As we head into winter, it's a good idea to learn a thing or two about the machine that will provide us with heat and comfort throughout the cold, winter days—most likely, a gas furnace. The more you know how a furnace works, the better you can troubleshoot it if something goes wrong. And since space heating accounts for roughly 45% of energy bills paid by U.S. homeowners, it's no wonder why people want to know more about how they work (U.S. DOE).
