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 HVAC Cleaning Across Severna Park
HVAC cleaning in Severna Park typically runs $285-$540 for a full-system clean that includes the evaporator coil, blower, and air handler, and most jobs wrap up in under four hours. If you’re chasing musty air from the registers, a persistent gray-orange dust on the supply vents, or allergy symptoms that start the moment the air kicks on, the answer is rarely the $79 duct-cleaning special. On the Severna Park peninsula, between the Severn and Magothy Rivers, we spend most of our time fixing what moisture and pollen have already done inside the system. Call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
We work throughout Severna Park weekly: along Ritchie Highway, through the neighborhoods off Benfield Road and Bayberry Drive, out toward Round Bay and Berrywood. Our crews know the difference between a 1968 colonial’s return-air chase and a 1995 Great Room open-loop system, because we’ve opened both often enough to know what’s inside. That local familiarity matters when the humidity won’t let up and the ductwork won’t dry out.
HVAC Cleaning in Severna Park is work that should leave you with documentation, not a vague promise that something got better. You’ll get a photo record of the inside of every duct run, before and after. That’s part of every job, not an upsell.
Why CleanRun Air Duct Cleaning Is Severna Park’s Preferred HVAC Cleaning Company
Since 2013, CleanRun has put a written price in front of every homeowner before starting, and a camera inside every duct before saying a word about what was found. The company was founded under the same operating rules we still run by today, what we call the H.A.V.E.N. Standard. Tomas Reyes built the business on a simple idea: show the customer the evidence, name the actual fix, put the number on paper, and stand behind the work for a full year. That’s the 365-Day Done Right Promise, and it is written on the job record, not rattled off over the phone.
Severna Park homeowners tend to research thoroughly before making a decision. They read reviews, compare pricing approaches, and ask for documentation. We answer that with a Free Second Opinion on any written estimate, a published license number on our paperwork, and technicians who identify themselves by name before entering the home. Background-checked and uniformed, every time.
We don’t operate a call center that serves everyone and knows no one. Crews for Severna Park are dispatched and scheduled from our Baltimore office, but the people handling your job know Anne Arundel County’s housing stock. That means they know to inspect crawl-space duct joints and grade-level intakes before recommending a scope of work, because Severna Park’s problems start there.
Our HVAC Cleaning Services in Severna Park
The HVAC Cleaning work that actually changes indoor air quality goes well beyond brushing some dust out of trunk lines. Here’s what we perform most often on homes across Severna Park.
Evaporator Coil Cleaning
Your evaporator coil sits above the furnace or inside the air handler and gets wet every time it runs. In Severna Park’s humidity, that coil stays damp longer and turns into a biological film, especially from June through September. We remove the panel, photograph the coil, and clean it with professional-grade coil products, not a spray bottle from a hardware shelf. A coil left fouled is a system that re-contaminates the ducts within weeks.
Blower Cleaning
The blower wheel pushes every cubic foot of air you breathe. When it’s matted with dust, mold fragments, and embedded pollen, it’s releasing that load into the supply runs all day. We pull the blower assembly, detail the wheel and housing, and document the condition in the photo record. Homes on wooded lots, especially those with grade-level intakes, tend to have the heaviest buildup on the forward curve of the blower fins.
Condenser Cleaning
The outdoor condenser coil sheds heat into the outside air. On Severna Park’s shaded lots, that coil collects fine organic debris, pollens, and the dust of decomposing hardwood leaves. A clogged condenser drives up your electricity cost and raises head pressure in the system. We clean the coil with the right pressure and chemistry and show you the before-and-after photos.
Air Handler Cleaning
The air handler is the box that holds the coil and the blower. In homes running the HVAC system heavily during Maryland’s humid shoulder seasons, the interior of that box becomes a damp enclosure that rewards mold. We clean the interior surfaces, apply appropriate coil treatments when indicated, and verify drainage so the unit doesn’t sit in its own condensation pan.

BeforeAfterTrusted Brands We Service in Severna Park
Seven out of ten homes we visit in Severna Park run equipment from the major manufacturers installed during the 1990s and 2000s, and we service them all. We use professional-grade cleaning and diagnostic equipment from Rotobrush, Nikro, Guardsman, and Honeywell, so the job is done with the same caliber of tools the manufacturer would recognize. Homeowners who want to verify equipment before agreeing to a price can look these brands up independently. We don’t believe the equipment should be a mystery.
