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 Ellicott City
Air duct cleaning in Ellicott City typically costs $390-$680 for a full system, depending on home size and duct condition. CleanRun Air Duct Cleaning serves every Ellicott City neighborhood, from the 19th-century buildings along Main Street to 1980s colonials off Centennial Lane. We arrive with professional-grade equipment that uses negative-pressure extraction and HEPA filtration, not a shop vac bolted to a van. If you want to see what’s actually inside your ductwork before anyone touches it, call (806) 606-6902. Every job starts with a written price, and every job ends with a photo record of every duct run.
What makes Ellicott City different from Columbia or Catonsville is the valley itself. The Patapsco watershed traps humidity in ways that higher, flatter suburbs don’t experience. That moisture drives mold and dust-mite growth inside duct systems, which means what works for a neighbors home off Route 100 may miss half the problem in a split-level near Turf Valley. Our Air Duct Cleaning team has seen enough of these systems to know where to look first.
We serve the whole Ellicott City area with scheduled service that fits your calendar, not a rushed appointment window. When you call, a live person answers. When the crew arrives, they’re background-checked, uniformed, and identified by name before they walk in the door. That’s the H.A.V.E.N. Standard, and it has been our operating baseline since Tomas Reyes founded CleanRun in 2013.
Why CleanRun Air Duct Cleaning Is Ellicott City’s Preferred Air Duct Cleaning Company
We built our name in Ellicott City on a simple position: show the customer what’s there, then do what’s needed. Not before. A camera goes into the ductwork first. You see the inside of your supply and return runs before we recommend anything. Then you get a written price that doesn’t move. That’s Haven Standard Clause 1, and it’s why our 52,000+ completed jobs across the region include Ellicott City homeowners who had never seen the inside of their ductwork before we arrived.
Our customers in Ellicott City talk about the documentation. After every job, CleanRun provides a Documented Photo Record of every duct run: before and after, same angle, same lighting. That record is yours to keep. If a neighbor ever asks what duct cleaning actually does, you can show them. No other company in Howard County makes that a standard deliverable. We have done this since our first job in 2013, and we have never once skipped it.
Response to Ellicott City is scheduled around your availability. We dispatch crews from our Washington, DC office, and we cover Ellicott City thoroughly: Route 40, Centennial, Turf Valley, the historic district, and every subdivision in between. If you have a 365-Day Done Right Promise question six months after the job, you call the same number and talk to the same team. That guarantee is written on every invoice, not left to a manager’s mood.
Our Air Duct Cleaning Services in Ellicott City
Residential Duct Cleaning
Most Ellicott City homes run 10-18 duct runs, depending on the floor plan. A 1980s colonial off Centennial typically has two supply trunks, one return, and several flex branches tucked into joist bays. We clean every run with negative pressure, meaning the system pulls debris out while it stays contained, and we photograph each run before and after. In homes near the Patapsco, we often find the return side carrying dust that’s been drawn in from a damp crawlspace for years.
Commercial Duct Cleaning
Ellicott City’s lower historic district mixes 19th-century stone buildings with modern retail and restaurant spaces. Those duct runs are often irregular, retrofitted multiple times, and hiding silt from the 2016 and 2018 floods. Our commercial work starts with a video inspection of the entire system, then a written scope and price. We document everything. If a building owner in Old Ellicott City asks for proof, the photo record is part of the standard job file.
Supply Duct Cleaning
Supply ducts move conditioned air into your rooms. In Ellicott City’s 1970s-1990s housing stock, those supply runs are often original flex material that has sagged, pulled loose from a boot, or been crushed by a renovation. Cleaning alone won’t fix a crushed run. We identify that during inspection, show it to you on camera, and quote the repair or sealing work alongside the cleaning. You decide what gets done, in writing, before anything starts.
Return Duct Cleaning
Return ducts pull air back to the blower. In homes near the river valley, the return often draws from a musty basement or crawlspace, pulling mold spores and dust into the entire system. We clean the return side as carefully as the supply side, and we check the filter housing and air handler cabinet for moisture damage. If the return is the source of the musty smell, we tell you. And we document it.
Full System Cleaning
A full system clean includes supply and return runs, the plenum, the air handler, and the registers. In Ellicott City, where valley humidity is a constant pressure, we recommend this scope for any home with original ductwork that has never been cleaned. The cost runs $450-$680 for most three-to-four-bedroom homes, and includes the photo record, the written price, and the 365-Day Done Right Promise.
