Of course AC is not just for cooling… I know the AC dehumidifies the air which keep the windows from fogging up… But what about on normal cold days? I can have the AC button on with the heat or I can just run the heat with the AC button off.
I never know which I should be doing . Should I always keep the AC on? Regardless if I’m heating or cooling? Is it better for the car or compressor or something?
