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 exceeds $5000, replacement is typically recommended.

2. How Does the Calculator Work?

The calculator uses the $5000 rule formula:

Where:

• \( Age \) — Current age of HVAC system in years
• \( Repair Cost \) — Estimated cost of needed repairs 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. 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 and provide a recommendation.

5. Frequently Asked Questions (FAQ)

Q1: Is the $5000 rule always accurate?
A: It's a guideline, not an absolute rule. Consider energy efficiency, system performance, and your local climate as well.

Q2: What if my system is very old but repair is cheap?
A: Even if the product is under $5000, systems over 15 years old may benefit from replacement due to efficiency gains.

Q3: Should I consider SEER ratings when replacing?
A: Yes, newer systems with higher SEER ratings can significantly reduce energy costs, offsetting replacement costs over time.

Q4: Are there exceptions to this rule?
A: Yes, if your system uses outdated refrigerants (like R-22) or has safety issues, replacement may be warranted regardless of cost.

Q5: How accurate should my repair estimate be?
A: Get at least 2-3 professional estimates for major repairs to ensure you're making an informed decision.
