Homeowners in Fort Saskatchewan use their furnace to provide heating to keep their homes warm throughout the cold Alberta winters. But the cold can cause issues with your high-efficiency furnace vents, such as freezing exhaust pipes.
If your furnace is cutting out when it’s cold, this may be due to a blockage in the intake/exhaust vent. Understanding why this may be occurring can help you manage it safely.
Why Do Furnace Exhaust Pipes Freeze in Winter?
During normal operation high-efficiency furnaces create condensation that should be drained away using a condensate system. Gasses are then vented out of the house.
But during extremely cold weather in Alberta, the moisture can freeze. If there is a blockage caused by ice/snow, this will activate the furnace’s safety mechanisms.

How Can Snow and Ice Affect Furnace Ventilation?
Snow build up, snow drifting and freezing temperatures can cause issues with your external vents.
Snow may build up around the low level vents causing a blockage. Ice may form around the exhaust.
Make sure to keep your external vents clear of snow and debris. Follow the manufacturers guidelines for the correct amount of clearance required. Never block, cover or tamper with the intake and exhaust vents.
What Should Fort Saskatchewan Homeowners Do?
If you believe your furnace is having issues with blocked or frozen vents always put your safety first.
Stand away from the external vent and see if there is any build up of snow or ice. Don’t touch any hot pipes or attempt to dismantle anything.
If your furnace has cut out make sure your thermostat is set correctly and follow the manufacturers guidelines. Don’t repeatedly reset your furnace.
Don’t use boiling water, sharp items or open flame to defrost. If you believe there is a blockage or your furnace still isn’t working contact a qualified HVAC technician.
