Arrived onsite for no cooling service call on second floor system. Homeowner turned thermostat down. Heard inside unit come in. Outside condenser did not come on. Performed diagnostic. Did not measure any voltages to the system. Had the homeowner check the circuit breaker which was tripped the condenser. Confirmed operation, measured amps at 9. Measured 410a pressures at 110/240. System is cooling. Observed green dye on the service valves. Homeowner has no recollection of recharging the system or anyone adding dye to the system.
