Snowstorms and Furnaces03/17/2016 Winter in San Angelo isn’t done yet. Mother Nature can certainly be unpredictable. While it might 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 certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your home. But, 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 move freely to ensure appropriate and safe operation. Occasionally the intake and exhaust pipes of high efficiency units depart through the side of your house or vertically through the roof. When this happens, you’re susceptible to having heavy snowfall bury them, which will obstruct 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 avoid air flow problems during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Take a look at the area often and remove any snow that has fallen into the cleared area. We understand the weather in San Angelo can change every day during the last few weeks of winter and that weather can effect the operation of your furnace.
