or triple-zone HVAC systems and extensive flex duct runs through unconditioned attics. Northern Virginia’s humid summers, with dewpoints regularly in the low-to-mid 70s°F, mean condensation forms on interior duct surfaces where sagging flex runs sit in hot attic air. The mature suburban tree canopy planted during the late-1990s development boom now intensifies spring oak and fall weed pollen loads cycling through these systems. In Broadlands and Brambleton colonials built during the late-1990s rush, we regularly open return plenums and find original post-construction drywall dust and fiberglass insulation fragments still packed into flex duct elbows, recirculating for over two decades.
Our Main Ashburn Services
These are the three services Ashburn homeowners call about most. Each has its own dedicated Ashburn page with deeper detail.
Air Duct Cleaning in Ashburn
We clean the complete duct system, from return plenums (the large box where air enters the system) through every duct run (the individual pathways to each room) to the registers (the visible vents in your ceilings or walls). In Ashburn’s large homes, this means multiple air handlers, long flex runs, and multi-story returns that take real time to do properly. Every job ends with a Documented Photo Record of every run. Air Duct Cleaning in Ashburn

Dryer Vent Cleaning in Ashburn
Ashburn’s larger homes often have longer dryer vent runs through interior walls or up through multiple stories to roof terminations, creating more lint accumulation points than shorter, direct exterior vents. We clean the full run from the dryer connection to the exterior termination and photograph the before and after condition. Dryer Vent Cleaning in Ashburn

Duct Repair & Sealing in Ashburn
Ashburn’s 20-30 year old flex ductwork shows predictable failure patterns: sagging runs in attics, disconnected joints at plenum connections, and degraded insulation allowing condensation. We repair or replace damaged sections and seal leaks with mastic, then pressure-test to verify. Duct Repair & Sealing in Ashburn

Before
AfterHVAC Cleaning in Ashburn

HVAC cleaning in Ashburn addresses the full mechanical system, not just the ducts. The combination of large homes with multiple zones, original equipment now 20-30 years old, and humid attic conditions means evaporator coils clog with debris and blower assemblies accumulate dust that reduces airflow and strains components. CleanRun’s HVAC Cleaning service covers every major component with the same written-price-first, photo-documented approach we apply to ductwork.
Evaporator Coil Cleaning
Signs you need it
Ice forming on the coil, weak airflow from vents, or the system running continuously without reaching set temperature.
What it costs in Ashburn
Evaporator coil cleaning typically ranges $280-$450 in Ashburn.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Unusual vibration or noise from the air handler, visible dust puffing from vents at startup, or uneven heating and cooling across zones.
What it costs in Ashburn
Blower assembly cleaning typically ranges $240-$380 in Ashburn.
How we do it
We remove the blower motor and wheel, clean each blade and the housing with compressed air and solvent, balance the assembly, and reinstall with torque verification.
What HVAC Cleaning Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Evaporator coil cleaning | $280-$450 |
| Blower assembly cleaning | $240-$380 |
| Full HVAC system cleaning (coil + blower + housing) | $450-$850 |
How do I know my HVAC system needs cleaning, not just the ducts?
If your ducts are clean but rooms still heat or cool unevenly, or the system runs longer than it used to, the mechanical components are likely clogged with debris. Call (571) 520-6317 and we’ll inspect the coil and blower as part of our free estimate.
Can HVAC cleaning fix my high summer electric bills in Ashburn?
A dirty coil or blower forces the system to run longer to move the same air, which directly increases consumption. Cleaning restores designed airflow and can reduce runtime, though we won’t promise a specific dollar savings without seeing your system first.
Air Quality & Sanitizing in Ashburn

The same condensation that forms on flex duct interiors during July and August creates environments where mold can colonize, and the tight construction of 1990s-2000s volume-built homes can trap VOCs and odors that standard duct cleaning alone won’t address. CleanRun’s Air Quality & Sanitizing service treats these problems with documented methods and verifiable results.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible discoloration inside registers, or family members with unexplained respiratory symptoms that worsen at home.
What it costs in Ashburn
Mold treatment for duct systems typically ranges $350-$650 in Ashburn.
How we do it
We apply an EPA-registered antimicrobial through the duct system using a fogging device, treat the evaporator coil and plenum, and verify with post-treatment photos.
UV Light Installation
Signs you need it
Recurring mold or biofilm growth despite cleaning, or a home with high occupancy and limited fresh air exchange.
What it costs in Ashburn
UV-C light installation typically ranges $400-$750 in Ashburn.
How we do it
We mount a UV-C lamp in the supply plenum where it irradiates the coil and adjacent surfaces continuously, wiring it to the air handler’s 24-volt circuit for automatic operation.
What Air Quality & Sanitizing Costs in Ashburn
| Item | Typical range in Ashburn |
|---|---|
| Mold treatment (duct system) | $350-$650 |
| UV-C light installation | $400-$750 |
| Combined duct cleaning + mold treatment | $700-$1,200 |
Is mold in my ducts common in Ashburn?
Yes, the combination of humid attic conditions and 20-30 year old flex ductwork makes mold colonization more likely here than in drier climates or newer construction. We find active growth in roughly one of three Ashburn homes where we perform camera inspections.
Will UV lights eliminate all mold in my system?
UV-C light prevents mold and biofilm growth on the coil and in the immediate plenum area where it’s installed, but it won’t treat existing growth in remote duct runs. We typically recommend cleaning first, then UV for prevention.
