Typical metal ductwork cost ranges widely depending on material, size, and labor. How Much Does Metal Ductwork Cost buyers pay: low totals start near $600, average projects run $2,000-$6,000, and high-end complex installs hit $10,000+. Major drivers are total duct linear feet, sheet metal gauge, number of registers, and access difficulty.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house supply/return ducts | $600 | $2,000-$6,000 | $10,000+ | Assumptions: 1,200-2,500 sq ft home, standard 26–28 gauge galvanized steel, normal attic access. |
| Branch runs (per linear ft) | $4 per lf | $6-$12 per lf | $15 per lf | Includes materials and labor for 4-6″ round to 12″x8″ rectangular. |
| Installation labor | $300 | $750-$2,500 | $5,000 |
Typical Total Price And Per-Unit Rates For Metal Ductwork
For a standard U.S. single-family home, expect the total metal ductwork price to fall in a clear low-average-high band based on scope and material. Average installs for a 1,800–2,200 sq ft home with new supply and return ducts typically cost $2,000-$6,000.
Per-unit examples: trunk/main duct 12″x10″ runs $10-$20 per linear ft; small branch runs 6″ round $4-$9 per linear ft; new boot/register installation $25-$75 per fixture. Assumptions: Midwest labor rates, standard galvanized sheet metal, one HVAC crew, attic/garage access.
Breakdown Of Materials, Labor, Equipment, And Disposal
| Materials | Labor | Equipment | Delivery/Disposal | Overhead |
|---|---|---|---|---|
| $200-$2,500 (sheet metal, boots, dampers) | $300-$3,500 (installation crew) | $50-$400 (lifts, flex tools) | $50-$400 (old duct removal) | $100-$800 (markup, travel) |
Materials typically represent 20%-40% of the quote while labor is the single largest line item.
How Size, Gauge, And Total Linear Foot Change The Final Quote
Linear footage and duct cross-section are primary variables: small projects under 100 lf often cost $600-$1,200; mid-size 300–800 lf projects usually land $2,000-$6,000; over 1,000 lf or multi-level systems can exceed $8,000. Upgrading from 28-gauge to 26-gauge galvanized sheet metal adds roughly $0.50-$1.50 per lf and improves rigidity.
Niche drivers: adding insulated duct board or double-wall ductwork typically adds $2-$6 per lf; long runs over 30 ft without intermediate access add labor premiums of 10%-25%.
How Labor Hours, Crew Size, And Job Duration Affect Pricing
A typical 1,800–2,200 sq ft duct replacement takes 10-30 hours with a 2-3 person crew. Expect labor rates of $75-$125 per hour per technician; small crews and longer durations push quotes higher.
Example: 3 technicians × 12 hours × $90/hr = $3,240 labor. Jobs with complex attic insulation removal, tight crawlspaces, or ceiling penetrations increase labor hours by 30%-100%.
Real-World Quote Examples With Specs And Totals
| Scenario | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Small condo duct repair | Replace 100 lf, 6″ round branches | 8 | $6 per lf | $600-$900 |
| Typical suburban home replacement | 600 lf, mixed 10″x8″ trunks + branches, new boots | 24 | $8-$12 per lf | $3,200-$6,800 |
| Large multi-level remodel | 1,200 lf, thicker gauge, insulation, demo | 60 | $10-$15 per lf | $10,000-$18,000 |
These examples show how linear footage, access, and material choices drive the total quote.
Common Add-Ons, Removal Fees, And Permit Considerations
Common extras: removing old ducts $150-$800, disposal fees $50-$300, new register/boot $25-$75 each, sound attenuators $150-$400 each. Permit and inspection fees vary by city from $50 to $500 and may be required for system rework.
Some areas require sealing to current code; duct sealing and pressure testing add $200-$700 to a typical job.
How Regional Differences And Seasonal Demand Change Prices
Prices differ by market: urban coastal regions are typically 10%-25% higher than Midwest averages; rural areas may be 5%-15% lower but include travel surcharges. Peak HVAC season (spring/fall) can raise quotes by 10%-20% due to contractor demand.
Assumptions: percentage deltas apply to combined materials + labor, not fixed permit costs.
Practical Ways To Reduce Metal Ductwork Price On Your Quote
Control scope by replacing only damaged runs, reuse existing trunks when feasible, choose 28-gauge over thicker gauge when acceptable, and schedule work off-peak. Providing clear attic/crawlspace access and removing loose insulation before crews arrive can cut labor hours and reduce the bid by 5%-15%.
Obtain 3 written quotes, ask contractors to itemize linear footage and labor hours, and compare identical material specs to reduce unexpected markups.
