Snowstorms and Furnaces03/17/2016 Winter in Saint Peters isn’t done yet. Mother Nature can typically be unpredictable. While it might be nice one day, the next day could dump snow on us. When this occurs, you can help dodge the need for surprising furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your residence. However, there is a difference between these two. High-efficiency furnaces also take fresh air from the outdoors into your house, which means it’s significant 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 exit through the side of your house or vertically through the roof. When this is the case, you’re in danger 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 meant to automatically shut off if these pipes are blocked.) To avoid 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. Take a look at the area occasionally and clear any snow that has fallen into the cleared area. We realize the weather in Saint Peters can change every day during the last few weeks of winter and that weather can effect the operation of your furnace.
