No, the grid will never see it.

I work for a power utility, responsible for the automated meter reading of both commercial and residiential accounts.

I don't know of any utility that charges by power factor. We do monitor it, more to keep demands balanced on 3 phase lines, but it's not billed that way. Billing is typically done based upon demand, not reactance.

I have seen plenty of off balance meter reads caused by reactive loads. You can see it at the specific meter, but any negative effect tends to stay at the site; these customers typically have power and current transformers before the meter, so they tend to mitigate the issue.

At a residential site, I really doubt that any type of reactance from an A/C filtering system would be worse than that of a fridge, heat pump, central air compressor, or any other large motors.
