I just replaced both of my run capacitors in my condenser unit (single poles, separate for compressor and fan) and I want to add a hard start kit.

Problem I'm having is that the capcitors are 370 VAC but all the hard start kits say they are rated from 120VAC-288VAC.

Can I use the hard start kit with a capacitor with a higher VAC?

I'm pretty handy but when I get to technical stuff like this I'm always cautious. Thanks in advance.

Capacitors are always a higher voltage than their input.

Capacitors give it a starting jolt to the motor at a higher voltage.

Many motors use them. The some systems like microwaves use them to combine positive and negative voltage in the thousands of volts, to get a directed 3,000 volts, for the magnetron

A fan does not cost all that much and are pretty easy to change, sounds like you need to replace that first.
