cars that are equipped with ac are supposed to run when the heat selection is on : max a/c , a/c , mix or defrost. the ac pump dries the air that flows through it which helps to clear the windshield and also to help to feel cooler in the summer . i have pulled the plug on the compressor before to turn it off during the winter months but it is just fine to run
Also, heat settings keep the compressor running to prevent it from seizing. The number 1 cause of compressor failure was due to lack of use during the long winter months.
