I would check the PF during start-up and steady operation. Can use a
current doughnut and compare it to the line voltage. If the peak current is
very high and line sags too much on start-up you can use a AC cap on the
input. But I would not go for the fancy ones. I would get a regular AC
polypropylene cap (47uF-220uF) and leave it in in the circuit, it might
improve the PF during the normal operation.

It sounds like a way to convert a 3 phase motor to a capacitor start
motor. It might help an old underloaded motor with a bad power factor.
It would probably destroy an Energy Star air conditioner.

Just another gimmick. Maybe even bad for your compressor if it a
capacitor run type.