Video Inspection
Before we clean, we look. A small camera goes into the ductwork and shows you the inside of every run: dust depth, debris, mold stains, disconnected segments, crushed flex, anything. This is not an add-on. For homes in or near the historic district, the video inspection is how we find the silt lines and mold blooms left behind by the floods. You see it before we recommend a fix. That’s the whole point.

BeforeAfterTrusted Brands We Service in Ellicott City
We work on the equipment our customers already have, and we use professional-grade tools from manufacturers you can look up. On Ellicott City jobs, you’ll see Rotobrush and Nikro extraction systems, plus Honeywell and Guardsman components when replacements or air quality upgrades are part of the written scope. We don’t install mystery brands. If a furnace component fails during a cleaning job, we note it on the job record and give you a written quote for the replacement. No pressure, no surprise invoice. That’s the same standard for a 19th-century building on Main Street or a 1990s colonial in Turf Valley.
Common Air Duct Cleaning Problems We See in Ellicott City Homes
- Post-flood mold from 2016 or 2018. In the lower historic district and surrounding streets, duct interiors can still carry visible silt lines from the Tiber Branch floods. Homeowners assume their visible repairs covered the HVAC. They often didn’t. We see mold blooms inside return runs that have been recirculating spores for years.
- Crushed or disconnected flex duct from the 1970s-1990s. Original flex runs in colonials and split-levels often sag in joist bays, pull off the boot at the register, or get crushed during basement finishing. Cleaning a crushed run does nothing. Sealing and re-supporting is the real repair, and we quote it separately.
- Persistent musty smell from valley humidity. The Patapsco watershed keeps basements and crawlspaces damp longer than in Columbia or Catonsville. That humidity migrates into duct insulation and the air handler cabinet. A basic cleaning removes the visible dust but not the moisture-driven odor. We address the source, not just the symptom.
- Return-side contamination from damp crawlspaces. When the return draws air from a musty crawlspace, it vacuums spores and dust into the entire duct system. In Ellicott City’s older homes, this is one of the most common root causes of recurring dust and allergy complaints. We identify it on video and tell you what it costs to fix.
Pricing for Air Duct Cleaning in Ellicott City, MD
A full system clean for a typical Ellicott City single-family home runs $390-$680. Smaller homes or single-floor ranches start around $320. Larger homes with multiple zones or a finished basement with extensive ductwork can run $700-$900. Commercial jobs in the historic district are priced per duct run after a video inspection, with whole-system pricing agreed in writing before work begins.
What affects the price: the number of duct runs, the condition of the flex or metal duct, whether there’s flood sediment or mold requiring source removal, and whether sealing or repair work is needed. We don’t quote a teaser price and inflate it later. The written price you approve is the price you pay. Bring a competitor’s quote and we’ll put our number next to it in writing. That’s our Free Second Opinion, and it costs nothing.

FAQs - Air Duct Cleaning in Ellicott City
Look for silt lines or dark mold staining inside the ductwork, especially in lower-level returns or runs that run through old foundations. Homes in the lower historic district and along the Tiber Branch watershed are at highest risk. We document what’s there with a video inspection and a photo record, so you know exactly what you’re dealing with. Call (806) 606-6902 to schedule a documented inspection.
Cleaning removes debris, but it does not repair a crushed flex run or a duct that has pulled off the register boot. Homes from that era often have original flex material that has sagged through joist bays or been pinched during a renovation. Our video inspection pinpoints exactly where the airflow loss is happening, and we quote the sealing or re-support work separately. Call (806) 606-6902 with your symptoms and we’ll tell you what we’d check first.
Yes. The historic district’s 19th-century buildings have irregular duct routing, retrofitted HVAC systems, and a real history of floodwater entering the ductwork in 2016 and 2018. Columbia’s newer, purpose-built ducts don’t carry that same post-flood contamination risk. In Old Ellicott City, a video inspection and mold assessment are standard parts of the job. We bring the same equipment and the same written pricing, but the scope is informed by the flood history and the building stock.
