Snowstorms and Furnaces03/17/2016 Winter in Denver isn’t finished yet. Mother Nature can certainly be unpredictable. While it might be nice one day, the next day could surprise us with 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 directed outside of your house. However, there is a difference between the two. 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. 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 at risk of having heavy snowfall bury them, which will obstruct 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 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 regularly and remove any snow that has fallen into the cleared area. We understand the weather in Denver can change every day during the last few weeks of winter and that weather impacts the operation of your furnace.
