How Much Does Air Duct Cleaning Cost in Washington, D.C.? [2025 Data]

You can expect to pay $317 on average for duct cleaning in Washington, D.C., but it prices range from $231 to $433. Clean ducts mean clean air, but they also ensure smooth passage from your HVAC system into your living space. Dirty ducts contribute to slower airflow and put a strain on your energy bills, as well as resulting in lower-quality air. Learn why you should have your ducts cleaned regularly—and how much it’ll cost. 

Air Duct Cleaning Cost Factors 

Air duct cleaning costs in Washington, D.C., depend mostly on size elements: total duct square footage and the number of vents. After that, the materials, labor, inspections, and more impact the price. 

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 air 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 to $440. 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.

Air Duct Cleaning Pro Costs

As you budget for air duct cleaning, you’ll need to consider the pro you hire, their expertise level, licensing, and what their schedule looks like. 

Labor in Washington, D.C.

The capital is a unique place, so while it’s the political center of the country, some trades like duct cleaning are actually more affordable than in other places. Just be aware that after-hours work will cost at least 50% more than if you were to schedule the work during regular work hours. 

Licensing

Washington, D.C., requires HVAC work to be performed by a licensed HVAC technician. There are a few levels of experience and training for these pros: apprentice, journeyperson, master, and contractor. For duct cleaning jobs, hiring a journeyperson and master pro is the best route. The work can affect the safety of your air quality, so consider hiring someone above an apprentice level. 

Tipping

Tipping 10% is what we recommend for pros who go above and beyond, but this isn’t the norm. D.C. is a city where people tend to know each other, so if you loved the service you got, it’s not a bad idea to tip. However, we still recommend only doing so if the service was excellent. 

Additional Pros to Consider Hiring 

If you’re thinking about hiring a different pro for the job, keep the following in mind. 

General Contractor 

Hiring a duct cleaning pro will cost about the same as what general contractors charge per hour. A general contractor could inadvertently come across the fact that your ducts need cleaning and may offer the service. 

However, you need a licensed HVAC pro to perform this work in D.C., and some general contractors won’t have this license. This will most likely cause problems if you need to exercise your home insurance policy or call in a warranty. 

Does Air Duct Cleaning Increase Home Value?

Air duct cleaning will help preserve your existing home’s value, but it won’t increase it. This isn’t necessarily bad news for homeowners, though, as duct cleaning can be used to show prospective buyers or appraisers that you care for your home well, making it more marketable and potentially giving you more power during price negotiations. 

Something to mention is that while duct cleaning isn’t expensive compared to other home maintenance projects, if a home inspector or buyer discovers that your ducts need cleaning, they’ll likely try to lower their bid by at least three times the value of the cleaning itself. Talk to an air duct cleaner in Washington, D.C., to make sure your house is up to scratch.
