Air duct cleaning costs $388 on average, but can range between $150 and $800. Air ducts play an essential role in your home’s air quality. Without them, air can’t circulate through your home. And since ducts filter out the impurities before we breathe anything in, cleaning them is necessary to combat the debris accumulated over time.
Let’s review the factors behind professional HVAC cleaning costs and how to budget your next project.
Air Duct Cleaning Cost Factors
The price you'll pay to hire someone to clean your air ducts depends on the size of your home and ductwork, accessibility, and labor costs in your area.
Adam conducted an air duct cleaning on my 3-ton system, which included cleaning seven ducts, along with the return duct. During the service, he discovered that the blower was not functioning due to a faulty capacitor. He also showed me the clogged filter and took the time to explain the importance of changing the filter every 2-3 months. He replaced the capacitor at a reasonable price, particularly when compared to quotes from other companies I had contacted. Moving forward, Adam will be responsible for maintaining my system, as he provided valuable insights that I had not received from my previous HVAC service providers.
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, based on the theory that 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 typical 1,500-square-foot house, expect to pay between $180 and $360.
Here’s a breakdown of the average air duct cleaning costs based on the size of your home:
| Size (Square Feet) | Average Cost |
|---|---|
| 1,000 | $140–$250 |
| 1,200 | $180–$360 |
| 1,500 | $225–$450 |
| 2,000 | $300–$600 |
| 3,000 | $450–$900 |
Air duct cleaning takes an average of five to seven hours for most households. You can make the job go quicker by removing any obstacles around your HVAC entry points, like furniture, to make it easier for your pro to access the ducts.
Number of Vents
As with ductwork, the more vents you have, the more it’ll cost to clean them. Typically, 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:
| Number of Vents | Cost |
|---|---|
| 8 | $200–$400 |
| 12 | $300–$600 |
| 16 | $400–$800 |
| 20 | $500–$1,000 |
Type of Ductwork
If you have flex ducts, expect to pay toward the upper end of the range. Unlike metal ducts, flex ducts require specialist cleaning equipment, so this service commands a higher price. Rigid metal ducts are easy to clean with a vacuum, air hose, or power brush, so they tend to cost less to clean.
Labor Cost
Most ductwork pros charge by the hour, with duct cleaning services typically 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 may 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 for an honest assessment. These inspections are often bundled together as part of a 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.
Household Habits
Some living situations are harder on ductwork than others. A house where people frequently smoke will lead to dirtier ductwork that you will need to clean more often. In addition, a house with several pets can create a lot of dander and hair that flows into your air vents, meaning your ducts may need more attention.
Air Duct Contamination Removal Costs
Dealing with any pest, asbestos, or mold contamination will add to your air duct cleaning costs. Here’s the cost breakdown for different air duct contamination removal services:
| Service | Price Range |
|---|---|
| Pest removal | $200–$1,200 |
| Mold and mildew removal | $1,100–$3,400 |
| Asbestos removal | $5–$20 per square foot |
Pest Removal: The cost of hiring a pest control service ranges from $100 to $260, while the cost of rodent removal runs from $200 to $1,200.
Mold and Mildew Removal: If you have mold in your air ducts you’ll need to add mold remediation costs to ensure your home’s air is safe to breathe.
Asbestos Removal: Removing asbestos costs $5 to $20 per square foot. If your duct cleaning pro sees asbestos in the ducts, they won't be able to resume work until it’s removed.
Common Air Duct Cleaning Cost Add-Ons
Certain add-on services can ensure that you avoid ending up with dirtier-than-usual air ducts or costlier problems on your hands down the line.
Video Inspection: An air duct inspection can determine how dirty they are and other potential problems. Most people pay between $70 and $130 for a video inspection, but this service can also be bundled with an annual HVAC inspection package.
Preventative Sprays: Applying sprays or coatings is a common add-on service to maintain duct health after a cleaning. This step isn’t necessary, except in cases of mold. Sprays include deodorizers, disinfectants, and fungicides.
Furnace Cleaning: Many top HVAC-cleaning companies will combine air duct cleaning with other HVAC services, such as cleaning related parts around your furnace. Cleaning your furnace filters, vent covers, and related ductwork will cost $60 to $150 per furnace. Your HVAC pro will also take a moment to inspect items like wiring, burners, and valves.
