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 Washington, D.C.
Air duct cleaning in Washington, D.C. typically runs $425-$780 for a full system on a standard rowhouse, with the job completed in a single four-to-six-hour visit. The city’s narrow brick rowhouses, most built between 1890 and 1940 and retrofitted with forced-air HVAC decades later, create duct layouts that simply do not behave like suburban systems. We know those cramped chases and original wall cavities because we work in them every week. Call (806) 606-6902 and you’ll get a written price before anything else happens.
Our Air Duct Cleaning team serves every quadrant of Washington, D.C., from Capitol Hill to Chevy Chase. What sets this city apart is not just the age of the housing. It’s how the original architecture forces compromises in the duct runs, and how the Potomac-Anacostia basin’s summer humidity turns those compromises into a recurring contamination problem. We will show you the inside of every duct run before and after, because documented evidence is the only way to know the work was real.
Why CleanRun Air Duct Cleaning Is Washington, D.C.’s Preferred Air Duct Cleaning Company
Since 2013, CleanRun has completed 52,000+ homes nationwide, and in Washington, D.C. the pattern is consistent: homeowners want written documentation, not a sales pitch. Our technicians arrive background-checked and uniformed, identify themselves by name, and begin with a camera inspection of the plenum, trunk lines, and registers. Under Haven Standard Clause 1, you receive a written price before a single panel comes off. That is not a courtesy in this company. It is the operating rule.
Our standing in Washington, D.C. comes from work done in the neighborhoods that define this city. Capitol Hill, Columbia Heights, Shaw, Bloomingdale, Petworth, Adams Morgan, and Georgetown all present variations of the same challenge: aging rowhouse ductwork that was retrofitted around original plaster, brick party walls, and floor joists never designed for sheet metal. Tomas Reyes, who leads CleanRun, has made documented photo records a standard deliverable on every job since day one. That record includes the inside of every supply and return run, before and after, so you can verify what happened while we were in your home.
We also bring a Free Second Opinion on any written estimate. Bring a competitor’s quote and we will put our number next to it, in writing, with the same photo documentation. That is how a company with nothing to hide operates in a market where D.C. homeowners have learned to be skeptical.
Our Air Duct Cleaning Services in Washington, D.C.
Residential Duct Cleaning
Washington, D.C. rowhouses are the core of our residential work. In Capitol Hill and Shaw, we routinely find ducts threaded through original wall cavities that were never built for airflow. That means standard cleaning methods fail. We use negative-pressure extraction with agitation tools sized for narrow transitions, and we camera-inspect every run afterward. The typical D.C. rowhouse full-system cleaning runs $425-$680, depending on the number of stories and accessible register locations.
Commercial Duct Cleaning
Dupont Circle, Foggy Bottom, and Penn Quarter hold a heavy concentration of pre-war office buildings and New Deal-era apartment blocks. These structures have long horizontal duct runs with limited access points, and many still carry original sheet metal from the 1930s and 1940s. Our commercial work in Washington, D.C. focuses on buildings where tenant turnover and renovation history have left layered debris. We schedule commercial work around building occupancy, and we provide the same before-and-after photo record that residential customers receive.
Supply Duct Cleaning
Supply ducts carry conditioned air into your rooms, and in D.C.’s humid summers they are where condensation forms inside the metal. When cooled air stops moving through a duct that sits against an unconditioned wall cavity, moisture collects, and that moisture supports microbial growth. We clean supply runs first, then camera-inspect to verify the full interior surface. Expect supply-side cleaning as part of any full system job, typically representing about 40% of the total labor.
Return Duct Cleaning
Return ducts pull air back to the air handler, and in D.C. rowhouses they are often the dirtiest part of the system. Original returns in these homes were frequently converted from old gravity-air chases, meaning they are oversized, unsealed, and pulling dust from inside walls and floor cavities. We clean return runs with negative pressure, then photograph every linear foot. If a return is drawing air from an unconditioned space, we will document that on camera and explain what it means for your indoor air quality.

