Lots of Snow! Please be safe and be sure your furnace outside exhaust is clear of snow.
Snow accumulation around furnace vents can disrupt exhaust flow and increase the risk of dangerous carbon monoxide (CO) buildup. A blocked vent can cause a furnace to shut down or operate inefficiently, wasting energy and potentially damaging the system.
Snow Blocking a Furnace Vent Is Dangerous
Furnace vents are designed to expel combustion byproducts, including CO, safely outside the home. When snow covers or obstructs these vents, exhaust gases may back up into living spaces, posing serious health risks. Even intermittent blockages can force the furnace to work harder, increasing fuel use and wear on components. In cold climates, wind-driven snow can create ice dams at vent outlets, worsening blockages and elevating the chance of gas leaks or ignition hazards if the vent pipes overheat or distort.
