Flexible duct price lists vary by diameter, length, insulation, and installation complexity; residential buyers typically pay between $2 and $12 per linear foot installed. This article gives a focused flexible duct price list and explains the main cost drivers to help plan a budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Uninsulated flex duct (per linear ft) | $2 | $4-$6 | $8 | 26–30 gauge, 6″–12″ diameters |
| Insulated flex duct (per linear ft) | $4 | $6-$9 | $12 | R4–R6 jacketed; 6″–12″ diameters |
| Installed single run (6″–8″, 10 ft) | $30 | $60-$90 | $120 | Includes labor and basic fittings |
| Complete system (single-family home) | $400 | $900-$1,800 | $3,500 | Depends on rooms, length, and installer |
What Buyers Usually Pay For Flexible Duct Runs
Typical total price for a single flex duct run is $30-$120 depending on length and whether insulation and connectors are included; an average entire-home flexible-duct replacement ranges $900-$1,800. Per-linear-foot pricing is the most useful measure for budgeting flex duct: $2-$12 per linear ft installed. Assumptions: Midwest labor rates, standard 6″–12″ diameters, normal attic or crawlspace access.
Breakdown Of A Flexible Duct Quote: Materials, Labor, Equipment, Delivery
This table shows typical shares and dollar ranges found on a contractor quote for flex duct work. Understanding each line helps compare estimates and spot padding or missing items.
| Materials | Labor | Equipment | Delivery/Disposal | Overhead |
|---|---|---|---|---|
| $2-$6/ft (uninsulated), $4-$12/ft (insulated) | $75-$125/hr; 1-3 hrs per run | $0-$150 (lift, scaffold) | $0-$150 (bagging, haul-off) | 10%-25% of subtotal |
How Diameter, Length, And Insulation Change The Final Quote
Diameter and length drive material costs; blown-in insulation or higher R-values add price. Short thresholds that change pricing: runs over 25 linear ft often add $0.50-$2.00/ft extra; diameters above 12″ jump material cost by ~25%-50%. Examples: replacing 6″ flex vs 10″ flex can change material cost from $3/ft to $6-$9/ft; adding R6 jacket adds $1.50-$3.50/ft.
Site Conditions And Access That Increase Flexible Duct Pricing
Tight attic access, long ceiling runs, or multi-level routing increases labor and equipment time; contractors add travel or minimum charges. Numeric triggers: attic runs requiring ladder/rope work add 1-3 extra labor hours; attic length over 50 ft commonly requires a second crew member and raises labor 30%-60%.
Practical Ways To Reduce Flexible Duct Expenses On Installations
Buyers can save by ordering standard diameters, combining runs, and prepping access points before the crew arrives. Actions that reduce cost most: remove old ducting yourself, choose R4 jacket instead of R8, and schedule work in off-peak seasons to get lower labor rates.
Regional Price Differences: Urban, Suburban, And Rural Examples
Labor-plus-overhead varies by market; urban areas often run 10%-40% higher than rural markets. Typical deltas: coastal metro pricing +20%-35%, Sun Belt suburbs +10%-20%, rural Midwest -10% to -20% versus national average.
Common Add-Ons, Fittings, And Extra Charges To Expect
Estimate extra costs for fittings, boots, balancing, and permits when applicable. Budget items: takeoff fittings $5-$25 each, boots/registers $8-$30 each, balancing fee $75-$250, permit if required $50-$300.
Example Quotes For Real-World Flexible Duct Jobs
Three realistic quotes help compare scope and pricing. Each example lists length, labor hours, per-foot cost, and total so buyers can match local quotes to expected ranges.
| Scenario | Specs | Labor | Per-Ft | Total |
|---|---|---|---|---|
| Single 10-ft run, 8″ insulated | 10 ft, R6, 8″ dia | 1 hr @ $90 | $6/ft | $150 |
| Whole-house replace (10 runs) | 200 ft total, mixed 6″-10″ | 12 hrs crew | $4.50/ft avg | $1,100 |
| Attic upgrade, long runs | 300 ft, R6, tight access | 20 hrs crew | $6.50/ft avg | $2,100 |
How To Compare Quotes And Spot Missing Items
Ask for line-item pricing by linear foot, count of fittings, labor hours, and permit allowance to compare bids fairly. Good quotes show material unit prices, labor hours, and any contingencies instead of a single lump-sum figure.
