Your AC just failed. The tech is standing in your home with a repair estimate. In the July heat, with your family uncomfortable, you have to make a significant financial decision quickly. Here's the framework we use to help Palm Beach homeowners make this decision clearly.
Auto mechanics use the “$1,000 rule” — don't spend more on a repair than the car is worth. HVAC contractors use a variation called the 5,000-mile rule: multiply the age of the system by the repair cost. If the result exceeds $5,000, lean toward replacement. A 10-year-old system with a $600 repair: 10 × $600 = $6,000 — borderline case. A 12-year-old system with a $500 repair: 12 × $500 = $6,000 — consider replacement.
In South Florida's demanding climate, the average useful life is 12–15 years. A 12-year-old system that needs a major repair will likely need another within 1–3 years.
R-22 (Freon) was phased out under EPA regulations. Remaining supplies are extremely expensive — sometimes $200+ per pound. If your system uses R-22, replacement almost always makes more economic sense than a recharge.
The compressor is the most expensive component. A new compressor often costs $1,500–$3,000 installed — sometimes 50%+ of a new system cost. In an aging system, spending this much rarely makes sense.
One major failure can be unlucky. Two within 24 months is a pattern. Systems that have had multiple major repairs are in a reliability death spiral.
Systems installed before 2015 typically have SEER ratings of 10–13. Modern systems hit 18–24+ SEER. Replacing a 10-SEER system with a 20-SEER system can cut your cooling bill by 40%.
A relatively young system with a minor failure (capacitor, contactor, minor refrigerant leak) is usually worth repairing — it still has 5–7 years of useful life ahead.
Capacitors, contactors, thermostats, and minor electrical repairs are inexpensive and extend the system's reliable life meaningfully.
A well-maintained Carrier or Trane system that has had zero previous failures and suddenly needs a capacitor is a different situation than a budget brand with a history of issues.
If a certified technician tuned up the system recently and found no concerning indicators, a minor repair makes more sense.
There's no universal right answer. But the most important thing is to make this decision without the pressure of a broken-down system in July heat. If your system is 8+ years old and showing any of the replacement indicators above, get a replacement estimate now — before the next breakdown — so you're making a calm, informed decision rather than a panicked one.
Our technicians provide straightforward repair-vs-replace recommendations with no pressure — just the facts for your specific situation.
