A compressor that hums and trips is the classic failed start capacitor on units of this age. It is a cheap part but it sits next to mains-voltage components that store charge, so it is not an owner replacement.
Owners can clean filters and coils gently and make sure the drain path is clear. Electrical repairs and refrigerant work need a technician with the unit isolated.
