Arrived on site and checked in with customer. Inspected air conditioner and found that the evaporator had become dirty from recent renovations and the compressor was locking out on RLA. Capacitor for compressor was failed. With approval, replaced capacitor and cleaned evaporator coil with water. Restarted system, which began cooling. Observed operation to ensure no immediate failure would occur. System currently cooling and motors amping within range. System operational at the end of service.