Air Conditioning Repairs: Imbalances and faulty parts in your central air conditioner can lead to condensation and mold in your air ducts. AC repairs cost $350 on average, but major part replacements can cost thousands. Fixing a leak will cost between $220 and $1,600, whereas replacing the air handler can cost as much as $5,600.
Air Conditioner Maintenance: Annual AC maintenance can ensure that your system efficiently cools your home. On average, a basic AC tune-up costs between $75 and $200, though there are some tasks you can complete on your own for less. For example, you can change your AC filter in minutes or install a new thermostat for the cost of parts and basic household tools.
Dryer Vent Cleaning: If you incorporate dryer vent cleaning with your air duct cleaning service, it'll cost about $100. As a standalone service, dryer vent cleaning costs between $100 and $170. While seemingly minor, a clean dryer vent boosts appliance efficiency, enhances drying performance, and reduces fire risk.
Air Duct Coating: On average, coating air ducts costs $180 to $630. The pro applies a protective substance to the inside of the ductwork to prevent dust and grime particles from circulating back into your home.
Air Duct Repairs: Repairing air ducts costs $200 to $800. During a video inspection or a cleaning service, your pro may spot issues that need attention. If you catch these issues early, they'll cost less than if you wait until they're a significant problem. Plus, if your air ducts need repair, they won't perform as efficiently, costing you more in energy consumption.
Cleaning an Air Duct Yourself vs. Hiring a Professional
If you choose to clean your home’s air ducts yourself, you’ll need a few supplies and some prior knowledge of the air duct system. The most expensive tools to buy are the ladder and vacuum, which can cost between $100 and $400, depending on the brand. Everything else, such as goggles, a bristle brush, masks, and rags, will cost $10 to $30.
You could save between $200 and $500 if you opt to clean the air ducts yourself. Although you may save some money, hiring a professional guarantees a job well done.
Local air duct cleaners will use tools specifically designed for the job. A shop vacuum would be ill-equipped to handle the work, and other tools may cause damage to your ductwork.
How to Save Money When Cleaning Air Ducts
If air duct cleaning costs feel a little stiff, there are a few ways to reduce what you’ll pay for the service and how often. For instance, you can:
Vacuum around duct openings, registers, vent grills, and the furnace routinely
Change air filters every few months
Use a home air purifier system
Clean AC coils regularly
Have ducts inspected annually
Do extensive research on duct cleaning professionals

The Environmental Protection Agency (EPA) states that there's no conclusive evidence to show that dirty or dusty air ducts increase dust and airborne particles in your home or pose any risk to your health. On the other hand, your air ducts require cleaning if there's any mold or mildew, you have a rodent or insect infestation, or you have clogged ducts. Regular air duct cleaning will also extend the life of your HVAC system, leading to less frequent repairs and preventing premature replacement in the future.
Spring and fall are the most popular seasons for duct cleaning. Many often focus on spring cleaning and pre-winter home tasks to get ready to turn on their AC or heater. However, there is no wrong time to hire an HVAC pro to clean your air ducts, and you may even save some money by hiring them when they are in less demand. Just remember that they will need to turn your system off for several hours when cleaning, so it's best not to book it on freezing cold or scorching hot days.
Professional air duct cleaning takes two to five hours, depending on the size of your home and the extent of the cleaning. The ductwork in standard homes with total square footage of 1,500 to 2,000 will take closer to two hours. Larger homes with extensive return and supply ductwork—often over 3,000 square feet—can push up to five hours. Keep in mind that related cleanings and repairs in your HVAC system will add to this total and may require two visits.
You won’t have to do much to prepare for air duct cleaning. Make sure your vents are easy to access, and move any nearby furniture or other objects out of the way. If you have a furnace or air conditioner unit, ensure they are easily accessible. And if you have a pet, make plans to get them out of the house, if possible. Vent vacuuming can be loud and requires access to all rooms, so you may want to take extra steps for pet safety.
The EPA claims ducts only need cleaning if the above signs become an issue in your household. But the NADCA states that you should clean your air ducts every three to five years to prevent any problems with your HVAC system.
Because air ducts can irritate those with asthma or respiratory issues, you’ll need to consider your health situation to decide if this is worth the expense. (Hint: It usually is.)
