Snowstorms and Furnaces03/17/2016 Winter in Madera isn’t quite over yet. Mother Nature can certainly be unpredictable. While it could be nice one day, the next day could surprise us with snow. When this happens, you can help dodge the need for surprising furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your residence. However, there is a difference between the two. High-efficiency furnaces also take fresh air from the outdoors into your house, which means it’s important for air to be able to flow freely to ensure proper 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 hinder the free flow of air your high-efficiency furnace needs. (Don’t panic, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To prevent air flow obstruction during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Look at the area often and clear any snow that has fallen into the cleared area. We realize the weather in Madera can change frequently during the last few weeks of winter and that weather impacts the operation of your furnace.
