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 $380-$620 for a whole-system service, with air quality and sanitizing work ranging from $220-$480 depending on whether mold treatment or UV installation is needed. Centreville’s 30-year-old planned-community housing stock, built during the Route 28 tech corridor boom, creates duct conditions we don’t see in newer Fairfax County subdivisions or older Arlington neighborhoods. Call (571) 526-0015 for a written estimate before any work starts.
CleanRun crews coordinate scheduling from our Washington, DC office and serve Centreville homes with background-checked, uniformed technicians operating under the H.A.V.E.N. Standard. Every job begins with a written price and ends with a Documented Photo Record of every duct run.
Why Centreville Homes Are Different
Centreville’s residential identity was built largely during the late-1980s through mid-1990s planned-community boom, most visibly in Sully Station and surrounding subdivisions tied to the Route 28 tech corridor explosion. That cohort of homes is now 30-35 years old, precisely the age at which fiberglass duct board liners delaminate and shed particulates, original mastic seals crack, and first-generation builder-grade HVAC systems show systemic duct failures.
Many early-1990s Sully Station-era colonials were built with two-story open foyer returns using unsealed stud-bay cavities rather than dedicated return ductwork. The “duct” is literally the wall cavity, which was never cleaned of construction debris at build and draws air past fiberglass batt insulation for decades. Technicians who don’t recognize this configuration miss the dirtiest part of the system entirely.
Centreville sits in the humid Piedmont transition zone adjacent to wooded parkland that sustains high summer humidity and heavy hardwood pollen loads. These conditions accelerate microbial and mold colonization inside ductwork, particularly in basement mechanical rooms typical of colonial floor plans where condensation is hardest to control.
Our Main Centreville Services
Three services account for most calls from Centreville homeowners.
Air Duct Cleaning in Centreville
Whole-system negative-pressure extraction for the fiberglass duct board and stud-bay return cavities common in Sully Station-era homes. We photograph every run before and after, including the wall cavities other crews skip. Air Duct Cleaning in Centreville includes the Documented Photo Record as standard.
Dryer Vent Cleaning in Centreville
Full-length vent run cleaning with airflow verification, critical for the 2,500-4,000 sq ft colonials with long vertical runs through multiple stories. Lint accumulation in these extended runs creates genuine fire risk that short-vent townhomes don’t face. Dryer Vent Cleaning in Centreville includes written before-and-after airflow readings.
Duct Repair & Sealing in Centreville
Mastic seal replacement, duct board liner repair, and stud-bay return encapsulation for homes where original seals have aged past 30 years. We quote sealed-system leakage testing in writing before opening any access panel. Duct Repair & Sealing in Centreville is backed by the 365-Day Done Right Promise.

BeforeAfterHVAC Cleaning in Centreville
Centreville’s 30-35 year old HVAC systems, installed during the Route 28 corridor build-out, now show evaporator coil fouling and blower wheel loading that newer equipment hasn’t had time to develop. The combination of humid Piedmont summers and heavy pollen from adjacent parkland creates a maintenance profile distinct from both coastal and mountain Virginia markets. HVAC Cleaning addresses the root causes, not just the symptoms.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, extended cooling cycles, or musty airflow when the compressor first kicks on.
What it costs in Centreville
Evaporator coil cleaning typically runs $180-$340 in Centreville, with pull-and-clean service at the higher end when the coil is embedded in an upflow air handler in a basement mechanical room.
How we do it
We remove the blower assembly for access, apply foaming cleaner to the coil face, rinse with low-pressure water, and photograph the coil condition before reassembly.
Blower Cleaning
Signs you need it
Vibration at startup, reduced airflow at registers, or dust puffing from supply vents when the fan engages.
What it costs in Centreville
Blower motor and wheel cleaning ranges $160-$280 in Centreville, with squirrel-cage wheels in larger two-zone systems at the upper end.
How we do it
We extract the blower assembly, clean the wheel vanes with compressed air and solvent, lubricate the motor per manufacturer spec, and balance the assembly before reinstalling.
What HVAC Cleaning Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$280 |
| Full HVAC system cleaning (coil + blower + cabinet) | $380-$620 |
How do I know my HVAC needs cleaning versus just the ducts?
If cooling costs spike in July or the system runs longer to reach setpoint, the coil or blower is likely fouled. Duct-only cleaning won’t restore lost heat-exchange efficiency. Call (571) 526-0015 and we’ll inspect both the ductwork and the mechanical components to identify where the restriction actually is.
Can you clean the coil without adding refrigerant?
Yes, coil cleaning is a closed-system procedure that doesn’t require refrigerant recovery. If we find a leak during inspection, we flag it in writing before any additional work. Estimates are free.
Air Quality & Sanitizing in Centreville
Centreville’s humid Piedmont climate and 30-year-old fiberglass duct board create conditions where microbial growth outpaces what we see in drier western counties or newer construction with metal ductwork. The basement mechanical rooms in Sully Station-era colonials trap condensation against duct liners, producing musty airflow that standard cleaning alone won’t resolve. Air Quality & Sanitizing targets the biological load, not just the debris.
Mold Treatment
Signs you need it
Musty odor when the system first cycles on, visible spotting on duct board interior surfaces, or aggravated allergies during humid summer months.
What it costs in Centreville
Whole-system mold treatment runs $280-$450 in Centreville, with fiberglass duct board systems requiring more extensive application than metal ductwork.
How we do it
We apply EPA-registered antimicrobial through the supply and return runs using a fogging manifold, with dwell time documented by photograph before the system is returned to service.
UV Light Installation
Signs you need it
Recurrent microbial growth after cleaning, chronic musty odor, or family members with mold-sensitive respiratory conditions.
What it costs in Centreville
UV-C lamp installation ranges $320-$480 in Centreville, with dual-lamp configurations for larger two-zone colonial systems at the upper end.
How we do it
We mount a UV-C lamp downstream of the evaporator coil with a sight-glass access port, wire to the blower relay for automatic operation, and verify irradiance with a meter.
What Air Quality & Sanitizing Costs in Centreville
| Item | Typical range in Centreville |
|---|---|
| Mold treatment (whole system) | $280-$450 |
| UV light installation | $320-$480 |
| Combined mold treatment + UV install | $520-$780 |
Is mold in ducts actually dangerous, or just unpleasant?
For most people it’s a sensitization issue, not an acute toxin exposure, but fiberglass duct board with active growth sheds both spores and degraded liner particles. We document the condition photographically and quote treatment in writing before applying anything. Call (571) 526-0015 for inspection.
How long does UV treatment take to work?
Surface biofilm begins degrading within 48 hours of lamp operation, but odor reduction typically takes 7-14 days as the system cycles. We schedule a follow-up airflow check at 30 days under the 365-Day Done Right Promise.
Brands We Service in Centreville
We carry parts and use equipment from Abatement Technologies, Rotobrush, and Guardsman on Centreville jobs, with Nikro negative-pressure extractors for whole-system cleaning. Most replacement components are stocked for same-visit completion. See our brands for full equipment specifications.
