1. What is the $5000 Rule?

The $5000 rule is a guideline used in the HVAC industry 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 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 Timing

Details: Making the repair/replace decision at the right time can save thousands in unnecessary repairs or premature replacement. Other factors like energy efficiency improvements should also be considered.

4. Using the Calculator

Tips: Enter your HVAC system's age in years and the estimated repair cost in dollars. The calculator will apply the $5000 rule to make a recommendation.

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, maintenance history, and your local climate.

Q2: What's the average lifespan of an HVAC system?
A: Typically 15-20 years, but proper maintenance can extend this while poor maintenance can shorten it.

Q3: Should I always replace if the product exceeds $5000?
A: Not necessarily. If your system is well-maintained and the repair is minor, you might choose to repair regardless.

Q4: How accurate should my repair estimate be?
A: Get a professional estimate for best results. Online calculators can't account for all variables in your specific situation.

Q5: Does this account for energy efficiency improvements?
A: No. Newer systems are often significantly more efficient, which could justify earlier replacement.
