Eli5: why does warm 67 degrees feel different than cool 67 degrees

Question

I’m in my car and I set the AC to 67 it feels different than if I set my heat to 67. Shouldn’t 67 degrees be 67 degrees

Answer 1

Because you don’t feel temperature. You feel the relative change in temperature. You feel heat, either entering or leaving your skin.

Also, AC and heaters don’t pump out the temperature air you set, they pump out air past what you set, so it can get to your desired temperature faster, then it shuts off or adjusts.
