Most U.S. homeowners pay $300-$8,000 for AC duct work depending on repair, partial replacement, or full new installation; major drivers are duct length, material, and accessibility. This article lists typical AC duct work cost ranges, per-unit rates, and the variables that cause wide pricing differences.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Minor Repair (leaks, sealing) | $75 | $200-$450 | $800 | Per visit; depends on leak count and access |
| Register/Boot Replacement | $50 | $75-$175 | $300 | Per fixture including basic labor |
| Partial Reroute/Relocation | $300 | $700-$1,800 | $3,500 | Small runs moved or rebalanced |
| Full Duct Replacement (typical 1,200-2,000 sq ft) | $2,000 | $4,500-$6,500 | $12,000 | Includes materials and labor; varies by layout |
| New Duct System Per Linear Foot | $8/ft | $12-$20/ft | $30/ft | Trunk and branch installed in conditioned crawlspace or attic |

How Much AC Duct Work Costs For Typical Single-Family Homes
Expect a typical full duct replacement for a 1,500 sq ft home to cost $4,500-$6,500 in many markets. Partial repairs or sealing jobs can be as low as $75-$800 while complex full replacements in two-story homes often exceed $8,000. Assumptions: standard 8-10 supply registers, typical attic or crawlspace access, mid-grade sheet metal and flex ducts.
Material, Labor, Equipment and Disposal Line Items in a Quote
Quotes usually split into materials, labor, equipment rental, and disposal—each can represent 15%-45% of the total.
| Line Item | Low | Average | High | Typical Role |
|---|---|---|---|---|
| Materials (sheet metal, flex, insulation) | $200 | $800-$2,200 | $5,000 | Main material cost for runs and fittings |
| Labor | $150 | $1,200-$2,800 | $6,000 | Skilled HVAC installers |
| Equipment (blower, lifts, saws) | $0 | $50-$300 | $800 | Rental or contractor overhead for site equipment |
| Delivery/Disposal | $50 | $150-$400 | $900 | Old duct removal and debris hauling |
| Permits/Inspections | $0 | $50-$250 | $600 | Required in some jurisdictions for major replacements |
How Size, Linear Feet and Duct Type Affect the Final Quote
Linear footage, duct type, and airflow capacity are the strongest cost drivers—adding 100 linear feet of new trunk/branch typically adds $1,000-$2,500. For example, sheet-metal trunks cost $12-$30 per linear foot versus insulated flex at $8-$18 per foot. Larger homes (over 2,000 sq ft) often require larger trunks and more registers, increasing material and labor proportionally.
Specific numeric thresholds: sealed and insulated runs under 50 linear feet are often a small job under $800, while projects over 300 linear feet commonly exceed $6,000. Upgrading to higher MERV-rated filters or larger airflow capacity can add $150-$600 in duct modifications.
Practical Ways To Lower AC Duct Work Price On a Project
Controlling scope and timing significantly reduces cost—prioritize sealing and targeted repairs over full replacement when possible. Strategies: perform sealing and insulation instead of full replacement, schedule work in off-season months for lower labor rates, bundle duct work with planned HVAC replacement for labor efficiencies, and prepare access points to reduce labor time.

Simple prep by the homeowner—clearing attic space, labeling vents, and ensuring safe access—can shave 1-3 crew hours and save $75-$375 on labor.
Regional Price Differences: Urban, Suburban, and Rural Comparisons
Expect 10%-30% regional variance: urban (higher), suburban (average), rural (lower labor, higher travel fees). Example deltas: Coastal metro markets often run 15%-30% above national averages, Midwest suburban rates tend to be 5%-15% below coastal prices, and rural jobs may have lower hourly rates but $50-$250 in travel minimums.
| Region Type | Typical Full Replacement | Percent Delta vs National Avg |
|---|---|---|
| Coastal Urban | $5,000-$9,000 | +15% to +30% |
| Suburban | $3,800-$6,000 | -5% to +5% |
| Rural | $3,000-$6,000 (plus travel) | -10% to +0% plus travel fees |
Typical Job Time, Crew Size, And Labor Rates For Duct Work
Most duct jobs take 4-24 hours depending on scope with crews of 1-3 technicians. Small repairs: 1-4 hours at $75-$125 per hour. Partial reroutes: 6-12 hours. Full replacement for a 1,200-2,000 sq ft home: 16-40 hours. Assumptions: two-person crew, standard attic access.
