Redo ductwork cost for a typical single-family home ranges widely depending on scope, materials, and access; most U.S. homeowners pay between $2,000 and $12,000. This article breaks down total price ranges, per-foot rates, main cost components, major drivers, and practical ways to lower the final price for duct replacement or full system rework.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Partial duct replacement (rooms, runs) | $500 | $1,500 | $4,000 | Per run or a few vents; short runs, accessible attic |
| Full duct replacement (typical 1,500–2,500 sq ft) | $2,000 | $6,500 | $12,000 | Includes supply/return trunking, boots, basic insulation |
| High-efficiency sheet metal, sealed | $4,000 | $8,500 | $15,000 | Better materials, extensive sealing, difficult access |
| Per linear foot | $4 | $8 | $20 | Depends on material, diameter, and insulation |
Typical Total Price and Per-Foot Rates for Replacing Ductwork
Most homeowners replacing most house ductwork should budget about $2,000-$12,000 depending on system complexity.
Typical totals: partial repairs start near $500; full replacement of ducts in a 1,500–2,500 sq ft home averages $6,500. Per-foot pricing is commonly $4-$20 per linear ft: $4-$9 per ft for flexible insulated ducts, $8-$15 per ft for insulated sheet metal, and up to $18-$20 per ft for large custom round sheet metal runs. Assumptions: suburban U.S., average attic access, standard 8–10 vents.
Material, Labor, Equipment, and Disposal Line-Item Pricing
Breaking a quote into parts reveals where savings are possible and which line items vary most by region and job difficulty.
| Materials | Labor | Equipment | Delivery/Disposal | Overhead |
|---|---|---|---|---|
| $400-$6,000 (duct, boots, registers) | $75-$125 per hour, total $400-$5,500 | $50-$400 (lift, tools) | $50-$600 (old duct disposal) | $200-$1,200 (markup, permits) |
Assumptions: 1–3 technicians, 6–40 labor hours depending on scope.
How Access, Home Size, and Duct Material Drive Final Price
Access and home size are primary drivers: easy attic access and 1,200–1,800 sq ft lowers labor to 10–20 hours; multi-story homes with chase work can require 30–60 hours.
Numeric thresholds: small job—under 200 linear ft typically under $2,000; medium job—200–600 linear ft $2,000-$8,000; large job—over 600 linear ft often $8,000+. Material grade thresholds: flexible insulated runs cost ~$4-$9 per ft; rigid sheet metal costs ~$8-$20 per ft depending on gauge and fittings.
Practical Ways to Reduce the Price of Replacing Ductwork
Controlling scope and timing cuts costs: repair or re-balance runs instead of full replacement when possible, and schedule off-peak seasons for lower labor rates.
Specific tactics: replace only failing sections, choose insulated flex ducts for accessible runs, remove minimal drywall by using attic or crawlspace access, get multiple detailed quotes, and bundle with HVAC replacement to reduce mobilization fees. Prepping access and clearing attic space reduces onsite labor.
Regional Price Differences and What To Expect Locally
Prices vary 10%-40% by region—expect higher rates in urban West Coast and Northeast metro areas and lower rates in the Midwest and parts of the South.
| Region | Typical Delta | Representative Full Replacement Range |
|---|---|---|
| Midwest | -10% to -20% | $2,000-$8,000 |
| South | -5% to 0% | $2,500-$9,000 |
| Northeast | +10% to +30% | $3,500-$12,500 |
| West Coast | +15% to +40% | $4,000-$14,000 |
Common Add-Ons, Permits, and Time Estimates That Affect Price
Expect additional costs for permit-required structural openings, insulation upgrades, and duct sealing or balancing tests.
Typical add-ons: permit fees $50-$500, duct sealing/pressure test $150-$600, additional insulation $300-$1,200, boot/register replacement $20-$75 each. Labor time: simple repairs 2–8 hours, partial runs 6–20 hours, full replacement 20–60 hours with 2–3 technicians. Assumptions: local code permitting and normal access.
Three Real-World Quote Examples With Specs and Pricing
Concrete examples help translate ranges into budgets for common scenarios.
| Scenario | Specs | Labor Hrs | Per-Unit Rates | Total |
|---|---|---|---|---|
| Small repair | Replace 2 runs, attic access | 4–6 hrs | $6 per ft flex | $500-$1,200 |
| Medium replacement | 300 linear ft, mix flex & sheet | 18–30 hrs | $8-$12 per ft | $3,000-$7,500 |
| Full high-quality replace | 700 linear ft, sealed sheet metal | 40–60 hrs | $12-$18 per ft | $9,000-$15,000 |
Assumptions: quoted work includes removal of old ducts and standard balancing; does not include HVAC equipment change unless noted.
