Typical metal ductwork cost for a whole-house HVAC system ranges widely depending on material, layout, and labor. Buyers typically pay $1,200-$12,000 for new metal ductwork with most projects around $3,500-$6,500; key drivers are square footage, sheet-metal gauge, and number of runs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small Repair / Section Replace | $75 | $200 | $650 | Per short run or single trunk, basic patching |
| Single-Room Duct Add | $300 | $700 | $1,500 | Includes boot, short branch, register |
| Full-System Replace (1,200-2,000 sq ft) | $1,200 | $4,500 | $12,000 | Sheet metal (galvanized) main + branches |
| Commercial / Large Homes (3,000+ sq ft) | $6,000 | $9,500 | $20,000 | Multiple zones, thicker duct, complex layout |

Typical Total and Per-Unit Prices For Metal Ductwork Installations
Most single-family home duct systems cost between $1,200 and $12,000 depending on scope and material.
Average full replacement for a 1,200–2,000 sq ft home: $3,500-$6,500. Per linear foot for straight galvanized round or rectangular duct: $4-$12 per ft installed. Per register/register box and boot: $40-$150 each installed. Assumptions: Midwest labor rates, standard 2–3 bedroom layout, normal attic or crawlspace access.
Breakdown Of Quote Line Items: Materials, Labor, Equipment, and Disposal
A typical contractor quote separates materials, labor, equipment, and disposal—understanding each helps compare bids.
| Materials | Labor | Equipment | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $300-$3,500 (sheet metal, boots, registers) | $600-$4,500 ( 6–40 hours) | $50-$400 (scaffolding, power tools) | $50-$400 (haul, disposal) | $100-$1,200 (allowance for unknowns) |
How Duct Size, Length, And Material Grade Affect The Final Price
Size, total linear footage, and sheet-metal gauge are the strongest cost variables; prices jump above specific thresholds.
Examples of numeric thresholds: projects under 50 linear feet often fall under $1,000; 50–250 linear feet typically cost $1,200-$6,000; over 300 linear feet commonly exceed $7,000. Upgrading from 26-gauge to 22-gauge galvanized sheet adds roughly $0.50-$1.50 per linear foot installed. Switching to insulated double-wall or ductboard can add $2-$6 per sq ft equivalent.

Site Conditions That Can Raise Pricing Quickly
Access, ceiling height, and existing obstructions materially increase labor hours and therefore the total price.
Examples: attic access with tight crawlspace adds 20–50% to labor; long horizontal runs above finished ceilings may add $8-$20 per linear foot for ceiling repairs. If duct runs require firestopping, expect permit/inspection fees of $75-$350 and added labor for sealing and fire-rated materials.
Practical Ways To Reduce Metal Ductwork Price On A Remodel Or Replacement
Controlling scope and timing yields the most predictable savings.
- Keep existing trunk where functional and only replace branches: saves 30–60% versus full replacement.
- Choose standard 26–24 gauge galvanized instead of premium heavy-gauge unless code requires thicker metal.
- Schedule work in off-peak seasons (spring/fall) to avoid rush premiums; expect 5–15% lower labor rates.
- Provide clear access (remove stored items, clear attic) to cut 1–2 labor hours and $75-$250.
Regional Price Differences For Metal Ductwork Across The U.S.
Labor and markup vary by region: expect coastal metro areas to be 10–30% higher than Midwest averages.
Typical regional deltas: Midwest baseline. West Coast and Northeast: +15–30%. Sun Belt suburbs: +5–15%. Rural markets: -10–20% but with potential minimum service charges of $300-$600.

| Full Replace 1,600 sq ft | 200–300 linear ft, 10–12 registers | 20–40 hrs | $3,200-$7,800 |
Common Add-Ons, Permits, And Hidden Fees That Affect The Final Bill
Expect extras like sealing, balancing, permit fees, and unexpected corrective work to add to the initial estimate.
