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-$780 for a full residential system and is always quoted in writing before any work begins. We serve homeowners from Old Town’s historic rowhouses to the mid-century ramblers of the West End, with crews dispatched daily from our Washington, DC scheduling office.
We’re familiar with Alexandria’s split personality: the 18th-century brick homes where HVAC was retrofitted decades later, and the 1950s-70s Cape Cods with original ductwork that’s never seen a brush. Both need different approaches. The Potomac’s humidity doesn’t negotiate, and neither do we when it comes to documenting what’s actually inside your ducts. Call (240) 318-7712 for a written estimate.
Why CleanRun Air Duct Cleaning Alexandria Is Alexandria’s Preferred Air Duct Cleaning Company
We’ve served more than 52,000 homes since 2013, and a significant share of them sit inside Alexandria’s city limits. Our Air Duct Cleaning in Alexandria crews know the difference between a Del Ray rambler with 1960s sheet-metal runs and a Prince Street rowhouse where the ductwork was threaded through a plaster wall cavity in the Eisenhower era.
Our reviews from Alexandria customers consistently cite two things: the photo record we deliver showing the inside of every duct run, and the written price they received before a single panel came off. Haven Standard Clause 1 - written pricing, no exceptions - applies on every job, whether it’s a garden apartment near Landmark Mall or a Federal-era home south of King Street.
Calls are answered by a live person, 24/7, and our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. Dispatch is coordinated from our metro office, with Alexandria routes scheduled daily.
Our Air Duct Cleaning Services in Alexandria
Residential Duct Cleaning
Alexandria’s housing stock demands more than a one-size-fits-all approach. In Arlandria and the West End, we find original 1950s-1970s sheet-metal ductwork that has accumulated decades of debris without ever being properly accessed. Our residential service covers the full system - supply runs, return runs, trunk lines, and plenum (the central distribution box) - using negative-pressure extraction (suction that contains loosened debris so it doesn’t escape into your living space). Every run is photographed before and after.
Commercial Duct Cleaning
Commercial buildings along Eisenhower Avenue and in the Carlyle corridor present their own challenges: larger rooftop units, extensive flex-duct networks, and occupancy schedules that limit when work can happen. We coordinate with property managers to perform full system cleaning during off-hours, delivering the same documented photo record and written scope that our residential customers receive.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. In Alexandria’s mid-century homes, these runs often terminate at floor registers in slab-on-grade construction, creating low points where moisture collects. We use agitation tools from Rotobrush and Nikro to dislodge buildup at these collection points, then extract under negative pressure. The result is documented - you’ll see the difference in the photo record.
Return Duct Cleaning
Return ducts pull air back to the air handler for reconditioning. They’re often the dirtiest part of the system, and in Alexandria they’re particularly vulnerable. The return pathways in Old Town rowhouses were frequently improvised during retrofit, running through unconditioned wall cavities where humidity from the Potomac condenses on cooler surfaces. Our Air Duct Cleaning team treats return duct cleaning as a priority, not an afterthought, using HEPA-filtered containment and professional-grade equipment from Abatement Technologies.
Full System Cleaning
This is our most comprehensive service, and it’s what most Alexandria homes actually need. Full system cleaning addresses every component - supply runs, return runs, trunk lines, plenum, and registers - in a single coordinated job. We recommend this for first-time cleanings, for homes with visible mold concerns, and for any system that hasn’t been serviced in more than five years. The price is flat per system, agreed in writing before we start.
Video Inspection
Our video inspection service uses a borescope camera to show you the interior condition of your ductwork before any cleaning decision is made. In Alexandria’s older homes, this step is essential - we’ve found collapsed flex duct, disconnected joints, and active mold colonization that changes the scope of work entirely. The inspection fee is credited toward cleaning if you proceed.

