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 Air Duct Cleaning Across Dundalk
Most standard air duct cleanings in Dundalk run $350 – $650 for a typical rowhouse or bungalow, and the work is usually done in a single scheduled visit. That price covers the full system: supply ducts, return ducts, the blower compartment, and the air handler. You get a written price before any work starts, and you get before-and-after photos of your own ducts so you can see exactly what we removed. Call (737) 727-2314 for a free estimate.
Our crews work Dundalk neighborhoods every week: Turner Station, Old Dundalk, Gray Manor, St. Helena, and up along Merritt Boulevard and Wise Avenue. We know these houses. The WWII-era rowhouses and 1950s-70s brick bungalows that dominate the Erdman Avenue and Dundalk Avenue corridors share a common duct profile: original galvanized trunk lines, cut-in wall registers, and decades of fine grit that a camera inspection almost always confirms.
Why Cardinal Air Duct Cleaning Is Dundalk’s Preferred Air Duct Cleaning Company
Omar Haddad leads our Air Duct Cleaning team, and he sets the standard for how every Dundalk job runs. Every booking includes the Relay Standard: a live trackable arrival window, before-and-after photos of your ducts, and a digital invoice you can pay from your phone. No vague estimates. No price shifts once the technician is inside.
Part of the Relay Home Co. family since 2005, Cardinal Air Duct Cleaning operates on one rule: a written price before a single duct is touched. Our techs are background-checked and uniformed. You know the technician’s name before they open the door. They run Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units. That’s not truck-mounted shop-vac work.
Every job is backed by 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’s the longest-standing satisfaction window in the trade, and it applies to every booking without exception.
Air Duct Inspection in Dundalk
An air duct inspection in Dundalk typically runs $99 – $199, and we credit that full amount toward the cleaning if you book the job. We run a camera through your main trunk line and returns, then show you the footage on the spot. You see what’s actually in there before deciding anything. For Dundalk homes near the Patapsco River and the port, that footage usually shows a fine gray-brown silt packed along the duct seams, plus residue from decades of oil-furnace operation.
Dundalk sits at the mouth of Baltimore Harbor. The heavy shipping traffic and port-adjacent industrial activity give the air here a distinctive grit that settles into ductwork faster than in neighborhoods farther inland. A camera inspection is the only honest way to know whether your ducts actually need cleaning or whether the issue is something else entirely, like a blower motor out of balance.
Video Inspection Process
Our technician runs a flexible camera probe through the supply trunk and return duct. You watch the live feed in real time. We mark the problem areas, explain what the buildup is, and give you a written recommendation with a flat price before any cleaning begins.
When to Schedule an Inspection
Schedule an inspection if you’ve lived in your Dundalk home more than three years and have never had the ducts cleaned, or if you run a forced-air oil furnace and notice a new film of dust on registers within days of changing the filter. That’s a sign the blower compartment is holding debris. An inspection tells you exactly what’s going on.
Residential Air Duct Cleaning in Dundalk
Residential air duct cleaning in Dundalk generally runs $350 – $650 for a standard rowhouse or bungalow, depending on the number of returns and how much buildup sits in the main trunk. We quote one flat price per system, agreed before work starts. No per-vent pricing, no surprise add-ons. You know the number before the van pulls up.
Our techs clean the full pathway: supply ducts, return ducts, the air handler, the blower compartment, and the registers. We use negative-pressure extraction, meaning the loosened debris goes straight into the HEPA-filtered vacuum rather than back into your living room. That matters in Dundalk’s 1950s rowhouses, where the original trunk lines were never designed for the fine particulate that port air carries.
The 365-Day Done Right Promise covers every residential job. If the work isn’t right within a year, we return and make it right at no charge.
Supply and Return Duct Cleaning
Most buildup hides in the return ducts. In Dundalk homes with cut-in wall registers, the returns pull air from the dirtiest parts of the house: floors, pets, oil-furnace residue. We clean both supply and return runs completely, not just the visible registers. That’s the difference between source removal and a cosmetic pass.
Blower and Air Handler Cleaning
Oil furnaces in older Dundalk homes push a fine residue through the blower wheel and into the cabinet. If the blower compartment isn’t cleaned, that residue just reloads your new filter within two weeks. We remove and clean the blower wheel, scrub the housing, and vacuum the cabinet before we touch the duct runs.
