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 Baltimore
Air duct cleaning in Baltimore typically costs between $350 and $650 for a standard single-system home, and the job usually takes 3 to 5 hours.

We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we serve the entire Baltimore metro from our local office. Call (737) 727-2314 and a live person picks up, 24/7.
We know Baltimore’s housing stock because we’re in it every week: rowhouses in Canton, converted Victorians in Mount Vernon, ramblers out in Parkville. Older ducts behave differently than new construction, and pricing should reflect the system you actually have, not a national average that means nothing on the ground.
Why Cardinal Air Duct Cleaning Is Baltimore’s Preferred Air Duct Cleaning Company
Baltimore homeowners tend to ask sharper questions than most. That’s fair. The duct cleaning trade has earned a reputation for $49 bait-and-switch coupons that turn into $900 invoices once the van is parked outside. We run the opposite model.
Every booking with Cardinal includes The Relay Standard: a live trackable arrival window, written price before work starts, before-and-after photos of your own ducts, and a digital invoice you can pay from a link on your phone. No clipboard math at the door. No per-vent surprises after the equipment is already rolling. You’ll know your technician’s name before they ring the bell, and they’ll arrive in uniform with Rotobrush agitation tools and Nikro HEPA extraction units, not a rented shop-vac.
Omar Haddad leads our Baltimore team. He set the local standard back when duct cleaning was still done with whatever was on the truck, and he’s the reason our 365-Day Done Right Promise applies to every job without exception. If the work isn’t right within a full year, we return and correct it at no charge. That’s not a sales line. It’s the longest-standing satisfaction window in the trade.
HVAC Duct Cleaning in Baltimore
HVAC Duct Cleaning in Baltimore usually means cleaning the full supply-and-return network connected to a forced-air furnace or heat pump: main trunk lines, branch runs, registers, the air handler cabinet, and the blower motor assembly. In Baltimore’s older homes, that last part matters more than most contractors admit, because decades of rust-scale and lint settle inside the blower and recirculate through every register. A complete HVAC duct cleaning here runs $350 – $650 for a typical single-system Baltimore home, depending on system size, number of returns, and how much buildup sits inside the air handler.
Supply and Return Duct Cleaning
Supply ducts push conditioned air out to your rooms. Return ducts pull air back to the furnace. They get dirty differently. In Baltimore rowhouses, return ducts often pull air through unfinished basements, which means they collect lint, rust particles, and whatever the last three renovations left behind. We clean both runs under negative pressure, so debris goes into a HEPA-filtered Nikro vacuum, not back into your living room.
Full System Cleaning with Video Inspection
Before we start, we run a camera through the main trunk line and problem branches. On Baltimore homes with original galvanized ductwork, this step catches loose joints, collapsed flex runs, and rusted-through sections that no amount of brushing will fix. You see the photos after. When we recommend sealing or minor restoration work, there’s a written quote and you decide before anything extra happens.
Vent Cleaning in Baltimore
Vent Cleaning in Baltimore means cleaning the visible register and grille openings plus the first several feet of duct behind them, where most dust, pet hair, and household lint accumulate. It’s not a substitute for full-system cleaning, but it’s the right call when the system is otherwise sound and the buildup is localized. Vent cleaning in Baltimore typically runs $180 – $300 as a standalone job, and a thorough clean takes about two hours for an average home.
Register and Grille Restoration
Older Baltimore homes have stamped-steel registers that rust from years of condensation and coastal humidity. Sometimes they’re painted shut. We pull them, degrease and clean them, and reset them with new screws where needed. If a register is beyond saving, we’ll tell you before we touch it and point you to a local supplier rather than charging you for a replacement you could buy yourself.
Clearing Blocked Branch Runs
A single branch run can be choked with construction debris from a renovation, or with lint if a dryer vent was incorrectly tied into an air duct. We identify blocked runs with the camera and clear them with Rotobrush agitation, then verify airflow before we leave. You get before-and-after photographs of that specific run, not a generic shot from someone else’s house.
