What Does Professional Duct Cleaning Cost?
Professional air duct cleaning typically costs $300 to $700 for a standard single-family home, averaging around $475. The price reflects home size, number of vents, and whether add-on services are included.
Whole-Home Duct Cleaning: $300 to $700
A whole-home duct cleaning for a single-family home with 10 to 15 supply and return vents costs $300 to $700. This range covers the full duct system: supply ducts, return air ducts, air handler or furnace plenum, and all registers. The variation within this range reflects home size (more vents costs more), access difficulty, and whether the HVAC equipment is included in the cleaning scope. (For more on this, see What Affects the Cost of Duct Cleaning?.) The EPA makes no blanket recommendation for routine duct cleaning, advising it mainly for visible mold, pest infestation, or heavy debris.
Per-Vent Pricing: $25 to $50 per Vent
Some companies price per vent rather than per home. At $25 to $50 per vent, a home with 15 vents costs $375 to $750 similar to whole-home pricing. Per-vent pricing creates clarity about exactly what is included. Confirm whether the per-vent rate includes return air registers and the main trunk lines, or only supply registers the scope difference can be significant.
Add-On Services: $100 to $550
Dryer vent cleaning is often offered as an add-on to duct cleaning at $100 to $250, and often about $100 when it is booked alongside the duct cleaning. Duct sanitizing (applying an EPA-registered antimicrobial agent to the duct interior) adds $200 to $550 per HVAC system. Duct sealing (sealing leaks in the duct system after cleaning) is priced separately at $600 to $1,200 for hand-sealing accessible joints, or $1,500 to $2,500 for the Aeroseal aerosol process. Confirm which services are included in the base price and which are add-ons when comparing quotes. (For more on this, see Hidden Costs of Duct Cleaning.) The U.S. Fire Administration found failure to clean was the leading ignition factor in home clothes dryer fires, at 31 percent.

Planning Your Project Budget
The cost ranges in this article are based on industry data and are intended as planning benchmarks, not fixed prices. The actual cost for your project depends on your specific home, your local labor market, the current price of materials, and the scope the contractor confirms after a site inspection.
Always get at least two written quotes on equivalent defined scope before committing to any home services project. Wide price variation between quotes usually reflects differences in material quality, scope completeness (what is included and what is not), or contractor overhead and experience level rather than simple price competition.
Use the cost data in this article to ask better questions during the quoting process: What material is included? What does that per-square-foot or per-linear-foot rate include and exclude? Are permits, cleanup, and disposal included? What is the warranty on labor? These questions turn a quote into a comparable basis for decision-making. (For more on this, see Questions to Ask Before Hiring a Duct Cleaner.)
Working With a Contractor on This Project
Getting the right outcome on any home services project starts before the work begins. A few consistent practices make the difference between a smooth project and a frustrating one.
Get at least two or three quotes. A single quote gives you no basis for comparison. Two or three quotes reveal the market rate for the work, expose scope differences between bidders, and let you assess contractor communication quality before any commitment is made. The lowest bid is not automatically the best value if the scope is thin or the materials are underspecified.
Ask for licenses and insurance before work starts. Verify current general liability insurance and, for any work involving workers on your property, workers compensation coverage. Licensing requirements vary by state and trade; confirm the specific requirements in your jurisdiction. A licensed contractor who carries appropriate insurance protects both parties if something goes wrong during the project.
Get the scope in writing. A written proposal that specifies materials, labor scope, timeline, what is included (permits, cleanup, disposal), and warranty terms is the foundation of a professional engagement. Verbal agreements on any of these points invite misunderstanding. For any project over $500, written scope is non-negotiable.
Clarify the payment schedule upfront. A reasonable payment schedule ties major payments to project milestones: a deposit at signing, a payment at material delivery or project start, and a final payment at completion after a walkthrough confirms satisfaction. A contractor who requires full payment upfront before work begins is a red flag in any trade.
