The 50% Rule — The Simplest Starting Point
If the cost to repair your AC exceeds 50% of what a new system would cost, replacement is almost always the smarter financial choice — especially for systems over 10 years old. Example: if a new system costs $8,000 and your repair quote is $3,500+, you’re better off replacing.
The Age Rule — How Old Is Your System?
In South Florida, AC systems age faster than anywhere else in the country. Year-round operation, humidity, salt air, and heat put more strain on equipment per year than northern climates. Typical lifespan in Palm Beach and Broward County: 12–15 years. Once a system passes 12 years, even small repairs deserve a replacement conversation — because more problems are coming.
Repair vs. Replace — Decision Guide
| Situation | Recommendation |
|---|---|
| System under 8 years old, repair under $500 | Repair |
| System 8–12 years old, repair under $1,000 | Repair — with a plan to replace in 2–3 years |
| System over 12 years old, any compressor repair | Replace — compressor failure is end-of-life signal |
| R-22 refrigerant system needing recharge | Replace — R-22 is phased out, extremely expensive |
| Second major repair in 2 years | Replace — pattern of failure will continue |
| FPL bill increasing despite normal use | Replace — efficiency loss rarely improves with repair |
| System under 10 years, capacitor or minor repair | Repair — these are wear items, not system failure |
The Real Cost of Keeping an Old System
A 15-year-old system running at SEER 10 vs. a new Ruud RD18 at SEER2 18 isn’t just about reliability — it’s about your FPL bill every single month. At South Florida’s electricity rates, the efficiency difference can be $80–$150/month. Over 10 years, that’s $9,600–$18,000 in extra electricity costs — more than the cost of a new system.
