Snowstorms and Furnaces

March 17, 2016

Winter in Hattiesburg isn’t quite over yet. Mother Nature can often be unpredictable. While it might be nice one day, the next day could dump snow on us. When this take place, you can help elude the need for unforeseen furnace service by taking a couple precautions.

The exhaust from both conventional furnaces and high-efficiency furnaces is moved outside of your house. However, there is a difference between these two. High-efficiency furnaces also pull fresh air from the outdoors into your house, which means it’s vital for air to be able to transfer freely to ensure proper and safe operation.

Occasionally the intake and exhaust pipes of high efficiency units leave 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 block the free flow of air your high-efficiency furnace needs. (Don’t panic, 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 around your intake and exhaust pipes.
  • Examine the area regularly and remove any snow that has fallen into the cleared area.
