Cold weather is fast approaching, and the last thing you want is for your furnace to break down on the first truly frigid day. Could your equipment be on the fritz? Keep an eye out for the following warning signs and red flags:

Old age

Furnaces that are more than 15 years old may need to be replaced. To figure out just how old your unit is, refer to the owner’s manual or call up the manufacturer and be ready to provide the model number.

Frequent repairs

Increased utility costs

Don’t blame higher-than-usual gas and electric bills on rising prices alone. A poorly maintained furnace can become less efficient over time, driving up operating costs.

Yellow burner flame

The flame within your gas-burning furnace should be blue, not yellow. Discoloration could indicate a presence of carbon monoxide — a poisonous and potentially lethal gas.
