One of the biggest issues we see during the winter are blocked furnace intakes, vents, or chimneys. There are quite a few poorly constructed or maintained buildings in Chicago. A proper furnace intake won’t be too close to the ground or blocked under a deck.
With large amounts of snow fall, improper intakes or vents can become blocked by snow or frozen by ice.
When your furnace doesn’t have proper access to new air, it can shut off completely. Another more dangerous outcome is Carbon Monoxide buildup. Generally your meter, intakes, and exhaust pipes are located on the side or back of your house. Put on some gloves and move the snow away to ensure nothing is damaged.
So when it snows outside, make sure to clear away the snow buildup and have batteries installed in your Carbon Monoxide detectors!
