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 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 HVAC Replacement Timing

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

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 recommend repair or replacement.

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 energy efficiency improvements and your system's maintenance history.

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

Q3: Should I consider energy efficiency when deciding?
A: Yes, newer systems are often significantly more efficient, which may justify earlier replacement.

Q4: What if my system is very old but the repair is cheap?
A: Even if the $5000 rule doesn't recommend replacement, an old system may be nearing the end of its lifespan.

Q5: How accurate should my repair cost estimate be?
A: Get a professional estimate for major repairs. For minor repairs, you can use the quoted cost.
