Why ductwork replacement costs matter

Formula with an Example of Calculation
Formula:
Total Cost = (Length × Cost per Foot) + Additional Fees
Example:

- Length = 100 feet
- Cost per Foot = $15
- Additional fees = $200
Calculation:
Total Cost = (100 × 15) + 200 = 1500 + 200 = $1700
This example helps you understand how total replacement cost is derived.
