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.

Why Falls Church Homes Are Different
Falls Church’s housing stock is dominated by 1950s-1960s post-WWII split-levels and ranch homes built during the initial Northern Virginia suburban boom, many still running their original sheet-metal ductwork after 60-70 years. Because this is one of Virginia’s smallest independent cities and property values have stayed relentlessly high, these aging systems are frequently disturbed by renovations that flood ducts with drywall dust, insulation fibers, and construction debris. The original ductwork was never replaced, only patched.
The DC metro’s humid summers hit harder here. July dew points regularly reach 70°F, and condensation builds inside ductwork routed through unconditioned crawl spaces, a standard configuration in Falls Church ranch homes. That persistent moisture feeds mold colonies standard vacuuming cannot reach. In East Falls Church and near Roosevelt Street, technicians regularly find 1960s-era ductwork embedded in or just above concrete slabs. Once moisture intrudes after heavy summer thunderstorms, these lower runs become mold incubators homeowners don’t discover until a full cleaning exposes the contamination.
Our Main Falls Church Services
Most Falls Church homeowners who call us need one of these three services:
Air Duct Cleaning in Falls Church
We clean the full duct system, from plenum (the main distribution box) through every duct run to each register, using negative-pressure extraction with Rotobrush and Nikro equipment. In Falls Church’s mid-century homes, we often find construction debris from decades of renovations packed at elbows and transitions the original installers never anticipated.

Dryer Vent Cleaning in Falls Church
Dryer vent blockages are a leading cause of house fires. We clear the full run from appliance to exterior termination, check airflow with a manometer, and photograph the before and after condition. Falls Church’s older ranch homes often have long vent runs through slab chases that sag and collect lint. Dryer Vent Cleaning in Falls Church

Duct Repair & Sealing in Falls Church
Original ductwork in Falls Church’s 1950s-1970s housing is frequently unsealed at joints, leaking conditioned air into attics and crawl spaces. We seal with mastic and metal tape, repair disconnected runs, and replace collapsed flex sections. Every repair is photographed and priced in writing before work begins.

Before
AfterHVAC Cleaning in Falls Church

Falls Church’s mid-century ranch and split-level homes were built with evaporator coils and blowers sized for an era before today’s high-efficiency standards, and many have never been professionally cleaned. The combination of 60-70 year old sheet-metal ductwork, the DC metro’s humid summers, and decades of renovation debris creates a specific contamination profile: mold on coils, dust-packed blowers, and condensate drains clogged with construction particulate. HVAC Cleaning addresses each component systematically.
Evaporator Coil Cleaning
Signs you need it
Ice forming on the coil, weak airflow from registers, or a musty smell when the AC first cycles on.
What it costs in Falls Church
Evaporator coil cleaning in Falls Church typically ranges $180-$320.
How we do it
We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Unbalanced airflow between rooms, humming from the air handler, or dust puffing from registers at startup.
What it costs in Falls Church
Blower cleaning in Falls Church typically ranges $160-$280.
How we do it
We remove the blower assembly, clean blades and housing with compressed air and solvent, balance the fan, and document RPM and amp draw.
What HVAC Cleaning Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $160-$280 |
| Full HVAC system cleaning | $380-$680 |
How do I know my HVAC needs cleaning versus just the ducts?
If you smell must when the AC cycles, see ice on the coil, or get weak airflow despite clean ducts, the blower or coil is likely contaminated. Call (240) 771-1508 and we’ll inspect both systems and put a written price to each option.
Can HVAC cleaning fix uneven cooling between rooms?
Often yes, when the cause is a dust-imbalanced blower or blocked coil rather than duct leakage. We measure airflow at each register before and after to document improvement.
Air Quality & Sanitizing in Falls Church

Falls Church’s original 1950s-1960s ductwork, combined with crawl-space moisture from humid DC summers, creates conditions where mold and bacteria colonize beyond what mechanical cleaning alone can address. The Roosevelt Street area and East Falls Church in particular see slab-embedded duct runs where storm intrusion has fed hidden contamination for years. Air Quality & Sanitizing applies antimicrobial treatment and installs preventive hardware where source removal leaves living organisms behind.
Mold Treatment
Signs you need it
Visible mold at registers, a persistent earthy smell, or recent water intrusion in crawl spaces or basements.
What it costs in Falls Church
Mold treatment in Falls Church typically ranges $220-$450.
How we do it
We apply EPA-registered antimicrobial through the full duct system, fog unsealed plenum surfaces, and treat affected insulation with Abatement Technologies products.
UV Light Installation
Signs you need it
Recurring mold after professional cleaning, or a home with chronic moisture issues in the HVAC envelope.
What it costs in Falls Church
UV light installation in Falls Church typically ranges $280-$520.
How we do it
We mount a UV-C lamp in the supply plenum, wire to the air handler’s 24V circuit, and show the customer the installation photograph in their job record.
What Air Quality & Sanitizing Costs in Falls Church
| Item | Typical range in Falls Church |
|---|---|
| Mold treatment | $220-$450 |
| UV light installation | $280-$520 |
| Full air quality package | $340-$720 |
Is mold treatment safe for kids and pets?
We use EPA-registered antimicrobials rated for HVAC application, ventilate the home for 30 minutes post-treatment, and document the product SDS in your job record. Call (240) 771-1508 to review the specific products we deploy.
Will UV lights actually prevent mold from coming back?
UV-C lamps inhibit mold growth on irradiated surfaces when properly positioned in the plenum, but they do not remove existing debris; we only install them after full source cleaning per Haven Standard Clause 1.
Brands We Service in Falls Church
We stock parts and service equipment from Honeywell, Aprilaire, and Guardsman, with most common filters, UV bulbs, and plenum access panels available without ordering delay. See our brands for the full roster.
