AC Repair vs. Replacement: How to Decide in 2026
The exact rules of thumb HVAC pros use to recommend repair, replacement, or 'limp through one more summer.'

The $5,000 question every August
Your AC dies on the hottest day of the year. The tech quotes $1,400 to fix it or $9,500 for a new system. What's the right call?
The 50% rule
If the repair costs more than 50% of replacement and the unit is 10+ years old, replace it. Older R-22 systems that need a refrigerant leak fixed are almost always a replace.
What it really costs
- Capacitor / contactor replacement: $150–$400. Almost always worth it.
- Refrigerant recharge (R-410A): $300–$700. R-22 is now $1,500+ if you can find it.
- Blower motor: $450–$1,200.
- Compressor: $1,800–$3,500. Usually pushes you toward replacement.
- Full system replacement (3 ton, 16 SEER): $7,500–$12,500.
Signs it's time to replace
- 10+ years old AND any major component failed
- Energy bills creeping up 10–20% year over year
- R-22 refrigerant system (phased out)
- Two service calls in one season
- Rooms that never cool evenly even after a tune-up
When to repair
- Unit is under 8 years old
- Repair cost is under $600 and unit is under warranty
- The fix is a known wear item (capacitor, contactor, thermostat)
Don't forget to ask about
- AHRI matched indoor + outdoor system (mismatched = lost efficiency and warranty)
- Line set flush if upgrading from R-22 to R-410A
- Manufacturer rebates ($300–$1,500 in many regions)
- Heat pump tax credits under the IRA (up to $2,000 federal)
