Snowstorms and Furnaces03/17/2016 Winter in Marshall isn’t done yet. Mother Nature can typically be unpredictable. While it could be nice one day, the next day could surprise us with snow. When this happens, you can help avoid the need for surprising furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your house. However, there is a difference between these two. 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 correct and safe operation. Once in a while the intake and exhaust pipes of high efficiency units leave through the side of your residence or vertically through the roof. When this is the case, you’re susceptible to 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 planned to automatically shut off if these pipes are blocked.) To stop air flow problems during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Look at the area occasionally and move any snow that has fallen into the cleared area. We understand the weather in Marshall can change on a daily basis during the last few weeks of winter and that weather impacts the operation of your furnace.
