Why is furnace blowing cold air?
If it's blowing intake-temperature air, either you've got the fan alone switched on or the heating part isn't working for some reason. If it's a gas furnace, the pilot light may have gone out, or the gas may be shut off somewhere (at the furnace itself, at the emergency shutoff for the house, or possibly at the main inlet). If it's blowing actually COLD air (colder than intake), then you've probably got central air and you've somehow managed to turn on the air conditioner.
