Snowstorms and Furnaces03/17/2016 Winter in Carlsbad isn’t finished yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could change to snow. When this happens, you can help dodge the need for unforeseen furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your house. But, there is a difference between both of these. High-efficiency furnaces also take fresh air from outside the home into your house, which means it’s significant for air to be able to transfer freely to ensure appropriate and safe operation. Once in a while the intake and exhaust pipes of high efficiency units leave through the side of your residence or vertically through the roof. When this is the case, 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 worry, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To avoid 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. Look at the area often and remove any snow that has fallen into the cleared area.
