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
Air duct cleaning in Washington, DC typically runs $380-$720 for a full residential system, with most jobs completed in a single visit and every price delivered in writing before work begins. We dispatch crews from our Washington, DC office, so Capitol Hill, Petworth, and Bloomingdale are all within our standard service radius without travel surcharges. Call (240) 318-7712 for a written estimate - we’ll ask about your home’s age, system type, and whether you’ve had recent water intrusion so the number you receive reflects actual conditions, not a teaser rate that changes once the truck arrives.
Why CleanRun Air Duct Cleaning Alexandria Is Washington’s Preferred Air Duct Cleaning Company
We’ve served Washington homeowners since 2013, and the difference shows in how we handle what other crews miss. Our Air Duct Cleaning team has documented photo records from over 52,000 homes, including thousands of DC row houses where retrofit ductwork bears no resemblance to suburban systems. Washington customers receive the same standard we apply everywhere: a written price before any panel comes off, background-checked uniformed technicians identified by name before arrival, and the 365-Day Done Right Promise backed in writing on every job.
Our Washington dispatch office coordinates scheduling directly - no third-party call centers, no “we’ll call you back with a window.” When you book, you get a named technician and a documented scope. Reviews from Washington customers consistently cite the photo record as the deciding factor: seeing the inside of their own ducts before and after, rather than taking a company’s word for “clean.”
The H.A.V.E.N. Standard governs every visit. Haven Standard Clause 1 requires written upfront pricing - no exceptions. Haven Standard Clause 3, Verified Crews, means background-checked technicians in uniform, not day laborers in unmarked vans. These aren’t marketing claims. They’re clauses you can reference if anything falls short.
Our Air Duct Cleaning Services in Washington
Residential Duct Cleaning
Washington’s housing stock demands a different approach than standard suburban work. The 1880-1930 brick row houses dominating Capitol Hill, Petworth, and Columbia Heights were built for steam or hot-water radiator heat, with no original ductwork. When forced-air HVAC was retrofitted into these narrow, three-story homes, installers crammed flex duct into closets, wall cavities, and dropped ceilings. We clean these undersized, hard-to-access runs with equipment sized for tight chases - Rotobrush and Nikro systems that fit where standard van-mounted units cannot. Every residential job includes a Documented Photo Record of every accessible duct run, delivered as part of the standard job record.
Commercial Duct Cleaning
Washington’s commercial buildings range from historic structures with modified original systems to modern mixed-use developments. We handle both, with negative-pressure extraction equipment from Abatement Technologies sized for multi-story commercial plenum systems. Our crews work around business hours where needed, and every commercial scope is priced in writing before mobilization. We maintain equipment compatibility with Honeywell and Aprilaire commercial air handlers common in DC office retrofits.
Supply Duct Cleaning
Supply ducts carry conditioned air to your registers - and in Washington’s low-lying neighborhoods, they’re where we most often find trouble. In Bloomingdale and Eckington, which sit in the Anacostia floodplain, technicians routinely find visible mold inside supply ducts even on systems only five to seven years old. The combination of high groundwater vapor, slab-on-grade or shallow-basement construction, and unsealed flex duct connections creates a near-perfect environment for fungal colonization. We photograph every supply run before touching it, so you see what we see and can make an informed decision about cleaning versus replacement.
Return Duct Cleaning
Return ducts pull air back to your air handler, and in Washington’s row houses they’re often the most neglected component. Retrofit installations frequently use joist bays or stud cavities as improvised return paths, creating collection points for debris that standard cleaning misses. Our video inspection identifies these hidden pathways before we quote, so the written price covers actual scope, not just the visible trunk line.
Full System Cleaning
A full system cleaning addresses supply ducts, return ducts, the plenum (the distribution box attached to your air handler), and accessible trunk lines. In Washington, this is particularly important for homes with layered retrofit work - older conversions in Georgetown and Capitol Hill sometimes contain two or three generations of ductwork from successive system replacements, with dead-end runs that are never cleaned and rarely discovered. Our full system scope includes investigation of these abandoned branches, documented on camera.
Video Inspection
We recommend video inspection for every Washington job, and require it for any post-flood or post-storm assessment. A flexible borescope camera shows the interior condition of each duct run - debris buildup, moisture staining, structural damage, or active microbial growth. The footage becomes part of your documented job record. For insurance claims, this visual evidence is often what distinguishes a cleanable system from one requiring replacement.

