Snowstorms and Furnaces03/17/2016 Winter in Baltimore isn’t finished yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could change to snow. When this take place, you can help elude the need for surprising furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your home. However, there is a difference between both of these. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s important for air to be able to flow freely to ensure proper and safe operation. Sometimes 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 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 designed to automatically shut off if these pipes are blocked.) To prevent air flow issues during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Look at the area often and remove any snow that has fallen into the cleared area. We realize the weather in Baltimore can change on a daily basis during the last few weeks of winter and that weather may impact the operation of your furnace.
