Snowstorms and Furnaces

Winter in Mankato area isn’t finished yet. Mother Nature can certainly be unpredictable. While it can be nice one day, the next day could dump snow on us. When this occurs, you can help dodge 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 house. However, there is a difference between the two. High-efficiency furnaces also take fresh air from the outside into your house, which means it’s important for air to be able to transfer freely to ensure correct 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 is the case, 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 planned to automatically shut off if these pipes are blocked.) To avoid air flow problems during a heavy snowfall, be sure to:

  • Make sure there’s a 3-foot/1-meter clearance near your intake and exhaust pipes.
  • Look at the area occasionally and remove any snow that has fallen into the cleared area.
