Snowstorms and Furnaces03/17/2016 Winter in Marshalltown isn’t done yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could change to snow. When this take place, you can help dodge 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 take fresh air from the outdoors into your house, which means it’s significant for air to be able to move freely to ensure appropriate and safe operation. Sometimes 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 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 stop air flow issues 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 often and move any snow that has fallen into the cleared area.
