It's interesting all the permutations there are out there. We have gas from PG&E. Our house has an electric clothes dryer, gas stove with dual-fuel oven, gas furnace, and gas water heater. No air-conditioning other than a portable unit for "emergency" heatwave and AQI events. Our furnace is ancient, and the winter gas bill is the painful part.

I have a long term interest in full electrification, but find the process daunting due to the interlocking set upgrades. Between insulation envelope upgrades and electrical system upgrades, there is a lot of potentially disruptive work needed to even allow permits to be issued for heat-pump HVAC and water heater or fully electric kitchen.

If the internal wiring also needs much work, it threatens to be almost as invasive as a gut renovation. Then, I ponder what other work we'd want to piggyback on it. But then it all sounds too much for life and budgets, so we procrastinate...

Yep, when I was in the bay area, we had a gas furnace that was built in week 53 of the year before the 78% efficiency standard took effect. Our plan was to put in a heatpump to replace it when it stopped working and get A/C to manage (at least) the heatwaves, but it kept going, so you know. That house was built in 1907 and had an unfinished basement for the original footprint and a generous crawl space for the addition --- wiring would have been pretty simple, but it would still be a lot of investment to replace something that was working ... of course a heat pump system would be way more than replacing like for like.
