One of the last things you want to deal with as a homeowner is a furnace with a cracked heat exchanger. While this may not be the end of the world, there is a good chance that your furnace will be red-tagged (intentionally disabled until it’s repaired or replaced). If the furnace in your Greater Cleveland home does get red-tagged, it’s important to know the facts and what you might be able to do about it.
The facts about a cracked heat exchanger
The heat exchanger is a metal component within your furnace that transfers heat from the burner flame to the air before it gets distributed in your home. Due to the intense and constant heat, especially during the heavy heating season, fractures and holes can develop. If they’re serious cracks, this can create a dangerous situation in your home. This is one reason why it is advisable for you to hire an HVAC professional for regular preventative maintenance. A trained technician can determine whether the heat exchanger has a serious crack or breech and make recommendations on how to proceed, depending on the severity of the issue.
The dangers of a cracked heat exchanger
If you do have a cracked heat exchanger, and the damage is severe, you could be looking at a serious hazard to your health. Combustion fumes from the furnace will leak through the cracks and enter your home’s air. This can lead to respiratory issues, and is likely to inflame any asthma or allergy problems. Other escaping fumes may create a fire hazard and lead to carbon monoxide poisoning.
Remedies for the problem
How you proceed will depend on the severity of the issue and the condition and age of your furnace. Usually a serious crack will require a complete replacement of the part, which is an expensive proposition. A newer furnace is likely to have a warranty, and in this case, replacing a defective heat exchanger is probably the wisest course. But if you have an old or balky furnace, upgrading to a new, high-efficiency model will allow you to invest your money in a new system that will provide better home comfort and long-term energy savings.
