How every CooperFix repair runs
The mechanic reads the system first: suction and head pressure, superheat and subcooling, amperage on the compressor and the fans, temperature at the product. Those readings say whether the equipment has lost charge, is restricted, cannot reject heat, has a failed motor or control, or a compressor that no longer pumps. The repair follows the readings. Leaks are found and repaired, not topped up. Compressors are condemned by a pump-down test, not by the symptom. Ice is cleared as part of repairing the defrost that let it form.
