Auxilary Heat on in mild weather

I have electric heating and cooling in my house. So far in Columbus, Ohio we are having a mild winter. I always have my thermostat set around 58 degrees in the winter time to save on costs. Over the past 2 days or so I've noticed that the auxilary heat has been on - although I noticed it does not blow hot air out of the vents, just room temperature or a little cooler air. If I kick the thermostat up a few degrees to 64 or so, the auxilary heat kicks off and the normal heat kicks on. I don't want to keep my house that warm, but I can't figure out why my auxilary keeps kicking on when the temperature is cooler. The outside temperature has been in the upper 40's during the day, upper 30's at night. I'm going to change the filter on my furnace today, butis there anything else I can do to fix it on my own without calling a tech? Even during the coldest part of winter last year, my auxilary heat rarely came on.

sounds like a problem in the HP is calling for Aux heat. Could be anything like a bad defrost board or sensor to low on refrigerant. Call a Pro.
