Why You Can’t Repair Your Furnace’s Heat Exchanger on Your Own

Your furnace is reliable, keeps working year after year, but eventually some parts will break down and need to be replaced. Chances are, you’ve had to call for repairs in the past more than once, but maybe you’ve also gone the DIY route here and there with smaller issues. If your heat exchanger is the problem, you absolutely cannot fix it yourself.

It’s a task you need professional furnace repair in Bossier City for, and it comes down to your safety and your family’s safety. This is why your heat exchanger is such a big deal and needs to be handled by professionals.

The Heat Exchanger Handles Carbon Monoxide

Your heat exchanger is crucial for your furnace because it handles the exhaust of carbon monoxide that’s a byproduct of the combustion process in your gas furnace. That’s the same chemical that you have a dedicated detector for in your home—because it’s that dangerous.

If your heat exchanger is cracked, carbon monoxide leaks into your home’s air supply. It can be potentially lethal, especially if it’s leaking into the air for an extended period of time. The thing is you can’t always tell that your heat exchanger is cracked.

These cracks can be so small that you can’t see them, yet they can still leak lethal amounts of carbon monoxide into your air supply. If you can actually see the crack in your heat exchanger, it’s an immediate emergency and you need to evacuate your home.

If It’s Cracked, It Requires Full Replacement

A cracked heat exchanger has no repair. It needs to be replaced. It’s a single component that needs to be wholly intact. If your technician says that you have a cracked heat exchanger, just know that it warrants full replacement. You may also have a secondary heat exchanger (if you have a condensing furnace) that may be affected, so they’ll check that as well.

Why It’s Not a DIY Project

Your furnace’s heat exchanger isn’t a simple component you can just swap out with an online tutorial. Failing to replace your heat exchanger properly can have potentially lethal implications. Without industry training, the right tools, and protocol to know that it’s installed properly, you can’t guarantee your family’s safety.

Beyond that, you also need to think about your furnace’s warranty at the same time. If you perform part replacement on your furnace, you could void whatever warranty you have. Most warranties exclusively state that repairs and maintenance need to be performed by licensed technicians in order to maintain your warranty, and you really don’t want to void that.
