Cost to Run Ductwork: Typical Prices and Ranges 2026

Most U.S. homeowners pay between $700 and $6,500 to run new ductwork depending on scope. The Cost to Run Ductwork varies by linear feet, duct type, labor access, and finish work; small branch runs for a single room differ dramatically from a full 1,200 sq ft home install.

Item Low Average High Notes
Single-room branch run (flex to register) $150 $350 $700 10–30 linear ft, existing trunk
Partial system (3–5 rooms) $900 $2,500 $4,500 50–150 linear ft, attic or crawlwork
Full replacement or new system (1,000–2,000 sq ft) $2,500 $5,200 $12,000 Galvanized or insulated sheet metal

Typical Total Price For Running New Ductwork In A Home

A typical total price for running ductwork in a detached single-family home is $2,500-$6,000 for a complete system with 10–15 registers.

Assumptions: 1,000–1,800 sq ft home, mixed attic and crawl routing, mid-grade insulated flex + some sheet metal. Per-unit: $4-$9 per sq ft for full system or $6-$15 per linear ft for trunk lines. Assumptions: Midwest labor rates, standard materials, normal access.

Smaller jobs (one or two rooms) often cost $150-$700; major retrofits, high-efficiency sealed sheet-metal runs, or multi-story balancing add to $7,000-$12,000.

Breakdown Of Common Quote Line Items And Who Charges What

Material, labor, equipment, permits, and disposal usually make up the bulk of any ductwork quote.

Materials Labor Equipment Permits Delivery/Disposal
$2-$8 per linear ft (flex), $8-$20 per linear ft (sheet metal) $75-$125 per hour; total 8–40 hours $50-$250 (lift rental or compressors) $50-$400 depending on municipality $50-$300 for haul-away and disposal

Typical labor hours: simple branch run 1–4 hours; full install 20–40 hours depending on crew size and access.

How Linear Feet, Number Of Registers, And Access Affect Final Price

Linear feet and count of supply/return registers are the strongest price drivers: expect price jumps at 50 ft, 150 ft, and 300 ft thresholds.

Examples of thresholds: under 50 linear ft typically stays under $1,000; 50–150 ft commonly reaches $1,000-$3,500; above 300 ft often triggers $4,000+ and specialized equipment. Adding each register usually costs $60-$200 installed.

Site Conditions That Drive Higher Quotes: Attic, Crawl, And Multi-Story Work

Hard-to-access attics or multi-story drops increase labor by 25%-75% versus easy accessible basements or open crawlspaces.

Attic work: add $300-$1,200 for insulation clearance, platforming, and safety. Crawlspace with low clearance: add $200-$900 for time and kneepads. Multi-story vertical runs or chases can add $500-$2,000 for structural openings or fire-stopping.

Practical Ways To Reduce The Cost When Running Ductwork

Controlling scope, choosing insulated flex for branches, and doing preparatory work can cut price by 10%-40%.

  • Limit new trunk length and reuse existing trunk where possible.
  • Choose insulated flex for branch lines ($2-$8/ft) instead of custom sheet metal ($8-$20/ft).
  • Prepare access areas (clear attic space, move stored items) so crew spends less time on-site.
  • Schedule work in shoulder seasons to avoid peak contractor demand.

Regional Price Differences And What To Expect In Major U.S. Markets

Expect 10%-40% regional variation: higher in coastal metro areas and lower in rural interior states.

Region Typical Full-System Range Percent Above National Avg
Northeast (Boston/NYC suburbs) $3,500-$8,500 +20% to +40%
Midwest $2,200-$5,000 -5% to +5%
South (Atlanta/Dallas) $2,000-$5,500 -10% to +10%
West Coast (SF/LA) $4,000-$9,500 +30% to +50%

Add-Ons, Removals, And Typical Labor Time To Budget For

Allow for extra charges like old-duct removal, register replacement, balancing, and diagnostic testing; these add $100-$1,500 depending on scope.

Typical crew times: single-room run 1–4 hours; partial system 8–24 hours; full system 24–60 hours. Rush jobs or weekend work may carry 10%-50% premium. Common add-ons: sealing and mastic ($150-$600), new registers $20-$75 each, duct insulation $1.50-$4 per ft.
