1. What is the $5000 HVAC Replacement Rule?

The $5000 rule is a simple guideline to help homeowners decide whether to repair or replace their HVAC system. If the product of your system's age (in years) and the repair cost (in dollars) exceeds $5000, replacement is typically recommended.

2. How Does the Calculator Work?

The calculator uses the simple formula:

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 the Rule

Details: This rule helps homeowners make cost-effective decisions by balancing repair costs against the benefits of a new, more efficient system.

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 economical.
