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 Severn
Air duct cleaning in Severn typically costs $425 – $695 for a standard single-system home, with the final figure set before any work begins, not after. That price covers source removal on the entire duct run, not a quick pass over the registers. If you’re off Telegraph Road or tucked into a 1970s rancher near Provinces Park, we know these homes and their duct geometry. You’ll get a written price, before-and-after photos of your own ducts, and a live arrival window you can track from your phone. Call (737) 727-2314 and a real person answers, any hour.
Why Cardinal Air Duct Cleaning Is Severn’s Preferred Air Duct Cleaning Company
Severn homeowners call us because our process matches what this area’s housing stock actually needs. The neighborhoods around Severn-Danza Park, Stillmeadows, and the Route 175 corridor are full of mid-century ranches and split-levels with original sheet-metal trunk lines that run twenty, thirty, sometimes forty feet between the air handler and the farthest bedroom register. A short-visit cleaning that only addresses the first few feet of duct does almost nothing for those homes. Our techs cut proper access ports and run negative-pressure extraction, meaning the loosened debris goes straight into a Nikro HEPA vacuum instead of back into your living room.
Omar Haddad, who leads our Severn-area crews, insists on camera inspection before quoting anything beyond a standard cleaning. You see what’s actually inside your ducts. Then you decide. Every job includes the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. That applies to every booking, no exceptions, no fine print.
Part of the Relay Home Co. family, founded 2005, Cardinal holds every Severn job to The Relay Visibility Guarantee. You get a live trackable arrival time, background-checked and uniformed technicians, before-and-after photo documentation, and a digital invoice you can pay from a link. Dispatched and scheduled from the brand’s Baltimore office, crews serve Severn locally and regularly.
Air Duct Inspection in Severn
Air Duct Inspection in Severn is a camera walkthrough of your supply ducts, return ducts, and air handler compartment, and it’s the only way to know whether you actually need cleaning. A standard inspection runs $95 – $175 and is credited toward the cleaning if you book one. In Severn’s older homes, inspection matters more than in newer construction because long trunk runs hide buildup far from the registers where you can’t see it. You get photos and video stills of what we find, not a verbal summary.
What the Inspection Looks For
We check for drywall dust, pet hair, insulation debris, and anything restricting airflow at the blower motor. We also identify whether buildup sits in the supply side, the return side, or both. That changes the scope of the job and keeps the price honest.
When Severn Homeowners Need One
After renovations, after moving into an older home, or when dust returns within days of cleaning. If a previous cleaning left no photos and no access ports cut, an inspection tells you what was missed.
Residential Air Duct Cleaning in Severn
Residential Air Duct Cleaning in Severn means full source removal across the entire system: supply ducts, return ducts, trunk lines, and the air handler. Our standard residential cleaning runs $425 – $695 for a single-system home based on square footage and the number of branch runs, and that’s one flat price per system agreed before we start. No per-vent pricing. No add-ons at the door. Older Severn ranches with long trunk lines and multiple returns near the BWI flight path tend to sit at the higher end because the runs are longer and the buildup is deeper.
Negative-Pressure Extraction
We cut access ports, seal the system, and run a Rotobrush agitation tool through every branch while a Nikro HEPA vacuum maintains negative pressure. Debris leaves the system. It doesn’t circulate back into the house. For homes with heavy particulate loads, we run Abatement Technologies containment units to keep the work area isolated.
What You See When We Finish
Before-and-after photos of the inside of your ducts, loaded on a tablet you can review while the tech is still there. If a section looks unchanged, we redo it before we leave. That’s not a promise; it’s the standard.
Trusted Brands We Service in Severn
Our Severn crews work with Rotobrush rotary brush systems, Nikro HEPA-rated vacuum extraction, and Abatement Technologies containment units. We also install and service Aprilaire and Guardsman filtration products for homeowners who want better air quality after the ducts are clean. Because we run this equipment daily, we keep the consumables and common replacement parts stocked on our trucks, which means fewer supply runs and faster turnaround for Severn jobs. If you’ve had a previous company tell you your ducts need specialized treatment we can’t perform, call us; we’ll tell you plainly what’s actually needed.
Common Air Duct Cleaning Problems We See in Severn Homes
- Drywall dust caked in long trunk runs. Severn’s older homes near Quarterfield Road and Reece Road often have original 1960s and 70s sheet-metal trunks with twenty or more feet of run between the air handler and the farthest register. Renovation dust settles deep in those runs and stays there until source removal pulls it out.
- Pet hair packed around the blower motor. Homes in Severn with two or more pets routinely show blower compartments restricted enough to reduce airflow. A filter catches what reaches it; the blower traps the rest.
- Per-vent cleaning jobs that missed the trunk entirely. We’ve followed behind companies that charged by the register and spent ninety seconds at each one. The visible grilles looked fine. The trunk lines were coated. Camera inspection shows the difference.
- Buildup near the returns from the BWI flight path. Homes along the approach corridors see more fine particulate drawn into returns. It settles in return ducts first, then recirculates when the system runs. Regular filter changes help, but they don’t remove what’s already lining the ducts.
Pricing for Air Duct Cleaning in Severn, MD
A standard residential cleaning in Severn runs $425 – $695 for one full system. Commercial duct cleaning in Severn runs from $0.18 – $0.32 per square foot depending on system size and access.

Supply-only or return-only cleanings fall on the lower end; full-system source removal with air handler cleaning sits at the higher end. What we won’t do is quote a per-vent price.

FAQs About Air Duct Cleaning in Severn
Every 3 to 5 years for most Severn homes, though homes along the BWI flight path or with multiple pets may need it every 2 to 3 years. If you’ve just finished a renovation in an older Severn rancher, schedule it sooner. If your ducts were cleaned properly less than two years ago and you’re not seeing dust return, you likely don’t need it yet. We’ll tell you that on the phone before booking anything. Call (737) 727-2314 and describe your home; we’ll give you an honest answer.
One flat price per system. Never per vent. Per-vent pricing creates an incentive to move quickly over each register and skip the long trunk runs that define Severn’s older ranches. Our price is written before we start and it does not change at the door. That’s the whole point of The Relay Standard.
NADCA is the National Air Duct Cleaners Association, and its standard means source removal, not just surface wiping. In a Severn home, that means cutting access ports, agitating debris from the full length of the trunk and branch runs, and extracting it under negative pressure with HEPA filtration. If a company says they clean “to NADCA standards” but doesn’t cut access ports or run negative pressure, they aren’t. Ask to see the before-and-after photos.
Yes. Camera inspection before the cleaning shows you the inside of your ducts in real time. After the cleaning, we photograph the same sections so you can compare. That’s built into every Severn job, not an add-on. If a previous company cleaned your ducts and left no photos, call us; we’ll inspect and tell you what’s actually there. (737) 727-2314.
We schedule by appointment with live arrival windows you can track, not vague four-hour blocks. While we don’t promise same-day service, we do answer the phone live around the clock, and Severn appointments are often available within a few days. Call (737) 727-2314 and a real person will check the schedule for you immediately.
