Does orange country pay less than half of San Diego? Both using the same gas provider? I'm surprised to hear that. Prices in the bay area were in the mid 40c per kWh when I lived there five years ago and folks in sf were the same. I assumed this was due to sin taxation.

Fwiw brief googling doesn't find anything to support the claim that OC is cheaper than San Diego. Con ed time of use rates are quoted state-wide here: https://www.coned.com/en/accounts-billing/your-bill/time-of-use Can you provide some source for your claim it's cheaper in OC?

It's not about the size of the pump, it's about the chemical technology used. Newer chemistries stay efficient to lower temperatures compared to older ones. Some are even efficient down below 0F.

(Conversely, a larger pump may not even help if you have a really old chemistry. Your pump would have to switch to backup resistive heat at the point where it's chemistry stops being efficient.)
