Tony was the best, thanks guys
Found the system partially froze up. Dirty air filter in the furnace and thermostat set to 68 degrees. Keep the thermostat no lower than 73 degrees and replace the thermostat as often as it gets dirty.
Found the furnace not lighting up properly. Found the gas orifices were never changed out and the wrong size. Replaced the gas orifice with the correct size and verified proper operation
Furnace blower motor was not running. Checked circuit board to make sure it was working properly. Found the run capacitor was bad. Replaced capacitor and blower motor runs properly
