What to do first
Turn the AC off at the thermostat and do not keep resetting the breaker to see if it holds. Notice whether the breaker trips immediately, after the outdoor unit tries to start, or after the system has run for a while.

AC breaker keeps tripping? Stop resetting it over and over.
A breaker trip is a protection clue, not something to keep forcing. If the AC trips when cooling starts, hums, buzzes, smells hot, or will not stay running, text the details and start with a diagnostic.
When to stop and call the right emergency path
If you smell electrical burning, see smoke, hear arcing, or the breaker panel feels unsafe, stop using the equipment and call the appropriate emergency or utility path. Do not wait on a normal service visit for an active electrical safety concern.
Why this needs a real diagnostic
Breaker trips can involve a weak component, motor trouble, compressor startup problems, wiring issues, a short, or a system pulling more than it should. The $95 Springfield Diagnostic gives Scott a safe starting point before repair pricing is discussed.
