Snowstorms and Furnaces03/17/2016 Winter in Aurora isn’t finished yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could dump snow on us. When this happens, you can help dodge the need for unforeseen furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. 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 vital for air to be able to move freely to ensure correct and safe operation. Once in a while 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 case, you’re in danger of having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t worry, though. High efficiency furnaces are planned to automatically shut off if these pipes are blocked.) To stop air flow problems during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Take a look at the area often and clear any snow that has fallen into the cleared area. We realize the weather in Aurora can change on a daily basis during the last few weeks of winter and that weather can effect the operation of your furnace.
