Snowstorms and Furnaces03/17/2016 Winter in Portland Metro isn’t done yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could surprise us with snow. When this happens, you can help avoid 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 home. However, there is a difference between both of these. High-efficiency furnaces also bring fresh air from outside the home 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 residence or vertically through the roof. When this happens, you’re at risk of having heavy snowfall bury them, which will block 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 avoid air flow problems during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Examine the area occasionally and remove any snow that has fallen into the cleared area. We understand the weather in Portland Metro can change every day during the last few weeks of winter and that weather impacts the operation of your furnace.
