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

It should. But it’s not perfect. Plus, you’re not setting the air blowing from the vents to be 67 degrees. You’re telling the ACC you want the *average* of your car to be 67 degrees. It’ll still feel different depending on the weather outside though. Radiation is a big part of temperature that we often don’t consider. If the sun is shining and it’s hot out, you’ll be bombarded with radiant heat from outside, and the opposite if it’s really cold outside.
