An electric heat pump by nature has a lot more parts.

A gas furnace is just a few sensors, a burner, a fan, and a box to do it in.

I think you might be underestimating the # of components in a modern furnace.

I'm intentionally being reductive, but I have worked on several furnaces and gas furnaces are an order of magnitude simpler than their respective heat pump.

... gas furnace + A/C compressor is another story.
