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.

Severna Park’s homes fight a specific battle: ductwork running through vented crawl spaces that stay damp year-round. That’s the whole story on this page. We’ll explain what we find inside those ducts, what it costs to put right, and why the fix often involves more than a cleaning.
Why CleanRun Air Duct Cleaning Is Severna Park’s Preferred Air Duct Cleaning Company
CleanRun was established in 2013 and has completed over 52,000 home visits, every one of them with a written price before work started and a documented photo record when the crew left. That record matters in Severna Park, where the question is never “are the ducts dirty?” but “can you show me what’s actually inside them?” We can. We photograph the inside of every duct run before and after, and those photos are part of your job record, not something we wave at you on a tablet before asking for a signature.
The Air Duct Cleaning in Severna Park homeowners call us for usually starts with a specific observation: a return duct pulling crawl-space air, a crushed flex run under a 1970s colonial, or a supply register blowing visible dust onto window sills. Our crews work under the H.A.V.E.N. Standard, with background-checked, uniformed technicians identified by name before arrival. Haven Standard Clause 1 is the one that matters most: a written price before any work begins. That’s not a marketing line. It’s the operating rule.
Tomas Reyes, who leads CleanRun, built the company around a simple position: if the work can’t be photographed and put in writing, it doesn’t count. That’s why the 365-Day Done Right Promise is a written guarantee on every job, not a policy subject to manager approval. If it’s not right, we make it right. That promise travels well to Severna Park, where homeowners tend to read the fine print.
Our Air Duct Cleaning Services in Severna Park

Residential Duct Cleaning
Most Severna Park homes we clean are 1960s-1980s ranches, colonials, and split-levels with original sheet-metal or early flex ductwork. A standard residential cleaning covers every supply and return run, the plenum, and the register boots. We use negative-pressure extraction with HEPA filtration, which means the debris is pulled out of the house, not stirred into the living space. In a Severna Park home with a vented crawl space, that distinction is the entire ballgame.

Commercial Duct Cleaning
Severna Park’s commercial spaces, from medical offices along Ritchie Highway to daycare centers and small office parks near Robinson Road, have HVAC systems that run longer hours and accumulate debris faster than residential systems. We clean commercial duct systems with the same documented photo record we provide on every residential job. A building manager in Severna Park should be able to see the before-and-after evidence in writing, especially if tenants have raised air-quality concerns.

Supply Duct Cleaning
Supply ducts are the runs that carry conditioned air from the air handler to your registers. In Severna Park’s humid microclimate, supply ducts develop a specific problem: condensation on the inside of the metal during summer, which traps pollen and dust, which then hardens into a film that resists simple brushing. We clean supply runs with powered agitation and negative-pressure extraction, then photograph each run after the work. If the camera shows damage, you see it. We don’t summarize it away.

Return Duct Cleaning
Return ducts are the neglected half of most systems, and in Severna Park they’re the half that matters most. Returns pull air from the house back to the air handler, and in older Severna Park colonials with vented crawl spaces, those returns often have separated joints or crushed flex sections that pull crawl-space air directly into the system. Cleaning the returns without fixing those separations is cosmetic. We clean returns thoroughly, but we also flag what the camera shows at every joint and connection.

Video Inspection
Before we recommend any cleaning scope, we run a camera through the ductwork. This is not an upsell. It’s how we know what we’re actually dealing with. In Severna Park, video inspection routinely reveals a few recurring findings: disconnected runs under crawl spaces, years of pollen deposit visible as yellow-green film, and return ducts that have been pulling crawl-space air for a decade. You see the footage. We point at what it shows. Then we write a scope and a price.

Full System Cleaning
A full system cleaning in Severna Park means every supply run, every return run, the plenum, the blower compartment, and the register boots. It’s the service we recommend when a home hasn’t had its ducts addressed since it was built, which describes a large share of Severna Park’s housing stock. Full system cleaning takes longer and costs more than a supply-side-only job, but it addresses the actual problem: a system that has been circulating crawl-space air and pollen through the entire house.
All of this is part of our Air Duct Cleaning service, delivered the same way on every job: written price first, documented photo record last.

Common Air Duct Cleaning Problems We See in Severna Park Homes

- Mold colonization in crawl-space duct runs. Severna Park sits on a peninsula between the Severn and Magothy Rivers, and the relative humidity under a vented crawl space here is measurably higher than inland Anne Arundel County. Ductwork in that environment stays damp, and mold takes hold inside supply and return runs alike. A cleaning alone doesn’t stop it. The crawl space moisture source has to be addressed.
- Separated return ducts pulling crawl-space air. On a job off Benfield Road, our techs found a return duct in a 1970s colonial that had separated at a joint in the vented crawl space, pulling damp crawl-space air and visible mold spores directly into the living area. We performed source removal under negative pressure with HEPA filtration, then sealed the run with mastic and replaced a crushed section of flex duct before reinstalling the register. That’s the kind of finding a camera inspection is for.
- Crushed or disconnected flex runs under the house. Flex duct from the 1980s doesn’t age well in a damp crawl space. It sags, tears, and separates. We see runs completely crushed under debris or disconnected at the trunk line, which means your system is heating and cooling crawl-space air instead of living-space air. No amount of register cleaning fixes this.
- Pollen deposits mistaken for mold. Severna Park’s oak and tulip poplar canopy produces some of the highest springtime pollen counts in the greater Annapolis-Baltimore corridor. Outdoor air intakes near grade or tucked under ground-level decks funnel that pollen directly into the duct system every April and May. The result is a yellow-green deposit on duct interiors that many homeowners assume is mold. Sometimes it’s pollen. Sometimes it’s both. A camera inspection tells you which.

FAQs - Air Duct Cleaning in Severna Park

Because the moisture source was never addressed. In Severna Park, ducts in vented crawl spaces stay damp year-round due to the peninsula’s tidal-river humidity. A cleaning removes the visible mold, but within months the crawl space re-supplies the moisture and the mold re-establishes. The fix is sealing the duct runs, repairing separated joints, and addressing the crawl space humidity. A cleaning alone is a partial job. We’ll show you the video, recommend the scope, and let you decide. Call (806) 606-6902 to schedule an inspection.
In Severna Park, it’s often both. The oak and tulip poplar canopy produces heavy springtime pollen loads that collect in ducts as a yellow-green film. The same ducts, if they run through a damp crawl space, also support mold growth. A camera inspection distinguishes the two, and that distinction matters because the fixes are different. Pollen calls for cleaning and air-intake repositioning. Mold calls for cleaning plus sealing and moisture control. We’ll show you the footage.
Fall is generally better. By late September, the spring pollen load has settled and the summer humidity spike has passed, so the ducts are in their most stable condition. Spring cleaning, right after pollen season, removes the visible deposit but hits right when humidity is climbing again. That said, if you have a known mold issue or a disconnected return run, schedule it whenever the problem is found. Timing matters less than fixing the underlying cause. Call (806) 606-6902 for a written estimate.
We clean both, and we prioritize the returns. In older Severna Park colonials with vented crawl spaces, return ducts are where the real contamination happens. Separated joints and crushed flex runs pull crawl-space air, mold spores, and humidity into the return side of the system. A supply-only cleaning is a partial job that leaves the majority of the contamination untouched. We clean every run and photograph every return duct before and after.
We check the crawl space. In a Severna Park ranch with no basement, the ductwork almost always runs through a vented crawl space, and that space is the source of most of the problems we find: disconnected runs, crushed flex, visible mold on the duct exterior, and signs of rodent activity. Video inspection through the crawl space happens before any cleaning scope is written. The crawl space tells the truth, and we document what it says.
