I haven’t had a central air system that does this. Mine have always had return vents and it just cycles internal air. I’m actually very curious about more intelligent systems. Those that can: - bring in outside air on occasion to freshen things up - negotiate the best way to cool a home depending on outside air. It drives me mad when my AC kicks on and it’s actually colder outside.

As a kid I always wanted an external vent on the refrigerator that pulled in outside air when it was cold enough.
