Metal Ductwork Cost: Typical Prices, Ranges, and What Affects Estimates 2026

Metal ductwork cost varies widely by material, size, and complexity; homeowners typically pay between $1,000 and $8,000 for common projects. This article lists low-average-high pricing for sheet-metal HVAC ducts, plus per-foot and per-branch figures, and explains the main drivers contractors use to create a ductwork price.

Average Total Price For Replacing Metal Ductwork In A Typical Home

Full replacement in a 1,000–2,000 sq ft house typically costs $2,000-$7,500 depending on layout and material choice. Expect $7/ft on average for straight galvanized runs in an average-access attic or basement.

Assumptions: 1,200 sq ft home, 200-400 linear feet of ducting, standard 8-10 registers, regional labor within U.S. average.

Breakdown Of Major Cost Components In A Ductwork Quote

Understanding quote line items helps compare bids and spot markups. Labor and materials usually make up 80%-90% of the final invoice.

How Material Type Affects Price: Galvanized, Aluminum, Spiral, Or Stainless

Galvanized sheet is cheapest, spiral and stainless cost more. Expect galvanized at $4-$12/ft, spiral at $12-$40/ft, and stainless 2-3× galvanized pricing for corrosion-critical jobs.

Assumptions: per linear foot pricing for 6–18 inch diameter common mains and branches, excludes insulation and fittings.

Site Conditions And Size That Drive Big Price Differences

Access, number of bends, vertical runs, and total linear feet change cost substantially. Jobs with >300 linear feet or >12 major transitions usually jump total cost by 20%-50%.

Two niche thresholds: tight crawlspaces under 30 inches add $40-$100 per register in labor, and vertical risers over 20 feet often require lifts/crane adding $500-$2,000.

Practical Ways To Lower Metal Ductwork Price On A Replacement Job

Controlling scope, scheduling during low season, and reusing sound existing trunks reduce price. Replacing only damaged sections and reusing main trunks can cut costs by 30%-60% versus full replacement.

• Bundle work with HVAC contractor when replacing furnace to save on mobilization fees.
• Choose galvanized instead of spiral for hidden runs to save material cost.
• Prepare access areas before crew arrives to reduce hourly labor time.

Typical Labor Time, Crew Size, And Hourly Rates For Duct Projects

Smaller jobs often use 1-2 technicians; full replacements use a 3-4 person crew. Average labor rates run $75-$125 per hour; expect 10-40 labor-hours for most residential jobs.

Common Add-Ons, Removal Fees, And When Permits Raise The Price

Removal, insulation, balancing, and permits commonly add $150-$1,200. Permit and inspection fees typically range $50-$400 and can be required for full replacements in many municipalities.
