Snowstorms and Furnaces03/17/2016 Winter in Plainfield isn’t finished yet. Mother Nature can certainly be unpredictable. While it might be nice one day, the next day could surprise us with snow. When this happens, you can help dodge the need for surprising furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your residence. But, there is a difference between these two. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s vital for air to be able to flow freely to ensure appropriate and safe operation. Sometimes 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 situation, 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 fret, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To prevent air flow obstruction 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 regularly and move any snow that has fallen into the cleared area. We know the weather in Plainfield can change on a daily basis during the last few weeks of winter and that weather can effect the operation of your furnace.
