Why won't my AC turn on at all?+

Start with the basics: check your thermostat is set to COOL with the temperature below room temp, check both breakers (indoor and outdoor), and check the disconnect box near the outdoor unit. If all look fine, you likely have a failed capacitor, contactor, or control board.

Why does my AC breaker keep tripping?+

Repeated breaker trips indicate a serious electrical issue — a short in the wiring, a failing compressor drawing too much current, or a ground fault. Do not keep resetting it. Call an HVAC technician to diagnose the root cause.
