Snowstorms and Furnaces03/17/2016 Winter in Dresden isn’t done yet. Mother Nature can certainly be unpredictable. While it can be nice one day, the next day could change to snow. When this happens, you can help dodge the need for unforeseen furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. However, there is a difference between the two. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s significant for air to be able to flow freely to ensure appropriate and safe operation. Occasionally 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 situation, you’re susceptible to having heavy snowfall bury them, which will block 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 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 regularly and clear any snow that has fallen into the cleared area.
