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 Ellicott City
Air duct cleaning in Ellicott City, MD typically costs between $395 and $795 for a whole-home cleaning, depending on the number of vents and whether your system needs plenum work or just run cleaning. Most homeowners here see the job completed in 4 to 7 hours, with a written price handed over before a single duct is touched. If you’re noticing dust building up on registers, a musty smell when the blower kicks on, or family members sneezing more inside than out, call (737) 727-2314 and we’ll walk you through what your home actually needs. We know Ellicott City from Dorsey Hall to downtown Main Street, and we’ve worked on enough systems here to know what each housing era throws at a duct cleaner.

No four-hour appointment windows. No mystery about who is showing up.

Written guarantee on every repair. Free second visit if a repair fails.
We’re part of the Relay Home Co. family, founded 2005, and our Ellicott City crews carry professional-grade equipment: Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. That’s a different category of machine than a truck-mounted shop vac. We also answer the phone with a live person, 24/7. No voicemail loops.
Air Duct Repair in Ellicott City
Air Duct Repair in Ellicott City usually means one of three things: a separated joint in a basement trunk line, a crushed flex run in a finished crawlspace, or a return drop that’s pulling air from a damp or dusty cavity. In older Ellicott City homes near the Patapsco, we often find duct sections that have sagged open over decades of humidity swings, letting conditioned air escape into a crawlspace instead of a bedroom. The fix typically runs $180 to $450 depending on access and materials.
Cracked and Disconnected Trunk Lines
Rigid metal trunk-and-branch systems, common in Ellicott City homes built from the 1970s onward, are durable but not immune to time. A separated joint at a plenum or a cracked takeoff collar can quietly dump heated or cooled air into a basement. We reseal with mastic and foil-backed tape, never duct tape. If the section is crushed or rusted through, we replace just that run and photograph the finished work.
Return-Side Leaks and Debris
The return side of a system is under negative pressure, which means it pulls air from wherever it’s connected. If a return drop has come loose in an unfinished basement, it’s pulling dust, insulation fibers, and whatever else settles down there straight into the blower. We inspect the entire return path during a repair, not just the visible vent, then seal and document everything before we leave.
Ductwork Cleaning in Ellicott City
Ductwork Cleaning in Ellicott City has to account for two very different housing stocks. Because Ellicott City mixes 18th- and 19th-century mill-town homes near the Patapsco with 1970s – 1990s colonials west of Route 29, duct cleaning here means two very different jobs: flexible duct runs with 4-inch branches in older homes versus rigid metal trunk-and-branch systems with lots of accessible crawl or basement duct in the newer subdivisions. We don’t treat them the same. Whole-home ductwork cleaning in Ellicott City typically costs $395 to $795, and we quote one flat rate per system, never per vent.
Full System Cleaning
A full system cleaning includes the supply runs, the return runs, the trunk lines, the plenums, and the air handler itself. We set up HEPA filtration and negative pressure at the air handler, then agitate the duct interiors with rotating brushes before extracting everything into the vacuum. Negative-pressure extraction means the loosened debris goes straight into the machine, not back into your living room. This is the service most Ellicott City homeowners need when they’ve never had the system cleaned or it’s been more than five years.
Video Inspection Before and After
When we clean ducts in Ellicott City, we run a camera inspection before and after. This isn’t a gimmick. We push a small camera through the trunk and branch lines to document what’s actually in there, then capture the same runs after cleaning. You get before-and-after photographs of your own duct interiors, not stock images of someone else’s house. That’s the Relay Standard: proof of the work, every time.
Trusted Brands We Service in Ellicott City
Most Ellicott City systems use a mix of manufacturer equipment and field-assembled ductwork. We clean and service equipment from all major brands, and we stock common replacement filters and components from Honeywell, Aprilaire, and Guardsman, so we can install a fresh filter at the end of a cleaning without a follow-up trip. When repairs require parts, our familiarity with Rotobrush and Nikro extraction systems means we carry the right tooling for just about any duct configuration we encounter in Ellicott City homes. Fast turnaround here means not having to wait a week for a part that should already be on the truck.
Why Per-Vent Pricing Falls Apart in Ellicott City
Some duct cleaners in this market quote a low teaser number per vent, then count 20, 25, or even 30 registers in a finished Ellicott City basement and present a much larger invoice at the door. That’s the bait-and-switch that gives this trade its reputation. We don’t do per-vent pricing. We count your registers, quote one flat price for the entire system in writing before any work starts, and that number doesn’t change when the technician arrives. Our final invoice matches the written estimate. Always.
Common Air Duct Cleaning Problems We See in Ellicott City Homes
- Humidity-driven duct sweating in mill-town basements. Older Ellicott City homes near the Patapsco sit in a humid river valley. When cool air runs through uninsulated metal ducts in a damp basement, condensation forms and dust clings to the wet interior walls. We see this constantly in the historic district and along Main Street.
- Construction debris left from renovations. Ellicott City homeowners renovate older homes frequently, and drywall dust, sawdust, and even pieces of framing end up in open return ducts during the job. Once the system runs, that debris gets pulled deeper into the trunk lines and blower.
- Finished basements with hidden register counts. A finished basement in a Dorsey Hall colonial often adds 6 to 10 registers to the system. A phone quote based on the main floor count misses these entirely, which is exactly why we count registers in person before we quote.
- Skipped air handlers and blower motors. Some crews clean only the duct runs and leave the blower motor, housing, and evaporator coil untouched. The system then pulls dust from the air handler right back into the clean ducts. In Ellicott City especially, where many homes run HVAC for long spring and fall shoulder seasons, blower cleaning matters.
Pricing for Air Duct Cleaning in Ellicott City, MD
Most standard Ellicott City homes run $395 to $795 for a complete duct cleaning, including the supply and return sides, trunk lines, plenums, and air handler. Smaller condos and townhomes near Turf Valley or Route 40 can land around $350, while larger colonials with finished basements and multiple systems run higher, sometimes $900 or more. What changes the price is system size, the number of registers, and whether the return side needs significant disassembly for access. We provide a written, flat price before any work begins, and the estimate is free. Call (737) 727-2314 for an exact quote on your Ellicott City home.

