Why outside unit not running happens in Tampa Bay homes
In order of frequency based on thousands of service calls in the Tampa Bay region — the most common issues first. Your St. Petersburg technician will diagnose the real cause in under 30 minutes.
Bad run capacitor
#1 cause by a mile. Swap: $180–$450 including labor.
Tripped outdoor disconnect
The pull-out box next to the condenser can be tripped or pulled. Check it first.
Failed contactor
The contactor doesn't engage when commanded. Replacement: $200–$350.
Compressor failure
If capacitor and contactor are good, compressor is next. Replacement is $2,500–$3,500 — usually means replace the system instead.
When St. Petersburg homeowners should replace instead
Repair makes sense when
- System is under 10 years old
- Repair is under $1,500
- No major component (compressor/coil) failed
- Rest of the system is healthy
Replacement makes sense when
- System is 12+ years old
- Repair would exceed $2,500

- Utility rebates + IRA tax credit swing the math
