Average Total Price For Common Ductwork Repairs
Assumptions: Midwest labor rates, single-family home, standard metal or flex ducts, normal attic/crawlspace access.
Most homeowners pay between $150 and $1,200 for typical duct repairs; complete system replacement averages $1,500-$3,500.
Examples of totals: sealing a handful of leaks and reconnecting boot collars: $150-$450. Replacing several damaged runs or long sections of collapsed flex duct: $600-$2,000. Full sheet-metal trunk repair or full replacement for a 1,800 sq ft house: $1,800-$4,500.
Breakdown Of Major Cost Components On A Quote
| Materials | Labor | Equipment | Delivery/Disposal | Contingency |
|---|---|---|---|---|
| $20-$600 (tape, mastic, new duct sections, boots) | $75-$250 per hour or $150-$1,200 total | $0-$200 (lifts, scaffolding rental) | $0-$150 (debris, old duct disposal) | 10%-20% of total |
Labor often dominates the bill for repairs requiring attic or crawl access—expect $75-$125 per hour in many areas, or a flat repair trip fee of $150-$350.

Assumptions: cost changes illustrated relative to a 1,500 sq ft baseline with 8-10 vents.

Duct material, run length, and home size are the top levers: sheet-metal runs cost 20%-50% more than flex per linear foot.
Numeric thresholds: replacing flex duct runs under 25 linear ft typically costs $200-$600 per run; replacing sheet-metal trunk sections over 20 linear ft often costs $600-$2,000 due to labor and sealing. Larger homes (2,500+ sq ft) add $800-$2,500 to full system replacement compared with a 1,200 sq ft home because of added trunking and registers.
Ways To Reduce Duct Repair Price Before Calling A Contractor
Controlling scope and doing prep work reduces price: locate poor-access areas, remove insulation in the work path, and identify problem vents before the visit.
Practical steps: seal visible leaks with foil HVAC tape or mastic on small jobs ($20-$60 in materials), bundle multiple repairs across systems to lower per-trip charges, avoid replacing entire trunks when sectional repair is possible, and schedule work in off-peak seasons for lower labor availability pressure.
Regional Price Differences And What To Expect In Your City
Assumptions: percentages relative to national average pricing.
Expect 10%-40% higher prices in high-cost urban markets (West Coast, Northeast metro areas) and 5%-20% lower in rural or lower-cost Midwest markets.

Examples: a basic leak sealing visit that costs $150 in a Midwestern suburb may cost $200-$260 in San Francisco or New York City. Travel and disposal fees can add $50-$200 in remote or congested urban jobs.
Typical Job Durations, Crew Size, And How Time Affects Price
Smaller repairs: 1 technician for 30 minutes–3 hours; larger replacements: 2–4 technicians for 6–20 hours—labor time scales directly with run length and access difficulty.
Labor formula example: A 6-hour job at $95/hour equals $570 labor. Many contractors quote flat prices for common tasks (e.g., $350 for 3 leaks) to avoid hourly uncertainty.
