Snowstorms and Furnaces03/17/2016 Winter in the Upper Rio Grande Valley 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 happens, you can help avoid the need for surprising furnace service by taking certain precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your home. 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 vital for air to be able to flow freely to ensure proper and safe operation. Once in a while the intake and exhaust pipes of high efficiency units exit through the side of your residence or vertically through the roof. When this is the situation, you’re at risk of 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 surrounding your intake and exhaust pipes. Examine the area occasionally and move any snow that has fallen into the cleared area. We understand the weather in the Upper Rio Grande Valley can change every day during the last few weeks of winter and that weather may impact the operation of your furnace.
