What Homeowners Pay For Typical Duct Replacement
Most single-family replacement jobs cost $1,200-$6,000 for partial work and $3,500-$12,500 for a full new system depending on square footage and access. Average quotes assume a 1,500-2,000 sq ft house, 8–10 registers, and moderate attic access.
Assumptions: Midwest labor rates, standard materials, normal access.
Breakdown Of Major Quote Items In A Duct Job
Understanding how a contractor divides the quote helps compare bids and spot padding. Labor and materials typically make up 75%-90% of the final price.
| Materials | Labor | Equipment | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $400-$3,500 (sheet metal, flex, insulation) | $600-$4,500 ($75-$125 per hour) | $100-$800 (crane, lift rental) | $50-$400 | $200-$1,000 |
How Size, Access, And Material Grade Change The Final Quote
Key variables change price dramatically: square footage, linear footage of runs, and duct material grade. Expect +20%-50% for multi-story homes or limited access that requires cutting ceilings.
Specific thresholds: sheet metal vs flex—sheet metal costs about $8-$20 per linear ft; flexible duct costs $4-$12 per linear ft. Jobs over 3,000 sq ft add complexity and often require larger trunks and more labor hours.

Ways To Reduce Ductwork Price Without Sacrificing Function
Scope control and timing cut costs: combine ductwork with HVAC replacement, choose sealed flex in accessible areas, and do prep work to improve access. Removing old insulation or clearing attic access before the crew can shave several hundred dollars off labor time.
Additional strategies: get three bids, accept off-peak scheduling, and avoid unnecessary upsized registers or decorative grilles until after airflow testing.
How Regional Labor And Climate Affect Duct Pricing
Prices vary by region: urban Northeast and West Coast are typically 10%-25% higher than Midwest average; rural areas may be 5%-15% lower but include travel fees. Expect regional premiums for seismic or high-code areas requiring additional bracing or materials.
| Region | Typical Delta vs Midwest | Example Impact on $6,500 Job |
|---|---|---|
| Northeast / West Coast | +10% to +25% | $7,150-$8,125 |
| South / Sunbelt | -5% to +5% | $6,175-$6,825 |
| Rural / Outlying | -5% to -15% (+ travel) | $5,525-$6,175 (+ travel fees) |
Common Add-Ons, Fees, And Hidden Expenses That Raise The Quote
Add-ons to watch for include air balancing, R-value upgrades, motorized dampers, and code-required fire dampers. Air balancing and testing typically adds $200-$800; fire/shaft penetrations can add $150-$600 per location.
Other fees: rush scheduling ($150-$500), minimum dispatch charges ($100-$250), and permit or inspection fees ($50-$500 depending on jurisdiction).
DIY Limits, Repair Versus Replace, And When To Hire A Pro
Small fixes like replacing a short flex run or sealing visible joints can be DIY at $50-$300 in materials, but full layout, sealing, and sizing require a pro. Improperly sized or poorly sealed DIY ducts typically reduce system efficiency and can cost 10%-30% more in energy bills long term.

Typical professional crew time: 6-24 hours for partial replacement, 1-4 days for full system installs depending on scope and crew size.
