AfterFast, Reliable Air Duct Cleaning Across Alexandria
Air duct cleaning in Alexandria typically runs $420-$680 for a full system on a single-family home, and older rowhouses in Old Town or Del Ray usually land at the higher end because the duct geometry is harder to reach. We’re CleanRun Air Duct Cleaning, and we’ve cleaned systems in nearly every Alexandria neighborhood, from the 18th-century brick rowhouses off King Street to the 1960s garden apartments in the West End. If you’re seeing dust accumulate on registers within days of cleaning, or your cooling bills are creeping up while airflow stays weak, the ducts themselves are the first place to look. Call (806) 606-6902 for a written, per-system price before any work begins.
Key Takeaways:
- Full-system air duct cleaning in Alexandria runs $420-$680 for most single-family homes.

- Every CleanRun job ends with a camera-verified photo record of every duct run, before and after.
- Written price delivered under Haven Standard Clause 1, always before a single panel comes off.
How Alexandria’s Historic Housing Stock Changes the Job
Alexandria is not an easy city to clean ducts in, and that’s probably why so many national franchises send a tech with a shop vac, run it for forty minutes, and leave. The reality is that the city’s housing stock spans three radically different construction eras, and each one produces its own failure modes. CleanRun has worked all of them, and we document what we find with a camera before we touch anything.
The Old Town core is the extreme case. Many 1970s-era flex ducts were routed through original 18th-century brick flue chases, a retrofit practice almost nonexistent in neighboring Arlington or Fairfax County. The duct is inaccessible for inspection, collapses under standard negative-pressure cleaning rigs, and sometimes shares a chase with an active fireplace flue. When that happens, soot infiltration into the supply air is a real finding, not a hypothetical. Cleaning there requires camera inspection and gentle negative pressure to avoid collapsing ducts that share chases with active fireplaces. A standard truck-mounted vacuum pulling full suction on that setup can implode the flex run inside a wall you can’t open without a mason.
Del Ray’s 1920s-40s craftsman bungalows are a different problem. Many still have original sheet-metal ducts lined with deteriorating fiberglass insulation, and the runs are short, rectangular, and full of 90-degree elbows that trap debris at every turn. The West End’s 1960s-70s garden apartments and tract homes often have original ductwork too, but the failure there is usually disconnected runs hidden behind drywall, not fragile flex in a brick chase.
Last week our crew worked a three-story Federal-era rowhouse on Prince Street where the return duct ran through a 1790s flue chase. We used a Rotobrush with flexible agitation tools at moderate negative pressure, then ran a camera inspection that showed soot infiltration from the adjacent fireplace flue. After source removal and sealing, supply air stayed clean on a follow-up reading. That’s the kind of documentation we leave with every Alexandria customer.
Why CleanRun Air Duct Cleaning Is Alexandria’s Preferred Air Duct Cleaning Company
We’ve been operating under the Haven Standard since 2013, and we’ve served 52,000+ homes since then, every one with a written price before work started and a documented photo record when the crew left. That’s not a marketing line. It’s Clause 1 of our operating standard, and we publish our license on every page of the site, not buried in a footer.
Our technicians are background-checked, uniformed, and identified by name before they arrive at your Alexandria home or condo. They operate under the H.A.V.E.N. Standard, and the equipment on the truck is from Rotobrush, Nikro, and Abatement Technologies, trade-recognized brands you can look up independently. No mystery rigs, no rented hardware store equipment.
Alexandria homeowners who’ve worked with us tend to mention two things: we don’t do bait pricing, and we show them the inside of their ducts before we ask for a decision. The 365-Day Done Right Promise is written into every job record. If the work isn’t right, we make it right. That’s a written guarantee, not a policy subject to manager approval.

