Furnaces use mechanical parts to operate, and mechanical parts eventually will start to wear down and require repairs. No matter how well you take care of your furnace, at some point you will likely need to call for professionals to fix it.
However, one of the most important repairs that a furnace can need is not to a mechanical part like a fan or a motor. It’s a repair that replaces the heat exchanger, a clamshell-shaped chamber that performs the crucial part of the heating cycle that safely moves the heat of combustion gas to the air that will enter your home. We are going to share with you the basics of the heat exchanger and why repairs are so important when something goes wrong with it.

The Heat Exchanger
Combustion gas enters a furnace’s heat exchanger, where it raises the temperature of the exchanger walls and then transfers that heat to air blown around the exchanger. After the gas cools down, it exits the heat exchanger and leaves the house through an exhaust flue.
If a heat exchanger begins to corrode (which occurs because of a reaction with the combustion gas) the force of it expanding each time it heats up can lead to cracks. This is a potentially hazardous situation because these cracks lead to the escape of the exhaust fumes—toxic carbon monoxide—into the cabinet and possibly into your home.
How can you tell your heat exchanger is cracked? There are a few warnings signs. If you notice corrosion developing anywhere on your furnace, call for repairs. Have carbon monoxide detectors installed in your home, and should they warn of a spike in CO, call for repairs. If you hear a loud clicking noise from the furnace before the blower fan comes on, call for repairs. Don’t let unusual noises from your heating system go without a call to professionals.
Do Not Attempt Repairs on Your Own
It’s risky to try to make amateur repairs to a natural gas-powered furnace. You should never tamper with anything connected to a main gas line unless you have the training and tools for it. Work with a heat exchanger needs a licensed, trained professional. Shut off the gas power to your furnace and give a heating technician a call immediately.
