Snowstorms and Furnaces03/17/2016 Winter in Dallas isn’t finished yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could dump snow on us. When this happens, you can help elude the need for surprising furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your house. Nonetheless, there is a difference between the 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 transfer freely to ensure proper and safe operation. Sometimes the intake and exhaust pipes of high efficiency units depart through the side of your home or vertically through the roof. When this is the situation, you’re susceptible to having heavy snowfall bury them, which will obstruct 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 issues during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance around 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 Dallas can change on a daily basis during the last few weeks of winter and that weather may impact the operation of your furnace.
