Typical sheet metal ductwork cost for U.S. homes ranges from $8-$25 per linear ft for basic rectangular runs, with total project prices usually between $600 and $6,500 depending on size and complexity. This article explains what buyers pay for sheet metal ductwork, per-unit pricing, and the main drivers that change the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small residential run (10–30 lf) | $80 | $400 | $1,000 | Assumes 6–8 in round or small rectangular, basic fittings |
| Whole-house replacement (100–300 lf) | $900 | $3,500 | $12,000 | Includes multiple branch ducts, booting, sealing |
| Commercial medium job (300–1,000 lf) | $3,000 | $9,000 | $30,000 | Galvanized DWV/spiral, higher labor and insulation |
| Per linear foot (basic rectangular) | $4/lf | $12/lf | $30/lf | Material + labor; varies by gauge and fittings |

Typical Total Price For Residential Sheet Metal Ductwork
Most homeowners pay $900-$4,000 for replacing or installing 100–300 linear feet of sheet metal ductwork in a single-story home.
Assumptions: mid-range galvanized material, 8–12 in trunks, several 6–8 in branch runs, average attic or crawlspace access, local labor rates. Per-unit: $8-$18 per linear ft for rectangular; $4-$12 per lf for spiral round in same jobs. Assumptions: Midwest labor rates, standard materials, normal access.
Price Breakdown By Materials, Labor, Equipment, and Fees
Quotes typically separate Materials, Labor, Equipment, Delivery/Disposal, and Permits so buyers can compare line items.
| Materials | Labor | Equipment | Delivery/Disposal | Permits |
|---|---|---|---|---|
| $2-$12 per lf (galvanized sheet, spiral, fittings) | $75-$125 per hour; total $300-$3,000 | $50-$400 (lift rental, scaffolding) | $50-$500 depending on volume | $0-$400 depending on locality |
How Gauge, Duct Type, and Linear Feet Drive Price
Gauge thickness, duct shape (rectangular vs spiral), and total linear feet are primary spec drivers with clear breakpoints.

Examples of thresholds: thinner 26–28 gauge sheet is cheaper; moving to 24–22 gauge adds 10–30% in material cost. Spiral round becomes cost-effective after about 30–50 lf; below that rectangular fittings and transitions can raise price per lf by $3-$10. Jobs over 300 lf often get volume discounts of 10–20% on materials but require larger crews and higher equipment rental.
Site Conditions That Add Direct Costs
Tight access, multiple floor penetrations, and long runs through finished space commonly add $400-$2,500 to a quote.
Numeric site drivers: more than 6 attic or crawlspace entries adds $15-$45 per entry for protective measures; more than 20 penetrations (boots/registers) commonly increase labor by 20% or $200-$800. Long horizontal runs over 50 lf may require additional hangers at $8-$15 each.
Ways To Reduce Sheet Metal Ductwork Price Without Sacrificing Function
Controlling scope, doing demolition prep, choosing spiral over rectangular when possible, and scheduling off-peak can lower cost significantly.
- Trim scope: repair select runs instead of full replacement — repairs often $150-$800 versus $900-$4,000 for full replacement.
- Prep work: remove insulation, clear attic access, and mark routes to save 1–4 hours of labor ($75-$500 saved).
- Material choice: use spiral round for long continuous runs ($4-$12/lf) instead of boxed rectangular ($8-$25/lf) when fittings allow.
- Bundle HVAC work: adding ductwork during an HVAC replacement can save 5–15% on combined labor.
Regional Price Differences Across the U.S.
Labor and permit costs cause regional deltas: expect 10–35% higher prices in coastal urban markets than in Midwest or rural areas.
Typical deltas: Northeast/West Coast +15–35% of national average; Southeast/Midwest -5–15% below national average. Permit fees: larger cities often charge $150-$400 for ductwork permits; many smaller jurisdictions are $0-$100.

Real-World Quote Examples With Specs and Totals
Concrete quotes help set realistic expectations for common scenarios.
| Job | Specs | Labor Hours | Per-Unit | Total |
|---|---|---|---|---|
| Small repair | 20 lf, 8 in round, 4 fittings | 2–4 hours | $8/lf | $160-$400 |
| Whole-house replacement | 200 lf mixed rectangular & branches | 24–48 hours | $12-$18/lf | $2,400-$3,600 |
| Light commercial | 600 lf spiral duct, insulation | 80–160 hours | $6-$14/lf | $3,600-$8,400 |
Common Add-Ons, Removal Fees, and Permit Considerations
Expect separate line items for insulation, register boots, removal, and testing that can add $200-$2,000 to the job.
Typical add-ons: insulation $1.50-$6 per sq ft of duct surface; new boots/registers $10-$40 each; duct cleaning/testing $150-$600. Disposal or hazardous-material handling can add $100-$700 depending on volume and local rates.
