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.

Our Air Duct Cleaning Services in Washington

Residential Duct Cleaning
Most Washington homes we clean are late-1800s to early-1900s brick row houses in Petworth, Bloomingdale, or Eckington, retrofitted with forced-air systems in the 1970s-90s. These non-standard layouts, with flex duct run through closet chases and basement ceiling cavities, require different equipment and technique than suburban tract homes with purpose-built plenums. Our Air Duct Cleaning crews use negative-pressure extraction with HEPA filtration, sealing the system to NADCA standards so debris isn’t pushed into wall cavities during cleaning. A typical Washington residential job runs $380-$620 for a single-system home.

Commercial Duct Cleaning
Washington commercial properties, from K Street office retrofits to Capitol Hill row-house conversions, present their own challenges: multi-floor systems with mixed duct materials, fire dampers that must be reset properly, and occupancy schedules that narrow the cleaning window. We document every fire damper position before and after, photograph each duct run, and deliver a written scope record for facilities management. Commercial pricing starts at $1,200 and scales with system complexity.

Supply Duct Cleaning
Supply runs deliver conditioned air to your registers. In Washington’s retrofitted row houses, these often travel through original wall cavities or basement soffits with low spots where debris and condensate collect. We seal each supply branch under negative pressure, agitate with professional-grade tools from Rotobrush and Nikro, and verify with camera inspection. Supply-only cleaning runs $280-$450 in the Washington market.

Return Duct Cleaning
Return ducts pull air back to the blower, and in Washington’s humid climate they’re often the first place microbial growth appears. Row-house retrofits frequently use joist cavities or panned returns that were never designed as ductwork, creating gaps that draw air from wall cavities and basements. Our Return Duct Cleaning service includes sealing verification and airflow measurement at the air handler, with before-and-after photography of every accessible section. Returns-only: $240-$420.

Full System Cleaning
This is what most Washington row houses actually need. We clean the complete supply and return network, the plenum (the distribution box at your air handler), and all registers and grilles, under continuous negative pressure with HEPA filtration. The package includes a Documented Photo Record of every duct run and measured airflow at key registers to establish baseline performance. Full system: $480-$720.

Video Inspection
Our camera inspection service finds what a flashlight at the register cannot: kinked flex at floor penetrations, disconnected joints in basement ceiling drops, and biofilm colonies forming at condensate pools. We deliver the footage to you as part of the standard job record. Video inspection alone is $180-$260; it’s included at no additional charge with any full system cleaning.

Our negative-pressure extraction units are manufactured by Nikro and Guardsman, brands you can verify independently. We don’t sell equipment we can’t document. If your system includes an Aprilaire media air cleaner or a Honeywell electronic air purifier, we’ll note its condition in the written scope and photograph any recommended service.
Common Air Duct Cleaning Problems We See in Washington Homes

- Mold and biofilm in retrofitted flex duct. Washington’s position in the Potomac river basin produces summer dew points of 70-75°F and overnight humidity above 90%. In Petworth and Bloomingdale row houses, 1980s HVAC retrofits ran flex duct through original closet stacks floor-to-floor. These runs sag and kink at floor penetrations, pooling condensate that grows black biofilm within a single cooling season. The homeowner feels weak airflow and assumes the system is undersized.
- Debris accumulation in low spots of non-standard duct runs. Purpose-built duct systems have gradual slopes and access panels. Washington’s retrofitted closet-chase and basement-ceiling runs have sharp bends and inaccessible sections where debris mats form, restricting airflow and providing organic material for microbial growth.
- Disconnected joints in basement ceiling drops. Many Washington row houses have supply or return ductwork suspended in original basement spaces with connections that have loosened over decades. The system pulls conditioned air into the basement or wall cavities, wasting energy and pressurizing spaces that draw outdoor humidity.
- Fogging “sanitiser” treatments sold as mold remediation. This is not a building defect, but a service failure we see repeatedly: a technician sprays antimicrobial fog into ductwork without removing the debris mat that feeds microbial growth. The mold returns within weeks. Source removal under negative pressure is the only NADCA-recognized method.
Pricing for Air Duct Cleaning in Washington, DC
These are actual ranges for Washington’s market, based on system type and accessibility. Every job receives one flat price per system, agreed in writing before work starts.

FAQs - Air Duct Cleaning in Washington

Two factors combine uniquely in these neighborhoods: the 1980s flex-duct retrofits through closet chases create low spots and kinks at floor penetrations where condensate pools, and Washington’s tidal Potomac basin humidity produces 70-75°F summer dew points that keep those pools from drying. Drier inland cities with purpose-built duct systems don’t experience this combination. If you’re seeing musty odors or weak airflow in a Petworth or Bloomingdale row house, call (240) 255-4519 for a free written estimate and camera inspection.
No. Fogging deposits antimicrobial chemical on surfaces without removing the debris mat that feeds microbial growth. In Washington’s humid climate, the mold returns within weeks, often thicker because the moisture from fogging adds to the existing condensate problem. NADCA standards require source removal, mechanical agitation, and negative-pressure extraction. We don’t offer fogging as a standalone service, and we’ll document why in writing if a competitor recommends it. Call (240) 255-4519 for a second opinion on any written estimate.
A camera run through the full duct length finds kinked flex at floor penetrations, disconnected joints in basement ceiling drops, and biofilm colonies forming in condensate pools, none of which are visible from the register. On a Petworth row house off Georgia Avenue NW, our tech ran camera inspection through a 1980s flex duct retrofitted floor-to-floor in the original closet chase and found a kinked sag at the second-floor penetration holding condensate and black biofilm. We set the system under negative pressure with HEPA filtration, used agitation tools and source removal through the sag point, then verified with a second camera pass and measured airflow at the registers to confirm the blower motor was no longer straining against a choked run. The homeowner had been quoted $8,400 for a new HVAC system. The actual problem was a choked duct run. Call (240) 255-4519 to schedule a video inspection.
Most Washington homes benefit from full system cleaning every 3-5 years, but row houses with 1980s closet-chase retrofits should have video inspection every 2-3 years to catch sagging flex and condensate pooling before biofilm establishes. If you’ve had water intrusion, visible mold, or a major renovation, sooner is warranted. The Documented Photo Record from your last cleaning lets us compare conditions year over year. Call (240) 255-4519 to review your job history or schedule a new assessment.
Weak airflow in a retrofitted DC row house is more often a duct problem than an equipment problem. We’ve repeatedly found choked runs, disconnected basement drops, and kinked flex at floor penetrations that make the blower motor strain while little air reaches the registers. Camera inspection and airflow measurement tell the difference in about 30 minutes. If the ducts are clear and airflow is still inadequate, we’ll document that and you can take the data to an HVAC contractor. But don’t assume you need a new system until the ductwork has been verified. Call (240) 255-4519 for a free written estimate.
