I've often wondered if opening windows while AC is running and outside temp is below inside temp is less efficient than keeping them closed.
My thought is I should keep them closed due to extra load on the AC to dehumidify the outside air. Or open windows and turn AC to fan-only mode to prevent stagnant air in rooms without windows.
