Snowstorms and Furnaces03/17/2016 Winter in Macon isn’t finished yet. Mother Nature can certainly be unpredictable. While it can be nice one day, the next day could change to snow. When this occurs, you can help elude the need for unforeseen furnace service by taking a couple precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your residence. But, there is a difference between both of these. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s vital 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 home or vertically through the roof. When this is the case, you’re at risk 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 planned to automatically shut off if these pipes are blocked.) To stop air flow obstruction 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 regularly and clear any snow that has fallen into the cleared area. We realize the weather in Macon can change every day during the last few weeks of winter and that weather may impact the operation of your furnace.
