Is it normal for HVAC lines to be completely white and frosted?

Hola. I dont know much about the heating and cooling system. I just know I had AC in the summer and in the winter I have heating. I am in NJ where temps have fluctuated anywhere from 25F to 48F. Images attached. I noticed when I turn my car on that the lines are completely white and frosted. Is this a problem?

No, my guess is that you're using your defroster which will kick in your AC compressor. Those lines run from the compressor to your AC evaporator. The evaporator is great at getting moisture off of your windshield when it's damp outside.
