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
Full-system HVAC cleaning in Falls Church typically runs $380-$620 for a standard single-family home, with most jobs completed in one day. The city’s concentration of postwar Cape Cods and split-levels built between the late 1940s and mid-1960s means technicians regularly encounter galvanized steel ductwork and retrofit forced-air conversions that accumulate debris faster than modern systems. CleanRun crews coordinate dispatch from our Washington, DC office and serve Falls Church locally. Call (240) 363-3380 for a written estimate before any work starts.
Why Falls Church Homes Are Different
Falls Church sits on just 2.2 square miles, and nearly the entire city was built out in a single post-WWII wave. That means the housing stock is unusually uniform: Cape Cods, brick colonials, and split-levels from the late 1940s through the mid-1960s, many converted from gravity or steam heat to forced-air decades later. Those retrofits left undersized trunks, odd takeoff angles, and long horizontal runs that trap debris.
The city’s mature oak and maple canopy produces some of Northern Virginia’s heaviest pollen loads, and hot, humid summers averaging above 70% relative humidity push moisture into crawl-space ductwork. In older blocks near West Falls Church, we regularly find “double contamination”: fine red-clay Virginia soil infiltrating through unsealed crawl-space boots on the supply side, plus cooking grease residue drawn back from kitchen returns. That combination binds particulates to duct walls and demands mechanical agitation that air-washing alone won’t remove. A smaller wave of 2000s teardown-and-rebuild construction adds mismatched connections between original ductwork and newer additions.
Our Main Falls Church Services
Homeowners in Falls Church call us most often for these three services, each with its own dedicated local page:
Air Duct Cleaning in Falls Church
We clean the full duct network: supply and return runs, trunk lines, plenum (the main distribution box), and registers. In Falls Church’s postwar homes, we pay special attention to crawl-space boots where red-clay infiltration is common and to kitchen return lines where grease residue accumulates. Every job ends with a Documented Photo Record of every run, delivered as part of the standard job record. Air Duct Cleaning in Falls Church
Dryer Vent Cleaning in Falls Church
Dryer vent blockages are a leading cause of house fires. We remove lint buildup from the appliance connection through the exterior termination, using rotary brushes and negative-pressure extraction (suction that pulls debris out rather than pushing it deeper). In Falls Church’s older homes, we often find vents with excessive bends or degraded flex pipe that need replacement. Dryer Vent Cleaning in Falls Church
Duct Repair & Sealing in Falls Church
Disconnected seams, corroded galvanized steel, and failed flex connections leak conditioned air into crawl spaces and attics. We seal with mastic or metal-backed tape rated for duct applications, replace damaged sections, and pressure-test afterward. Falls Church’s humid crawl spaces make proper sealing critical for both efficiency and mold prevention. Duct Repair & Sealing in Falls Church

BeforeAfterHVAC Cleaning in Falls Church
HVAC cleaning in Falls Church addresses the components that move and condition air but sit outside the duct network itself: coils, blowers, condensers, and heat exchangers. The city’s postwar housing stock and heavy pollen load mean these components work harder and foul faster than in newer construction. CleanRun’s HVAC Cleaning service includes the same written upfront price and Documented Photo Record we apply to every job.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the coil, weak airflow from registers, or cooling that can’t keep up during humid July afternoons in Falls Church.
What it costs in Falls Church
Evaporator coil cleaning typically ranges $180-$340.
How we do it
We access the coil through the air handler, apply foaming cleaner, then rinse with low-pressure water and capture runoff so nothing enters the ductwork below.
Blower Cleaning
Signs you need it
Unbalanced airflow between rooms, humming or vibration from the air handler, or dust puffing from registers when the system cycles on.
What it costs in Falls Church
Blower cleaning typically ranges $140-$260.
How we do it
We remove the blower assembly, clean the squirrel cage and motor housing with compressed air and solvent, balance the fan, and photograph before reinstallation.
What HVAC Cleaning Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $140-$260 |
| Condenser cleaning | $120-$220 |
How do I know my HVAC components need cleaning, not just my ducts?
If rooms cool unevenly, the system runs longer than it used to, or you see ice on the indoor coil, the problem is likely in the HVAC unit itself, not the ducts. Call (240) 363-3380 and we’ll inspect both and put the scope in writing before starting.
Can HVAC cleaning improve my energy bills in Falls Church?
Yes, a dirty coil or blower forces the system to run longer to hit the thermostat setpoint, and in Falls Church’s humid summers that penalty adds up fast. Most homeowners see measurable improvement in cycle times after cleaning.
Air Quality & Sanitizing in Falls Church
Air quality and sanitizing in Falls Church targets the mold, bacteria, and persistent odors that thrive in the city’s humid crawl-space ductwork and postwar HVAC conversions. The combination of 70%+ summer humidity and 50-70-year-old galvanized steel creates conditions where microbial growth recurs annually rather than as a one-time problem. CleanRun’s Air Quality & Sanitizing service treats the source and documents results.
Mold Treatment
Signs you need it
Musty odor when the system runs, visible growth around registers, or allergy symptoms that spike when you’re home during humid months.
What it costs in Falls Church
Mold treatment typically ranges $280-$520.
How we do it
We apply an EPA-registered antimicrobial through the duct network using mechanical agitation, then HEPA-vacuum dead material and photograph every treated run.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, or a household member with respiratory sensitivity who needs continuous suppression at the coil surface.
What it costs in Falls Church
UV light installation typically ranges $320-$580.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp in the supply plenum, wire to the blower circuit so it runs only when air moves, and show you the installation point in the photo record.
What Air Quality & Sanitizing Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Mold treatment | $280-$520 |
| UV light installation | $320-$580 |
| Bacteria sanitizing | $240-$440 |
Is mold in my ducts a health emergency?
Most Falls Church mold is allergenic, not toxic, but it worsens asthma and allergy symptoms and spreads spores every time the blower cycles. We treat it seriously and document the before-and-after with photos.
Will UV lights eliminate all my air quality problems?
UV-C suppresses microbial growth on the coil and in the immediate plenum, but it won’t remove dust, pollen, or existing debris in duct runs; for that, you need source removal cleaning first.
Brands We Service in Falls Church