Trusted Brands We Service in Dundalk
Dundalk homes run a mix of furnace brands, and we service them all: Honeywell controls, Aprilaire filtration systems, Guardsman reg products, and the original galvanized trunk lines found in most 1950s-era construction. We stock common replacement filters and register components, so turnaround on standard corrections is usually quick. If your system uses an Aprilaire filter housing or a Guardsman media cabinet, we’re familiar with both the drop-in dimensions and the airflow tolerances for Dundalk’s typical forced-air oil heat setups. Our equipment fleet is professional-grade: Rotobrush rotary brush systems for the trunk lines, Nikro HEPA vacuums for extraction, Abatement Technologies containment units when we’re working in finished basements or attached crawlspaces. The tools match the job, and the job matches the house.
Common Air Duct Cleaning Problems We See in Dundalk Homes
- Port-sourced fine grit packed into galvanized trunk lines. Dundalk’s waterfront position at the mouth of Baltimore Harbor means the air carries fine particulate from shipping traffic and port industry. It settles into ductwork along the seams and doesn’t come out with a standard filter change.
- Oil-furnace residue coating the blower wheel and air handler. Many Dundalk rowhouses run forced-air oil heat. Over years, that produces a sticky residue that clings to the blower wheel and throws it out of balance. Homeowners often think the furnace itself is failing when the real problem is years of buildup.
- Dirty duct work from home renovation projects. Dundalk’s housing stock has seen decades of DIY renovations, many of which happened without sealing the registers. Drywall dust, sawdust, and old insulation fragments end up in the duct runs and stay there. That’s not normal household dust. It requires source removal, not a brush pass.
- Pet dander and hair embedded in return duct liners. Dundalk is a pet-heavy community, and in older homes the return ducts often run through floor joists or wall cavities that collect dander and hair over time. A camera inspection shows it clearly, and the cleaning needs HEPA extraction to actually remove it rather than just stirring it up.

FAQs About Air Duct Cleaning in Dundalk
Every four to six years for a typical Dundalk rowhouse, and closer to every three if you run a forced-air oil furnace near the waterfront, have pets, or have done renovation work without sealing registers. The honest answer is that most homes don’t need annual cleaning. But a camera inspection will tell you exactly whether you’re in the four- or six-year camp. Call (737) 727-2314 and we’ll take a look.
We charge one flat price per system, agreed before work starts. Per-vent pricing lets a contractor drop a brush in each visible register and skip the main trunk and return ducts where the bulk of the buildup actually sits. With our system price, you get the supply runs, the return runs, the blower, the air handler, and before-and-after photos of your own ducts. The number doesn’t change once the technician arrives. If you want an exact quote, call (737) 727-2314 today.
Yes. Every Dundalk job includes before-and-after photos of your own ducts. You see the footage from the camera inspection before cleaning begins, and you see the after condition when we’re done. There’s no guesswork and no trust-me handshake. The proof is in the photos, and the 365-Day Done Right Promise backs it. Call (737) 727-2314 to schedule an inspection.
Yes. Cardinal Air Duct Cleaning specializes in air duct cleaning, HVAC cleaning, and dryer vent cleaning, and we can handle the ductwork and the dryer vent in the same scheduled visit. Dundalk rowhouses with laundry areas near the kitchen often have long, narrow exhaust runs that collect lint quickly. We’ll do both jobs in one appointment and give you one written price before we start. Call (737) 727-2314 to confirm a time.
No. We don’t promise same-day service because honest duct cleaning in Dundalk is a scheduled job, not an emergency dispatch. We schedule a specific arrival window that you can track live through the Relay Standard, and we show up when we say we will. You get a real appointment, not a four-hour window with a vague promise. Call (737) 727-2314 and we’ll set a firm time.
It involves source removal, not a brush pass. Our tech pulled the supply trunk in a 1952 brick rowhouse off Dunmanway and ran a camera through the main run: the galvanized duct interior was caked with fine gray-brown silt down to the seams, and the blower motor wheel was out of balance to the point the owner thought the furnace was failing. We set up negative pressure at the air handler, worked the trunk with agitation tools, and made two passes with HEPA filtration to capture the fine fraction before it could re-settle. The before-and-after photos of that homeowner’s own ducts went into their file, and their furnace went quiet. That’s the standard, and it’s what you get at (737) 727-2314.
