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.

AfterFast, Reliable Air Duct Cleaning Across Alexandria
Air duct cleaning in Alexandria, VA typically runs $380-$720 for a full residential system, with older homes in Old Town and Del Ray often falling at the higher end due to retrofit ductwork complexity. Most jobs are scheduled within 3-5 business days, and every appointment starts with a written price before any panel comes off. Call (240) 255-4519 for a free estimate.
We serve Alexandria from our Washington, DC dispatch office, with crews working daily in neighborhoods from Old Town to the West End. Our technicians know the difference between a 1990s townhome with standard flex-duct and a pre-Civil War row house where the duct run was snaked through original plaster walls during a mid-century HVAC conversion. That local knowledge changes what equipment we bring, how long the job takes, and what we find when we scope it first.
Why CleanRun Air Duct Cleaning Rockville Is Alexandria’s Preferred Air Duct Cleaning Company
CleanRun has held the same practice since 2013: written price before work starts, documented photo record when we leave, and the 365-Day Done Right Promise backed in writing on every job. In Alexandria, that accountability matters more than in most Northern Virginia markets because the housing stock demands it.
Our Air Duct Cleaning in Alexandria crews are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, identified by name before arrival. We do not send day laborers or subcontractors. The technician who scopes your ductwork is the one who cleans it.
Alexandria homeowners research before they call, and they should. The documented photo record we deliver - inside every duct run, before and after - lets you verify what was actually removed versus what a shop-vac and coupon promised. Our equipment roster includes Rotobrush, Nikro, and Abatement Technologies systems you can look up independently before agreeing to any price.
Our Air Duct Cleaning Services in Alexandria
Residential Duct Cleaning
Most Alexandria residential calls come from three housing types: pre-Civil War and early 20th-century row houses in Old Town, 1920s-1950s bungalows in Del Ray and Rosemont, and 1960s-70s garden apartments near Landmark. Each presents different duct configurations. The older attached homes dominate our serious calls - their retrofit ductwork is often undersized, poorly sealed at joints, and routed through historically protected structures that limit modification options. We clean what we can access and document what we cannot.
Commercial Duct Cleaning
Alexandria’s commercial base includes historic office buildings along King Street, restaurant kitchens in converted row houses, and newer medical and professional spaces in the Carlyle area. Commercial systems require negative-pressure extraction (a sealed suction method that prevents debris from escaping into occupied space) and often need after-hours scheduling to avoid disrupting business. We quote commercial jobs with the same written-upfront pricing as residential - Haven Standard Clause 1 - with scope defined by square footage, system count, and access conditions.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your registers. In Alexandria’s older homes, we regularly find supply runs that were crushed during installation or have separated at joints hidden inside plaster walls. A standard vacuum-only clean blows past these problems. Our Air Duct Cleaning process includes camera inspection of supply lines before agitation, so we know whether we’re removing surface dust or extracting a decade of compacted debris from a pinched flex-duct section.
Return Duct Cleaning
Return ducts pull air back to the air handler, and they run dirtier than supplies - they have no filter protection after the grille. In Alexandria’s humid climate, return plenums (the large collection box at the air handler) often show microbial staining where Potomac River moisture has entered through imperfect seals. We photograph these conditions and include them in the documented photo record, with remediation scope written separately if needed.
Full System Cleaning
For Alexandria homes, “full system” means every accessible supply and return duct run, the plenum, the air handler cabinet, and the registers - plus camera inspection of any run we cannot verify by direct access. In Old Town row houses, “accessible” is the operative word. Some runs are permanently sealed behind original plaster. We document those limitations in writing, with photos of the access points we used and the scope of what was cleaned.
Video Inspection
Video inspection is not an upsell in Alexandria. It is how we know what we’re pricing. The retrofit geometry of historic housing - duct runs snaked through 18th- and 19th-century walls at odd angles - creates bends and pinch points no standard vacuum hose can reach. The camera shows us crushed sections, disconnected joints, and debris compaction before we write the scope. Without it, we’re guessing, and we don’t guess.

