Snowstorms and Furnaces

Winter in Manassas 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 avoid the need for surprising furnace service by taking a couple precautions.

The exhaust from both conventional furnaces and high-efficiency furnaces is pushed outside of your residence. But, there is a difference between both of these. High-efficiency furnaces also take fresh air from the outside 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 home 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 meant to automatically shut off if these pipes are blocked.) To prevent air flow issues during a heavy snowfall, be sure to:

  • Confirm there’s a 3-foot/1-meter clearance surrounding your intake and exhaust pipes.
  • Take a look at the area occasionally and remove any snow that has fallen into the cleared area.
