Snowstorms and Furnaces03/17/2016 Winter in Lexington isn’t done 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 elude the need for unexpected 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 both of these. High-efficiency furnaces also pull fresh air from the outside into your house, which means it’s important for air to be able to move freely to ensure appropriate 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 at risk of having heavy snowfall bury them, which will hinder the free flow of air your high-efficiency furnace needs. (Don’t fret, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To prevent air flow problems during a heavy snowfall, be sure to: Make sure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Examine the area regularly and clear any snow that has fallen into the cleared area. We understand the weather in Lexington can change frequently during the last few weeks of winter and that weather can effect the operation of your furnace.
