So Japanese people call the HVAC system the air conditioner even when they're using it for heat and not cold?

Well, air conditioner "conditions" the air so it could be heat, it could be cold, it could be humidity, you name it.
I'd bet it's the same for many languages (in Russian we just shorten it to "conditioner").
When you think about it, "HVAC" is kind of a redundant term.
