• \( 6.5 \) — Average cost per square foot (USD)

Explanation: This formula provides a baseline estimate, though actual costs may vary based on system type, local labor rates, and other factors.

3. Importance of HVAC Cost Estimation

Details: Accurate cost estimation helps homeowners budget for HVAC replacement and compare quotes from contractors.

4. Using the Calculator

Tips: Enter the total square footage of your home or the area being serviced by the HVAC system. The value must be greater than 0.
