Monitor suction pressure, discharge pressure, temperature difference across the evaporator (typically 15–20°F under normal conditions), and condensate drainage from the drain pan. Measure compressor amperage and compare itto the nameplate rated load amps. A compressor drawing significantly higher or lower amperage than specified may indicate underlying mechanical issues. Document all readings in the system log for future reference and trend analysis.
