Snowstorms and Furnaces03/17/2016 Winter in Ballwin isn’t done yet. Mother Nature can certainly be unpredictable. While it could be nice one day, the next day could surprise us with 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 moved outside of your home. But, there is a difference between the two. High-efficiency furnaces also bring fresh air from outside the home into your house, which means it’s vital for air to be able to transfer freely to ensure correct and safe operation. Once in a while the intake and exhaust pipes of high efficiency units depart through the side of your house or vertically through the roof. When this happens, you’re susceptible to having heavy snowfall bury them, which will hinder the free flow of air your high-efficiency furnace needs. (Don’t worry, though. High efficiency furnaces are meant 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 occasionally and clear any snow that has fallen into the cleared area.
