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
HVAC cleaning in Alexandria, VA typically runs $380-$720 for a full system, with most jobs completed in one visit. Alexandria’s riverside humidity and three distinct housing eras - Federal-period row houses with retrofitted ductwork, mid-century Cape Cods with original sheet-metal systems, and 1980s-2000s infill - create conditions that standard suburban pricing rarely captures. Call (571) 526-0015 for a written estimate before any work starts.
Why Alexandria Homes Are Different
Alexandria sits directly on the Potomac River’s western bank, and the low-lying corridors along the George Washington Memorial Parkway and near Turkeycock Run Stream Valley Park trap ambient humidity well above what inland Northern Virginia cities experience. That moisture drives condensation inside supply ductwork and accelerates mold colonization, making duct cleaning a remediation necessity for many riverside homes.
The housing stock splits three ways. The Old Town Historic District contains hundreds of 18th- and 19th-century row houses and Federal-style homes where forced-air HVAC was retrofitted into buildings never engineered for it - ductwork snakes through original plaster walls, hand-dug crawl spaces, and tight attic chases, creating irregular geometries with debris traps and moisture pockets. No neighboring jurisdiction has this concentration of occupied colonial-era housing with grafted-on duct systems. Post-WWII Cape Cods and ramblers in Braddock Heights, Belle View, and Beverly Hills often still run on original sheet-metal duct systems with decades of accumulated debris; technicians regularly find that 1950s-60s rectangular trunk lines were run beneath later slab-on-grade additions, making sections physically inaccessible and forcing branch-only cleaning. Denser condo and townhome infill from the 1980s-2000s presents its own challenges with compact chases and shared systems.
Our Main Alexandria Services
These are the three services Alexandria homeowners call about most. Each has its own detailed Alexandria page.
Air Duct Cleaning in Alexandria
We clean supply and return duct runs, registers, and the main trunk line using negative-pressure extraction - a sealed vacuum method that pulls debris out without releasing it into your home. In Alexandria’s historic row houses, we use flexible equipment to navigate tight plaster chases and irregular retrofitted geometry. Every job ends with a Documented Photo Record of every run, delivered as part of your standard job record. Air Duct Cleaning in Alexandria
Dryer Vent Cleaning in Alexandria
Dryer vent cleaning removes lint accumulation from the transition duct, wall run, and exterior termination to restore airflow and reduce fire risk. Alexandria’s older homes often have longer vent runs through multiple stories of original construction, making thorough cleaning more involved than a straight-through suburban install. We photograph the full vent path before and after. Dryer Vent Cleaning in Alexandria
Duct Repair & Sealing in Alexandria
Duct repair addresses disconnected runs, corroded sheet metal, and failed mastic seals; sealing closes leakage points with applied materials or aerosolized sealant. Alexandria’s mid-century homes frequently show original duct insulation and mastic that requires pre-work material assessment for hazardous content. We provide a written scope and price before opening any access panel. Duct Repair & Sealing in Alexandria

BeforeAfterHVAC Cleaning in Alexandria
HVAC cleaning in Alexandria requires equipment matched to three very different housing stocks: colonial-era retrofits with flexible duct and tight chases, mid-century systems with accumulated decades of debris and potential hazardous insulation, and newer infill with compact shared chases. The persistent riverside humidity means evaporator coils and blower assemblies here work harder and foul faster than inland systems. HVAC Cleaning covers our full methodology; below is how we apply it in Alexandria.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on refrigerant lines, weak airflow from registers, or musty odor when the AC cycles on.
What it costs in Alexandria
Evaporator coil cleaning in Alexandria typically runs $180-$340.
How we do it
We access the coil through the plenum - the main air distribution box - apply foaming cleaner, rinse with low-pressure water, and photograph the coil surface before and after.
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 Alexandria
Blower cleaning in Alexandria typically runs $160-$290.
How we do it
We remove the blower assembly, clean the squirrel cage and motor housing with compressed air and solvent, balance the assembly, and reinstall with torque-verified fasteners.
What HVAC Cleaning Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower cleaning | $160-$290 |
| Full HVAC cleaning (coil + blower + plenum) | $380-$720 |
How do I know the HVAC cleaning was actually done?
Every job includes a Documented Photo Record of the coil and blower before and after, delivered with your invoice. Haven Standard Clause 1 requires the written price before work starts and the photo record when we leave.
Why does HVAC cleaning cost more in Old Town?
Historic row houses often have the air handler in a cramped attic or basement with limited access, requiring additional time for safe equipment handling. We quote that time in the written price, not add it later.
Air Quality & Sanitizing in Alexandria
Alexandria’s riverside humidity and colonial-era construction create conditions where mold colonizes supply ductwork and bacteria proliferate on wet evaporator surfaces. The same tight chases that make physical cleaning difficult also limit airflow and trap moisture, making sanitizing treatment a necessary complement to mechanical cleaning in many homes. Air Quality & Sanitizing details our full protocol; here is how we apply it locally.
Mold Treatment
Signs you need it
Visible mold around registers, persistent musty odor when the system runs, or recent water intrusion in a basement or crawl space duct run.
What it costs in Alexandria
Mold treatment in Alexandria typically runs $280-$550.
How we do it
We apply an EPA-registered fungistatic coating to affected duct surfaces using a low-pressure atomizer, with dwell time verified before the system is returned to service.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, chronic allergy symptoms that worsen when the HVAC runs, or a coil that fouls again within one season.
What it costs in Alexandria
UV light installation in Alexandria typically runs $320-$580.
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 verify irradiance at the coil surface with a meter.
What Air Quality & Sanitizing Costs in Alexandria
| Item | Typical range in Alexandria |
|---|---|
| Mold treatment | $280-$550 |
| UV light installation | $320-$580 |
| Combined mold treatment + UV install | $520-$980 |
Is mold treatment safe for my 1890s plaster?
We use low-pressure application and absorbent barriers around registers to protect surrounding plaster and trim; the fungistatic coating is formulated for porous surfaces and does not off-gas after cure.
Will UV lights work in a humid Alexandria basement?
UV-C output is unaffected by ambient humidity, but the lamp housing must be sealed against condensation; we specify marine-grade gaskets for basement and crawl space installations in riverside homes.
