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
Full-system HVAC cleaning in Centreville typically runs $380-$620 for a standard single-system home, with air quality and sanitizing treatments adding $180-$340 depending on contamination level and duct accessibility. The 1980s-1990s production-built housing stock here, with its long flexible duct runs and three decades of humid Piedmont summers, creates conditions we don’t see in newer markets. We dispatch from our Washington, DC office and coordinate crews serving Centreville directly. Call (571) 520-6317 for a written estimate before any work starts.
Why Centreville Homes Are Different
Centreville’s residential footprint was built almost entirely during the late 1980s and 1990s production-builder boom. Subdivisions like Sully Station and London Towne were packed with large Colonial and split-level homes featuring extended flexible ductwork runs. That single generation of flex duct is now 25-35 years old across a dense, contiguous portion of the housing stock, hitting peak failure age simultaneously.
The builders used long, multi-bend flexible duct runs to serve wide floor plans quickly, and those flex ducts now sag, separate at joints, and trap debris after three decades of use. Attic and crawl-space duct segments are especially prone to joint separation and microbial buildup. Centreville sits in the Piedmont’s humid corridor, with prolonged high relative humidity through summer that creates condensation conditions inside poorly sealed or aging flex duct joints, accelerating mold and mildew accumulation at a rate higher than drier inland areas.
Technicians working Sully Station regularly find flex duct branches separated at collar connections inside finished walls or attic runs, a direct result of cheap clamp-only installations by volume builders. A cleaning job often surfaces an undisclosed air-loss problem the homeowner never knew existed.
Our Main Centreville Services
Three services account for most calls from Centreville homeowners, each with its own dedicated page and pricing structure.
Air Duct Cleaning in Centreville
We clean the full supply and return network with negative-pressure extraction, photographing every duct run before and after. In Centreville’s 1990s subdivisions, we regularly find separated flex duct at collar connections that was invisible until the camera went in. Air Duct Cleaning in Centreville includes the full documented photo record as standard.
Dryer Vent Cleaning in Centreville
Dryer vent blockages are common in townhome clusters where long horizontal runs exceed 25 feet. We rotary-brush the full length and verify airflow at termination. Every job gets a written price before work starts and a photo of the lint volume removed. Dryer Vent Cleaning in Centreville is priced per system, not per foot.
Duct Repair & Sealing in Centreville
When our cameras find separated collars or sagging flex duct in Sully Station attics, we can often repair without opening walls. We seal accessible joints with mastic and mechanical fasteners, then pressure-test to verify. Duct Repair & Sealing in Centreville includes before-and-after pressure readings in writing.

BeforeAfterHVAC Cleaning in Centreville
Centreville’s 25-35-year-old HVAC systems run heavily through humid summers, and the evaporator coils, blowers, and condensers in these units accumulate biofilm and debris that standard filter changes never touch. HVAC Cleaning addresses the components that actually condition your air, not just the ducts that move it. We find that production-built homes in London Towne and Sully Station often have coils clogged to the point of measurable airflow restriction, with energy bills reflecting the load.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or cooling that can’t keep up during July humidity spikes in Centreville.
What it costs in Centreville
Evaporator coil cleaning typically runs $180-$280 for accessible A-coils in Centreville’s standard attic or closet installations.
How we do it
We remove the access panel, apply foaming cleaner to the coil face, rinse with low-pressure water capture, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, uneven airflow between rooms, or a blower motor running louder than when the system was new.
What it costs in Centreville
Blower assembly cleaning typically runs $140-$220, with squirrel-cage removal and balancing included where the housing design allows.
How we do it
We remove the blower assembly, clean the squirrel cage and housing with compressed air and contact cleaner, check amp draw, and reinstall with a photo of the debris volume removed.
What HVAC Cleaning Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Evaporator coil cleaning | $180-$280 |
| Blower assembly cleaning | $140-$220 |
| Condenser coil cleaning | $120-$180 |
Can HVAC cleaning lower my energy bills in Centreville?
Yes, a clogged evaporator coil or blower can raise cooling costs 15-25% by forcing the compressor to run longer. We measure static pressure before and after to document the improvement. Call (571) 520-6317 for a written estimate.
How do I know the HVAC cleaning was actually done?
Every component cleaned is photographed before and after, delivered as part of the Documented Photo Record included on every visit. Haven Standard Clause 1 requires the written price; Clause 4 requires the photo record.
Air Quality & Sanitizing in Centreville
Centreville’s humid Piedmont summers create condensation inside aging flex duct joints, and the 25-35-year-old production housing stock shows elevated microbial activity we rarely find in drier or newer markets. Air Quality & Sanitizing treats the contamination that cleaning alone leaves behind, with application methods we document photographically.
Mold Treatment
Signs you need it
Musty odor at register startup, visible dark staining on duct interior photos, or allergy symptoms that worsen when the system runs.
What it costs in Centreville
Mold treatment for a standard single-system home typically runs $280-$450, depending on the number of affected duct runs and accessibility.
How we do it
We apply an EPA-registered antimicrobial through the full duct network using a fogging applicator, with dwell time documented, then HEPA-vacuum loose debris and photograph treated surfaces.
UV Light Installation
Signs you need it
Recurring mold after treatment, chronic musty odor, or a household member with respiratory sensitivity to airborne microbes.
What it costs in Centreville
UV-C lamp installation at the air handler typically runs $340-$520 including the lamp, housing, and electrical connection to existing low-voltage.
How we do it
We mount a UV-C lamp in the supply plenum downstream of the coil, wire to the blower circuit for automatic operation, and show the customer the installed position before closing the panel.
What Air Quality & Sanitizing Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Mold treatment (whole system) | $280-$450 |
| Bacteria sanitizing | $180-$320 |
| UV light installation | $340-$520 |
Is mold treatment safe for kids and pets?
We use EPA-registered antimicrobials applied with the system off, with dwell time and ventilation documented; occupants re-enter after the prescribed interval, typically 2-4 hours. Call (571) 520-6317 for product specification sheets.
How long does UV light last?
The lamps we install are rated for 9,000-12,000 hours of operation, typically 12-18 months in a Centreville system running year-round; we note the replacement due date on the job record.
Brands We Service in Centreville
