Snowstorms and Furnaces03/17/2016 Winter in Winnsboro isn’t done yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could surprise us with snow. When this occurs, 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 residence. Nonetheless, there is a difference between the two. High-efficiency furnaces also bring fresh air from the outside into your house, which means it’s vital 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 residence or vertically through the roof. When this happens, you’re susceptible to having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t panic, though. High efficiency furnaces are planned to automatically shut off if these pipes are blocked.) To stop 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 clear any snow that has fallen into the cleared area. We understand the weather in Winnsboro can change on a daily basis during the last few weeks of winter and that weather can effect the operation of your furnace.
