Snowstorms and Furnaces03/17/2016 Winter in Midlothian isn’t done yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could change to snow. When this take place, you can help avoid the need for unexpected furnace service by taking some precautions. The exhaust from both conventional furnaces and high-efficiency furnaces is directed outside of your house. However, there is a difference between the two. High-efficiency furnaces also bring fresh air from outside the home into your house, which means it’s vital for air to be able to flow freely to ensure proper and safe operation. Occasionally the intake and exhaust pipes of high efficiency units leave through the side of your house or vertically through the roof. When this happens, you’re in danger 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 planned to automatically shut off if these pipes are blocked.) To prevent air flow issues during a heavy snowfall, be sure to: Ensure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes. Look at the area occasionally and remove any snow that has fallen into the cleared area. We understand the weather in Midlothian can change every day during the last few weeks of winter and that weather may impact the operation of your furnace.
