1. What is the HVAC Cost Formula?

The HVAC replacement cost formula estimates average installation costs based on the square footage of the area being serviced. The $6.5 per square foot multiplier comes from industry average cost charts.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Area \) — Square footage of the space (sq ft)
• \( 6.5 \) — Average cost per square foot (USD)

Explanation: This provides a rough estimate based on average installation costs across different regions and system types.

3. Importance of HVAC Cost Estimation

Details: Accurate cost estimation helps in budgeting for HVAC system replacements and comparing quotes from different contractors.

4. Using the Calculator

Tips: Enter the total square footage of the area to be cooled/heated. For multi-zone systems, use the combined area.
