AC Won’t Turn On? What to Check Before You Call

The usual suspects

The panel breaker OR the grey box by the outdoor unit — either one off kills everything.

Dead batteries or a tripped safety cuts the low-voltage circuit; some screens stay on while the AC never hears the call.

A clogged drain trips a tiny safety switch that shuts the system down before water ruins your ceiling.

The three small parts that most often die of old age — quick finds for a tech with a meter.

1
Fresh thermostat batteries, set to COOL, well below room temp.
2
Reset the AC breaker once, firmly off then on. Trips again? Stop — that’s a fault.
3
Check the outdoor disconnect box is pushed in fully.
4
Look for standing water in the pan under the indoor unit — water = tripped float switch = clogged drain.
