Why will your AC not turn on?
Possible causes include thermostat power or settings, a tripped disconnect or breaker, a condensate safety switch, a failed capacitor or contactor, control-board problems, wiring faults or equipment protection that has opened.
The symptom becomes more specific when you know whether the thermostat display is on, whether the indoor blower runs and whether the outdoor unit makes any sound when cooling is requested.
- ✓Thermostat or low-voltage control problem
- ✓Electrical supply, disconnect or protection issue
- ✓Condensate safety, capacitor, contactor or control fault
What can you safely check before AC service?
Confirm the thermostat is set to cooling and that the setpoint is below room temperature. Check whether the thermostat display is powered and whether a clearly labeled HVAC breaker has tripped.
If a breaker trips again after being reset once, stop resetting it. Repeated electrical trips need diagnosis rather than repeated attempts to force the equipment to run.
Is the indoor unit running but the outdoor unit off?
If the indoor blower runs but the outdoor unit does not, the problem may be concentrated in the outdoor cooling circuit or its controls. If nothing runs, the issue may be broader and can involve thermostat power, controls, safety switches or system power.
A clear description of which equipment responds can shorten the path to the correct AC repair check.

Questions homeowners ask before HVAC service
Get quick answers about common HVAC problems, likely service needs and the next step that makes sense.
Why will my thermostat turn on but the AC does nothing?
The thermostat may be sending a cooling call while a safety, control, electrical or equipment component prevents the system from starting.
Should I keep resetting the AC breaker?
No. If the breaker trips again, leave it off and have the cause diagnosed.
Can a clogged drain stop an AC from starting?
Some systems use a condensate safety switch that can interrupt cooling when the drain backs up.
What if only the outdoor unit will not start?
That can point toward outdoor power, controls, capacitor, contactor, motor or protection issues, but diagnosis is required.
