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.
Fast, Reliable HVAC Cleaning Across Severn
HVAC cleaning in Severn, MD typically runs $350 to $650 for a full system cleaning on a single-family home, with the work completed in 3 to 5 hours. That price covers source removal inside the air handler, evaporator coil, blower assembly, supply and return duct runs, and every register. We service Severn daily from our Baltimore scheduling office, with crews dispatched locally and live phone coverage at (806) 606-6902 whenever you call.
Severn isn’t a generic suburb. It wraps around Fort Meade, and that changes how HVAC cleaning gets done here. Turnover is constant. Homes cycle through military tenants on PCS orders, often with no maintenance continuity between occupants. The system you just bought with the house may not have been opened in two decades. We treat every Severn job as a clearance job: open it, document what’s inside, clean it to source, and hand you the photo record.
Why CleanRun Air Duct Cleaning Is Severn’s Preferred HVAC Cleaning Company
We founded CleanRun in 2013 with a simple rule that’s held for 52,000+ homes: write the price before any panel comes off. In Severn, that matters more than most places. Homeowners here are frequently buying on a timeline, sometimes sight unseen, from sellers who can’t speak to what’s inside the duct runs. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive with a written scope and the equipment to back it up.
Tomas Reyes runs the operation, and he’s built the Severn service pattern around one recurring observation: systems in this market get cleaned during transactions, not between them. That’s why we photograph the inside of every duct run before and after, and why we deliver that record as a standard deliverable, not an add-on.
Severn customers read the documentation we hand them. They want to see the 3-inch debris build-up at the first elbow, not hear a vague summary. They want the written price before work starts, under Haven Standard Clause 1. And they want the 365-Day Done Right Promise in writing, not in a sales pitch.
Our HVAC Cleaning Services in Severn

Evaporator Coil Cleaning
In Severn’s split-levels and colonials built from the late 1960s through the 1990s, we regularly find evaporator coils that have never been opened since installation. Summer humidity here sits above 80% for weeks at a time, and the coil runs wet all season. That wet surface catches everything the filter misses, and the result is a matted layer of biofilm and dust that drives cooling costs up and airflow down. A typical evaporator coil cleaning in Severn runs $150 to $300 as part of a full system service.
Blower Cleaning
The blower wheel in a Severn home with 30-year-old ductwork works like a dust sponge. We’ve pulled blowers from systems off MD-174 where the wheel fins were so caked with compacted lint and dander that the motor was laboring against its own resistance. Blower cleaning here runs $120 to $250, and it’s part of the full HVAC cleaning we do when the air handler is opened.
Condenser Cleaning
The outdoor condenser unit takes the worst of Severn’s pollen, lawn clippings, and construction dust from the constant development around Anne Arundel County. A clogged condenser coil can add 10 to 15 percent to monthly cooling costs. Condenser cleaning in Severn runs $100 to $200, depending on the unit size and condition.
Air Handler Cleaning
This is the service we emphasize most in Severn. The air handler is the crate that holds the evaporator coil, the blower, and the return air connections. In a home that’s cycled through several military tenants, the air handler is often the dirtiest component in the entire system, and it’s the one most often skipped by duct-only cleaning companies. Air handler cleaning in Severn runs $200 to $400 when done properly, which means removal of the housing panels, HEPA vacuuming of the cabinet interior, coil cleaning, blower extraction and cleaning, and reassembly with new filter media checked. You get the photo record on this service, because it’s the one where real work is visibly different from a rushed pass.

Common HVAC Cleaning Problems We See in Severn Homes

- Degraded flex duct insulation in original systems. Many Severn homes built in the 1980s and 1990s used flex duct with foil outer covering and fiberglass liner. After 30 to 40 years, that liner breaks down and sheds particles into the supply air. We find this often enough in homes near Severn Run and Pioneer City that it’s on our standard inspection checklist.
- No maintenance history across multiple occupants. Fort Meade drives constant turnover. A system that’s had five residents in a decade often has never been touched, because each one treated the property as a temporary assignment. Our crews photograph the coil before cleaning so incoming owners can see what the previous occupants lived with.
- Crawl-space condensation and mold. A significant portion of Severn’s older stock is ducted through crawl spaces. Ground moisture combines with humid mid-Atlantic air, and the result is persistent condensation inside supply runs. That’s a moisture source for mold in the ductwork itself, a separate problem from dust and debris.
- Clogged returns that starve the system. In busy homes near Jacobs Road and Quarterfield Road, returns get blocked by furniture, storage, and forgotten filter changes. We inspect return runs on every job and flag airflow restrictions in the written report, not just the cleaning itself.
Pricing for HVAC Cleaning in Severn, MD
These are written prices delivered before work starts. We price per system, not per vent, which means the quote you sign is the number you pay. Any competitor still advertising a flat $79 or per-vent rate gets the same scrutiny from us as they should from you: the offer is the bait, and the walk-up happens after the van arrives. Call (806) 606-6902 with system details and we’ll give you a fixed written price before scheduling.

FAQs - HVAC Cleaning in Severn

Homes near Fort Meade have unusually high tenant turnover on PCS cycles, and each transition creates a gap in maintenance. The previous occupant never had a reason to clean the ducts because they weren’t staying, and the next one inherits a system with no documented history. In our experience, these systems often carry 10 to 20 years of accumulated pet dander, dust, and humidity-driven mold. A pre-occupancy HVAC cleaning with a documented photo record gets the new owner to a known baseline. Call (806) 606-6902 and we’ll quote a fixed written price for your specific system.
We clean shared dryer vent stacks carefully and only after a camera inspection of the full run. In most Severn townhome communities, we coordinate with the HOA or property manager when the stack is connected to multiple units, and we use the written photo record to confirm before and after conditions at the transitions. We never run rotary brushes through a shared stack without first verifying the path and the connection points. If another unit’s run is compromised, we stop and document it before proceeding. Get a written price for shared-stack cleaning by calling (806) 606-6902.
The NADCA standard for air handler cleaning requires source removal, meaning the debris is removed from the system using negative pressure and HEPA filtration, not just stirred up and left in the ducts. In Severn’s colonial and split-level homes with original sheet metal ductwork, that means opening the air handler cabinet, cleaning the evaporator coil and blower, and then working through the supply and return runs with agitation equipment matched to the duct material. Every CleanRun job in Severn follows this standard, and the after-job photo record verifies it. Call (806) 606-6902 to ask about NADCA compliance and a written price.
Severn’s summer humidity keeps the evaporator coil wet and running for months at a time, creating the exact conditions that support mold and biofilm growth. Even if the duct runs look relatively clean in the photo inspection, the coil itself can be coated in a layer of microbial material that reduces cooling efficiency and degrades indoor air quality. Our technicians clean the coil as a standard part of every Severn HVAC cleaning, not as an upsell. Call (806) 606-6902 for a written price that includes coil cleaning in the base number.
Yes. We’ve cleaned many townhome systems in Severn where parking is restricted and the HOA limits window access. We do it with negative-pressure equipment that runs from the main door or through a ground-level access point, and we schedule the work during the HOA’s allowed hours. The process is the same source removal and HEPA filtration we use on single-family homes, just adapted to the space. Call (806) 606-6902 and tell us about your HOA’s restrictions; we’ll plan the job around them and give you a written price before anyone arrives.
If you’re buying, selling, or simply taking over a house in Severn, start with a documented system cleaning. Call CleanRun at (806) 606-6902 and ask for a written price. We’ll send a background-checked crew, open the system, photograph what’s inside, and clean it to source.
