Why is my furnace blowing cold air? -Pilot.
One of the simplest fixes to this problem is to check if your pilot is still on. On some occasions, the furnace’s pilot will fail to light or go out during heating. Without the pilot burning, there is nothing to heat the air, which will cause cold air to filter through the heater. An easy way to fix this is to simply reset your furnace. If this fails to light the pilot, you may have a dysfunctional pilot and should look at getting it replaced by professional.

Why is my furnace blowing cold air? -Start Up.
If you are asking why is your furnace blowing cold air, it could be as simple as giving it time to heat up. Often times, when you just get your furnace going, the cold air sitting in the ducts has to blow out first. So give it 10-20 seconds for the hot air to start blowing through. Many times you will find that this fixes your problem.
