Snowstorms and Furnaces03/17/2016 Winter in Huntsville isn’t finished yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could dump snow on us. When this take place, you can help avoid the need for unforeseen 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 these two. 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. Occasionally the intake and exhaust pipes of high efficiency units exit through the side of your house or vertically through the roof. When this happens, you’re susceptible to 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 stop 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. Take a look at the area occasionally and move any snow that has fallen into the cleared area. We understand the weather in Huntsville can change on a daily basis during the last few weeks of winter and that weather impacts the operation of your furnace.
