Snowstorms and Furnaces03/17/2016 Winter in Rocky Mount isn’t quite over yet. Mother Nature can certainly 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 unforeseen furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your home. Nonetheless, 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 transfer freely to ensure correct 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 block 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 obstruction during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Take a look at the area often and remove any snow that has fallen into the cleared area. We realize the weather in Rocky Mount can change on a daily basis during the last few weeks of winter and that weather can effect the operation of your furnace.
