In order to keep you and your family warm and cozy all winter, your heating system needs a clear path for airflow. A big snowfall can really stand in the way of the clear airflow you need—and having a high-efficiency system won’t even help. Here’s some background:
The heating system in your home has an exhaust pipe, which is sometimes called a vent pipe. Systems in newer homes have an air intake pipe, while older homes often have their vent pipe in the chimney.
Vent pipes in chimneys are not at risk of blockages caused by the snow, however air intake pipes, which reach outside through an exterior wall, do have to contend with the snow. Once snow starts to accumulate, the system’s ability to function will be drastically reduced. More importantly, blockages like these can cause safety risks for your family.
A furnace requires fuel, a spark and oxygen in order to function properly. In newer homes, furnaces rely on their air intake pipes to provide the oxygen they need to stay lit. (Older homes are less airtight and the furnace’s surroundings provide plenty of oxygen for the furnace to stay lit.)
As the furnace produces heat, it also produces exhaust, which includes carbon monoxide (CO). If a vent pipe is blocked, the CO will not be able to get out, creating a CO poisoning risk to the people inside.
Your best bet for success is to have clear intake and exhaust vents. Follow these steps to make sure that happens:
