It can be quite common for homeowners to automatically call a professional when something goes wrong with their American Standard air conditioning unit.

Start your troubleshooting by checking the thermostat to ensure it is set correctly for cooling operation. It should be on cool and set lower than the current room temperature. Are the outside and inside fans running? If neither of them is running, a circuit breaker could have been thrown. Make sure the breakers are indeed on. When the breakers are still on and the unit is not running, the thermostat, control board, or wires between the two could be having an issue. Test the thermostat by taking the cover off and attempting to get the unit to kick on manually. If it will kick on, a new thermostat or rewiring could fix the problem.
