Hi my name is Robert....

This sounds like a thermostat issue if it works good when you set the temp higher, you may have an anticpator under the cover for the thermostat that will allow you to adjust when the furnace is able to kick on. I am not sure which thermostat you have but I would pop the cover off and look for a screw that you can adjust, if not I would try a new thermostat on this.....
