Since 105 is 1uF, wouldn't 225 be 2.2uF?

It is, but the original was 2.5uF.
But Max came up with 2.25uF. I was wondering where the third significant figure came from?

The principle behind the start/run winding on a PSC motor is it provides a degree of phase shift in the start winding WRT the run winding, the phase angle difference is a produced by the value of the cap and the inductive reactance of the winding, the ideal is a 90° shift.
The value required is not super critical, the slight increase you May have in current should not be a concern.
