Snowstorms and Furnaces03/17/2016 Winter in Chicago isn’t quite over yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could dump snow on us. When this happens, you can help avoid the need for surprising furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your home. However, there is a difference between both of these. High-efficiency furnaces also pull fresh air from the outside into your house, which means it’s important for air to be able to transfer freely to ensure appropriate and safe operation. Once in a while the intake and exhaust pipes of high efficiency units leave through the side of your home or vertically through the roof. When this is the case, you’re at risk of having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t panic, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To stop air flow problems during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Examine the area occasionally and remove any snow that has fallen into the cleared area. We realize the weather in Chicago can change on a daily basis during the last few weeks of winter and that weather impacts the operation of your furnace.
