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.

AfterAir Duct Cleaning in Baltimore: What It Costs and How It Works Here
Air duct cleaning in Baltimore typically runs $450-$850 for a single-system rowhouse, with larger or multi-zone homes falling between $900 and $1,500. CleanRun Air Duct Cleaning writes the price before any panel comes off, so the figure you approve is the figure you pay. The reason it costs more in Baltimore than in newer sprawl cities is the housing stock itself: an estimated 70,000-100,000 rowhouses built between 1880 and 1945 were retrofitted with forced-air systems decades later, and those retrofit duct runs are non-standard, tight, and slow to clean properly.
If you’re researching Air Duct Cleaning for a home in Hampden, Highlandtown, Remington, or anywhere else in the city, call (806) 606-6902. We’ll give you a written price and a documented photo record of every run before and after.
Why CleanRun Air Duct Cleaning Is Baltimore’s Preferred Air Duct Cleaning Company
We’re an independently owned and operated company under the Haven Standard, established in 2013, and we’ve served 52,000+ homes with the same discipline: written price first, photographed record last. In Baltimore we work on the stock that dominates the city: pre-war brick rowhouses with radiator heat that was never designed for ductwork. Our technicians understand that a vertical supply run rising through an interior wall chase in a Highlandtown home is a completely different job from a suburban trunk line.
Every job is backed by the 365-Day Done Right Promise, which is a written guarantee, not a phrase on a website. We also offer a Free Second Opinion on any written estimate: bring a competitor’s number, and we’ll put our own next to it in writing. Haven Standard Clause 1 is the foundation: no job starts without a written price. Clause 3 means background-checked, uniformed technicians who identify themselves by name before arriving.
Our crews working in Baltimore carry trade-recognized equipment including Rotobrush and Nikro agitation tools paired with Abatement Technologies HEPA-filtered negative-pressure units. That matters because standard equipment cannot handle what we actually find in these duct runs.
Our Air Duct Cleaning Services in Baltimore
Residential Duct Cleaning
We clean residential forced-air systems throughout Baltimore, with a focus on the retrofitted rowhouse systems that make up the majority of the city’s housing. In homes where the air handler sits in an unfinished basement and supply runs rise two or three floors through interior chases, we start with a camera inspection before any agitation begins. That inspection shows exactly where debris has collected, and the after-photo shows it gone.
Commercial Duct Cleaning
Commercial work in Baltimore includes apartment buildings, converted rowhouse offices, and small retail spaces, many with shared or stacked duct infrastructure. Jobs are priced per system with a written scope before work starts, and the photo record includes every accessible run, not a sample. Scheduling is coordinated from our Baltimore office, and all calls are answered by a live person, 24/7.
Supply Duct Cleaning
Supply ducts deliver conditioned air from the air handler to each room. In Baltimore rowhouses, these are frequently long vertical runs squeezed through party-wall soffits or wall cavities, often with sharp 90-degree bends never seen in new construction. We clean them with agitation tools sized for those bends and negative-pressure extraction that captures what the agitation knocks loose. The before-and-after camera record proves the debris at the first elbow is gone.
Return Duct Cleaning
Return ducts pull air back to the system, and in older Baltimore homes they’re often the dirtiest part of the loop. Returns in retrofitted rowhouses are sometimes no more than a wall chase with a grille, pulling years of dust, pet dander, and sometimes mold from the basement and lower floors. We clean full return runs, not just the visible register area, and document the interior condition at both ends.
Full System Cleaning and Video Inspection
A full system cleaning covers supply runs, return runs, the plenum, air handler cabinet, and accessible registers, all cleaned as one job with one written price. Video inspection is standard on every job we do in Baltimore, not an upsell. The camera shows what’s inside before we touch it and confirms it’s clean when we’re done.

