1. What is the $5000 Rule?

The $5000 rule is a guideline to help determine whether to repair or replace an HVAC system. 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 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 HVAC Replacement Timing

Details: Proper timing of HVAC replacement balances repair costs against the benefits of a new, more efficient system. Replacing too soon wastes money, while waiting too long may lead to higher energy bills and frequent repairs.

4. Using the Calculator

Tips: Enter your HVAC system's age in years and the estimated repair cost in dollars. The calculator will determine if replacement is recommended based on the $5000 rule.

5. Frequently Asked Questions (FAQ)

Q1: Is the $5000 rule always accurate?
A: It's a guideline, not an absolute rule. Consider other factors like system efficiency, expected lifespan, and frequency of repairs.

Q2: What if my system is very old but repair is cheap?
A: Even if the product is below $5000, very old systems (15+ years) may still warrant replacement for efficiency gains.

Q3: Does this account for energy efficiency improvements?
A: No, this is purely a cost calculation. Newer systems may save enough in energy costs to justify earlier replacement.

Q4: Should I consider seasonal timing for replacement?
A: Yes, off-season replacements (spring/fall) may offer better pricing and availability than peak seasons.

Q5: What other factors should I consider?
A: Consider remaining system lifespan, maintenance history, refrigerant phase-outs, and available rebates for high-efficiency systems.