BeforeAfterTrusted Brands We Service in Alexandria
We maintain professional-grade equipment from brands you can verify independently: Rotobrush agitation systems, Nikro HEPA extractors, and Abatement Technologies negative-air machines. We’re also an Alexandria Lennox service provider. For air quality upgrades, we install Aprilaire media filters and Guardsman UV-C sanitizers where appropriate - though we’ll tell you directly when a filter upgrade makes sense and when it doesn’t. Parts for these systems are stocked for Alexandria customers, so follow-up work isn’t delayed by supply-chain waits.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Mold in retrofitted rowhouse cavities. Old Town’s historic homes had HVAC forced into walls never designed for it. The plaster-and-lathe cavities become humid from Potomac air, and fiberglass liners installed in the 1960s-80s harbor mold that rotary brushes alone won’t fix. We remove the source with agitation and HEPA extraction, then document the result.
- Undisturbed decades of debris in mid-century metal ducts. The Cape Cods and ramblers of Del Ray and Arlandria often contain original sheet-metal supply and return ducts that have never been properly cleaned. The problem isn’t just buildup - it’s that many contractors won’t attempt the job because the air handler sits in a closet too cramped for standard negative-pressure setup. We have the equipment to work in tight mechanical spaces without stirring debris into your home.
- Fogging “sanitizers” sold as solutions. Some Alexandria homeowners call us after paying for a fogging treatment that smelled nice for a week. Fogging deposits chemical on contact surfaces; it does not remove mold colonies growing on damp duct liner. The musty smell returns because the source remains. We don’t sell fogging as a standalone fix.
- Plaster damage from inexperienced contractors. Narrow chases in 19th-century brick rowhouses require flexible tools and patience. We’ve repaired damage from crews who forced standard rotary brushes through cavities too tight for them, shearing plaster keys and creating new dust pathways. Our technicians match the tool to the structure.
Pricing for Air Duct Cleaning in Alexandria, VA
We publish actual ranges because Haven Standard Clause 1 requires a written price before any work starts - not after, not “once we see it.” Here’s what air duct cleaning costs in Alexandria’s market:
| Service | Typical Range in Alexandria |
|---|---|
| Full residential system cleaning (single system, up to 12 runs) | $380-$580 |
| Full residential system cleaning (larger home, 13-20 runs) | $580-$780 |

| Return duct cleaning as standalone service | $220-$340 |
| Commercial system cleaning (per unit, varies by square footage) | $680-$1,400 |
Factors that move the price: number of duct runs, accessibility of the air handler, presence of mold requiring specialized containment, and whether the system includes hard-to-clean flex duct or fiberglass liner. What doesn’t move the price: we don’t charge per vent, we don’t add “trip fees,” and we don’t upsell fogging treatments as part of the base scope. The price we write is the price you pay.

FAQs - Air Duct Cleaning in Alexandria
Old Town’s rowhouses had central air retrofitted into 18th- and 19th-century structures with no designed mechanical space, forcing ductwork into unconditioned wall cavities where Potomac humidity condenses on cooler surfaces. Fairfax’s newer construction uses conditioned attics and proper vapor barriers that these historic homes lack. The Board of Architectural Review restrictions mean many owners cannot legally reroute or replace these failing runs, making professional cleaning and sanitizing the only permitted path to better air quality. Call (240) 318-7712 for an inspection - estimates are free.
Yes, when the technician selects tools matched to the cavity width and avoids forcing standard rotary brushes through narrow 19th-century chases. We use flexible agitation tools and camera guidance to work within the space constraints, and we document the plaster condition before starting. Haven Standard Clause 3 requires background-checked, trained technicians who understand the difference between a modern framed wall and a plaster-and-lathe historic cavity. Call (240) 318-7712 to discuss your specific property - estimates are free.
No. Fogging deposits a chemical on contact surfaces that may mask odor temporarily, but it does not remove mold colonies actively growing on damp fiberglass liner or debris buildup. The musty smell returns when the chemical dissipates because the biological source remains. We remove the source through mechanical agitation and negative-pressure extraction, then verify the result with our photo record. Call (240) 318-7712 if you’ve already paid for fogging and the odor returned - estimates are free.
MERV 8 for most older systems, MERV 11 only if the air handler can handle the static pressure drop. Alexandria’s older ductwork - especially the flex duct common in 1960s-70s construction and the retrofit cavities in Old Town - wasn’t designed for the airflow restriction of high-MERV filters. We check your system’s specifications before recommending an upgrade, and we install Aprilaire media filters where appropriate. Call (240) 318-7712 for a filter assessment with your cleaning estimate - estimates are free.
Every 3-5 years for most Alexandria homes, and every 2-3 years if you have visible mold history, pets, or occupy a historic rowhouse with retrofit ductwork. The Potomac’s tidal humidity accelerates contamination cycles compared to drier inland climates. Our photo record from your first cleaning establishes a baseline that makes future decisions objective rather than guesswork. Call (240) 318-7712 to schedule a video inspection and establish your baseline - estimates are free.
