The compressors on full house-scale non-split heat pumps are same power draw as AC units, which is many amps more than the peanuts a furnace fan uses, but if OP has an AC unit, the heat pump also replaces it.
I get the complexity though. If I want to upgrade my home to have service for charging electric cars, and all electric heat/cool, the amperage draw is high enough that it would require an upgrade from “consumer”-level to “business”-level power input.
If you’ve got 100 amp service, as is typical for US homes, it’s in theory possible to do things like set up your EV charger to pause when the dryer or oven is running, and end up without the need for a new breaker box.
You might be able to use the breaker that the gas furnace fan is using!

I would think a full house forced air furnace would have a 60ish amp breaker which can run a herfy heat pump. I could be wrong though.
