Various factors could necessitate a furnace replacement in Edmonton. Top among them is a defective heat exchanger. A heat exchanger is the metal chamber that separates the air you breathe from the furnace’s combustion process. This component heats the air that gets blown across its heated surface. It is after this step that the air gets distributed to warm your home. A tight seal is always present in a functional heat exchanger to separate the air as indicated above because some of the gasses present such as carbon monoxide are lethal. Let’s discuss some of the causes of heat exchanger failure and the steps you should take. Temperature Changes The thin metal section of the heat exchanger experiences constant expansion and contraction as the temperatures rise and fall respectively. Note that such changes are inevitable due to their importance in the home heating process.
