1. What is the HVAC Replacement Cost Formula?

The HVAC replacement cost formula estimates the approximate cost to replace a heating, ventilation, and air conditioning system based on the square footage of the space. This provides a quick budgetary estimate for planning purposes.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Cost \) — Estimated replacement cost in US dollars
• \( Area \) — Total square footage of the space
• 6.5 — Average cost per square foot in USD

Explanation: This formula provides a rough estimate based on national averages. 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 in budgeting for home improvements, comparing contractor quotes, and financial planning for property maintenance.

4. Using the Calculator

Tips: Enter the total square footage of the space needing HVAC replacement. For multi-zone systems, calculate each area separately.
