Snowstorms and Furnaces03/17/2016 Winter in Vancouver isn’t done yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could change to snow. When this happens, you can help dodge the need for unforeseen furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your house. However, there is a difference between these two. High-efficiency furnaces also take fresh air from outside the home into your house, which means it’s vital for air to be able to transfer freely to ensure correct and safe operation. Once in a while the intake and exhaust pipes of high efficiency units exit through the side of your residence or vertically through the roof. When this happens, you’re in danger of having heavy snowfall bury them, which will obstruct 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 issues during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Look at the area often and move any snow that has fallen into the cleared area. We realize the weather in Vancouver can change on a daily basis during the last few weeks of winter and that weather may impact the operation of your furnace.
