It's easy to just turn up the dial on the thermometer in the living room and forget about what's powering the heat.....Until it all goes wrong! When it gets really cold out, furnaces are put through their paces, working overtime to keep homes warm. You should clean out the furnace filter — once a year for larger ones and once a month for smaller filters during the winter months. Another tip is to make sure snow is cleared away from vents and pipes on the exterior of your house. Those pipes connect to the furnace. If snow or ice gets inside, the furnace is going to shut down! Most furnace parts require a professional experienced repair person, but basic regular maintenance can keep the heat on.
Stay warm during the freeze.
