Cooling maintenance performed on split cooling system. Checked electrical and mechanical components, recorded refrigerant readings, and measured temperature split. System has a slight refrigerant restriction past the metering device and is impacting cooling efficiency at normal heat loads and overheating the compressor. Also noted very weak fan motor capacitor, worn motor, melted disconnect, faulty contactor and overheating compressor. Created estimates for repairs but, due to age and condition, recommend comfort consultation for replacement.
