Air duct cleaning costs depend on your project and location. Check with a local pro for your specific job.
Professional air duct cleaning costs between $271 and $509 on average, with most homeowners spending around $390 for your service.
The size of your home and the number of vents you have are the primary factors that change your total project cost.
You should account for the cost of video inspections, furnace cleaning, dryer vent cleaning, and air duct repairs when you create your budget.
Hiring a local air duct cleaning professional keeps your HVAC system running efficiently and extends the life of your equipment.
In 2026, the national average cost for air duct cleaning is $390, based on 21,664 verified projects from Angi Pros. Most homeowners pay between $271 and $509, with home size, number of vents, and add-on services like dryer vent or furnace cleaning driving the spread. If your system needs repairs or a video inspection, your total could reach up to $800.
The price you pay to clean your air ducts depends on the size of your home and ductwork, how accessible your vents are, and labor rates in your area.
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.
Most local air duct cleaners charge $0.15 to $0.30 per square foot. Because overall pricing scales directly with the amount of ductwork in your home, larger spaces naturally require a higher budget. Here is how air duct cleaning costs break down by square footage:
| Size (Square Feet) | Average Cost in 2026 |
|---|---|
| 1,000 | $140–$250 |
| 1,200 | $180–$360 |
| 1,500 | $225–$450 |
| 2,000 | $300–$600 |
| 3,000 | $450–$900 |
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.
Vent count is a direct cost driver: each vent costs about $35 to clean, with most homeowners paying $25 to $50 per vent. To estimate your total, count the vents in your home and multiply by $35. The table below breaks down air duct cleaning costs based on the number of vents:
| Number of Vents | Average Cost in 2026 |
|---|---|
| 8 | $200–$400 |
| 12 | $300–$600 |
| 16 | $400–$800 |
| 20 | $500–$1,000 |
The type of ductwork in your home affects what you pay, with rigid metal ducts costing less because they clean easily with a vacuum, air hose, or power brush. Flex ducts require special equipment, which pushes the price toward the upper end of the range.
Ductwork pros charge $90 to $125 per hour, and most cleaning jobs take 3 to 8 hours, depending on your home's size, duct type, and accessibility.
Accessibility rarely adds cost when vents are easy to reach, but some ductwork layouts make access difficult, particularly in homes without floor vents. When technicians must work harder to reach your ducts, expect additional labor charges on your final bill.
If you’re unsure about the condition of your vents, a professional inspection gives you an honest assessment before cleaning begins. These are often bundled as part of an HVAC inspection, which averages $300 but can be as low as $100 for simple systems. Obvious problems, such as visible mold or pest nests, generally do not require a separate inspection before work starts.
Duct cleaning is typically offered as a package with set labor costs, but heavily soiled systems incur an extra charge. If your ducts have never been cleaned and require significant work to clear dust and buildup, expect additional fees beyond the standard package price.
Your household habits directly affect how quickly your ducts get dirty and how often they need cleaning. Frequent smoking leaves heavier residue in ductwork, while multiple pets contribute dander and hair that accumulates in your vents, both of which can increase your long-term cleaning costs.
Pest, mold, or asbestos contamination in your air ducts adds extra fees beyond standard cleaning. Pest removal costs $200 to $1,200, depending on whether it involves pest control treatment or full rodent removal, while mold and mildew remediation runs $1,100 to $3,400 to ensure your home's air remains safe to breathe. Asbestos removal costs $5 to $20 per square foot and must be completed before duct cleaning can resume—most contractors are legally required to halt work immediately if asbestos is discovered.
The table below compares average cleaning costs across three common air duct contamination types, along with key traits of each:
| Service | Price Range in 2026 | Key Trairts |
|---|---|---|
| Pest removal | $200–$1,200 | Price range reflects pest control treatment at the low end and full rodent removal at the high end |
| Mold and mildew removal | $1,100–$3,400 | Required to ensure safe indoor air quality; often paired with duct cleaning for full remediation |
| Asbestos removal | $5–$20 per square foot | Work must stop immediately if asbestos is discovered; removal required before duct cleaning can resume |
When scheduling air duct cleaning, certain add-on services help you avoid dirtier-than-usual ducts and more expensive problems later.
Video Inspection: $70–$130; can be bundled with an annual HVAC inspection package
Preventive Sprays: Cost varies by product; deodorizers, disinfectants, and fungicides are usually only necessary when mold is present
Furnace Cleaning: $60–$150 per furnace; often combined with duct cleaning and includes inspection of wiring, burners, and valves
Air Conditioning Repairs: $220–$1,600 for leak repairs, up to $5,600 for air handler replacement; duct condensation and mold can result from imbalances or faulty parts
Air Conditioner Maintenance: $75–$200 for a basic AC tune-up; filter changes and thermostat installation are DIY-friendly alternatives
Dryer Vent Cleaning: $100 when bundled with duct cleaning, or $100–$170 as a standalone dryer vent cleaning service
Air Duct Coating: $180–$630; applies a protective layer inside ductwork to reduce dust and debris circulation
Air Duct Repairs: $200–$800; addressing issues early costs less than deferring air duct repairs, which reduce airflow efficiency and raise energy costs
Only the pros have the proper skills and experience to complete an air duct cleaning. If you've discovered mildew growing in your ducts, it's time to contact a local air duct cleaning expert.
The pros are able to provide a deep cleaning of home air ducts that homeowners can't achieve by themselves. Here's why:
Professionals use air compressors, blowers, specialized sealing vacuums, agitators, and unique brushes to thoroughly clean air ducts.
Expert cleaners use the right tools for different types of air ducts, ensuring that more delicate ductwork isn't damaged.
The pros can spot cracks, nests left by pests, and other problems while they work, letting you know what needs extra attention.
A cleaning service can apply fungicide coatings, filters, and other add-ons to address specific duct problems.
Here are DIY steps to take for a minor cleaning or prep ahead of a pro:
Inspect your crawlspaces, including in the vents. If you can see the light, you've likely found a crack or gap. Alert your pro so they can help you plan for repairs.
Check your fan system for a primary filter and make sure the filter is replaced.
If the vent covers are dirty, clean them thoroughly ahead of a professional cleaning.
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
Get multiple quotes
Set a firm budget for the air duct cleaning project based on quotes from multiple pros in your area.
Consult your air duct pro about which add-ons are necessary for your home.
Ask the pro to estimate how long the cleaning will take so you can schedule accordingly.
Clear the space around the vents to make them easily accessible to air duct pros.
