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.
Air Duct Cleaning in Catonsville, MD: What It Costs and What We Actually Find
Air duct cleaning in Catonsville typically runs $390-$690 for a full system on a 1,500-2,200 sq ft home, with older homes retaining original 1950s-60s sheet-metal ductwork often landing at the higher end due to access difficulty and decades of accumulated debris. We give every Catonsville homeowner a written price before any panel comes off, and every job ends with a documented photo record of the inside of each duct run. That’s not a marketing line. It’s how we’ve operated since Tomas Reyes started CleanRun in 2013.
What we find in Catonsville homes is different from what we find in newer suburbs. The tree canopy here, the brick Cape Cods and ranchers off Frederick Road and Edmondson Avenue, the retrofitted central AC tied into ductwork designed only for heat, it all changes what lives inside your ducts and what it takes to get it out. Call (806) 606-6902 and we’ll walk you through what a cleaning on your home would involve.
Why CleanRun Air Duct Cleaning Is Catonsville’s Preferred Air Duct Cleaning Company
We’ve cleaned ducts in hundreds of Catonsville homes, from the brick Cape Cods off Frederick Road to the ranchers in Westchester and the colonials along North Rolling Road. Homeowners here tend to research before they call. They’ve read the horror stories about $79 whole-house coupons that turn into $900 invoices once the tech is in the driveway. So we lead with what those homeowners ask for: a written price before anything starts, and photos of what the ducts looked like before and after.
Every CleanRun tech is background-checked, uniformed, and identified by name before arrival. That’s Haven Standard Clause 3: Verified Crews. We run Rotobrush and Nikro negative-pressure extraction equipment, with HEPA filtration during source removal. When we leave a Catonsville home, the homeowner gets a photo record of the inside of every duct run, plus a written scope of work and a written 365-Day Done Right Promise. If the work isn’t right, we make it right. That’s a written guarantee on every job, not a policy that needs manager approval.
Our crews work Catonsville weekly. Scheduling is coordinated from our Baltimore metro office, and we know the streets, the housing stock, and the specific ways these homes collect debris. You’ll talk to a live person when you call, and you’ll get a straight answer about what your system needs. Most Catonsville full-system cleanings take 3-5 hours depending on home size and access to the plenum.
Our Air Duct Cleaning Services in Catonsville

Here’s what full-service Air Duct Cleaning looks like for Catonsville homeowners. The service area on this page covers Catonsville specifically, including the older blocks off Frederick Road, Edmondson Avenue, and the neighborhoods west toward Oella.
Residential Duct Cleaning
This is the core of what we do. For Catonsville homes built in the 1950s and 1960s, residential duct cleaning means camera inspection first, then source removal under negative pressure with HEPA filtration. We don’t brush-and-vacuum. We map the runs, identify dead zones, and photograph every run before and after. Homes that have never had the ducts cleaned in 50-70 years often need more access points created than a newer home would. That’s part of the written quote, not a surprise add-on.

Commercial Duct Cleaning
Catonsville has a mix of commercial spaces along Frederick Road, Baltimore National Pike, and the office parks near the Community College. Commercial duct cleaning requires different access equipment and often night or weekend scheduling to avoid disruption. We quote commercial jobs in writing the same way we do residential, with the full photo record delivered when the job’s done. If you manage a building in Catonsville with a neglected return side, we’ll show you exactly what the camera finds.

Supply Duct Cleaning
Supply ducts carry conditioned air into living spaces. In older Catonsville homes, supply runs are often original rigid sheet metal, which holds up structurally but accumulates decades of compacted dust. When a home had central AC retrofitted in the 1980s or 1990s, those supply runs sometimes got flex-duct branches tied in awkwardly. We inspect the entire supply side, identify collapsed or disconnected runs, and clean what’s actually there, not just what’s accessible from the register.

Return Duct Cleaning
The return side matters in Catonsville more than in almost any Baltimore County suburb. With the dense oak, maple, and elm canopy, return intakes pull in heavy pollen and organic debris every spring. Return ducts here clog faster, and once a return run is restricted, the entire system fights itself. We clean returns thoroughly, including the panned joist returns common in older brick construction, and we photograph the intake plenum before and after. Our Air Duct Cleaning in Catonsville work always includes the return side as standard. We don’t sell it as an add-on.

