Ensure that the control unit dial is positioned at the south end (opposite to the low temperature setting direction) and that the room temperature is getting higher than the set heating point. In addition, a possible reason may be related to the connection wires from the thermostat to the furnace, even if the HVAC unit is working as expected.

If the furnace is blowing cold air then you should check that at the pilot light and igniter. Touch the pilot light or if you cannot see the pilot light then see if the tip of the burner is covered and if any resale signs are present. Fix the pilot light if necessary, and refer to the instructions provided by the appliance manufacturer. If (the pilot light) light(s) are on but the heater is not turning on, it is possible that there is a problem with the igniter.
