Snowstorms and Furnaces03/17/2016 Winter in Pacheco isn’t finished yet. Mother Nature can certainly 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 unforeseen furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your residence. Nonetheless, there is a difference between these two. High-efficiency furnaces also bring fresh air from outside the home into your house, which means it’s important for air to be able to move freely to ensure correct 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 is the case, you’re at risk 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 avoid air flow obstruction during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Examine the area occasionally and remove any snow that has fallen into the cleared area.