Negative pressure means the extraction system pulls air and debris out of the ductwork continuously during cleaning, so what we dislodge doesn’t blow into your living spaces. HEPA filtration captures the fine particles and mold spores instead of exhausting them outside. For Ellicott City homes with post-flood sediment, this containment is the difference between removing contamination and spreading it. Call (806) 606-6902 if you want to know whether your system needs this level of cleaning.
Every 3 to 5 years for most Ellicott City homes, and every 2 to 3 years for homes in the valley or near the Patapsco watershed where humidity and return-side contamination are heavier. Homes with allergies, pets, or recent renovation work may need more frequent service. We’ll give you an honest recommendation after the video inspection, not a blanket schedule that guarantees another visit. Call (806) 606-6902 for the written scope and price.
Ellicott City’s Flood History and What It Means for Your Ductwork
Ellicott City’s lower historic district flooded catastrophically in July 2016 and again in May 2018, when the Tiber Branch watershed overwhelmed Main Street. The floodwater didn’t just soak floors and foundations; it pushed sediment, silt, and contaminated water into the HVAC systems of the commercial and residential buildings it reached. Property owners did what was necessary to reopen. Walls were rebuilt, floors were replaced, storefronts were restored. But the ductwork often stayed as it was: stained with silt, coated in dry mold spores, and sitting damp in the stone basements of buildings that were never designed to dry quickly.
Our technicians still find visible silt lines and mold blooms inside duct runs in the lower historic district. Some of those lines trace back to the 2018 flood. Some trace back to 2016. The homeowners or building owners had no idea the damage extended into the HVAC system, because no one had ever looked inside with a camera. That’s why our video inspection is not an optional extra on Ellicott City jobs. It is the whole starting point.
Cleaning alone is rarely the final fix. If the duct insulation is saturated, if the return run is pulling from a damp crawlspace, if the flex has sagged and allowed sediment to settle, then a simple cleaning will remove the visible debris and leave the underlying problem. The restoration work is what actually stops the spores from recirculating. We tell you what’s needed, show you why, and put the price in writing. You make the call. That’s how we’ve worked since 2013.
What We Found in a Route 40 Colonial
In an older colonial off Route 40, our tech found the original flex supply runs crimped behind a finished basement soffit and a crushed return under the slab. The homeowner had lived with a musty smell and weak airflow for years, assuming the house was just old. We used negative pressure with HEPA filtration to source-remove the debris, then sealed and re-supported the runs. Static pressure came back. The smell was gone. The fix wasn’t miraculous. It was specific, documented, and done at the price we quoted before the panel came off. That’s the CleanRun standard.
The Humidity Problem: Why Ellicott City Ducts Get Dirtier Faster
Ellicott City sits in a river-valley topography carved by the Patapsco watershed. The valley holds summer humidity and slows drying after rain events, much more than the flatter, more open suburban terrain of neighboring Columbia or Catonsville. That humidity does not stay outside. It migrates into basements and crawlspaces, into the insulation around ducts, and into the air handler cabinet. Dust that would stay dry and inactive in a higher, drier home becomes damp and sticky here. Mold and dust mites multiply. The musty smell that keeps returning after a basic cleaning is a sign that the moisture source was never addressed.
For Ellicott City homeowners, this means regular duct cleaning is more consequential than in surrounding communities. It’s not cosmetic. It’s a direct response to the way this valley behaves. We plan our cleaning scope around that: checking the return side for dampness, inspecting the air handler cabinet, and recommending sealing or insulation work where the moisture is coming through. If you live near the Patapsco or in a low-lying part of the valley, we’ll likely recommend a different cleaning frequency than a friend in Columbia needs.
Why the Photo Record Matters in Ellicott City
Duct cleaning is a service you can’t watch. The technician disappears into the basement or the attic, and you’re left trusting that something was actually done. That’s the structural problem with this industry, and it’s the problem CleanRun was built to answer. We don’t ask for trust. We hand you a Documented Photo Record of every duct run, inside, before and after. You see the silt line in a return run off Main Street before we clean it. You see the same run after. If the work wasn’t done right, the photos will show that too. And the 365-Day Done Right Promise means we come back and make it right.
Tomas Reyes set this standard in 2013, and 52,000+ homes later, it hasn’t changed. In Ellicott City, where flood history and valley humidity make ductwork a serious contamination concern, a photo record isn’t a luxury. It’s the difference between knowing and hoping.
