Snowstorms and Furnaces03/17/2016 Winter in Humble isn’t finished yet. Mother Nature can typically be unpredictable. While it might be nice one day, the next day could surprise us with snow. When this occurs, you can help avoid the need for unforeseen furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your house. However, there is a difference between both of these. High-efficiency furnaces also bring fresh air from the outside into your house, which means it’s significant 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 is the situation, 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 worry, though. High efficiency furnaces are designed to automatically shut off if these pipes are blocked.) To avoid air flow problems during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Take a look at the area often and move any snow that has fallen into the cleared area. We realize the weather in Humble can change on a daily basis during the last few weeks of winter and that weather impacts the operation of your furnace.
