Snowstorms and Furnaces

March 17, 2016

Winter in Phoenix isn’t finished yet. Mother Nature can often be unpredictable. While it can be nice one day, the next day could surprise us with snow. When this take place, you can help dodge 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. But, there is a difference between these 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 correct and safe operation.

Occasionally the intake and exhaust pipes of high efficiency units depart through the side of your residence or vertically through the roof. When this is the situation, 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 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:

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