⚠️ Gray Zone: Need More Info
Your system is in the tricky middle years. The right choice depends on repair cost, energy efficiency, and whether you're seeing repeat failures. Generally: if repair is under $2,000 and no prior issues, repair. If over $3,000 or frequent problems, replace.

🔄 Likely Best Move: Replace
At 15+ years, most systems are near end-of-life. Even a successful repair often leads to another failure within 12-24 months. Modern systems are also 30-50% more efficient, saving on energy bills.

Real Example from San Diego
Situation: 12-year-old AC, compressor failure, $2,800 repair quote.
Analysis: Compressor is the most expensive part. System is middle-aged. If no prior issues and regular maintenance, repair might be okay. But at $2,800, you're 40-50% of the way to a new system with warranty and better efficiency.
Recommendation: Get a replacement quote. If new system is under $7,000, replace. If over $8,000, consider repair IF no other issues exist.
