Snowstorms and Furnaces03/17/2016 Winter in Tuscaloosa isn’t quite over yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could change to snow. When this take place, you can help avoid the need for unexpected furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your house. However, there is a difference between both of these. High-efficiency furnaces also take fresh air from the outdoors into your house, which means it’s significant 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 depart through the side of your home or vertically through the roof. When this is the situation, 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 fret, though. High efficiency furnaces are meant to automatically shut off if these pipes are blocked.) To prevent air flow problems during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Take a look at the area regularly and remove any snow that has fallen into the cleared area.
