The outside vents for your furnace are most often placed either on your roof or on the side of your home above the exposed foundation wall. Both places have the potential for getting snowed-in during heavy winter snows. It’s important to keep them clear of snow so they can vent properly. Even if the snow isn’t that deep, winds can blow the snow into higher drifts. When a vent is buried in snow it can’t get the air it needs. The furnace won’t be able to come on, although it will continually try. It won’t take long for the temperature in your home to drop from lack of heat. If that happens to you, call Summers & Zim’s at 610-593-5129 immediately to get your vents cleared and your heat back on.
