Snowstorms and Furnaces03/17/2016 Winter in Keokuk isn’t done yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could dump snow on us. When this happens, you can help dodge 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 house. Nonetheless, there is a difference between these two. High-efficiency furnaces also pull fresh air from the outside into your house, which means it’s important 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 depart through the side of your residence or vertically through the roof. When this happens, you’re at risk of 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 avoid 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 remove any snow that has fallen into the cleared area. We realize the weather in Keokuk can change every day during the last few weeks of winter and that weather impacts the operation of your furnace.
