Snowstorms and Furnaces03/17/2016 Winter in Florissant isn’t finished yet. Mother Nature can certainly be unpredictable. While it might be nice one day, the next day could dump snow on us. When this take place, you can help elude 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 home. 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 important for air to be able to flow freely to ensure proper and safe operation. Occasionally the intake and exhaust pipes of high efficiency units leave through the side of your house or vertically through the roof. When this happens, you’re in danger of having heavy snowfall bury them, which will hinder the free flow of air your high-efficiency furnace needs. (Don’t fret, 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: Confirm there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Examine the area often and clear any snow that has fallen into the cleared area. We understand the weather in Florissant can change frequently during the last few weeks of winter and that weather can effect the operation of your furnace.
