AC Not Turning On: Silent System Checks
If you smell gas or a CO alarm sounds, leave the home and call the gas utility or 911 from outside.
An AC that will not turn on needs the thermostat request and power supply checked before a motor failure is assumed. Confirm the display is on, COOL is selected, and the setpoint is below the room reading. If the system remains silent, record the conditions and arrange a professional diagnosis.