Trusted Brands We Service in Baltimore
We service all major HVAC and filtration brands across Baltimore, including Honeywell, Aprilaire, and Guardsman filtration systems. Our trucks carry Abatement Technologies containment equipment to protect your home from cross-contamination during cleaning, along with replacement filters for the most common Baltimore installations. That means when we find a badly clogged Aprilaire media filter or a failed Honeywell electronic air cleaner cell, we can often handle it the same visit without making you wait on a parts order.
Common Air Duct Cleaning Problems We See in Baltimore Homes
- Rusted galvanized trunk lines in pre-1950 rowhouses: Baltimore’s original ductwork was built when furnaces were gravity-fed and filters were an afterthought. Rust-scale breaks loose inside the trunk and blows fine orange dust through every register. Cleaning helps, but sealing failing joints is what actually stops the dust.
- Collapsed flex runs behind finished basement ceilings: Homeowners in neighborhoods like Hamilton and Lauraville often finish their basements, which means old flex duct gets hidden behind drywall and crushed. We spot these with the camera before they become a full system failure.
- Dryer lint pulled into return ducts: Several Baltimore homes we’ve visited had dryer exhaust improperly vented near a return register, pulling lint into the supply system. That’s a fire hazard and an air-quality problem, and it should be corrected during any duct cleaning.
- Filter cabinets that can’t accept modern media: Many Baltimore systems have a 1-inch filter slot. Modern MERV 13 filters in a 1-inch slot add a lot of resistance, which pulls more debris into the system rather than less. We explain this clearly and recommend the right filter setup for your actual system, not whatever has the best marketing.

FAQs About Air Duct Cleaning in Baltimore
Most Baltimore rowhouses need full air duct cleaning every 3 to 5 years, not every year. If you have pets that shed heavily, you burn candles often, or you’ve just finished a renovation, you may need it sooner. If your ducts were cleaned properly less than two years ago and nothing has changed, you probably don’t need us yet. The honest answer is that most homes don’t need annual cleaning, and we won’t tell you otherwise. Call (737) 727-2314 and describe your situation, and we’ll give you a straight recommendation.
We charge per system, not per vent. Never per vent. Many Baltimore homeowners have been quoted a low per-vent rate, then watched the invoice climb because the air handler, blower motor, and plenum were each counted separately. With Cardinal, the quote covers the entire system including the air handler and blower, and it’s written and signed before we start. Call (737) 727-2314 for your all-in price.
Yes, and we do it regularly in Baltimore homes built before 1950. Rusted galvanized ductwork needs more than a brush; we inspect with a camera, clean under negative pressure with HEPA filtration, and seal failing joints with mastic where needed so the rust doesn’t keep shedding into your air. The sealing work is quoted separately and approved by you before anything happens. In a 1920s rowhouse off Read Street, our tech found the return ducts pulling air through a rusted galvanized trunk line in the basement, blowing fine rust-scale and lint dust through every register on the second floor. We ran agitation tools and a HEPA filtration unit under negative pressure, then sealed the failing joints with mastic, and showed the homeowner before-and-after photographs of the inside of the main supply trunk. The difference was visible without any measurement.
You’ll see before-and-after photographs of your own ducts, taken with a camera before we begin and after we finish. We photograph the main trunk line, any runs that had heavy buildup, and the air handler and blower assembly. These are your ducts, not stock photos. If you want to watch the camera feed live, you’re welcome to. That’s part of The Relay Standard and it’s not optional for our technicians. Call (737) 727-2314 to schedule.
Dryer vent cleaning is a separate service from air duct cleaning, and it should be. Dryer vents carry lint and moisture to the outside of your home; air ducts carry conditioned air through your living space. Mixing them up or treating dryer vent cleaning as a free add-on is how some companies pad the bill. We offer both services in Baltimore, and we’ll tell you plainly which one you actually need. If your dryer vent hasn’t been cleaned in more than two years, it’s due regardless of your air ducts. Call (737) 727-2314 and we’ll quote both honestly.
Straight Answers About Air Duct Cleaning in Baltimore
We’ll say it plainly because most companies won’t. Not every Baltimore home needs air duct cleaning right now. If your system was properly cleaned within the last few years, you have good filtration, and you’re not seeing dust build up quickly on registers or furniture, you can wait. But when you do need it, you need a company that charges one flat price per system, shows you photos of your own ducts before and after, and stands behind the work for a full year. That’s what we do.
