Snowstorms and Furnaces03/17/2016 Winter in Saint Louis isn’t quite over yet. Mother Nature can certainly be unpredictable. While it could be nice one day, the next day could change to snow. When this occurs, you can help avoid the need for unexpected furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your residence. But, there is a difference between these two. High-efficiency furnaces also take fresh air from outside the home into your house, which means it’s significant for air to be able to flow freely to ensure appropriate and safe operation. Sometimes the intake and exhaust pipes of high efficiency units depart through the side of your home 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 meant to automatically shut off if these pipes are blocked.) To prevent air flow problems during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Take a look at the area regularly and clear any snow that has fallen into the cleared area. We realize the weather in Saint Louis can change frequently during the last few weeks of winter and that weather may impact the operation of your furnace.
