Buyers typically pay between $1,200 and $15,000 for ductwork replacement and installation cost depending on scope, material, and access. Main cost drivers are home size, linear feet of duct, material type (sheet metal vs. flex), and labor rates in the local market.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full replacement (1,500–2,000 sq ft) | $3,000 | $7,500 | $15,000 | Assumptions: single-family, standard 8-ft ceilings, moderate attic access. |
| Partial replacement (one floor or attic) | $800 | $2,200 | $6,000 | Targeted rooms or old main trunk. |
| New installation (new construction) | $2,000 | $5,500 | $12,000 | Includes basic registers and rough-in. |
| Flexible duct per linear ft | $4/ft | $8/ft | $12/ft | Includes connectors and basic insulation. |
| Metal duct per linear ft | $10/ft | $18/ft | $30/ft | Includes sealing and hangers. |
Typical Total Price For Replacing Home Ductwork (1,500–2,000 sq ft)
Full-system replacement for an average 1,500–2,000 sq ft home typically runs $3,000-$15,000 with most homeowners paying about $7,500. Choose a mid-range estimate of $6,000-$9,000 for standard sheet-metal trunks with flex branch runs in a house with attic access.
Assumptions: Midwest labor rates, standard 10–15 trunk/branch runs, 100–250 linear feet of duct, moderate attic crawl space.
Material, Labor, Equipment, Permits Breakdown For Ductwork Quotes
Detailed quotes separate materials, labor, equipment, permits, and disposal; understanding each line helps compare bids. Expect labor and materials to be roughly 70–85% of the total quote.
| Component | Low | Average | High | Detail |
|---|---|---|---|---|
| Materials | $400 | $1,800 | $6,000 | Sheet metal, flex, seals, boots |
| Labor | $800 | $3,500 | $7,500 | (see labor block) |
| Equipment | $100 | $450 | $1,200 | Lift rental, specialty tools |
| Permits | $50 | $150 | $400 | Local mechanical permits |
| Delivery/Disposal | $75 | $250 | $800 | Old duct removal, landfill fees |
| Contingency | $200 | $600 | $2,000 | Access or hidden repairs |
How Duct Size, Trunk Runs, And Insulation R‑Value Change Price
Price scales with linear feet, diameter, and insulation. Expect costs to jump when total linear footage exceeds 100 ft, when trunk runs pass 50 ft, or when upgrading insulation from R-6 to R-8 or higher.
Examples: adding 50–100 linear ft of 10–12″ sheet metal adds $500-$2,200; each additional 50 ft of flex adds $200-$600; switching to insulated duct board or higher R-value can add $1–$4 per linear ft.
Numeric thresholds: >100 linear ft = +10–25%; trunks >50 ft = +$300–$900 for extra hangers/support; insulation upgrade R‑6→R‑8 = +$0.50–$3.50/ft.
Reduce Price By Choosing Sheet Metal Gauge, Flexible Duct, Or Limited Zone Upgrades
Control scope and material to cut costs without unsafe shortcuts. Switching select branch runs from custom sheet metal to insulated flex can save $3–$10 per linear foot while keeping main trunks metal for airflow.
Other savings: limit new registers to problem rooms, reuse existing boots when undamaged (saves $20–$60 each), schedule in shoulder season for lower labor rates, and get multiple itemized bids to compare tradeoffs.
Regional Price Differences Between Urban, Suburban, And Rural Markets
Geography affects labor and permit costs. Urban markets commonly run 15–35% higher than national averages; rural rates can be 5–15% lower.

State notes: high-cost states (CA, NY, MA) add roughly 20–40% on labor and permits. Midwestern and Southern metros often match the national average. Assumptions: prices reflect typical contractor overhead differences by region.
Typical Labor Time, Crew Size, And Hourly Rates For Ductwork Jobs
Labor varies by complexity. Full replacement usually requires a 2–4 person crew for 2–5 days (40–160 total crew hours) at typical rates of $75–$125 per hour per tech.
Common scenarios: small repair 1 tech for 1–3 hours ($75–$375), partial replacement 2 techs for 8–24 hours ($1,200–$6,000 labor), full system 3 techs for 24–80 hours ($5,400–$30,000 labor depending on rate).
Three Real-World Quotes For Common Ductwork Jobs
Example 1 — Simple repair: Replace 2 branch runs (25 ft each) with insulated flex. Materials $120, labor 3 hours × $90 = $270, total $420. Small repairs often cost $200–$800.
Example 2 — Partial replacement: One floor, 60 linear ft sheet metal trunk + 6 branches. Materials $1,200, labor 24 hours × $90 = $2,160, equipment/disposal $250, total $3,610. Typical range $2,000–$6,000.
Example 3 — Full replacement: 1,800 sq ft home, 200 linear ft mixed trunks and branches. Materials $3,200, labor 80 hours × $95 = $7,600, permits/disposal $500, contingency $700, total $12,000. Comprehensive jobs commonly land between $8,000 and $15,000.
Common Add-Ons, Disposal Fees, And Permit Costs To Expect
Itemized extras can add significantly to the final invoice. Budget $50–$400 for permits, $100–$800 for disposal, and $500–$3,000 if asbestos or mold remediation is required.
- Permit fees: $50-$400 depending on municipality.
- Old duct removal/disposal: $100-$800 depending on volume and access.
- Insulation removal or asbestos testing: $300-$3,000 if suspected.
- Air balancing or HVAC re-test: $150-$600 additional.
