Electrical Troubleshooting
AC Keeps Tripping the Breaker?
If your AC breaker trips once after a Tampa thunderstorm: usually just a voltage spike. Reset and move on. If it trips repeatedly: something is wrong. Do NOT keep resetting, you can damage the compressor or cause a fire.
Quick Answer
AC breaker tripping in Tampa = 4 causes: (1) capacitor failure (starting amp spike), (2) compressor pulling too many amps (failing), (3) shorted wiring, or (4) breaker itself is weak/failing. Don’t keep resetting, investigate first. Call (813) 343-2212 for same-day electrical diagnosis.
4 Reasons Your AC Breaker Trips
Failed Capacitor
Symptom: AC tries to start, hums, trips breaker within seconds.
Capacitor replacement $279. Most common reason.
Compressor Drawing Too Many Amps
Symptom: AC runs for a few min then trips. Usually 10+ year old system.
Compressor boost kit $459 or full compressor replacement $649+.
Shorted Wiring
Symptom: Trips immediately, may smell burning.
Electrical diagnosis + rewire. $299-$799 depending on extent.
Weak/Failing Breaker
Symptom: Trips randomly, even when AC isn’t running hard.
Circuit breaker replacement $349.
What to Do Right Now
- Reset breaker ONCE. If it trips again within 10 minutes, STOP.
- Don’t keep resetting, you risk damaging compressor or causing electrical fire.
- Turn off AC at thermostat, leave breaker off.
- Call Home Therapist, electrical issues are not DIY.
Capacitor fix: $279. Circuit breaker: $349. Compressor-related: $459-$2,000+. Electrical rewire: varies by job.
FAQ
Is it safe to keep resetting the breaker?
No. Each trip-and-reset can damage the compressor ($649+ to replace) or shorted wiring can spark a fire.
Why does it trip in summer but not winter?
Compressor works harder in Tampa summer heat. Marginal issues (failing capacitor, weak compressor) only show under load.
Can a surge protector prevent this?
Surge protector ($469) prevents voltage-spike damage but doesn’t fix an already-worn AC component.
Can I replace a breaker myself?
Not recommended. Electrical panel work requires permits in most Tampa counties + knowledge of proper wire gauging.
What if my HVAC breaker is different size than manual says?
Could be previous wrong install. We verify breaker matches AC specs and code during diagnosis.
