Snowstorms and Furnaces03/17/2016 Winter in Scottsboro isn’t quite over yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could change to snow. When this take place, you can help avoid the need for unexpected furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your house. However, there is a difference between the 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 transfer freely to ensure correct and safe operation. Sometimes the intake and exhaust pipes of high efficiency units depart through the side of your house or vertically through the roof. When this is the situation, you’re susceptible to 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 meant to automatically shut off if these pipes are blocked.) To avoid air flow issues during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Look at the area regularly and clear any snow that has fallen into the cleared area. We understand the weather in Scottsboro can change every day during the last few weeks of winter and that weather can effect the operation of your furnace.
