In cold climate, delaying repairs can make indoor temperatures drop quickly, creating an uncomfortable and probably harmful situation.
Strange noises coming from the furnace are another warning sign that ought to by no means be ignored. While furnaces naturally make some sound throughout operation, loud banging, screeching, rattling, grinding, or booming noises often point out mechanical trouble.
