A/C Problem on my new coupe?

Today I noticed something strange while driving to work. The outside temperature was 48 degrees and I had my inside temperature set to 72 degrees. As I put my hand close to the A/C vents, I felt warm air coming out. Is my A/C having a problem? Normally, on a hot day down here in FL, 72 degrees setting blows nice cool air to the touch.

I set the temp to 60 degrees and I felt cold air out of the vents, so it’s not having a problem blowing cold air.

My guess is that since the outside temperature is colder than my inside temperature setting, the A/C has to heat the inside temperature to get to the desired 72 degree setting, thus blowing hotter air. Conversely, on a hot day, the outside temperature is higher and the A/C has to blow colder air to get to the desired 72. I know this may sound obvious, but I’ve never noticed this on my previous cars.

Anyone have some comforting input?

Yes, that is normal that's why they call it climate control. Nothing wrong with it that's the way it's suppose to operate.

You've answered your own question.

It's a climate control system that delivers the correct air temperature in the right mode to meet the temperature setting you make. Air conditioning can work with both warm and cool air and helps dehumidify air.

+1 ... you set your internal temp higher as opposed to the air outside the vehicle... what did u think was going to happen??
