My furnace is barely working AND it's making a whining noise.
My gas furnace, a snyder-general gas fired forced air furnace, is barely heating the house; cool air is coming from the vents. I am relying on a gas fireplace at the moment to prevent a sudden drop in temperature.
Additionally, when I woke 25 minutes ago, I heard a whirling, whining, ethereal jet-engine type noise coming from it.
Does anyone know what is wrong with my furnace?
