It’s not necessary for the room doors to be facing each other for cross ventilation. But, if they do face each other, then you’ll notice an air tunnel there.

HVAC’s are a pretty smart way to ventilate your house. They take in air and give out air at your preferred temperature. But you should only rely on HVAC’s if they’re centralized.
