AfterFast, Reliable Air Duct Cleaning Across Washington
Air duct cleaning in Washington, DC typically runs $380-$680 for a full residential system, with most jobs completed in a single visit and a written price delivered before any work begins. Our crews dispatch from our Washington, DC office and serve homeowners throughout the District, from Capitol Hill to Petworth to Brookland, with the documented photo records and upfront pricing that have defined our work since 2013. Call (240) 363-3380 for a free estimate.
Washington’s housing stock is unlike anywhere else in the country. The thousands of Wardman-style row houses built between the 1910s and 1930s across neighborhoods like Petworth, Columbia Heights, and Brookland were designed for steam or hot-water radiators, not forced air. When central HVAC came later, ductwork was threaded through wall cavities, floor chases, and coal-chute voids never meant to carry it. That history lives inside your walls. Our Air Duct Cleaning team treats these systems with the specific approach they require, not the generic protocol designed for suburban tract homes.
Why CleanRun Air Duct Cleaning Washington Is Washington’s Preferred Air Duct Cleaning Company
We’ve served more than 52,000 homes since 2013, and a significant share of them have been right here in Washington. Our reputation in the District is built on one practice: we show you what we find before we quote the fix. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The license number is published on this page, not buried in a footer.
Washington customers consistently cite the same reason for choosing us back: the photo record. We photograph inside every duct run, before and after, and deliver those images as part of the standard job record. You see the 3-inch debris build-up at the first elbow. You see the crushed flex-duct patch. You see the disconnected run that was bleeding conditioned air into your basement crawl space for years.
Scheduling and dispatch are coordinated from our Washington, DC office, which means crews know the local building stock. They recognize the tight access points of a Capitol Hill row house basement. They know which Rock Creek Church Road-era homes have coal-chute voids repurposed as return chases. That local knowledge translates to faster diagnosis and a scope of work that actually matches what your system needs.
Our 365-Day Done Right Promise applies to every Washington job in writing, not as a verbal assurance. If the work is not right, we make it right.
Our Air Duct Cleaning Services in Washington
Residential Duct Cleaning
Most Washington homes we clean fall into two categories: post-war apartment buildings with original galvanized ductwork, and the far more common pre-WWII row houses with retrofit forced-air systems. In a Wardman-style home on a Petworth or Brookland street, a residential clean starts with a video inspection because we need to map where the duct runs actually go. Often they don’t go where the floor plan suggests. We use Rotobrush agitation systems combined with negative-pressure extraction, with HEPA filtration on the collection side, to remove debris without redistributing it through the house.
Commercial Duct Cleaning
Washington’s commercial building stock includes everything purpose-built to 1970s office blocks to historic structures converted for retail or restaurant use. We clean commercial duct systems in DC’s older buildings with the same documentation standard as our residential work: written scope, written price, photographed results. Many converted historic structures have ductwork added during renovation that shares the same retrofit problems as residential row houses, undersized plenums and sharp bends that create dead zones. Our crews size equipment to the system, not the other way around.
Supply Duct Cleaning
Supply ducts carry conditioned air to your rooms. In Washington row houses, these runs often pass through unconditioned basement crawl spaces or attic chases where summer humidity, regularly exceeding 70-80% in this Chesapeake Bay watershed city, creates ideal conditions for mold and microbial colonization. We clean supply ducts with agitation and negative-pressure extraction, then document the results. If the camera shows degradation inside the run, we flag it for Duct Repair & Sealing - Washington before the microbial problem returns.
Return Duct Cleaning
Return ducts pull air back to the air handler. In retrofit Washington systems, these are the runs most likely to use original coal-chute voids or steam-pipe chases as pathways. They’re also the runs most likely to be crushed, disconnected, or patched with degraded flex duct that has collapsed inside the wall cavity. Our return duct cleaning includes inspection of the full run path, not just the register-level opening. When we find a disconnected section, we document it and quote the seal, Haven Standard Clause 1: Written Price Before Work Starts.
Full System Cleaning
A full system cleaning addresses supply ducts, return ducts, the plenum (the distribution box where your main trunk connects to the air handler), and the air handler cabinet itself. In Washington’s row houses, this is often the only way to catch the full picture, debris traps in supply runs, disconnected returns, and an undersized plenum creating turbulence that deposits debris at every turn. We recommend full system cleaning for any Wardman-style or similar retrofit home that hasn’t had documented work in the past five years.
Video Inspection
Video inspection is where our Washington expertise becomes most visible. We feed a camera through the duct run and record what we find. In a retrofit system, this often reveals sharp bends, debris accumulation at elbows, and disconnected segments that a standard register-level check would miss. The video becomes part of your documented photo record. You see what we see before we quote any additional work.

