    The thermal mass of the metal, rubber and plastics inside the car will continuously reheat any fresh air that is introduced to the inside. That’s why car air conditioners are so powerful, way more BTUs than your average window unit of a similar size.

      My guy. When you enter a car in the summer, the air is very hot and it takes a couple minutes to cool it down. When you replace the air first using the trick I mentioned, the air is much cooler, so you don’t sit in hot air for a couple of minutes. I’m not saying to do this instead of AC.

      How hard is it to understand this? Cooler air is cooler than hotter air. My god.
