Snowstorms and Furnaces03/17/2016 Winter in Raceland isn’t finished yet. Mother Nature can certainly be unpredictable. While it can be nice one day, the next day could dump snow on us. When this occurs, you can help dodge the need for surprising furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. But, there is a difference between the two. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s vital for air to be able to transfer freely to ensure correct and safe operation. Occasionally the intake and exhaust pipes of high efficiency units leave through the side of your residence or vertically through the roof. When this is the situation, you’re susceptible to having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t panic, though. High efficiency furnaces are meant to automatically shut off if these pipes are blocked.) To stop 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 move any snow that has fallen into the cleared area. We realize the weather in Raceland can change every day during the last few weeks of winter and that weather can effect the operation of your furnace.
