Is a Cracked Heat Exchanger Really That Big of a Deal?

If you use a furnace to provide heat for your home here in Beaumont, the phrase “cracked heat exchanger” is probably one you never want to hear. A cracked heat exchanger is indeed a big problem for your home. Gas furnaces are the most common type of the furnace system across the country. While these systems are far from being inherently dangerous, any natural gas-powered appliance has the chance to develop potential safety hazards, and a cracked heat exchanger is one of the leading ways for your home to allow toxic gas into your space. If you have a furnace in your Beaumont, TX home then make sure you understand this potential hazard. If you’re currently experiencing this problem and need quality service to rectify the issue, contact our team.

So What’s a Heat Exchanger?

Chances are that you don’t spend your free time brushing up relevant HVAC terminology. We don’t expect you to, but it is important to understand if you want to keep your home safe. So here’s what you need to know, your heat exchanger is what allows you to heat up the air that travels through your ventilation system. Your furnace’s burners generate hot combustion gas and this gas collects inside the heat exchanger. The gas then heats up the metal walls of your heat exchanger and when the blower comes on, air is sent around the heat exchanger picking up the heat in the process and then blowing it through your ducts. This is an important part of your furnace system, without it, you can’t heat your home safely.

What Are the Dangers of a Cracked Heat Exchanger?

Since your heat exchanger is metal, it incurs wear and tear through the process of heating and cooling. Over time, the stress can eventually become strong enough to cause cracking. Another common problem is corrosion caused by the reaction of gas and metal and improper venting. Even if the cracks start off small or if there’s minor corrosion, there’s enough cracking to allow harmful gasses to leak into your home.

Signs You Have a Problem

It’s unlikely that you’re looking at the inner workings of your furnace system every day, so how can you know if you have a crack heat exchanger? Here are a few signs:

  • A Clicking Noise: Have you noticed that your furnace makes a clicking noise after the fan stops blowing? This is a sign of a cracked heat exchanger, so have it looked at by a professional as soon as possible.
  • Bad Smells: If you notice that there’s an odd smell in your home during or after your heater runs, make sure you contact a professional team.
  • Physical Signs: If your family members are experiencing frequent headaches or flu-like symptoms for extended periods of time, this could likely be the side effect of a cracked heat exchanger making you sick. Leaking gases cause these symptoms along with eye irritation, sleepiness, disorientation, and nausea.
  • Soot: Notice that there’s soot on the inside of your furnace? This is a sign of black carbon build up and a sign that your furnace isn’t burning cleanly because of incomplete combustion likely due to a crack.
