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 Alexandria, VA
Whole-system HVAC cleaning in Alexandria typically runs $450-$850 for a standard single-family home, with historic row houses in Old Town often landing toward the higher end due to cramped, retrofit ductwork. We’re CleanRun Duct Repair & Cleaning, and we dispatch crews to Alexandria from our Washington, DC office. Every job starts with a written price before work begins and ends with a Documented Photo Record of every duct run. Call (240) 255-4519 for a free estimate.
Why Alexandria Homes Are Different
Alexandria’s housing stock is unlike anywhere else in Northern Virginia. Old Town and the surrounding historic districts contain pre-Civil War and early 20th-century row houses and attached townhomes that had central HVAC retrofitted into structures never designed for ductwork. These systems snake through original plaster walls and tight floor cavities, creating cramped, irregular runs that are decades overdue for cleaning.
The Potomac River compounds summer humidity, pushing moisture into imperfectly sealed ducts. That combination accelerates mold and microbial growth inside older sheet-metal and flex-duct runs. In Del Ray and Rosemont, 1920s-1950s bungalows face similar issues: undersized retrofit ductwork, poorly sealed joints, and limited modification options due to historic preservation constraints. Technicians working these neighborhoods regularly scope ducts before cleaning to locate oddly angled sections where standard vacuum hoses cannot reach decades of compacted debris.
Our Main Alexandria Services
Homeowners in Alexandria call us most often for these three services:
Air Duct Cleaning in Alexandria
We clean every duct run in Alexandria homes with negative-pressure extraction, photographing the interior before and after each run. Old Town row houses and West End garden apartments both benefit, though the technical approach differs significantly. Air Duct Cleaning in Alexandria covers our full process for historic and modern housing alike.
Dryer Vent Cleaning in Alexandria
Dryer vent blockages are common in Alexandria’s attached housing, where long vent runs through shared walls create lint accumulation points that standard homeowner tools cannot reach. We clear the full run and photograph the discharge point. Dryer Vent Cleaning in Alexandria details our scope.
Duct Repair & Sealing in Alexandria
Retrofit ductwork in Alexandria’s older neighborhoods leaks at joints and seams, wasting conditioned air into plaster cavities and between floors. We seal accessible joints and document what we cannot reach due to structural constraints. Duct Repair & Sealing in Alexandria explains our repair criteria.

AfterHVAC Cleaning in Alexandria
Alexandria’s historic housing and riverfront humidity create unique HVAC contamination patterns. Evaporator coils in Old Town row houses often harbor mold from decades of moisture infiltration through poorly sealed plenums, the central distribution box where all duct runs connect. Blower assemblies in Del Ray bungalows accumulate debris that standard filter changes cannot prevent. Our HVAC Cleaning service addresses these components directly.
Evaporator Coil Cleaning
Signs you need it
Musty odors when the AC cycles, reduced airflow from registers, or ice formation on refrigerant lines indicate coil contamination.
What it costs in Alexandria
Evaporator coil cleaning in Alexandria ranges from $280-$450, with tighter access in historic homes pushing toward the upper end.
How we do it
We remove the coil assembly when accessible, apply foaming cleaner, rinse with low-pressure water, and photograph before and after condition.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven heating or cooling between rooms, or dust visible at supply registers point to blower wheel buildup.
What it costs in Alexandria
Blower cleaning runs $220-$380 in Alexandria, depending on whether the assembly requires full removal from a tight mechanical closet.
How we do it
We extract the blower wheel, clean blades and housing with compressed air and solvent, balance the assembly, and document RPM and amp draw.
What HVAC Cleaning Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Evaporator coil cleaning | $280-$450 |
| Blower cleaning | $220-$380 |
| Full HVAC system cleaning (coil + blower + plenum) | $550-$890 |
How do I know my HVAC needs cleaning versus just my ducts?
If you smell musty odors when the system cycles, see ice on refrigerant lines, or feel weak airflow despite clean ducts, the contamination is likely in the coil or blower. Call (240) 255-4519 and we’ll scope the components to show you exactly what’s inside.
Can you clean HVAC components in tight Old Town mechanical closets?
We evaluate access during the free estimate; some historic homes require partial disassembly of surrounding cabinetry, which we document in the written scope and price before starting.
Air Quality & Sanitizing in Alexandria
Alexandria’s riverfront humidity and aging retrofit ductwork create conditions where microbial growth persists even after mechanical cleaning. Mold treatments and bacteria sanitizing target living contaminants that vacuum extraction alone cannot eliminate, particularly in flex-duct runs with internal fiberglass lining that traps moisture. Our Air Quality & Sanitizing service applies EPA-registered products with documented application protocols.
Mold Treatment
Signs you need it
Visible mold at registers, persistent musty odors after duct cleaning, or recent water intrusion events suggest active colonization inside the system.
What it costs in Alexandria
Mold treatment for a standard Alexandria system ranges from $350-$600, with severe colonization in older flex-duct requiring replacement rather than treatment.
How we do it
We apply Abatement Technologies-derived fogging agents to all interior surfaces, hold dwell time per manufacturer specification, and verify with post-treatment moisture readings.
UV Light Installation
Signs you need it
Recurring mold issues despite cleaning, family members with respiratory sensitivities, or systems located in damp basements indicate need for continuous suppression.
What it costs in Alexandria
UV light installation runs $400-$650 in Alexandria, including the lamp, mounting hardware, and electrical connection to the air handler.
How we do it
We mount a Honeywell or Aprilaire UV-C lamp downstream of the coil, wire to the blower circuit for automatic operation, and include replacement schedule documentation.
What Air Quality & Sanitizing Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Mold treatment (whole system) | $350-$600 |
| UV light installation | $400-$650 |
| Combined mold treatment + UV installation | $680-$1,050 |
Is mold treatment safe for old plaster and historic finishes?
Our application targets interior duct surfaces only; we mask surrounding areas and use controlled fogging that does not contact walls or ceilings. The written scope specifies protection measures for your home’s finishes.
How long does UV light installation take?
Most Alexandria installations finish in 2-3 hours, though access constraints in tight mechanical spaces may extend this; the written price covers completion regardless of time required.
