Right; I was born in Europe and per-room heating was the norm; but I've lived in North America for last 30 years, and this is apparently still not something we have figured out - in Canada, vast majority of houses have central furnace with central fan. I've had several HVAC professionals come and despite my "Shut up and take my money!!!" attitude, basically none of them wanted to even bother giving me a quote to install something smarter and more granular (and why would they, when they can make good honest living doing routine work swapping furnace and AC control boards etc).

Yeah, I don't think I've ever seen a place in the US where you could control individual rooms. With forced-air heating, it seems like all it would take would be a way for the room thermostat to open and close the vent.
