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

67 degrees is 67 degrees but you can’t feel temperature. What 67 degrees feels like is relative to the ambient temperature because you feel the exchange of heat not the temperature. If it’s colder out 67 feels warm because you’re gaining heat, if it’s hot out 67 will feel cool because you’re losing heat.
