Oh yeah? Then what do you do in the winter? Your heater doesn’t bring in fresh air either. Do you keep the windows open and let all your heat out?
Also what other air conditioners are you comparing against? Because window units also keep the air compressor outside the window with a barrier between the inside part, which takes in air from the room.
All HVAC systems recirculate the inside air, without bringing in fresh air. So please elaborate on which cooling method you would use during these 30°C/100°F days we have to stay cool?

You’re wrong on that one. Ducted air conditioning systems do bring fresh air in, as well as positive inflow and heat recovery ventilation systems.
Not all of them do. It’s mostly industrial units designed to bring in air to create a slightly positive indoor air pressure.
