1. What is the HVAC Cost Formula?

The HVAC cost formula estimates the total cost of a heating, ventilation, and air conditioning system based on the size of the home. The standard calculation uses $6.50 per square foot as a baseline estimate.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Cost \) — Total estimated HVAC system cost in US dollars
• \( Area \) — Total home area in square feet
• \( 6.5 \) — Cost per square foot in USD

Explanation: This provides a baseline estimate. Actual costs may vary based on system type, local labor rates, and additional features.

3. Importance of HVAC Cost Estimation

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

4. Using the Calculator

Tips: Enter your home's total square footage. For multi-story homes, use the total of all floors. The calculator provides a baseline estimate - actual costs may vary by 20-30%.
