Snowstorms and Furnaces03/17/2016 Winter in Rapid City isn’t finished yet. Mother Nature can typically be unpredictable. While it could be nice one day, the next day could change to snow. 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 directed outside of your home. But, there is a difference between these two. High-efficiency furnaces also pull fresh air from outside the home into your house, which means it’s vital for air to be able to transfer freely to ensure proper 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 case, you’re at risk of having heavy snowfall bury them, which will hinder the free flow of air your high-efficiency furnace needs. (Don’t worry, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To stop air flow issues during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Look at the area regularly and clear any snow that has fallen into the cleared area.