Common Air Duct Cleaning Problems We See in Washington Homes
- Multi-generational debris in coal-chute voids. In Capitol Hill and Petworth row houses, technicians frequently find that duct systems were retrofitted through voids left by removed coal or oil furnaces. The debris inside may include layers of combustion-era soot and rust from original steam components sitting beneath decades of later dust accumulation, a contamination profile that requires specialized agitation and HEPA containment to remove safely.
- Crushed or disconnected flex-duct patches. Original flex-duct patches from earlier retrofits degrade over time and collapse inside wall cavities. This restricts airflow and creates pressure imbalances that force your HVAC system to work harder. A visual register-level check won’t reveal the problem; only camera inspection of the full run path will.
- Microbial growth in humid crawl-space supply runs. Washington’s summer relative humidity regularly exceeds 70-80%, among the highest of any major mid-Atlantic city. When supply ducts pass through unconditioned basement crawl spaces common in row house retrofits, condensation forms on the duct exterior and interior, creating sustained moisture that supports mold colonization inside the run.
- Undersized plenums creating dead zones. Retrofit forced-air systems in homes never designed for ductwork often have plenums that are too small for the air volume being moved. The resulting turbulence deposits debris at elbows and transitions, creating dead zones where standard cleaning approaches don’t reach the full accumulation.
Pricing for Air Duct Cleaning in Washington, DC
We publish ranges because Haven Standard Clause 1 requires a written price before any work starts, every time. Here is what air duct cleaning costs in the Washington market:
| Service | Typical Range |
|---|---|
| Residential full system cleaning (typical row house or condo) | $380-$680 |
| Video inspection with documented photo record | $150-$250 (often included in full system scope) |
| Supply duct cleaning only | $220-$380 |
| Return duct cleaning with disconnect repair/sealing | $280-$520 |
| Commercial duct system cleaning | $680-$1,800+ (scope-dependent) |
What moves a job toward the higher end: systems that haven’t been cleaned in 10+ years, documented mold or microbial growth requiring containment protocol, multiple disconnected runs needing mastic and mesh sealing, and access limitations in finished basements or sealed wall cavities. What doesn’t affect price: number of vents. We quote per system, not per register, because per-vent pricing is the industry structure that produces bait-and-switch invoices. The price we write is the price you pay. Call (240) 363-3380 for an exact quote on your Washington home, estimates are free.

FAQs - Air Duct Cleaning in Washington
Your row house was built for steam or radiator heat, not forced air. When central HVAC was retrofitted, ductwork was threaded through coal-chute voids, steam-pipe chases, and floor cavities never designed to carry it. Those pathways had decades of accumulated soot, rust, and construction debris before the first duct was installed. The camera usually shows layered contamination: combustion-era material at the bottom, decades of dust on top. Call (240) 363-3380 for a video inspection and written quote.
Yes, frequently. Original flex-duct patches from earlier retrofits degrade and collapse inside wall cavities, and runs snaked through steam-pipe voids often pull apart at joints where mastic has dried out. In a 1920s row house on Rock Creek Church Road in Petworth, our tech pulled a supply register and found the original coal-chute void had been used as a return chase, packed with soot-caked debris and a crushed flex-duct patch that had collapsed years earlier. After setting up negative pressure with HEPA filtration, we used agitation tools to break loose the layered soot, then sealed the disconnected run with mastic and mesh. The homeowner said the upstairs rooms finally stopped smelling like a basement. We document every find with before-and-after photos. Call (240) 363-3380 to schedule.
Washington sits at the confluence of the Potomac and Anacostia rivers within the Chesapeake Bay watershed, producing summer relative humidity that regularly exceeds 70-80%. When supply ducts pass through unconditioned basement crawl spaces or attic chases common in row house retrofits, that humidity creates sustained condensation inside and outside the duct, supporting mold and microbial colonization that a standard debris cleaning won’t address. We inspect for this condition during every video assessment and quote containment protocol when needed. Call (240) 363-3380 for a humidity-specific evaluation.
A video inspection maps where your duct runs actually go, which in a Wardman-style home is often not where the floor plan suggests. We’ve found supply ducts that terminate in sealed wall cavities, return chases that draw from basement crawl spaces instead of living areas, and sharp bends that create debris dead zones invisible from the register. The video becomes part of your documented photo record and lets us quote accurate scope instead of guessing. Call (240) 363-3380 to add video inspection to your service.
Yes. Washington’s converted commercial spaces, historic retail buildings, and restaurant renovations often have the same retrofit duct problems as residential row houses: undersized plenums, sharp bends, and dead zones. We scale equipment to the system size and deliver the same documented photo record and written price guarantee. Call (240) 363-3380 for a commercial scope and quote.
