Repairing refrigeration systems can be quite challenging at times, especially when a system has multiple problems. In these situations, it is always best to try to identify all of the system’s issues on the initial inspection, but this is not always possible. The first problem observed may not always be the only issue or the major issue. Having patience is definitely a plus during the troubleshooting process, as it is easy to rush to an early conclusion and overlook other problems. Having to explain that there are additional problems at an additional cost — after your initial discussion — can lead to an unhappy customer.
