The metal shells and tubes of heat exchangers transfer heat from one place to another. An exhaust/combustion by-product (also known as flue gas) enters and travels through a heat exchanger when a furnace burns natural gas or propane fuel. As the hot flue gas exits the furnace, it heats the metal. As this occurs, the hot metal heats the air circulating over the exterior of the heat exchanger.

When has your furnace failed to produce enough heat for you? You probably called a technician to check it out. When the technicians determine what is wrong with your furnace, they tell you that the heat exchanger needs to be replaced.
What exactly does a heat exchanger do? It is important to note that your HVAC equipment is not responsible for producing cool energy. HVAC systems work by transferring heat (thermal energy) from one area to another. That is exactly what a heat exchanger does: it moves thermal energy from one place to another. Therefore, when it is hot outside, your HVAC system and its heat exchanger are responsible for removing thermal energy from your home and storing it when it is cold outside.
