Hey Charles! Thank you for calling Kings electric & a/c for your electrical repairs. Today I was called out because you’re having issues with your a/c breaker. After troubleshooting and opening everything up, I came to the conclusion your problem is at your thermostat. We were able to replace it with a new one and now the system turned on once again. If you have any questions or concerns, please give us a call. Your electrical technician, Xavier
