Snowstorms and Furnaces03/17/2016 Winter in Cedar Rapids isn’t quite over yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could dump snow on us. When this take place, you can help dodge the need for unexpected furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your house. But, there is a difference between the two. High-efficiency furnaces also take fresh air from the outdoors into your house, which means it’s vital for air to be able to flow freely to ensure correct and safe operation. Once in a while 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 case, you’re in danger of 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 designed to automatically shut off if these pipes are blocked.) To stop air flow issues during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Take a look at the area occasionally and clear any snow that has fallen into the cleared area. We understand the weather in Cedar Rapids can change frequently during the last few weeks of winter and that weather may impact the operation of your furnace.
