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 Centreville, VA
HVAC cleaning in Centreville typically runs $400-$750 for a full system, while air quality and sanitizing services range from $250-$600 depending on scope. We’re CleanRun, and we dispatch crews to Centreville from our Washington, DC office - call (240) 771-1508 for a written estimate before any work starts. The late-1980s to mid-1990s housing stock here, with its original flex ductwork now at or past rated service life, makes this market different from newer Chantilly builds or older Fairfax homes.
Why Centreville Homes Are Different
Centreville’s subdivisions - Centre Ridge, London Towne, and others built during the Route 28 and I-66 corridor boom of 1985-1998 - are predominantly large two-story colonials with multi-zone forced-air systems and extensive flex duct runs through unconditioned attics. That original ductwork is now 30-plus years old. Stapled and mastic-taped connections from fast-paced tract construction frequently show separation, meaning conditioned air has been leaking into attic cavities for years.
The humid Piedmont climate drives the problem further. Summer dew points in the oppressive 70°F range push condensation inside improperly insulated or vapor-barrier-degraded attic ductwork, creating chronic microbial growth. Heavy spring oak and cedar pollen loads from the forested Bull Run corridor to the west infiltrate return systems during shoulder seasons. In Centre Ridge and London Towne, we regularly find original flex duct boot connections fully detached inside wall chases - the system conditions the attic, not the living space. Homeowners rarely know until a scope inspection reveals it.
Our Main Centreville Services
Centreville homeowners most often call us about these three services:
Air Duct Cleaning in Centreville
We clean every duct run with negative-pressure extraction, photographing the interior before and after. In Centreville’s 30-plus-year-old flex duct systems, we regularly find collapsed liner sections and detached boots that simple vacuuming misses. Our crews use Rotobrush and Nikro equipment, and every job concludes with a Documented Photo Record delivered to you. Air Duct Cleaning in Centreville includes full-system inspection as standard.
Dryer Vent Cleaning in Centreville
Dryer vent blockages in Centreville’s colonials often involve long vertical runs through two-story wall chases, with lint accumulation accelerated by the humid summers that keep moisture trapped in flex transitions. We clean the full run from appliance to termination, photograph the before and after, and verify airflow with a meter. Dryer Vent Cleaning in Centreville is quoted with a written price before we start.
Duct Repair & Sealing in Centreville
Detached boots, collapsed flex sections, and separated mastic joints are routine finds in Centreville’s original tract ductwork. We repair with code-compliant materials and seal with mastic or aerosol sealant depending on access. Every repair is photographed and priced in writing before work begins. Duct Repair & Sealing in Centreville carries the 365-Day Done Right Promise.

BeforeAfterHVAC Cleaning in Centreville
Centreville’s 30-plus-year-old forced-air systems, routed through hot humid attics, accumulate debris and microbial growth that standard filter changes never touch. HVAC Cleaning here means addressing the evaporator coil, blower assembly, and condenser as an integrated system - not running a vacuum down a few registers. We use Abatement Technologies and Honeywell-grade equipment, and every component is photographed before and after.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odors when the AC cycles on in July humidity.
What it costs in Centreville
Evaporator coil cleaning in Centreville typically runs $250-$450, with access difficulty through tight attic hatches in colonial rooflines pushing toward the higher end.
How we do it
We remove the coil cabinet cover, apply foaming cleaner to both sides of the aluminum fins, rinse with low-pressure water, and photograph the debris load before and after.
Blower Cleaning
Signs you need it
Vibration noise from the air handler, uneven heating across zones, or dust puffing from registers when the fan starts.
What it costs in Centreville
Blower motor and wheel cleaning in Centreville ranges $200-$350, with squirrel-cage wheels in older Carrier and Trane systems often requiring more labor to balance properly.
How we do it
We remove the blower assembly, clean the wheel blades and housing with compressed air and solvent, check amp draw on the motor, and reassemble with photographed documentation.
What HVAC Cleaning Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Evaporator coil cleaning | $250-$450 |
| Blower cleaning | $200-$350 |
| Full system HVAC cleaning (coil + blower + condenser) | $400-$750 |
How do I know my HVAC system needs cleaning, not just my ducts?
If your ducts are clean but rooms still heat unevenly, the evaporator coil or blower is likely clogged with debris the duct vacuum never reached. Call (240) 771-1508 and we’ll scope the components - estimates are free.
Can HVAC cleaning fix the humidity problems in my Centreville attic ducts?
Cleaning removes existing microbial growth but won’t stop new condensation; we pair it with duct sealing or insulation repair to address the moisture source. Call (240) 771-1508 for a written scope and price.
Air Quality & Sanitizing in Centreville
Centreville’s humid summers and 30-plus-year-old flex ductwork create conditions where mold and bacteria colonize inside the plenum - the main distribution box - and duct runs themselves. Air Quality & Sanitizing treats the biological load that mechanical cleaning alone doesn’t eliminate. We use EPA-registered sanitizers and, where appropriate, Aprilaire and Guardsman equipment, with every treated run photographed before and after.
Mold Treatment
Signs you need it
Visible black or gray spotting on register fins, musty odor when the system runs, or allergy symptoms that worsen at home in summer.
What it costs in Centreville
Mold treatment in Centreville ranges $300-$600 depending on linear feet of affected duct and whether the plenum requires access through a tight attic hatch.
How we do it
We apply an EPA-registered antimicrobial fog throughout the duct system, let it dwell per manufacturer spec, then run the fan to distribute and verify coverage with photographic inspection.
UV Light Installation
Signs you need it
Recurring mold after treatment, chronic musty odors, or a household member with immunocompromise who needs continuous microbial suppression.
What it costs in Centreville
UV-C light installation in Centreville runs $400-$800 including the lamp, mounting bracket, and electrical connection to the air handler.
How we do it
We mount a UV-C lamp upstream of the evaporator coil, wire to the blower circuit for synchronized operation, and photograph the installation for your job record.
What Air Quality & Sanitizing Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Mold treatment | $300-$600 |
| UV light installation | $400-$800 |
| Bacteria sanitizing (whole system) | $250-$500 |
Is mold in my ducts common in Centreville?
Yes - the combination of 30-year-old flex duct, humid attic conditions, and pollen debris creates ideal growth media; we find active mold in roughly half the Centreville systems we inspect. Call (240) 771-1508 for a scope and written price.
Will sanitizing chemicals leave residue in my air?
No - we use EPA-registered products formulated for HVAC application that break down to inert compounds; the manufacturer spec requires a dwell period followed by full system purge before we leave. Call (240) 771-1508 for product documentation.
