My AC/Heater is blowing the wrong temperature air

If your unit is blowing warm air when it should be cold, or cold air when it should be warm, your fan switch may be set to "on" instead of "auto." Make sure to set your switch to auto to see if this helps! Also, be sure and to double-check your thermostat settings! Someone may have tampered with it!