BeforeAfterOur Air Duct Cleaning Services in Alexandria
Residential Duct Cleaning
Most Alexandria single-family homes need a full negative-pressure extraction with rotary agitation. In newer West End construction, that’s a straightforward job. In Old Town or Del Ray, we adjust the approach substantially, using flexible agitation tools at lower pressure because the ductwork runs through spaces that were never designed for forced air. We clean supply and return runs separately, and every register is removed, cleaned, and reseated. For Alexandria homeowners, we always recommend video inspection first, especially if you don’t know the duct layout or the home predates 1950.
Commercial Duct Cleaning
Alexandria’s commercial spaces run from Old Town restaurant kitchens to West End medical offices to the ground-floor retail under condominiums along Duke Street and Eisenhower Avenue. Commercial systems have longer duct runs, more registers, and frequently share air handlers across multiple tenants. CleanRun schedules commercial work around your operating hours, not the other way around. We provide the same documented photo record for commercial jobs as we do for residential, and the written price covers the full scope, every register, every run, every return.
Supply Duct Cleaning
Supply ducts are the runs carrying conditioned air from the plenum to your registers. In Alexandria’s older homes, supply ducts are where we most often find collapsed flex, disconnected joints, and debris that’s been circulating for decades. We clean supply ducts as a standalone service when the return side is clean, but in most pre-1970 Alexandria homes, supply and return are both worth doing the same day. The written price includes whichever runs you need, nothing more.
Return Duct Cleaning
Return ducts pull air from your living space back to the air handler. They run under negative pressure, so they collect a disproportionate share of dust, pet hair, and construction debris. In Old Town rowhouses, the return is often the duct routed through a former chimney flue, which means soot contamination is a real possibility. We camera-inspect every return run before and after cleaning, and we document the whole thing in your photo record.
Video Inspection
This is the service that separates real duct cleaning from vacuum noise. Before we clean anything in an Alexandria home built before 1980, we run a camera down the duct. We’re looking for collapsed runs, disconnected joints, debris blockages, and cross-contamination from fireplaces or shared stacks. You see the footage. The written scope is based on what the camera shows, not on a tech’s guess. Video inspection is included in every full-system cleaning and available as a standalone service for $95.
Full System Cleaning
This covers supply and return runs, the plenum, the air handler cabinet, the blower assembly, and all registers. In Alexandria’s humid climate, we pay particular attention to the plenum and the air handler, which are the first places microbial growth appears when condensation accumulates. We use Abatement Technologies HEPA-filtered negative air machines on full-system jobs in Alexandria, which captures the debris we dislodge rather than recirculating it through your living space.

Trusted Brands We Service in Alexandria
We stock flexible agitation tools and replacement components compatible with the systems most common in Alexandria’s housing stock, and we service all major HVAC brands. The equipment we run on your ducts is from Rotobrush, Abatement Technologies, and Guardsman, professional-grade machines you can look up. If you’re in Alexandria and you’re not sure whether your last cleaning was done by a professional rig or a shop vac, the photo record tells the story. We’ll show you the difference on the camera before we start.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Collapsed flex duct in Old Town brick chases. 1970s-era flex duct runs through 18th-century chimney spaces are fragile. A standard negative-pressure rig can implode them. We camera-inspect first and adjust pressure accordingly.
- Soot infiltration from shared fireplace flues. When a supply or return duct shares a chase with an active fireplace flue, soot can enter the air stream. We find this on Old Town rowhouses regularly, and sealing the penetration is part of the cleaning job.
- Deteriorating fiberglass duct liner in Del Ray bungalows. Original 1940s sheet-metal ducts often have fiberglass insulation on the interior that degrades and sheds particles. Cleaning removes the loose material, but we document the condition so you can plan for replacement.
- Disconnected runs in West End tract homes and garden apartments. Ducts installed in the 1960s and 70s were often joined with tape that fails over time. A disconnected run means you’re paying to condition a crawl space or wall cavity. Video inspection finds it; the photo record proves it.
