On arrival nest thermostat was sensing a short on the condenser preventing it from starting. On further inspection the dual run capicator was out of tolerance. Replaced shorted contactor and dual run capicator. System running and cooling as I left. Recommended some form of start kit for the condenser as it was pulling 158 amps on start up and the manufacturers max allowable starting amp draw is 153. Compressor savers reduce amp draw by 30-40 percent and soft start kits reduce starting amp draw by 70-90.
