Safety and prevention are the priority in the HVAC industry and probably in your home as well. But what the pros know, the average homeowner might not. Like a cracked heat exchanger, for instance. Is it dangerous? Should you worry? Here’s the lowdown.
The American Gas Association has put in writing that their recommendation is immediate replacement when a heat exchanger is cracked. Why? Because there is the potential for carbon monoxide to leak out through the crack and into your home. Carbon monoxide, as most people well know, can be deadly. This is why it’s so highly recommended that anytime there’s a crack, the unit should be replaced.
Not every crack is created equal, and there are arguments that some cracks won’t allow carbon monoxide to leak through or that some cracks are so small that little to no air can leak through at all. The problem with those arguments is that you can never be certain that leaks will never happen.
When heat exchangers get hot, the metal expands and the cracks can open up allowing air through. Additionally, over time with use and wear-and-tear, the cracks can get worse or can spread increasing the likelihood of leaked air and a dangerous situation in your home.
When asked whether or not a cracked heat exchanger should be replaced, the answer should always be a resounding yes. There is no reason to take any kind of chance with something with the potential to be so dangerous.
If you think your heat exchanger might be cracked, or you’d like an inspection to ensure safety and prevention, contact the team at All City Heat and Air.