BeforeAfterTrusted Brands We Service in Baltimore
The equipment matters because Baltimore’s retrofit duct runs punish weak tools. We use Rotobrush and Nikro agitation systems and Abatement Technologies HEPA-filtered negative-air machines on jobs throughout the city. We also service and clean duct systems that include Honeywell and Aprilaire filtration components. Our Baltimore office carries common parts and filters locally, and for duct repair or sealing work we use Guardsman products. If a component needs replacement, the brand is on the written scope before any work proceeds.
Common Air Duct Cleaning Problems We See in Baltimore Homes
- Kinked 90-degree bends in rowhouse soffits. Standard rotary brushes cannot navigate the tight turns created when ductwork was retrofitted through party-wall cavities. Left unaddressed, debris wedged at those bends re-contaminates the system within months. We use agitation tools built for tight-radius bends and verify with the camera.
- Vertical supply runs that have never been cleaned. In East Baltimore blocks like Highlandtown and Greektown, supply ducts often rise 25-35 feet through interior wall chases with no access door. Forty years of debris, pet dander, and sometimes mold sits in a single dark vertical run. Camera inspection finds it; our tools remove it.
- Summer condensation and mold growth. Baltimore sits on the northern Chesapeake with summer relative humidity persistently above 65%. Cool supply ducts running through warm basement-to-upper-floor spaces condense moisture seasonally, creating conditions where mold grows inside the ductwork itself. This is a local pattern we address directly, not a generic talking point.
- Restricted parking and equipment access. Dense rowhouse streets in Hampden, Remington, and Waverly have narrow alleys and limited street parking. We plan van placement with homeowners before arrival so we don’t block trash pickup or fire lanes. That’s part of what “local” actually means here.

FAQs - Air Duct Cleaning in Baltimore
We access vertical runs from the air handler connection in the basement and from the register at the top floor, using agitation tools designed for narrow, long duct segments and negative-pressure extraction to pull loosened debris down. For runs that have never been cleaned, we thread the camera through first to identify blockages and kinked bends before any tool touches the duct. In a Highlandtown rowhouse, our technician threaded a camera up a 30-foot vertical supply run rising through an interior wall chase from a basement air handler, revealing 40 years of packed debris and mold. Using agitation tools with HEPA filtration and negative pressure, we removed the accumulation without disturbing the party-wall soffit, restoring airflow to the third-floor bedrooms. That run had no access door. We didn’t need one. Call (806) 606-6902 for a written price on your system.
Yes, but the scope is different. For condo units with shared duct stacks, we clean the portion of the ductwork within your unit and document exactly where the shared infrastructure begins. Written scope, written price, photo record of your accessible runs. If the building requires proof of insurance or a specific access notification, we provide that before the scheduled date.
The AC is part of the problem. Baltimore’s summer humidity stays above 65%, and when cool supply air passes through warm basement-to-upper-floor chases, condensation forms on the duct exterior and sometimes on the interior. That moisture, plus organic debris already inside the ducts, creates the conditions for mold. Running the AC longer increases the temperature differential. The fix starts with a camera inspection to locate the growth, then full cleaning with HEPA-filtered negative pressure. If the mold source is structural, the report tells you exactly where so you’re not paying for a repeat cleaning later.
Most single-system rowhouses take 3-5 hours, including camera inspection before and after. Homes with extreme buildup in vertical runs or multiple air handlers can take a full day. We’ll give you a time window when we write the price, and the photo record is delivered at the end of the job. Call (806) 606-6902 for an exact number on your system. Estimates are free.
Yes, when used correctly. The risk is not the brand, it’s the technique. Rigid rotary brushes can damage loose duct joints or the kinked 90-degree bends common in retrofit rowhouse systems. We use gentle agitation tools from Rotobrush and Nikro, sized for narrow, bent runs, paired with HEPA-filtered negative-pressure extraction so debris is captured rather than pushed into rooms. The camera before and after shows the work was done without causing new damage. Our equipment roster is published so you can verify what’s being used before you agree to a price.
How Baltimore’s Rowhouse Stock Changes What Duct Cleaning Requires
There is no other major American city with Baltimore’s concentration of rowhouses and no original ductwork anywhere in them. An estimated 70,000-100,000 units built between 1880 and 1945 were heated by cast-iron radiators. When forced-air HVAC arrived in the 1970s through 1990s, contractors crammed duct runs through basements, interior soffits, and wall cavities never built for them. The result is a city full of non-standard duct systems, sharp bends, vertical runs with no access doors, and decades of accumulated debris that standard cleaning equipment cannot address. In Highlandtown or Greektown, the air handler usually sits in an unfinished basement, and supply runs rise through interior wall chases to second and third floors. If you bought one of these homes between 2015 and 2025, the ductwork has likely been accumulating debris for longer than you’ve owned the house.