AfterWhat We Find in Catonsville’s Older Duct Systems
There’s a particular set of problems that keeps showing up in Catonsville homes built between the late 1940s and early 1970s. Here’s what we see most often:
- Disconnected flex-duct retrofits. Central air was added to many of these homes decades after they were built. The flex duct was run through crawlspaces and tight chases, and over time it sags, collapses, or pops off the collar entirely. Air gets pushed into the crawlspace instead of the bedroom. Cleaning alone doesn’t fix a disconnected run. It needs reconnection and sealing, which we quote in writing before we touch anything.
- Debris-packed dead zones. When 1950s gravity-warm-air plenums were repurposed for modern forced-air AC, the airflow was never quite right. Low-velocity sections of the system collect compacted dust that a standard cleaning pass won’t touch. We use camera inspection to find these dead zones, then access them directly. If we can’t get equipment to the debris, we tell you that and we show you the camera image.
- Condensation-driven mold in uninsulated metal ducts. Catonsville sits on the Piedmont Plateau west of Baltimore, and summer relative humidity routinely runs above 70%. Uninsulated metal ducts sweat. That moisture feeds mold and mildew growth in ducts that were never designed for air conditioning. Brushing alone will let it return within months. The fix is treatment, then sealing, then addressing the condensation at its source. We’ll show you the before photo, show you the after photo, and tell you honestly what will or won’t come back.
- Return-intake pollen overload. Every spring, oak and maple pollen moves through Catonsville in heavy waves. Return intakes pull that material directly into the system. In homes with original registers and gravity-warm-air ductwork along Edmondson Avenue, that pollen packs into returns and pushes past the blower into living spaces. It’s not just an allergy issue. It’s a blower motor working against a restricted intake, which shortens the life of the equipment.
What Sealing Costs in Catonsville, and Why It’s Often the Real Fix

Here’s something most duct cleaning companies in Catonsville won’t say plainly: cleaning is half the job. If your 1962 rancher has disconnected runs in the crawlspace or leaky joints at every plenum connection, you’ll clean the ducts and the system will pull dust right back in. Sealing is the repair that makes the cleaning last.
Duct sealing in Catonsville runs $180-$425 for targeted sealing of accessible leaks and disconnected runs, depending on how much access we need to create and how many runs are involved. Full-system sealing with mastic and mechanical fasteners on a 2,000 sq ft home runs $450-$900. We quote sealing as a line item in the written estimate, alongside the cleaning price. You’ll see both numbers before you agree to anything. And yes, we photograph the sealed joints too. If it costs money, it gets documented.
Trusted Brands We Run in Catonsville
We run Rotobrush and Nikro negative-pressure extraction equipment on our residential jobs, with HEPA filtration during source removal on every full-system cleaning. For air quality work and sanitizing, we use products carried through Honeywell and Guardsman distribution, applied only after the source removal is done. None of this is proprietary. You can look up every piece of equipment we name and see exactly what it does. We’d rather you do that before we arrive than wonder after we leave.

FAQs - Air Duct Cleaning in Catonsville
Because your home has three compounding factors: original sheet-metal ducts that have never been professionally cleaned, a dense mature tree canopy pushing heavy pollen into the return intakes every spring, and central AC retrofitted into a system designed only for heat. The combination creates biologically active debris accumulation that newer construction with properly designed ductwork simply doesn’t experience at the same rate. We recommend every 3-5 years for most Catonsville homes built before 1975, versus 5-7 years for newer builds in less canopied areas. Call (806) 606-6902 and we’ll give you a written assessment of your specific system.
Yes. We’ve done many of these homes, and the camera inspection tells us exactly what we’re working with before we start. The key is identifying the low-velocity dead zones where the retrofitted flex duct creates stagnant air and compacted debris collects. We access those zones directly rather than cleaning around them. If the flex duct has collapsed or disconnected, we quote the repair in writing alongside the cleaning. In a 1950s brick Cape Cod off Frederick Road, we once found the original sheet-metal runs had never been professionally cleaned, with disconnected runs in the crawlspace and a crushed flex-duct branch from a 1980s AC retrofit. We mapped the dead zones by camera, performed source removal under negative pressure with HEPA filtration, then sealed the leaks and restored airflow. That’s the complete job, not just the cleaning pass.
We stop and document it with the camera. Then we adjust the written quote to include the repair. We never proceed with cleaning alone on a system that has disconnected runs, because cleaning won’t hold and you’d be paying for work that gets undone. Reconnecting a run runs $60-$120 per connection, and replacing a crushed flex-duct section runs $85-$180 depending on length. You’ll see those numbers before we pick up a tool. Call (806) 606-6902 to schedule an inspection if you suspect your crawlspace runs have failed.
Catonsville’s summer relative humidity above 70% causes uninsulated metal ducts to condense. That moisture feeds mold and mildew growth on the dust and debris already inside the ductwork. Homes where AC was added to a heat-only system are especially vulnerable, because condensation management was never part of the original design. Treatment and sealing address the current growth, but the long-term fix often requires insulating the duct runs or addressing crawlspace humidity. We’ll show you the camera evidence and write up the options with prices. We won’t promise that a brush-and-spray job will hold when the physics says it won’t.
Yes. These are among the more technically interesting systems we clean in Catonsville. The original registers and gravity-warm-air plenums were built well, but they were never designed for forced-air AC. We use the video inspection to map what’s accessible, then perform source removal with the same negative-pressure equipment we use on newer systems. Access can be more involved, which is reflected in the written quote before we begin. If you’re in one of those older brick homes and you’ve never had the ducts cleaned, plan on a longer appointment. Call (806) 606-6902 for a free estimate, and we’ll tell you exactly what your system needs.