AfterTrusted Brands We Service in Alexandria
CleanRun technicians operate professional-grade equipment from Nikro, Honeywell, and Aprilaire - brands you can verify independently before we start. We stock common fittings and replacement components for Alexandria service calls, which matters when a camera inspection reveals a disconnected joint or deteriorated flex-duct that needs addressing during the same visit. No waiting on parts shipments. The equipment is named here so you can research it; the results are documented in photos so you can see it.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Crushed or disconnected retrofit duct runs. Old Town row houses had central HVAC added decades after construction, and duct runs were forced through original plaster walls and tight floor cavities. We regularly find sections pinched against joists or separated at joints hidden inside walls - problems a vacuum-only service misses entirely.
- Moisture intrusion from Potomac River humidity. Alexandria’s riverside location compounds DC-metro summer humidity, pushing moisture into imperfectly sealed older sheet-metal and flex-duct runs. The result is accelerated mold and microbial growth that recirculates with every blower cycle if sealing isn’t addressed as part of the cleaning scope.
- Undersized ductwork in historically protected structures. Many Alexandria homes cannot be modified easily due to historic preservation requirements. Techs sometimes clean accessible sections and leave inaccessible runs untouched. Without camera inspection and written documentation, homeowners assume the whole system was serviced.
- Decades of compacted debris at inaccessible bends. The odd angles of retrofit ductwork create collection points where debris has accumulated for 20, 30, or 40 years. Standard agitation tools cannot reach these bends. We use specialized equipment under negative pressure with HEPA filtration to extract what vacuum hoses cannot touch.
Pricing for Air Duct Cleaning in Alexandria, VA
Full residential duct cleaning in Alexandria typically runs $380-$720, depending on system size, accessibility, and what the camera inspection reveals. Older homes in Old Town and Del Ray with complex retrofit ductwork usually fall in the $520-$720 range due to additional scoping time and specialized equipment needs. Standard post-1960s homes in the West End or newer townhome communities like Cameron Station typically start near the lower end.
Commercial systems are priced by scope: $0.35-$0.65 per square foot for standard office configurations, with restaurant and medical applications requiring separate quotes due to grease or contamination protocols.
Every price is written and agreed before work begins - Haven Standard Clause 1. No per-vent pricing. No coupon that triples once the truck arrives. The documented photo record is included as a standard deliverable, not an add-on.

FAQs - Air Duct Cleaning in Alexandria
Your duct runs were snaked through original 18th- and 19th-century plaster walls during a mid-century HVAC conversion, creating odd angles and inaccessible bends where decades of compacted debris collects. A standard vacuum hose cannot reach these sections, and without the camera, neither you nor the technician can verify what was actually cleaned. We scope every Old Town job before writing the scope, and we include the footage in your documented photo record. Call (240) 255-4519 to schedule.
Original sheet-metal ducts can almost always be cleaned if they are structurally intact; replacement is only necessary if the metal has corroded through or seams have failed completely. In Del Ray, we regularly clean 1920s-1950s sheet-metal systems and then perform Duct Repair & Sealing - Alexandria with mastic to prevent the moisture intrusion that causes corrosion. The camera inspection shows us which condition we’re dealing with before you commit to any work. Call (240) 255-4519 for a free evaluation.
Alexandria’s older housing stock requires more time, specialized equipment, and technical expertise than post-1960s construction with standard flex-duct and full access. Retrofit ductwork in historic homes demands camera inspection, custom agitation tools for compacted debris, and careful work around historically protected structures. The job takes longer. The equipment is different. The result is documented because it has to be. Call (240) 255-4519 and we’ll put our written price next to any competitor’s.
Yes - Alexandria’s position on the Potomac River compounds regional humidity, and moisture enters duct systems through imperfect seals in older sheet-metal and flex-duct runs. Once inside, that moisture supports microbial growth that spreads with every blower cycle. Cleaning removes existing growth; sealing the duct system prevents recurrence. We photograph any microbial conditions we find and include remediation scope in your written price if needed. Call (240) 255-4519 to inspect before summer peak.
Full system cleaning includes every accessible supply and return duct run, the plenum, the air handler cabinet, and all registers, plus camera inspection of runs we cannot directly access. In Alexandria’s older homes, “accessible” is defined by what the structure allows - some retrofit runs are permanently sealed behind original plaster, and we document those limitations in writing with photos. You receive the documented photo record of everything we reached, and a written notation of what we could not. Call (240) 255-4519 for specifics on your home.
