1. A method comprising: installing at least one component in a refrigeration system; operating the refrigeration system for a predetermined time period; receiving, with processing circuitry, a compressor current of a compressor of the refrigeration system from a compressor current sensor during the predetermined time period; receiving, with the processing circuitry, a compressor voltage of the compressor from a compressor voltage sensor during the predetermined time period; receiving, with the processing circuitry, an ambient temperature with an ambient temperature sensor during the predetermined time period; determining, with the processing circuitry, a condenser temperature based on the compressor current and the compressor voltage; determining, with the processing circuitry, a condenser temperature difference based on the condenser temperature and the ambient temperature; comparing, with the processing circuitry, the condenser temperature difference with a first predetermined range having a high condenser temperature difference threshold and a low condenser temperature difference threshold; and completing installation of the at least one component in response to the condenser temperature difference being between the high condenser temperature difference threshold and the low condenser temperature difference threshold.
