Most U.S. homeowners pay between $300 and $800 to clean ductwork, with larger or contaminated systems costing more; the cost to clean ductwork depends on system size, contamination level, and access. Typical low-average-high pricing and the main drivers are summarized below.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house duct cleaning | $200 | $450 | $1,200 | Assumptions: 2,000 sq ft home, 8–12 vents, normal access. |
| Dryer vent cleaning | $65 | $120 | $250 | Per dryer, single-level access. |
| Mold remediation added | $400 | $1,200 | $4,000 | Depends on containment and HVAC component replacement. |
| Per-vent cleaning | $15 | $35 | $75 | Register/vent only, not full duct run. |
What Homeowners Usually Pay For Whole-House Duct Cleaning
Standard whole-house duct cleaning for a typical U.S. single-family home runs about $300-$800, with an average near $450. Most cleanings include HVAC register vacuuming, brush/agitation, and a negative-pressure vacuum system.
Assumptions: 1–3 story, 1.5–3 ton furnace/AC, 8–14 vents, normal attic/basement access.
Breaking Down the Quote: Materials, Labor, Equipment, Permits
Quotes separate into labor, equipment, and small material or disposal fees; permits are uncommon unless mold remediation triggers them.
| Labor | Equipment | Materials | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $75-$125 per hour | $150-$450 flat (vacuum/extraction) | $10-$100 (filters, brushes) | $0-$150 (haul-away for debris) | $50-$500 (unexpected repairs) |
Labor typically dominates the invoice when technicians need 2–6 hours on site.
How Size, Number of Vents, and Duct Length Change the Price
Cost scales with square footage, vent count, and linear duct length: small homes (under 1,200 sq ft) usually cost $200-$400, medium homes (1,200–2,500 sq ft) $350-$700, and large homes $700-$1,200+. Expect an extra $25-$75 per additional vent beyond the baseline 8–12 vents.
Numeric thresholds: under 1,200 sq ft; 1,200–2,500 sq ft; over 2,500 sq ft. Also, >200 linear ft of ductwork often adds 10–25% to labor.
Site Conditions and Contaminants That Increase The Final Quote
Hard-to-access ducts, heavy dust/debris, rodent droppings, or visible mold raise prices substantially; containment and PPE requirements also add cost. Mold remediation or biohazard cleanup can add $400-$4,000 depending on containment and component replacement.
Numeric drivers: visible mold in >3 returns, rodent nests, or soot from a recent fire typically push a job into the high range.
Practical Ways To Reduce Your Duct Cleaning Expense
Control scope by cleaning only main runs and high-return registers, replace filters before service, and prepare access points to save time. Removing obstacles and replacing cheap filters yourself can shave 15–30% from the labor portion of a quote.
- Combine duct cleaning with HVAC tune-up to get bundled rates.
- Schedule during shoulder seasons to avoid peak technician demand.
- Limit add-ons: only authorize mold remediation after a documented inspection.
How Prices Vary Across U.S. Regions and Climate Zones
Regional labor and demand affect price: Northeast/West Coast typically run 10–25% above national average; Midwest and South often 5–15% below. A $450 average in the Midwest may be $500–$560 in urban West Coast markets for the same job.
| Region | Typical Range | Delta vs. National Avg |
|---|---|---|
| Northeast/Metro East | $350-$900 | +5% to +20% |
| Midwest | $250-$650 | -5% to -15% |
| West Coast/Urban | $400-$1,000 | +10% to +25% |
| South & Rural | $200-$700 | -10% to +5% |
Typical Add-Ons, Diagnostic Fees, and Real-World Quote Examples
Expect optional add-ons: dryer vent cleaning ($65-$250), coil cleaning ($120-$400), filter replacement ($20-$80), and camera inspection ($150-$350). Inspectors often charge a diagnostic fee that may be waived if work proceeds.
| Example Job | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Small home | 1,100 sq ft, 8 vents | 2 hrs | Per-vent $20 | $220-$320 |
| Medium home | 1,800 sq ft, 12 vents | 3–4 hrs | Vacuum fee $200 | $450-$650 |
| Large home w/ mold | 3,000 sq ft, 16 vents | 6–12 hrs | Mold work $1,200+ | $1,500-$4,500 |
Questions That Change The Quote When You Call A Contractor
Expect the technician to ask about home age, visible debris, HVAC component access, and previous mold issues; providing photos speeds accurate estimates. Clear answers about attic/basement access and existing filter size will reduce surprise fees during the job.
