When to Replace vs Repair Air Conditioner

Should I replace or repair my AC? Replace systems 10+ years old when repair costs exceed $800, or systems requiring second major repair within 12 months. Repair systems under 8 years old with single-component failures costing under $600.

Replacement Decision Matrix

Compressor failure indicator: Compressor replacement costs $730–$1,130 for split systems. Systems 8+ years old with compressor failure should be replaced—remaining components likely fail within 2–3 years requiring additional $500–$1,200 repairs.

Energy efficiency consideration: Upgrading 3-star system (2005–2010) to 6-star current system saves $560–$840 annually through 40–50% electricity reduction. Replacement recovers premium cost within 3–5 years through energy savings plus government rebates.
