Having a fractured heat exchanger isn't a good situation. The fact is that, many homeowners don’t understand specifically what this entails. If you want to maintain your furnace in your home, it is essential that you are aware of 3 things:
Understand how a cracked heat exchanger develops
Your furnace’s heat exchanger is actually a piece of metal that shields the air stream leaving your furnace from the fire which it creates. This metal is subjected to intense heat, often for long durations. This continuous exposure wears down the heat exchanger and can cause hair line cracks and holes to appear within the metal.
Recognize the visible difference between shallow and major cracks
Not all cracks will mean the end of your furnace. It's a wise decision to have an HVAC specialist check out your furnace and check for any cracks. If the damage is superficial, there may be no reason to replace either the heat exchanger or entire system. If the damage is significant, however, the furnace is going to be considered dangerous to run as combustion materials can easily leak through the breaks and create a health risk to your family, sometimes resulting in significant respiratory issues and even deadly carbon monoxide poisoning.
Recognize the chance of your furnace being red-tagged
The HVAC tech will examine your furnace for any likely damages. If he discovers that there is a cracked heat exchanger which is substantial enough, your furnace is going to be “red-tagged.” Because of this you won't be permitted to operate your furnace until either it's either repaired or replaced. Based on the seriousness of the damage, you might be able to replace the heat exchanger itself, which is often an expensive fix. Regardless of the higher cost of a full furnace replacement, this is often the better option ultimately.
