Flexible duct price list information shows what buyers pay for materials and installation of HVAC flexible duct runs in homes. Typical pricing ranges depend on diameter, length, insulation, and labor; expect $2-$12 per linear foot for materials and $75-$150 per hour for installers in the U.S.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Uninsulated flex duct (per linear ft) | $2 | $4 | $6 | Assumptions: 6″–10″ diameters, bulk roll pricing. |
| Insulated flex duct (per linear ft) | $4 | $7 | $12 | Assumptions: R4–R6 insulation, typical residential lengths. |
| Factory-made flex duct boots or transitions (each) | $8 | $20 | $45 | Assumptions: standard fittings, galvanized collars. |
| Install labor (per hour) | $75 | $100 | $150 | Assumptions: licensed HVAC tech, no ductboard work. |
| Complete 100 ft run installed | $300 | $800 | $1,800 | Assumptions: mix of diameters, R6 insulated, moderate access. |

How Much Flexible Duct Materials And Typical Total Price
Most homeowners pay $300-$1,200 for a small system branch (20–100 linear ft) and $1,200-$3,500 for full-home flexible duct replacement (200–800 linear ft). Typical total price depends on total linear footage, average diameter, and whether insulation is factory-applied.
Assumptions: Midwest labor rates, standard materials, normal access.
Breakdown Of Costs: Materials, Labor, Equipment, And Disposal
| Cost Component | Materials | Labor | Equipment | Delivery/Disposal |
|---|---|---|---|---|
| Small branch (30 ft) | $60-$210 | $75-$300 | $0-$40 | $0-$25 |
| Medium job (100 ft) | $400-$900 | $300-$900 | $0-$100 | $20-$75 |
| Full replacement (400 ft) | $1,600-$4,800 | $1,200-$4,800 | $50-$200 | $50-$200 |
Materials typically account for 30–55% of a small job and 40–60% of a large replacement due to longer duct runs and more fittings.
Which Variables Change A Flexible Duct Quote Most
Diameter, linear footage, insulation type, and access constraints are primary drivers. Increasing average diameter from 6″ to 12″ can raise material cost by roughly 40%-80% per linear foot.

Two niche-specific drivers: large-diameter runs over 12″ often need thicker spiral wire and heavier insulation (+$2-$6/ft). Long single runs over 50 linear ft may require support straps and extra sealant (+$0.50-$1.50/ft).
Labor, Crew Size, And Typical Installation Timeframes
Install time varies with crew size and job complexity: a single tech can install 20–40 ft per hour for simple branches; a two-person crew averages 50–100 ft per hour on open attic runs. Expect 2–12 labor hours for single-room jobs, 12–60 hours for whole-house replacements.
Hourly rates: $75-$150 per hour depending on region and licensure. Assumptions: standard attic/ceiling access, no major framing.
How To Cut Flexible Duct Costs Without Sacrificing Performance
Buy straight runs in bulk, choose factory-insulated R4 instead of R6 where code permits, and repair rather than replace short sections when possible. Doing prep work—clearing attic access and removing old short sections—can reduce contractor labor time and lower the final quote.
Other tactics: schedule work off-season (fall/spring) and get 3 written quotes specifying linear footage, diameters, and insulation R-value.
Regional Price Differences And Where Costs Are Higher
Prices are typically 10%-30% higher in coastal urban markets. Example deltas: Northeast +15%-30%, West Coast +20%-35%, Midwest -5%-10% compared to national average. Remote or rural jobs may add travel fees or minimum charges of $100-$350.

Assumptions: urban market labor premiums, same material specs.
Common Add-Ons, Removal Fees, And Real-World Quote Examples
| Item | Typical Price | Notes |
|---|---|---|
| Old duct removal (per job) | $50-$400 | Depends on access and disposal rules. |
| Boots, collars, and registers (each) | $8-$45 | Includes metal collars and flexible adapter boots. |
| Air-sealing and mastic (per hour) | $75-$150 | Often charged as part of labor. |
Quote examples: Example A: 40 ft insulated flex (R6), one tech 3 hrs = $250-$420 total. Example B: 200 ft mixed diameters, two techs 16 hrs = $1,600-$3,600 total. Example C: Full 500 ft replacement, materials $2,500-$6,000 plus labor $3,000-$7,500 = $5,500-$13,500 total.
