Ductwork Cost Calculator


Ductwork plays a crucial role in the ventilation and air conditioning systems of buildings. It’s essential to have an estimate of the cost involved in installing ductwork before starting a project. The Ductwork Cost Calculator simplifies this process, helping you determine the total cost quickly and accurately.


To calculate the cost of ductwork installation, we use the following formula:

Total Cost = Length (ft) × Width (ft) × Height (ft) × Cost per Square Foot

How to Use

  1. Enter the length of the ductwork in feet.
  2. Enter the width of the ductwork in feet.
  3. Enter the height of the ductwork in feet.
  4. Select the material used for the ductwork from the dropdown menu.
  5. Click the “Calculate” button to see the estimated total cost.


Let’s say we have a ductwork project with the following specifications:

  • Length: 20 feet
  • Width: 10 feet
  • Height: 5 feet
  • Material: Galvanized Steel

Using the Ductwork Cost Calculator, the estimated total cost would be: $350.00


  1. What factors affect ductwork installation cost?
    • The size of the ductwork (length, width, height).
    • The material used (e.g., galvanized steel, aluminum).
    • Labor costs and installation complexity.
  2. Is this calculator accurate for all ductwork projects?
    • This calculator provides a rough estimate. Actual costs may vary based on specific project requirements.
  3. Can I change the material type for different sections of ductwork?
    • Yes, you can use different materials for different sections and calculate the cost separately.
  4. Do I need professional installation for ductwork?
    • It’s highly recommended to hire professionals for ductwork installation to ensure safety and efficiency.
  5. Are there any maintenance costs for ductwork?
    • Periodic maintenance may be required to keep ductwork in optimal condition.
  6. What are some common materials used for ductwork?
    • Common materials include galvanized steel, aluminum, stainless steel, and fiberglass.
  7. Can I reuse existing ductwork in a renovation project?
    • It depends on the condition of the existing ductwork. Consult with a professional for guidance.
  8. How can I reduce ductwork installation costs?
    • Seek competitive quotes from contractors.
    • Optimize the design to minimize material usage.
  9. Is ductwork insulation included in this cost estimate?
    • This calculator provides an estimate for ductwork only. Insulation costs may vary.
  10. Is ventilation ductwork different from air conditioning ductwork?
    • Yes, ventilation and air conditioning ductwork may have different specifications and cost factors.


The Ductwork Cost Calculator is a valuable tool for anyone planning ductwork installation. By providing quick estimates based on dimensions and material choices, it simplifies the budgeting process for your project. Remember that this calculator offers approximate costs, and actual expenses may vary depending on various factors. For precise cost estimates, consider consulting with ductwork professionals in your area.
