1. What is the $5000 Replacement Rule?

The $5000 replacement rule is a guideline used in the HVAC industry to determine whether to repair an existing system or replace it. If the product of your system's age (in years) and the repair cost exceeds $5000, replacement is typically recommended.

2. How Does the Calculator Work?

The calculator uses the $5000 rule equation:

Where:

• \( Age \) — Age of HVAC system in years
• \( Repair Cost \) — Estimated repair cost in dollars

Explanation: This rule accounts for both the diminishing returns of repairing older systems and the increasing likelihood of future repairs.

3. Importance of HVAC Replacement Decisions

Details: Making the right repair/replace decision can save thousands of dollars in energy costs and prevent unexpected breakdowns. Newer systems are significantly more energy efficient.

4. Using the Calculator

Tips: Enter your HVAC system's age in years and the estimated repair cost in dollars. The calculator will determine whether repair or replacement is more cost-effective.