Common HVAC Cleaning Problems We See in Severna Park Homes
- Mold re-establishing within weeks of a duct-only cleaning. Severna Park’s humidity keeps the interior of the air handler damp. If the evaporator coil and handler interior aren’t cleaned at the same time as the ducts, the system simply re-seeds the supply runs with new biological material. Coil cleaning is not an add-on here; it’s the only way the job holds.
- Yellow-green dust in the ducts confused with mold. Severna Park’s oak and tulip poplar canopy produces an enormous spring pollen load, much of it pulled through grade-level intakes near decks and shaded foundations. We camera-inspect and identify pollen deposits by color and texture, which prevents unnecessary chemical fogging and gets at the actual mechanical fix.
- Disconnected crawl-space duct joints drawing damp air into bedrooms. In 1960s and 1970s homes, especially ranches and split-levels over vented crawl spaces, duct runs may have separated at a seam. The system then pulls crawl-space air directly into the living space, carrying moisture, mold, and whatever else is down there. This is a structural issue that cleaning alone cannot fix.
- Condensation pooling in low ducts during shoulder seasons. When outdoor dew points are high and the system short-cycles, supply ducts in cool crawl spaces can sweat. That condensation absorbs dust and pollen from the airstream and becomes a paste. Long-term, it corrodes metal ducts and breeds microbial growth, and it’s a pattern we see far more often in Severna Park than five miles inland.
Pricing for HVAC Cleaning in Severna Park, MD
A whole-system HVAC cleaning in Severna Park, including the evaporator coil, blower, air handler interior, and full duct runs, typically runs $285-$540 for most single-zone homes. Larger homes with two air handlers and complex duct layouts can run $540-$850. The price is written before any work begins, under Haven Standard Clause 1, and it does not change unless we find something that requires additional scope, which we would document and price separately in writing before proceeding.
We don’t quote per-vent pricing, and we don’t use a teaser coupon as the entry point to a larger bill. The number you see is the number the job costs. If you have a competitor’s written quote, bring it in and we’ll put our own number next to it, line by line, at no charge. That’s the Free Second Opinion.

FAQs - HVAC Cleaning in Severna Park
Because the source of the moisture was never addressed. If the evaporator coil and air handler interior aren’t cleaned at the same time as the ducts, the damp, biofilm-covered coil re-contaminates the supply runs within weeks. In Severna Park’s humidity, the coil and handler are biological reservoirs. Clean them and the ducts, or clean nothing that will last. Call (806) 606-6902 and we’ll camera-inspect your system before recommending a scope.
More often than not in Severna Park, it’s pollen from oak and tulip poplar trees pulled into the system through grade-level intakes. We identify it by color, texture, and location using a camera inspection. Mold has a different presentation and tends to colonize the damp interior surfaces of the coil and handler, not sit as loose dust on the duct floor. If it’s pollen, mechanical source removal solves the problem. If it’s mold, the moisture driving the mold has to be fixed. Call for a documented answer, not a guess.
You can’t tell from the living space, which is exactly why we camera-inspect every accessible run. Signs include a musty smell that worsens in summer, visible separation at duct joints in the crawl space, and dust or debris patterns on the supply registers near the outside walls. We found a supply duct separated at a joint in a 1970s colonial off Benfield Road recently, pulling damp crawl-space air and green pollen dust into the master bedroom. The fix was source removal under negative pressure with HEPA filtration, joint sealing, and a full coil and blower clean. Call (806) 606-6902 and we’ll inspect before quoting a repair.
Because the coil is wet every time the AC runs, and in Severna Park’s humidity it stays wet longer than it would five miles inland. That turns it into a microbial growth medium that re-seeds the ductwork weeks after a duct-only cleaning. In a moisture-heavy coastal climate, coil cleaning is not an optional add-on; it’s the prerequisite for any cleaning that’s supposed to hold. We’ll show you the coil before and after.
No. Duct cleaning removes what’s already in the system, but Severna Park’s spring pollen load is constantly being drawn into the ducts through outdoor air intakes near grade. Without also cleaning the coil and blower, sealing crawl-space joints, and addressing intake placement, pollen will reappear in the supply runs within the same season. The answer is a documented whole-system clean, not a fogging treatment with a temporary effect. Call (806) 606-6902 for a written price.
