Luckily in my life, they just work but there’s gotta be way more to it than gas/electricity make air hot, refrigerant/coolant make air cold. Also what is refrigerant/coolant?
Also I’m sure it can vary in application so I’m mainly asking about buildings/residences.

Electric heaters are pretty simple. They use resistance to heat up a wire, and use that to heat the room. They turn electricity into heat energy, basically.
Coolers are a little more complex, but on the simplest level, they take the heat out of the air inside your room and pump that heat outside.
I’m sure someone with more intricate knowledge than me will be able to come up with a better explanation, but those are the broad strokes.
