Arrived onsite for no cooling from front two RTU systems. Observed thermostats showing both systems calling for cooling. Went on roof for diagnostic. RTU 1 was not on. Confirmed call for cooling. Compressor was warm and ac came on and measured good pressures. RTU is cooling. Went to RTU 2; compressors warm. System initially off but came on after reset. Measured good pressures. System is cooling
