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 typically runs $420-$780 for a full residential system, with most jobs completed in a single visit.

We’ve been cleaning ducts in Alexandria since 2013, and the work here is different from Fairfax or Loudoun County. The city’s historic housing stock, Potomac River humidity, and generations of retrofit HVAC create problems you won’t find in subdivisions built after 1990. Our Air Duct Cleaning team carries equipment specifically for tight access, plaster-wall chases, and the patchwork duct systems common in older neighborhoods.
Why CleanRun Air Duct Cleaning Herndon Is Alexandria’s Preferred Air Duct Cleaning Company
Alexandria homeowners research before they call. We built our process around that.
Every job starts with a written price delivered before any panel comes off - Haven Standard Clause 1. No “call for a quote.” No per-vent upsells. The price we put in writing is the price on the invoice.
Our documented photo record shows you what we found inside every duct run, before and after. In Alexandria’s competitive market, where a $79 coupon can turn into an $800 bill once the truck arrives, this matters. Our 365-Day Done Right Promise backs the work in writing, not as a policy subject to manager approval.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. They carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, brands you can verify independently.
We’ve served 52,000+ homes since 2013. Every one with a written price first, a photo record last.
Our Air Duct Cleaning Services in Alexandria
Residential Duct Cleaning
Alexandria’s housing stock spans three centuries. Colonial and Federal-style brick row houses in Old Town, 1920s Craftsman bungalows in Del Ray, 1960s garden apartments near Landmark - each generation needs a different approach. We size our negative-pressure extraction systems (vacuum collection that pulls debris out without releasing it into your home) to the duct material and layout, not a one-machine-fits-all protocol.
Commercial Duct Cleaning
Restaurants along King Street, medical offices near Inova Alexandria Hospital, and professional buildings in the Carlyle district face compliance and operational pressures residential customers don’t. We schedule around business hours, document every run for fire-insurance and health-department records, and deliver the same written-price guarantee.
Supply Duct Cleaning
Supply ducts push conditioned air to your registers. In Alexandria, these runs often travel through unconditioned spaces - basements in Old Town row houses, crawl spaces in Del Ray - where the Potomac basin’s higher humidity promotes condensation and microbial growth on duct liner. We photograph every supply run before agitation and after extraction so you can see the difference between real work and vacuum noise.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit. They’re the system’s lungs, and in Alexandria they collect what the city throws at them: pollen from the riverfront parks, brake dust from I-395 and the GW Parkway, and decades of accumulation in homes that have changed hands multiple times since 2015. Return duct cleaning here often reveals the heaviest buildup, especially in systems with undersized or poorly sealed return plenums (the main collection box connecting returns to your furnace).
Full System Cleaning
A full system cleaning addresses supply ducts, return ducts, the plenum, and accessible components of the air handler. In Alexandria’s older homes, this is where we most often find the real problems: disconnected runs, crushed flex duct, or original 1950s sheet metal with failing seams. We scope first, quote in writing, then clean - in that order.
Video Inspection
Our camera inspection maps what Alexandria’s walls actually contain. In newer suburbs, ducts follow predictable paths. In Old Town, a “simple” cleaning can turn up a 1980s flex duct stapled into a plaster wall cavity, partially collapsed, blocking airflow to two bedrooms. Video inspection finds this before we quote, not after we’ve started. The customer sees what we see. No interpretation needed.

BeforeAfterTrusted Brands We Service in Alexandria
We clean and service ductwork connected to all major HVAC brands, and we carry equipment from trade-recognized manufacturers: Rotobrush rotary brush systems for agitation in tight duct runs, Nikro negative-pressure vacuums for debris extraction, and Abatement Technologies HEPA filtration for containment. We stock common fittings and access panels for faster turnaround on Alexandria jobs, where older systems often need non-standard sizes no longer available through big-box retailers.
Common Air Duct Cleaning Problems We See in Alexandria Homes
- Patchwork systems in Old Town row houses. Original 1950s sheet metal in the basement, 1980s flex duct crammed into a second-floor wall, a mini-split added last year because the retrofit never reached the top floor. Cleaning without first mapping this mix misses disconnected or collapsed sections hidden behind plaster.
- Humidity-driven contamination. Alexandria’s low elevation in the Potomac basin means measurably higher ambient humidity than Fairfax or Loudoun. In cooler months, when systems cycle between heating and cooling, condensation forms on duct liner surfaces. Mold colonizes faster here. Duct cleaning without addressing this is cosmetic.
- Wrong access techniques. Technicians trained on suburban homes try standard ceiling panels. Alexandria’s plaster walls and narrow chases require cutting access ports or using specialized agitation tools that can navigate non-standard runs without damaging historic fabric.
- Scoping skipped entirely. A shop-vac at the register makes noise but doesn’t find the disconnected flex duct behind the wall. We camera-inspect first. Every time.
Pricing for Air Duct Cleaning in Alexandria, VA
Honest pricing for Alexandria’s market:
| Service | Typical Range |
|---|---|
| Full residential system cleaning (single HVAC) | $420-$780 |
| Supply duct cleaning only | $280-$450 |
| Return duct cleaning only | $240-$380 |
| Video inspection with written report | $180-$290 |

What moves the price: number of duct runs, accessibility (plaster walls and narrow chases take longer), condition of existing ductwork, and whether repairs or sealing are needed. Old Town row houses often land in the upper half of these ranges due to non-standard access. We deliver the written price before any work starts - Haven Standard Clause 1. No exceptions.

FAQs - Air Duct Cleaning in Alexandria
Old Town’s 18th- and 19th-century brick row houses had forced-air HVAC retrofitted into building envelopes never designed for ductwork, producing cramped, non-standard runs tucked into plaster walls and narrow chases that accumulate debris faster and are harder to clean thoroughly. Your friend’s Fairfax home likely has a modern duct system with standard access, proper sizing, and sealed joints from day one. Call (571) 520-6317 for a camera inspection and written estimate.
Yes, in most cases we use specialized agitation tools and rotary brush systems that navigate narrow chases without cutting access ports, though some 1920s-1940s bungalows require minimal, repairable openings to reach collapsed or disconnected sections. We scope first, show you the camera footage, and include any necessary access work in the written price before starting. Call (571) 520-6317 to schedule.
Rotobrush rotary brush systems for agitation, Nikro negative-pressure vacuums for debris extraction, and Abatement Technologies HEPA filtration for containment - all professional-grade tools customers can research independently. We select equipment based on your duct material and layout, not a one-machine protocol. Call (571) 520-6317 for specifics on your system.
Alexandria’s low elevation in the Potomac River basin creates measurably higher ambient humidity than inland Northern Virginia, promoting faster mold and microbial colonization on duct liner surfaces - especially in cooler months when systems cycle between heating and cooling and condensation forms inside ducts. This makes duct cleaning a genuine indoor-air-quality issue here, not a cosmetic service. Call (571) 520-6317 for a humidity assessment and written scope.
Yes, regularly - the patchwork of original 1950s sheet metal, 1980s flex duct, and recent mini-split additions means disconnected or partially collapsed runs are common, and they’re usually hidden behind plaster where a register-level cleaning won’t reach. Our crew was called to a Federal-style row house on Prince Street where camera inspection found a disconnected flex duct from a 1980s retrofit stapled into a wall cavity, blocking airflow to two bedrooms. We reconnected the run, sealed joints with mastic, and installed a properly sized takeoff; supply static pressure dropped and upstairs comfort matched the first floor. Call (571) 520-6317 for a video inspection.
