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 Falls Church, VA
HVAC cleaning in Falls Church typically runs $320-$580 for a whole-system service, with most jobs scheduled within a week and completed in a single visit. The city’s tight 2.2-square-mile footprint is packed with post-war homes whose original heating-only ducts were retrofitted for air conditioning decades ago, leaving mismatched connections that collect debris and harbor mold in ways newer systems don’t. Call (571) 520-6317 for a written estimate before any work starts.
Why Falls Church Homes Are Different
Falls Church’s housing stock is unusually homogeneous and unusually old for the DC metro core. The post-WWII building boom filled the city with 1945-1975 cape cods, split-levels, and ranchers, many still running original galvanized ductwork or fiberglass duct-board-lined systems that have degraded over 50-plus years. These homes were built for heating only; central air was grafted on later with field-improvised connections that left gaps at every joint.
The DC metro’s humid subtropical climate pushes summer dew points above 70°F, creating condensation at imperfectly sealed supply-duct joints where cold air meets warm humid air. In Falls Church’s older, loosely joined systems, this accelerates mold colonization far faster than in drier inland markets. Technicians also regularly find fiberglass duct liner bonded to metal trunk lines in 1960s-70s homes near the I-66/Arlington Boulevard corridor that has begun to delaminate; aggressive negative pressure without first scoping the liner condition can shed fiberglass particulates into the living space. We inspect liner condition before any cleaning begins.
Our Main Falls Church Services
Most Falls Church homeowners who call us need one of these three services; each has its own dedicated page with deeper detail on local conditions and pricing.
Air Duct Cleaning in Falls Church
Full-system negative-pressure extraction of debris from every duct run, register to plenum, with a documented photo record showing the inside of each line before and after. Falls Church’s retrofitted duct systems often conceal decades of accumulation at improvised joints that newer homes simply don’t have. Air Duct Cleaning in Falls Church
Dryer Vent Cleaning in Falls Church
Complete lint removal from dryer exhaust through exterior termination, with airflow testing before and after. Older Falls Church homes frequently have longer, more convoluted vent runs through finished basements or additions that increase fire risk and drying time. Dryer Vent Cleaning in Falls Church
Duct Repair & Sealing in Falls Church
Sealing gaps, replacing degraded sections, and restoring proper airflow in systems compromised by age or retrofit work. The mismatched connections common in Falls Church’s split-levels and cape cods often leak 20-30% of conditioned air before it reaches the register. Duct Repair & Sealing in Falls Church

BeforeAfterHVAC Cleaning in Falls Church
HVAC cleaning in Falls Church addresses the accumulated burden on equipment that was never designed to handle central air through ducts built for furnace heat. The evaporator coils, blowers, and condensers in these retrofitted systems work harder and dirty faster than in homes with integrated design, and the humid climate means biological growth on coils is a routine finding, not an exception. Our HVAC Cleaning service scopes each component before quoting a written price, with every step documented photographically.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, weak airflow from registers, or musty odors when the AC cycles on.
What it costs in Falls Church
Evaporator coil cleaning typically runs $180-$340 in Falls Church, depending on accessibility and contamination level.
How we do it
We remove the access panel, inspect the coil with a borescope, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and photograph the result before reassembly.
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 Falls Church
Blower cleaning and balancing typically costs $150-$280 in Falls Church.
How we do it
We remove the blower assembly, clean the squirrel cage and motor housing with compressed air and solvent, check belt tension and bearing condition, and document RPM and amp draw before reinstalling.
What HVAC Cleaning Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil, blower, condenser) | $320-$580 |
How do I know my HVAC system needs cleaning, not just my ducts?
If rooms cool unevenly, the AC runs longer than it used to, or you smell mustiness when the compressor kicks on, the problem is likely in the HVAC components, not the duct runs alone. We scope the coil and blower during our initial inspection and show you what we find before quoting.
Can HVAC cleaning fix the humidity problems in my Falls Church home?
Cleaning restores designed airflow and drainage, which helps the system dehumidify properly, but it won’t correct an oversized unit or missing vapor barrier. We flag underlying issues we find and note them in your written report.
Air Quality & Sanitizing in Falls Church
Air quality and sanitizing in Falls Church targets the biological growth that thrives in humid conditions inside aging duct systems with imperfect seals. The same retrofitted connections that leak conditioned air also draw in attic and crawlspace moisture, creating microenvironments where mold and bacteria colonize supply ducts and blow directly into living spaces. Our Air Quality & Sanitizing service treats these contaminants with applied biocides and, where appropriate, permanent prevention equipment.
Mold Treatment
Signs you need it
Visible dark spotting on registers or duct openings, persistent musty odor that intensifies when the system runs, or family members with unexplained respiratory irritation.
What it costs in Falls Church
Whole-system mold treatment typically runs $400-$750 in Falls Church, depending on extent and accessibility.
How we do it
We collect tape-lift samples for lab identification, apply EPA-registered biocide with ULV fogging equipment to all interior surfaces, and run negative-pressure containment during treatment to prevent cross-contamination.
UV Light Installation
Signs you need it
Recurrent mold after professional cleaning, chronic allergy symptoms that improve when away from home, or a system located in a damp basement or crawlspace.
What it costs in Falls Church
UV-C lamp installation at the coil or supply plenum typically costs $280-$450 in Falls Church, including the lamp and electrical connection.
How we do it
We mount a 254-nanometer UV-C lamp with sight glass at the evaporator coil or upstream supply plenum, wire to the air-handler low-voltage circuit, and label the installation date for annual replacement scheduling.
What Air Quality & Sanitizing Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Whole-system mold treatment | $400-$750 |
| UV-C lamp installation | $280-$450 |
| Bacteria sanitizing with applied biocide | $250-$400 |
Is the biocide you use safe for children and pets?
We use EPA-registered products labeled for HVAC application, applied with the system under negative pressure and fully dried before restart; we document the product name and EPA registration number in your job record for your review.
Will UV light actually prevent mold in my old Falls Church ducts?
UV-C at the coil prevents the primary growth site that seeds the rest of the system; it does not sterilize existing duct interiors, which must be cleaned first for the lamp to be effective.

FAQs About Air Duct Cleaning in Falls Church
Standard residential duct cleaning does not require a permit in Falls Church; duct repair or modification that alters the HVAC system’s capacity or routing may require inspection through the city’s Department of Public Works. We handle permit coordination for any repair work we quote that crosses that threshold.
Most Falls Church appointments are available within 5-7 business days; we do not maintain a same-day or emergency dispatch for scheduled cleaning, as proper negative-pressure extraction requires setup time that rushed visits compromise.
Our Nikro and Rotobrush units are sized for residential access, and our technicians are trained to navigate the cramped utility closets and partial basements typical of 1950s-1970s split-levels; we note access constraints during our initial inspection and adjust our approach accordingly.
