1. What is HVAC Replacement Cost?

The HVAC replacement cost calculator estimates the approximate cost to replace a heating, ventilation, and air conditioning system based on the square footage of the space. The calculation uses a standard industry multiplier of $6.50 per square foot.

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
• \( 6.5 \) — 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 components needed.

3. Importance of HVAC Cost Estimation

Details: Accurate cost estimation helps in budgeting for HVAC system replacement, comparing contractor quotes, and financial planning for home or business maintenance.

4. Using the Calculator

Tips: Enter the total square footage of the space to be conditioned. For multi-zone systems, use the combined area of all zones.

5. Frequently Asked Questions (FAQ)

Q1: Is the $6.50/sq ft accurate for all systems?
A: This is an average. High-efficiency systems or complex installations may cost more, while basic systems may cost less.

Q2: Does this include ductwork replacement?
A: No, this estimate is for the HVAC unit only. Ductwork replacement would be additional.

Q3: How often should HVAC systems be replaced?
A: Typically every 10-15 years, depending on maintenance and usage.

Q4: What factors affect the actual cost?
A: System type (central, mini-split, etc.), brand, SEER rating, local labor costs, and any needed modifications to existing infrastructure.

Q5: Should I get multiple quotes?
A: Yes, always get at least 3 quotes from licensed HVAC contractors for accurate pricing.
