How Much Does Air Duct Cleaning Cost in Baltimore? [2025 Data]

Baltimore, Maryland, homeowners battle air quality issues in the city and often deal with older homes—a perfect recipe for dirty ducts. You can expect to pay $368 on average, but it commonly ranges from $242 to $496. Having clean ducts ensures that your HVAC system is working correctly. Other than heating and cooling systems working efficiently, clean ducts mean cleaner air. Learn what makes up the total cost of this often overlooked project. 

Air Duct Cleaning Cost Factors 

Duct size, number of vents, and who you hire will all influence the cost of a duct cleaning in Baltimore, MD. Some other factors, like time of year and the age of your home, also come into play. It’s important to know how these factors influence cost so you understand what you’re paying for. Take a look below to get a better idea of what you’ll pay. 

Total Square Footage of Vents

The more ductwork you have, the more you'll pay for cleaning. Some local air duct cleaners base their price on the property’s square footage since the larger your home is, the more ductwork you'll have.

The cost of cleaning ductwork is $0.15 to $0.30 per square foot. So, to clean vents in a 1,500-square-foot house, expect to pay between $200 and $450. Here’s a breakdown of the average air duct cleaning costs based on the size of your home:

Number of Vents

As with ductwork, the more vents you have, the more it’ll cost to clean them. On average, vents cost $35 each to clean, with most homeowners paying between $25 and $50 per vent. To get a ballpark estimate for the cost of vent cleaning, count the vents in your home and multiply that by $35.

Here’s how the number of vents affects your air duct cleaning cost:

Type of Ductwork

If you have flex ducts, expect to pay toward the upper end of the range. Unlike metal ducts, flex ducts require special cleaning equipment, so you’ll pay more to clean them. Rigid metal ducts are easy to clean with a vacuum, air hose, or power brush, so they cost less to clean.

Labor Cost

Most ductwork pros charge by the hour, with duct cleaning services priced between $90 and $125 per hour. Depending on the size of your home, the type of ductwork you have, and how accessible the ducts are, most cleaning jobs require three to eight hours of labor.

Accessibility

If you ensure that vents are easy to reach with vacuuming equipment, accessibility shouldn’t be a problem. But some ductwork designs make accessing them difficult, especially if you don’t have floor vents. If air duct technicians have to work harder or take additional steps to reach your vents, it can result in additional labor charges.

Inspections

Some vent problems, like noticeable mold or nests, don’t require an inspection before cleaning. However, if you aren’t sure about the state of your vents, consider arranging a professional inspection. These inspections are often bundled together as part of an HVAC inspection, which costs an average of $300 but can fall under $100 for simple systems.

Level of Cleanliness or Contamination

Duct cleaning is offered as a package with set labor costs, but extremely dirty jobs will cost extra. If the ducts have never been cleaned and need a lot of work to remove dust and buildup, expect additional fees.

Weather

Don’t hire for this job in the middle of July or January if you want the best work at the best price. Professional HVAC workers don’t like to be out in the humidity or snow any more than you do, so if they will be working in those conditions, you’ll pay a premium. The good news is this work isn’t often urgent, so schedule the project during periods where the weather outside matches your preferred indoor temps. 

Air Duct Cleaning Pro Costs

Labor in Baltimore

The cost of living in Baltimore, which is moderately high, doesn’t always line up with local salaries. Because of this, expect a wide range of quotes from pros. Remember, they will charge more if they need to work through snow or blinding heat, have to travel a far distance to your home, or need special tools to perform the work. 

Licensing

Baltimore requires HVAC work to be performed by a licensed HVAC technician. Getting this license isn’t easy (journeyman level requires four years as an apprentice with over 6,000 training hours). A pro might say they are licensed, but ask which level. It matters when it comes to insurance and warranty, so double-check this before continuing. 

Tipping

We recommend tipping 10% for pros who go above and beyond, but this isn’t the norm. You should really only tip if you’re extremely happy with the service. This can mean a pro working after hours, adding on services and not charging you extra, or cutting you a bit of a deal on the price. 

Contact a Baltimore air duct cleaning pro to inquire about pricing structure and availability. Don’t be afraid to talk to a few different outfits in order to average out your quotes. 

General Contractor 

Hiring a duct cleaning pro will cost about the same as what general contractors charge per hour, so we don’t recommend it. However, a general contractor may inadvertently discover that your ducts need cleaning and offer the service. 

Proceed with caution here—while some general contractors can likely perform the work, they should be licensed to perform HVAC work in Baltimore. This process takes four years as an apprentice and is a requirement, so cover your bases and make sure your pro has the required paperwork. 

Does Air Duct Cleaning Increase Home Value?

Cleaning your air ducts will preserve your home value, but it won’t increase it. If you’re planning on selling, know that Baltimore buyers expect air ducts to be in good condition if they’re going to offer the asking price. Having clean ductwork also signals that you’ve taken care of your home, allowing more power in negotiation. 

The schedule for having your air ducts cleaned depends on the home, but it’s a good idea to perform this service if you haven’t done it within two years of listing your home for sale. While the price to have your ducts cleaned is only a few hundred dollars, buyers may use clogged or dirty ducts to talk you down, sometimes to the tune of thousands.
