    Heil furnace blower comes on by itself?
    Heil furnace fan just comes on by itself. Never happened before. However I replace the thermostat in February and was wonder if that may be the issue.

    Is this by chance an oil burner? I have seen on some oil burners where you cannot use a power robbing thermostat, as it will mess with the fan circuit control, causing the blower to kick on and off for no good reason. Only fix is to use a non power robbing thermostat. This is a long shot, but something to keep in mind. If you have the install book for the furnace, it would tell about the stat if it were an issue.
