Snowstorms and Furnaces03/17/2016 Winter in Shelby Township isn’t finished yet. Mother Nature can certainly be unpredictable. While it can be nice one day, the next day could change to snow. When this occurs, you can help avoid the need for surprising furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. But, there is a difference between both of these. High-efficiency furnaces also take fresh air from outside the home into your house, which means it’s vital for air to be able to move freely to ensure appropriate and safe operation. Once in a while 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 panic, 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 near your intake and exhaust pipes. Examine the area occasionally and clear any snow that has fallen into the cleared area. We realize the weather in Shelby Township can change every day during the last few weeks of winter and that weather may impact the operation of your furnace.
