Only on propane. Fan for furnace is 12v and runs off of battery. Some AC units have an electric heater built into them but that mostly only works to take the nip out of a cool morning from what I've read and some AC models allow for that element to be added if that's something you might want to do.

Furnace uses only propane for a heat source. It uses 12v battery power to ignite the furnace and run the fan.
Furnace is the biggest power drain on a battery and can empty a fully charged one in a single night.
