How Much Does Air Duct Cleaning Cost in Baltimore?

Air duct cleaning in Baltimore typically costs $350 to $750 for a standard single-family home, with most rowhouses landing between $400 and $550. Larger detached homes in neighborhoods like Roland Park or Mount Washington, or systems with heavy buildup, often run $800 to $1,200. Dryer vent cleaning is a separate job and usually runs $110 to $195.

That range covers a full supply-and-return cleaning with a written price before any work starts. What moves you up or down the scale is the size of your system, how many vents you have, and how much has collected since the last cleaning. Below, we break down each line item so you can plan a realistic number before you pick up the phone.

Air Duct Cleaning Cost Breakdown (2026)

Here’s how Baltimore pricing breaks down by the work involved. These ranges reflect what we see quoted across the city in 2026, not national averages.

What pushes a Baltimore job toward the top of the range? Age of the home matters more here than in most cities. A lot of Baltimore housing stock went up before 1950, and those homes often have original ductwork with more joints, more turns, and more places for dust to settle. We see this constantly in Charles Village and Hampden, where plaster walls and older boot connections make a cleaning take longer than the same square footage would in a newer build.

Vent count is the other big driver. A 1,200-square-foot rowhouse might have eight vents. A 2,800-square-foot detached home in Homeland could have twenty. That difference alone can double the price, because every vent has to be individually attached, brushed, and pulled. If you’re comparing quotes and one is dramatically lower than the rest, ask how many vents it covers. That’s usually where the gap lives.

You’ll also pay more if your system hasn’t been touched in a decade, or if you’ve just finished a renovation. Drywall dust and sawdust travel through return air fast, and once it coats the interior of the ducts it takes more passes and stronger equipment to clear. That’s the kind of work a Rotobrush or Nikro setup handles well, and it’s why we bring professional-grade gear rather than shop vacuums. For a closer look at what a full visit involves, see our home page overview.

What Affects Air Duct Cleaning Pricing in Baltimore

Six things move the number most:

• Home size and vent count. Most Baltimore quotes are built per vent after a base rate. A Canton rowhouse with nine vents and a Pikesville colonial with twenty-two are two different jobs, even if the square footage is close.
• Number of HVAC systems. Two-zone homes have two air handlers and two sets of trunk lines. Each system gets cleaned separately, so the price adds up. This is common in newer construction out toward Owings Mills.
• Access and layout. Finished basements with ceiling access are quick. Tight crawl spaces, low attic clearances, or ducts boxed behind plaster take longer and cost more. Older homes near Fells Point and Federal Hill often have this challenge.
• How long since the last cleaning. A home cleaned three years ago needs a lighter pass. One that’s never been cleaned in twenty years may need two.
• Duct material and condition. Flex duct cleans differently than rigid metal. If sections are crushed, disconnected, or lined with deteriorating insulation, we’ll point that out and quote repair separately.
• Add-ons you choose. Sanitizing, microbial treatment, and dryer vent cleaning are optional. They’re priced clearly up front, never tacked on at the end.

One thing that doesn’t affect our pricing: how many pets you have or how much dust you can see. We quote before we start, and that number holds whether the job takes three hours or five. No surprise line items on the invoice, ever.

Why Baltimore Ducts Get Dirty Faster Than You’d Expect

Baltimore sits in a humid subtropical zone with four real seasons. That means your system runs heat for months in winter and air conditioning for months in summer, and both push air through the same ducts. Every season change stirs up what settled during the last one.

Spring is the worst stretch. The city gets heavy pollen in April and May, and it comes in through open windows, then gets pulled straight into return vents. If you have a dog that sheds, that pollen binds to pet hair and settles along the duct floor. We see this most in neighborhoods with mature tree canopy, like Bolton Hill and Guilford. By late May, those systems are carrying more debris than they were in February.

Older Baltimore homes also tend to have more basement moisture. A damp basement plus a leaky return can mean microbial growth inside ductwork. We don’t lead with scare talk about it. But if we find it during a cleaning, we’ll show you photos and let you decide whether treatment makes sense.

Newer construction isn’t immune either. Homes in Canton and Brewer’s Hill built in the last fifteen years often have tightly sealed envelopes and flex duct runs. Less outside air means whatever’s inside recirculates more, so filters load up faster and ducts hold onto debris longer.

How Much Does Dryer Vent Cleaning Cost in Baltimore?

Dryer vent cleaning in Baltimore runs $110 to $195 for a standard roof or wall vent, and most homes fall right around $145. It’s the most overlooked safety item in a house, and it’s also one of the cheapest services we offer.

