HOW TO USE IT

How to use the Ductwork Installation Cost Calculator

  1. 1

    Enter the total linear feet of ductwork.

  2. 2

    Set the number of return and supply registers.

  3. 3

    Choose the material and insulation.

  4. 4

    Review the total cost and line-item breakdown.

THE MATH

Ductwork cost formula

Total = length × (material + labor) + insulation + registers + removal

Rigid sheet metal runs ~$7/ft, flexible ~$3.50/ft. Labor averages ~$4/ft and rises with access difficulty (x1.2 moderate, x1.5 difficult). A typical 150 ft install with 4 returns and 12 supplies is a common baseline.

PRACTICAL EXAMPLE

150 ft of insulated flexible duct, moderate access

Materials = $525. Labor = $720. Insulation = $225. Registers = 4 × $200 + 12 × $110 = $2,120. Total = $3,590.

FAQ

Frequently asked questions

How much does ductwork installation cost in 2026?

Use $7-$15/ft as a planning allowance and replace it with the measured runs, selected material, access and current quotes.

Rigid or flexible ducts?

Compare durability, pressure loss, access and cost for the designed system.

Should ducts be insulated?

It depends on location and system design; confirm thermal and condensation requirements for the project.
