Snowstorms and Furnaces03/17/2016 Winter in Phoenix isn’t finished yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could dump snow on us. When this take place, you can help dodge the need for unexpected furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your house. Nonetheless, there is a difference between these two. High-efficiency furnaces also bring 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. Sometimes the intake and exhaust pipes of high efficiency units exit through the side of your residence or vertically through the roof. When this is the situation, you’re in danger of having heavy snowfall bury them, which will block the free flow of air your high-efficiency furnace needs. (Don’t panic, though. High efficiency furnaces are meant to automatically shut off if these pipes are blocked.) To prevent air flow problems during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance near your intake and exhaust pipes. Examine the area often and move any snow that has fallen into the cleared area. We know the weather in Phoenix can change frequently during the last few weeks of winter and that weather may impact the operation of your furnace.