Why it matters here: many Baltimore rowhouses have long, winding dryer vent runs that push through interior walls and up to the roof. The longer the run, the more lint catches on the ridges. We clear the full length, not just the first few feet, and we check the exterior termination to make sure the flap isn’t stuck or screened over. If your dryer takes two cycles to dry a load, that’s the usual sign.

Bundle it with a duct cleaning and you’ll typically pay $425 to $650 total instead of booking two separate visits. If you’re already scheduling one, it’s worth adding the other while the equipment is set up.

How to Save on Air Duct Cleaning

You don’t need to chase the cheapest quote. In our experience, the lowest bid in Baltimore is often the one that skips the return side, uses a shop vac instead of a Rotobrush, or adds charges once the crew is inside. A few practical ways to keep the number reasonable:

• Know your vent count before you call. Walk the house and count every supply and return register. It takes five minutes and gets you a more accurate quote on the first call.
• Bundle services. Duct cleaning plus dryer vent cleaning in one visit usually saves $30 to $70 compared to booking them separately.
• Book in the shoulder seasons. Late fall and early spring are our quietest stretches in Baltimore. Scheduling then can mean more flexibility and, sometimes, better pricing than the peak summer rush.
• Skip add-ons you don’t need. Sanitizing and microbial treatment are only worth it if there’s visible growth or a specific concern. We’ll tell you honestly if we think you can skip them.
• Get a written price first. Any company that won’t put a number in writing before starting isn’t one to hire. A written price is standard with us on every visit.

Is It Cheaper to Repair or Replace Ducts?

Repair is almost always cheaper, and usually the right call. Damaged duct sections in a Baltimore home typically run $250 to $900 to repair, while full duct replacement can run $2,500 to $7,000 depending on the size of the house and how much is accessible.

Here’s the honest version: most homes we see don’t need replacement. Sealing and repairing disconnected joints, crushed flex runs, and torn insulation usually solves the problem for a fraction of the cost. Replacement comes up when ductwork is undersized for the system, extensively water-damaged, or laid out in a way that can’t be fixed in place. We’ll show you photos of what we find and give you both numbers so you can decide.

Can you clean my ducts the same day I call?

Often yes, depending on the day and the neighborhood. Same-day slots come up most in the mornings, and we answer the phone 24/7 with a live person, not a machine. If we can’t get to you same day, we’ll offer the next available window and put the price in writing before we book. Call (323) 918-4345 to check today’s availability.

Is air duct cleaning worth it for an older Baltimore rowhouse?

Usually yes, especially if it’s been more than five years since the last cleaning. Older rowhouses in neighborhoods like Butchers Hill and Highlandtown often have original ductwork with more joints where dust settles. A cleaning typically runs $400 to $550 for these homes. If your system hasn’t been touched since you moved in, it’s worth a look. Call (323) 918-4345 for a free estimate.

Do you charge extra for pets or heavy dust?

No. We quote a flat price based on vent count and system size, and it doesn’t change because you have two dogs and a toddler. A standard Baltimore cleaning is $350 to $750, and that number is written down before we start. We use pet-safe product choices where available and keep tools quieter during nap hours. Call (323) 918-4345 to schedule.

How often should ducts be cleaned in Baltimore?

Every three to five years for most homes, and every two to three if you have pets, allergies, or a home older than 1960. How Much Does Air Duct Cleaning Cost in Boston, MA? (2026 Price Guide) Baltimore’s pollen season and long heating season both push debris into the system faster than in milder climates.

What’s Included at Every Price

The price on your written estimate covers more than the cleaning itself. Every visit includes shoe covers and drop cloths from the moment the crew walks in, so floors and furniture are protected. Every technician is background-checked and arrives in uniform, working to the Cedarwell C.A.R.E. values. We use professional equipment from Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman, not entry-level rental gear that leaves half the debris behind.

And when the job is done, you get a photo of the clean-up before the crew leaves. That’s not marketing language. It’s the same standard we hold on every job, stamped with the 365-Day Done Right Promise: if it isn’t right, we make it right. Morton’s has been part of the Cedarwell family of companies since 2005, and every location is independently owned and held to the Cedarwell Care Promise.

What to Check Before You Hire Anyone in Baltimore

Whether you hire us or someone else, four things separate a careful company from a rushed one:

• A written price before work starts. Not a verbal range. A number on paper.
• Proof of insurance. Any legitimate Baltimore duct cleaning company will provide it on request.
• A real person on the phone. If you only reach voicemail or a chatbot, you won’t reach anyone when something goes wrong.
• A clear clean-up standard. Shoes covered, floors protected, and a photo of the result. If a company can’t tell you what they’ll protect and how, that’s your answer.
