Snowstorms and Furnaces03/17/2016 Winter in Lawrence isn’t done yet. Mother Nature can typically be unpredictable. While it can be nice one day, the next day could surprise us with snow. When this happens, you can help avoid the need for unforeseen furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. Nonetheless, there is a difference between these two. High-efficiency furnaces also bring fresh air from the outside into your house, which means it’s important for air to be able to flow freely to ensure proper and safe operation. Occasionally the intake and exhaust pipes of high efficiency units exit through the side of your home or vertically through the roof. When this is the case, you’re susceptible to having heavy snowfall bury them, which will obstruct 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 prevent air flow obstruction during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Take a look at the area often and move any snow that has fallen into the cleared area.
