Snowstorms and Furnaces03/17/2016 Winter in Erie isn’t done yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could dump snow on us. When this occurs, you can help dodge the need for unexpected furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your house. But, there is a difference between the two. High-efficiency furnaces also bring fresh air from the outdoors into your house, which means it’s significant for air to be able to flow freely to ensure proper and safe operation. Sometimes the intake and exhaust pipes of high efficiency units exit through the side of your residence or vertically through the roof. When this happens, you’re at risk of having heavy snowfall bury them, which will obstruct 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 avoid air flow obstruction during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Look at the area often and remove any snow that has fallen into the cleared area. We realize the weather in Erie can change on a daily basis during the last few weeks of winter and that weather may impact the operation of your furnace.
