Snowstorms and Furnaces03/17/2016 Winter in Robstown isn’t quite over 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 avoid the need for surprising furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your home. Nonetheless, 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 move freely to ensure correct and safe operation. Occasionally the intake and exhaust pipes of high efficiency units leave through the side of your residence or vertically through the roof. When this happens, you’re susceptible to having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t worry, though. High efficiency furnaces are meant 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 surrounding your intake and exhaust pipes. Take a look at the area often and clear any snow that has fallen into the cleared area. We realize the weather in Robstown can change on a daily basis during the last few weeks of winter and that weather can effect the operation of your furnace.
