Snowstorms and Furnaces03/17/2016 Winter in Winchester isn’t finished yet. Mother Nature can typically be unpredictable. While it might be nice one day, the next day could dump snow on us. When this happens, you can help avoid the need for unexpected 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 take fresh air from the outdoors into your house, which means it’s important for air to be able to move freely to ensure proper 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 case, you’re at risk of having heavy snowfall bury them, which will obstruct 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 stop air flow problems during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Take a look at the area regularly and clear any snow that has fallen into the cleared area. We know the weather in Winchester can change frequently during the last few weeks of winter and that weather may impact the operation of your furnace.
