1. What is HVAC Replacement Cost?

The cost to replace an entire HVAC system is typically calculated based on the square footage of the space being conditioned. This calculator provides a rough estimate using a standard multiplier of $7.5 per square foot.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Cost \) — Estimated cost in US dollars
• \( Area \) — Square footage of the space
• \( 7.5 \) — Cost per square foot in dollars

Explanation: This provides a baseline estimate. 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 HVAC replacement projects and comparing contractor quotes.

4. Using the Calculator

Tips: Enter the total square footage of your home or space that needs HVAC replacement. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Is $7.5/sq.ft accurate for all systems?
A: This is an average. High-efficiency systems or complex installations may cost more, while simpler systems may cost less.

Q2: What factors affect the actual cost?
A: System type (central AC, heat pump, etc.), brand, SEER rating, ductwork modifications, and local labor costs.

Q3: Does this include ductwork replacement?
A: This estimate assumes existing ductwork is adequate. Duct replacement would add to the cost.

Q4: How often should HVAC systems be replaced?
A: Typically every 10-15 years, depending on maintenance and usage.

Q5: Are there rebates available?
A: Many areas offer rebates for high-efficiency systems. Check with local utilities and government programs.
