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.
Air Duct Cleaning in Alexandria, VA
HVAC cleaning in Alexandria typically costs $350-$650 for a complete system, with most jobs scheduled within a week. We dispatch crews from our Washington, DC office and serve Alexandria homeowners with documented photo records on every visit. Call (571) 520-6317 for a written price before any work starts.
Alexandria’s housing stock demands a different approach than standard suburban duct cleaning. The city’s 18th- and 19th-century brick row houses in Old Town, 1920s Craftsman bungalows in Del Ray, and mid-century garden apartments in the West End each present distinct duct configurations that affect how we scope, access, and clean the system. Our crews carry equipment from Rotobrush and Abatement Technologies specifically configured for these conditions.
Why Alexandria Homes Are Different
Alexandria sits in the Potomac River basin at a low elevation, giving it measurably higher ambient humidity than inland Northern Virginia suburbs. That moisture promotes faster microbial and mold colonization on duct liner surfaces, especially in cooler months when systems cycle between heating and cooling and condensation forms inside ducts. Duct cleaning here is a genuine indoor-air-quality issue, not a cosmetic one.
The Old Town district contains one of the densest concentrations of 18th- and 19th-century brick row houses in Northern Virginia, virtually all with forced-air HVAC retrofitted into building envelopes never designed for ductwork. Cramped, non-standard duct runs tucked into plaster walls and narrow chases accumulate debris faster and require access techniques unavailable in newer suburbs. Technicians regularly discover patchwork systems - 1950s sheet metal in the basement, 1980s flex duct stapled into wall cavities, mini-splits added where the original retrofit failed - making scoping essential before any cleaning begins.

Before
AfterHVAC Cleaning in Alexandria

HVAC cleaning in Alexandria requires equipment scaled for tight mechanical spaces and technicians trained to work around historic building fabric. The city’s humidity means evaporator coils and blower assemblies here develop biofilm faster than in drier inland counties, and the patchwork duct systems common in Old Town and Del Ray often conceal contaminated components upstream of the registers. We scope every system before quoting, and every HVAC Cleaning job includes a Documented Photo Record of each component cleaned.
Evaporator Coil Cleaning
Signs you need it
Ice formation on the coil, reduced airflow from registers, or musty odors when the AC cycles on indicate biofilm or debris blocking heat exchange.
What it costs in Alexandria
Evaporator coil cleaning in Alexandria typically runs $180-$320 depending on access and contamination level.
How we do it
We remove the coil assembly where accessible, apply foaming cleaner, rinse with low-pressure water, and photograph the before and after condition for the job record.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust blowing from registers immediately after filter changes point to blower wheel contamination.
What it costs in Alexandria
Blower cleaning in Alexandria typically costs $150-$280 based on blower type and access difficulty.
How we do it
We remove the blower assembly, clean the wheel and housing with compressed air and contact tools, balance the assembly, and document the work photographically.
What HVAC Cleaning Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Evaporator coil cleaning | $180-$320 |
| Blower cleaning | $150-$280 |
| Full HVAC system cleaning (coil, blower, air handler) | $350-$650 |
How do I know my HVAC system needs cleaning, not just my ducts?
If rooms heat or cool unevenly, the air handler makes new noise, or you smell must when the system cycles, the components inside the unit - not just the ducts - likely need attention. Call (571) 520-6317 and we’ll scope the system to show you exactly what’s there.
Can you clean HVAC components in Old Town’s tight mechanical closets?
Yes, our crews carry compact Rotobrush and Abatement Technologies equipment specifically for confined spaces, and we photograph every component before disassembly to document condition and access route. Written price before work starts, every time.
Air Quality & Sanitizing in Alexandria

Air quality and sanitizing in Alexandria addresses the microbial load that Potomac basin humidity deposits inside duct systems, particularly in older homes where insulation and vapor barriers were retrofitted inconsistently. The city’s row houses and garden apartments often harbor mold on duct liner where condensation collects at unsealed joints, and bacteria colonies can establish in standing water pans left by prior poor maintenance. We treat these conditions with documented application protocols and verify results photographically.
Mold Treatment
Signs you need it
Visible mold at registers, persistent musty odor when HVAC runs, or recent water intrusion in basement ductwork indicate active colonization requiring treatment.
What it costs in Alexandria
Mold treatment in Alexandria typically runs $400-$800 depending on affected duct length and accessibility.
How we do it
We apply EPA-registered antimicrobial through the duct system, treat affected liner or replace it if degraded, and photograph every treated section for the job record.
UV Light Installation
Signs you need it
Recurring mold after cleaning, chronic allergy symptoms when HVAC runs, or a home with persistent humidity above 60% suggest UV germicidal control would help.
What it costs in Alexandria
UV light installation in Alexandria typically costs $300-$550 per unit including mounting and electrical connection.
How we do it
We mount a UV-C lamp in the supply plenum upstream of the coil, wire to the air handler’s 24V circuit, and show you the installed position in your photo record.
What Air Quality & Sanitizing Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Mold treatment | $400-$800 |
| UV light installation | $300-$550 |
| Full air quality package (treatment + UV + filter upgrade) | $650-$1,100 |
Is mold in ducts common in Alexandria because of the humidity?
Yes, the Potomac basin’s higher ambient humidity combined with temperature cycling in shoulder seasons creates condensation on duct liner that supports mold growth, especially in older homes with unsealed joints. We scope first, then quote treatment based on what the camera shows.
Will UV lights actually prevent mold from coming back?
UV-C lamps inhibit mold and bacterial growth on the coil and nearby surfaces when properly positioned and maintained, but they do not replace duct cleaning or moisture control; we install them as part of a documented maintenance plan, not a standalone cure. Call (571) 520-6317 to discuss whether UV makes sense for your system.
Brands We Service in Alexandria
We stock parts and service equipment from Honeywell, Aprilaire, and Guardsman, with most common filters, UV lamps, and sanitizer applicator parts available for next-day installation in Alexandria. Our brands page lists full compatibility.
