New duct work cost for a typical single-family home in the U.S. ranges from $1,200 to $12,000 depending on system size, material, and access. This article breaks down typical total pricing, per-unit rates, major line items, key variables like square footage and run length, and practical ways to lower the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New Duct Work (whole-house) | $1,200 | $4,500 | $12,000 | Assumptions: 1,200–2,500 sq ft, mixed flex and metal, normal attic/crawl access. |
| Per Linear Foot | $4 per LF | $7 per LF | $15 per LF | Includes fittings and basic insulation. |
| New Trunk Line (sheet metal) | $300 | $1,200 | $3,500 | Per trunk run, size dependent. |
| Supply/Return Boots & Registers | $25 | $75 | $250 | Per fixture, basic to premium. |

What Homeowners Pay For New Duct Systems
Typical whole-house new duct work pricing: low $1,200, average $4,500, high $12,000 for full replacement with a mix of flex and metal ducts. Smaller jobs for single rooms often fall in the $300-$1,200 range; full systems for 2,000+ sq ft homes hit the upper ranges.
Assumptions: Midwest labor rates, standard materials, normal access.
Materials, Labor, Equipment, and Disposal Line Items
| Materials | Labor | Equipment | Disposal | Taxes/Permit |
|---|---|---|---|---|
| $300-$4,000 (flex, sheet metal, fittings) | $400-$6,000 ( typical) | $50-$600 (lifts, scaffolding) | $50-$400 | $0-$400 (local permit) |
Materials and labor typically split 40%-60% of the total; complex access can push equipment and disposal above these ranges.
How Linear Feet, Duct Diameter, and Insulation Affect Price
Per-linear-foot pricing: $4-$9 per LF for insulated flex, $8-$15 per LF for rigid sheet metal. When the total run exceeds 200 linear feet, expect per-foot labor efficiencies and a 10%-20% reduction in per-foot price; short runs under 50 LF can cost 20%-30% more per foot.
Diameter matters: small supply runs (4–6″) cost less; mains (10–18″) escalate material and handling costs.

Site Conditions That Change the Quote Dramatically
Key site variables: attic vs. crawlspace access, ceiling height, and length of runs. Examples: Attic access adds $0.50-$2 per LF for insulation and safety gear; tight interior chases can add $50-$200 per boot for cutting and finishing.
Electrical or HVAC system relocation, structural cuts, or fire-stopping upgrades can add $500-$3,000 to a project.
Ways To Reduce New Duct Work Price Without Sacrificing Function
Control scope by sealing and repairing existing trunk lines instead of full replacement, choose insulated flex for non-visible runs, and schedule work during off-peak seasons. Getting three competitive quotes and asking for line-item pricing (materials, labor, equipment) typically saves 8%-15%.
Performing basic prep—clearing attic access, removing stored items, and providing working electricity—reduces labor hours and possible hourly-rate adders.
Regional Price Differences: Urban, Suburban, and Rural Examples
| Region | Typical Whole-House Range | Delta vs. National Average |
|---|---|---|
| Northern Cities | $2,000-$9,000 | +10% to +25% |
| Suburban Midwest | $1,200-$5,000 | -5% to -15% |
| Rural/Remote | $1,500-$7,500 | +0% to +30% (travel, logistics) |
Labor rate differences drive most regional variance—urban markets often charge $75-$125 per hour; rural crews may charge travel or minimum fees.
Representative Quotes: Three Real-World Examples
| Job | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Small Remodel | 3-room supply run, 60 LF flex, 6 boots | 6–8 hours | $7 per LF, $60 per boot | $700-$1,100 |
| Full Replacement | 1,800 sq ft home, 300 LF mixed, 18 boots | 24–40 hours | $8 per LF, $75 per boot | $4,000-$7,500 |
| High-End Sheet Metal | 2,500 sq ft, 350 LF sheet metal mains, insulated branches | 40–60 hours | $12 per LF, $120 per boot | $8,000-$13,000 |
These examples assume no major structural changes and normal permit requirements; adding a new air handler or zoning will raise totals significantly.

Common Add-Ons, Prep Work, and Permit Costs That Increase the Price
Typical add-ons: balancing dampers $40-$150 each, zoning dampers $150-$500 each, new plenums $250-$1,200, and registers $25-$250 each. Permits and inspections usually cost $0-$400 depending on local code and job size.
Demolition or removal of old ducts runs $150-$1,000, and mold or asbestos remediation greatly increases costs, often starting at $1,000 for minor abatement.
