Most if not all single-phase compressor motors use capacitors for starting. Most three-phase compressors do not use capacitors; but if they do, it is for improving power factor rather than starting.

Usually no, but it is conceivable that power factor correction capacitors might be present.

Very unlikely.

they sometimes use for capacitor-assisted starting of induction motor. Same could be used for PFC once started.