The equipment we run is not a mystery. Our crews use Rotobrush and Nikro extraction systems, Abatement Technologies HEPA filtration units, and Guardsman sanitizing products where the job calls for it. These are professional-grade tools that any D.C. homeowner can look up independently before agreeing to a price. We service HVAC systems regardless of brand, and because our Washington, D.C. metro office coordinates scheduling and dispatch locally, we keep the most commonly needed replacement filters and sanitizing supplies on hand for the systems we see most often in the District.
Common Air Duct Cleaning Problems We See in Washington, D.C. Homes
- The abandoned gravity-furnace plenum. In Capitol Hill and Bloomingdale rowhouses built for coal heat, the original octopus-style plenum, a wide sheet-metal chamber at the base of the old furnace, was often left in the basement and connected to a new air handler. It is now a 70-to-100-year-old debris reservoir feeding your modern ducts.
- Condensation-driven mold in poorly sealed supply runs. D.C. summer dew points above 70°F mean condensation forms inside supply ducts whenever the AC cycles off. In retrofitted rowhouse chases with no insulation, this is an every-summer event, not an anomaly.
- Debris accumulation from shared wall cavities. In neighborhoods where brick party walls define the structure, return ducts often draw air from inside those wall cavities. The result is faster particulate buildup than in purpose-built suburban systems.
- Non-standard duct transitions that defeat standard tools. Where retrofitters connected new sheet metal through original plaster and lathe, transitions are often tight, angled, and too narrow for off-the-shelf agitation heads. Without camera verification, the last 10-15% of the run never gets cleaned.

FAQs - Air Duct Cleaning in Washington, D.C.
We camera-inspect every supply and return run, then photograph the conditions that determine the answer. If water pooled inside a duct, or if the sheet metal shows rust-through, separated seams, or mold that has penetrated the insulation lining, replacement is the only defensible recommendation. We provide a written scope with time-stamped images, a description of what the camera showed at each access point, and a specific recommendation that an insurer can evaluate directly. You do not need to interpret anything yourself. Call (806) 606-6902 and we will schedule the inspection.
Two reasons. First, the ducts in 1890-1940 rowhouses were retrofitted into wall cavities and floor chases that were never designed for airflow, so they are rarely insulated or sealed properly. Second, Washington, D.C.’s position in the Potomac-Anacostia basin means summer dew points routinely exceed 70°F. When the AC cycles off, condensation forms inside those uninsulated supply ducts, and the moisture does not evaporate quickly in the enclosed chase. Mold follows reliably. That is why we treat mold in D.C. rowhouse ducts as a structural condition, not a cleaning upsell.
We can clean it in most cases, but it depends on what the camera shows. If the plenum is intact sheet metal, we can perform source removal with negative pressure and HEPA filtration, then camera-verify the interior. If the plenum has rusted through, or if it has accumulated water-damaged debris that keeps re-contaminating the downstream ducts, removal and replacement is the honest recommendation. In a Bloomingdale rowhouse after a summer storm flooded the basement, our techs found the original coal-era gravity plenum still connected to a modern air handler, filled with 80-year-old debris and now soaked. We performed source removal with negative pressure and HEPA filtration, then camera-inspected every supply and return run to confirm no remaining water-damaged surfaces before documenting the cleaned system for the homeowner’s insurer. We will give you the same documentation.
Yes. We shut down the system at the thermostat and the breaker before work begins. Running the fan while we clean would pull loosened debris back into the blower and across the coil. Shut-down also lets us safely remove register covers and access the plenum without air blowing through the work area. The system stays off for the duration of the job, usually four to six hours for a full rowhouse cleaning, and we confirm proper restart and airflow at every register before we leave.
Within the first hour on site. We camera-inspect the plenum and every accessible run, check for standing water inside the ductwork, and look at seam integrity and insulation condition. If the water was limited to the basement and did not rise into the supply runs leading upstairs, cleaning and sanitizing is often enough. If water entered the supply side, or if the old gravity plenum is involved, replacement is frequently required. We will give you a written determination with photos that same day. Call (806) 606-6902 and we will get a crew scheduled.
