your system is short cycling. Check and clean or change your filter. Check thermostat for proper setting. Be sure thermostat is not located on any wall that leads directly to the outside elements or near anywhere that cold air can influence the thermostat. Such as near an exterior door or window. If none of these solve the issue you may have a sizing problem. Check to be sure unit is properly sized for your home, also check for damaged or corroded flame sensor.
