Why Does My AC Keep Tripping the Breaker?
TL;DR: Why Your AC Keeps Tripping the Breaker
If your AC keeps tripping the breaker, your system is likely pulling too much electricity or dealing with an electrical problem.
You can reset the breaker once, but if it trips again, turn the AC off and stop forcing it back on.
Common causes include a dirty air filter, dirty condenser coil, bad capacitor, failing fan motor, compressor problem, loose wiring, or bad breaker.
Call for help right away if you smell burning, hear buzzing, see smoke, or the breaker will not reset.
An HVAC technician should usually inspect the AC first if the breaker trips when the system starts, runs, or tries to cool.