How Alexandria’s River Humidity Affects Duct Cleaning
Alexandria sits directly on the Potomac River in one of the most humid corridors of the mid-Atlantic, with summer dew points regularly above 70°F. Cooling systems running through poorly vapor-sealed retrofit ductwork in older homes face chronic condensation issues that accelerate mold colonization inside ducts. The combination of long cooling seasons and wet winters means ducts rarely get a dry-out period, making microbial growth a legitimate and recurring concern rather than an upsell talking point.
What that means in practice, we document on camera. In a Del Ray craftsman with original sheet-metal ducts, condensation at the elbow joints often produces a visible film of microbial growth by August. In an Old Town rowhouse, the humidity absorbed by the masonry itself keeps duct interiors damp even when the air handler isn’t running. Cleaning the ducts removes the growth that’s already there. But the solution is sealing and insulation, and we’ll tell you that plainly rather than selling you a sanitizing fog every year.
This is the part where Air Duct Cleaning in Alexandria needs to be approached differently than in inland Fairfax County. The river changes the moisture load, and moisture is what turns ordinary dust into a biological problem. If you’re cleaning ducts in Alexandria every three to five years and still seeing microbial staining on registers, the issue is condensation, not cleaning frequency. We’ll show you the source on camera.

FAQs - Air Duct Cleaning in Alexandria
We start with a video inspection to map the runs and identify any flex duct that’s fragile, collapsed, or sharing a chase with a fireplace flue. Then we use flexible agitation tools at moderate negative pressure, specifically to avoid collapsing the duct inside an inaccessible brick chase. Standard truck-mounted vacuums at full suction are the wrong tool for this job, and they’re exactly why some Old Town homeowners end up with a collapsed run and a bigger repair bill. After cleaning, we run the camera again and document every run in your photo record. Call (806) 606-6902 for a quote specific to your rowhouse.
Alexandria’s proximity to the Potomac means summer dew points regularly exceed 70°F, and retrofit ductwork in older homes often lacks proper vapor sealing. That creates chronic condensation inside ducts, which accelerates mold colonization and turns ordinary dust into a biological contaminant. Inland Fairfax County homes see the same HVAC runtime but with lower moisture loads, so ducts there dry out between cycles. In Alexandria, they often don’t, which means microbial growth is a recurring finding, not a rare one. The fix is cleaning plus sealing, and we’ll show you the camera evidence either way. Call (806) 606-6902 to schedule an inspection.
NADCA-standard cleaning means removing the register covers, agitating the interior surfaces of every supply and return run, extracting debris under negative pressure, cleaning the plenum and air handler cabinet, and documenting the results. In a Del Ray bungalow with 1940s sheet-metal ducts, we also inspect for degraded fiberglass liner and condensation damage at the elbow joints, because those are the two most common findings in that housing stock. We use Abatement Technologies HEPA-filtered negative air equipment, so what we loosen is captured, not blown into your living room. Every job ends with a camera-verified photo record. Call (806) 606-6902 for a written price.
Yes. Shared dryer vent stacks in Alexandria garden apartments and condominiums have to be cleaned as a coordinated job, not by pushing debris into a neighbor’s run. We inspect the stack with a camera first to understand the layout and the number of branches, then clean from the exterior termination point inward, capturing lint at the source. We coordinate with building management or the condo board on scheduling, because the other units on that stack need to be informed before we start. No lint gets pushed into an adjacent run. Call (806) 606-6902 and ask about our multi-unit dryer vent stack cleaning for Alexandria buildings.
The West End 1960s tract home usually has rectangular sheet-metal ducts that were part of the original construction, routed through open joist bays and accessible wherever they run. The typical findings there are disconnected joints, degraded tape, and accumulation at the 90-degree elbows. An Old Town rowhouse is the opposite: the ducts were retrofitted into spaces never designed for forced air, routed through brick chases, plaster walls, and crawl spaces. The job takes longer, requires specialized flexible equipment, and almost always starts with a camera inspection. The price reflects the difference, and we’ll show you why in writing. Call (806) 606-6902 for a quote on your specific Alexandria property.
