Residential buyers typically pay $1,200-$8,000 to install new HVAC ductwork depending on home size, material, and complexity. How much does duct installation cost varies by system type, linear feet, and whether existing ducts are removed or sealed.

Average Total Price For New Duct Installation By Home Size
Typical total price rises with square footage and number of supply runs.
Small homes (under 1,200 sq ft): $800-$3,000 for basic flexible ductwork and registers. Medium homes (1,200–2,500 sq ft): $2,000-$6,000 for mixed flexible and sheet metal. Large homes (over 2,500 sq ft): $4,500-$12,000+ for full sheet metal systems or multi-zone designs. Assumptions: standard 8–10 registers, normal attic/crawl access, average labor market.
Typical Quote Breakdown: Materials, Labor, Equipment, Permits, Delivery/Disposal
Most estimates split into material, labor, equipment rental, permit fees, and disposal/transport.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $400-$3,000 (flex vs. sheet metal) | $600-$4,500 ( $75-$125 per hour) | $0-$400 (lift or insulation blower) | $0-$500 (local) | $75-$600 (old duct removal) |
How Square Footage, Duct Material, and Number Of Runs Change The Price
Linear footage and material grade are primary cost multipliers.
Flexible duct typically costs $4-$9 per sq ft installed or $3-$7 per linear ft; sheet metal installed runs $8-$20 per linear ft. Adding more than 10 supply runs increases labor by 15%-35%. Jobs over 2,500 sq ft commonly require larger trunk ducts and can add $1,000-$3,500 to the total.

Variable examples: switching from flex to 26-gauge sheet metal adds ~$6-$12 per linear ft; each additional zone control adds $300-$800.
Practical Ways To Lower Duct Installation Price Without Sacrificing Performance
Control scope and prep work to cut labor and material hours.
Keep existing duct routing where possible to avoid new framing or soffits. Choose high-quality flexible duct for short runs and sheet metal only for long trunks. Schedule work in shoulder seasons to avoid peak contractor demand. Provide clear attic access and remove insulation in targeted areas to reduce site prep charges.
How Regional Pricing Differs Across The U.S.
Expect 15%-40% variation between rural Midwest and high-cost urban coastal areas.
Typical deltas: Midwest baseline; Northeast/West Coast prices are roughly +20%-40%; Southern states often sit -10% to -20% below coastal averages. Permitting and prevailing wage areas can add $300-$1,200 to a job compared with non‑regulated counties. Assumptions: similar job scope and materials.
Common Add-Ons, Removals, and Site Fees That Increase Price
Removal of old ducts, insulation, and air sealing frequently adds material and disposal charges.

Old duct removal: $200-$1,200 depending on accessibility. Insulation of ducts: $1.50-$3.50 per linear ft. Air-sealing and balancing add $300-$1,200. Rush scheduling or weekend work can add 10%-50% to labor line items.