Equipment is maintained to manufacturer specifications, and technicians can identify what they’re running on your system before work starts.
Common Air Duct Cleaning Problems We See in Washington Homes
- Active mold in “new” systems. DC’s sustained summer humidity - regularly 70-80% RH for weeks - infiltrates poorly sealed retrofit ductwork and feeds mold growth year-round. We frequently find active contamination in systems only five to seven years old, especially in low-elevation neighborhoods like Bloomingdale and Eckington.
- Flex duct crammed into shared chases. Row house retrofits often stuff flex duct into spaces originally built for plumbing or electrical. These runs trap moisture that never dries, and a routine cleaning without inspection can spread spores through the entire system.
- Layered dead-end runs from successive replacements. Georgetown and Capitol Hill homes with multiple HVAC retrofits frequently contain abandoned duct sections that current contractors don’t know exist. Our camera finds them; standard cleaning ignores them.
- Post-flood systems cleaned when they should be replaced. After water intrusion, some DC ducts can be source-removed back to safe condition. Others - particularly those that sat in standing water - cannot. Documenting which is which, with moisture readings and camera evidence, is what insurers require.
Pricing for Air Duct Cleaning in Washington, DC
A typical residential duct cleaning in Washington runs $380-$520 for a standard system with 8-12 registers, accessed through normal basement or utility closet entry.

What affects your specific number: register count, system accessibility (retrofit row-house ductwork takes longer), contamination type (standard debris versus active mold requiring HEPA containment), and whether video inspection is included. We deliver one flat price per system, agreed in writing before work starts - no per-vent add-ons, no equipment surcharges, no “we found something unexpected” mid-job.

FAQs - Air Duct Cleaning in Washington
Ducts that sat in standing water generally must be replaced - source removal cannot restore saturated flex duct or waterlogged fiberglass liner to safe condition. Ducts that received only humidity exposure or minor seepage, with no structural damage, can often be addressed with Duct Repair & Sealing - Washington and cleaning under negative pressure with HEPA filtration. We make this call with a borescope camera, moisture meters, and written documentation that DC insurers accept. Call (240) 318-7712 for a post-flood assessment - estimates are free, and the documentation is included.
Suburban homes were built with purpose-designed ductwork in conditioned spaces; DC row houses had forced-air retrofitted into stairwell soffits, closets, and chases never intended for it. The access points are smaller, the runs are undersized, and debris accumulates in corners that standard equipment cannot reach. Our Rotobrush and Nikro systems are sized for these constraints, and our technicians are trained to navigate retrofit layouts without damaging adjacent finishes.
Yes - DC’s location on historically marshy land at the Potomac-Anacostia confluence produces some of the East Coast’s highest sustained relative humidity. Summer weeks at 70-80% RH push moisture through poorly sealed duct connections, and the groundwater vapor in low-elevation neighborhoods keeps basement-adjacent ductwork chronically damp. We find active mold in supply ducts at rates that simply don’t occur in drier cities or higher-elevation suburbs like Arlington or Bethesda.
Proper cleaning means source removal - dislodging debris from duct walls and extracting it under controlled negative pressure, not just blowing air through or vacuuming registers. For Washington retrofits, it also means accessing every run that carries air, including hidden branches in shared chases, and documenting the condition of each with before-and-after photography. The deliverable is a cleaned system with a photo record proving what was done.
Dryer vent cleaning addresses the exhaust duct from your clothes dryer to exterior termination, a separate system from HVAC ductwork but equally critical for fire safety. In Washington’s dense row houses, dryer vents often run long horizontal paths through shared walls with multiple bends, creating lint accumulation points that shorter suburban vents don’t face. We can add dryer vent cleaning to any duct cleaning visit, priced separately in writing before work starts.
Ready for a written estimate? Call (240) 318-7712. We’ll ask about your Washington neighborhood, your home’s age and system type, and whether you’ve noticed any musty odors or recent moisture issues. The price you receive covers your actual scope - one flat price per system, documented with before-and-after photos of every duct run we touch, backed by the 365-Day Done Right Promise.
