Michigan Gas Utilities Reminds Customers to Clear Snow from Furnace Vents, Meters, Create Path if Possible

Monroe, MI – Recent heavy snows in some parts of our region have nearly buried natural gas meters and could have caused drifts that cover furnace vents. Customers with new high-efficiency furnaces and water heaters that vent through the wall (not into a chimney) should be wary of a buildup of snow or ice around the vent, according to Michigan Gas Utilities (MGU). The newer equipment provides great savings in terms of efficiency but a blocked vent could cause the heating system to malfunction by shutting off or, in extreme cases, lead to the accumulation of carbon monoxide in the home. MGU reminds customers to check the outside vents just to make sure they aren’t covered with snow or ice.

The recent snowfalls have increased snow cover throughout the Midwest and, coupled with windy conditions, could result in conditions that could cover vents.

The deep snow covering natural gas meters could cause the meter regulator to freeze up, disrupting the flow of gas into the home. "It’s best to clear the snow away from gas meters," said Paul Livernois, MGU spokesperson.

Wherever possible, MGU also asks that customers keep the area around their gas meters clear of snow so that the meter readers have access to them. A clear path also shows the meter readers what route you want them to take when they’re on your property. Of course, MGU does not expect customers to clear such a path if doing so is physically difficult or could aggravate medical problems. Livernois also said that conditions are "just about perfect” for the formation of large icicles as snow on rooftops melts due to the radiant heat of the sun at this time of year and below freezing temperatures.

"Icicles that form above natural gas meters could break and fall onto the meters causing damage," he said. "Damaged meters could malfunction and cause service interruptions to homes. It's a good idea to clear the area above meters, if you can do it safely."
