Snowstorms and Furnaces03/17/2016 Winter in Rock Hill isn’t quite over yet. Mother Nature can certainly be unpredictable. While it could be nice one day, the next day could surprise us with snow. When this take place, you can help dodge the need for unexpected furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your home. But, there is a difference between these two. High-efficiency furnaces also bring fresh air from the outside into your house, which means it’s significant for air to be able to flow freely to ensure appropriate and safe operation. Occasionally the intake and exhaust pipes of high efficiency units depart through the side of your home or vertically through the roof. When this happens, 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 issues during a heavy snowfall, be sure to: Confirm there’s a 3-foot/1-meter clearance around your intake and exhaust pipes. Examine the area often and move any snow that has fallen into the cleared area. We understand the weather in Rock Hill can change on a daily basis during the last few weeks of winter and that weather may impact the operation of your furnace.
