Snowstorms and Furnaces

Winter in McHenry isn’t finished yet. Mother Nature can often be unpredictable. While it could be nice one day, the next day could dump snow on us. When this happens, you can help dodge the need for unexpected furnace service by taking a couple precautions.

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

Once in a while 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 case, you’re susceptible to 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 meant to automatically shut off if these pipes are blocked.) To avoid air flow issues during a heavy snowfall, be sure to:

  • Make sure there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes.
  • Examine the area often and move any snow that has fallen into the cleared area.

We know the weather in McHenry can change frequently during the last few weeks of winter and that weather may impact the operation of your furnace.