FAQs About Air Duct Cleaning in Ellicott City
Every 3 to 5 years for most Ellicott City homes, assuming no major renovation, no water event, and no chronic dust or allergy issues. Homes with pets, older systems, or recent interior work may need cleaning sooner. We won’t tell you to clean ducts that don’t need cleaning. If a camera inspection shows a thin layer of normal dust and no debris, we’ll say so and suggest you wait. Call (737) 727-2314 to talk through your situation.
One flat price per system, written down before any work starts. We count your registers during the in-person walkthrough, then give you a single number that covers the entire job. That number does not change at the door. We don’t do per-vent pricing because it enables the bait-and-switch that our trade is unfortunately known for.
Yes. Every Ellicott City job includes before-and-after camera inspection of your duct interiors. You’ll see the condition of the trunk line and return drop before we start, and you’ll see the same runs after cleaning. The photographs are yours to keep, part of the Relay Standard booking experience. If we didn’t clean it, there’s no photo of it.
No, and we’d rather be honest than quick. A proper duct cleaning in Ellicott City takes 4 to 7 hours, and we don’t cut corners to squeeze it into a shorter window or promise a same-day visit that becomes a rushed job. We’ll give you a real arrival window and a written price, and we’ll do the job right the first time. Schedule ahead, and call (737) 727-2314 to book.
Most Ellicott City homes do well with a MERV 8 to MERV 11 filter after a professional cleaning. Higher ratings like MERV 13 capture more fine particles, but they also add resistance, which older systems near the Patapsco valley may not handle well. We stock Honeywell, Aprilaire, and Guardsman filters and can recommend the right rating for your specific system at the end of the job. Call (737) 727-2314 and we’ll walk you through it.
