Cracked Heat Exchanger Scam

Your furnace’s heat exchanger is not easily accessible, it cannot be repaired, it is an expensive part to replace and oftentimes requires an entire furnace replacement, so this is a popular scam among dishonest HVAC technicians. Below is more information about heat exchangers, how they become cracked, and the signs of a cracked heat exchanger.

If you are told your heat exchanger is cracked, we always recommend getting a second opinion from another company!

What is a heat exchanger?

The heat exchanger is a thin metal piece between the combustion chamber and the blower. As the combustion chamber heats the exchanger, air is blown across the surface which heats the air. The warm air is then sent through your home’s ductwork to warm your home.

How does a heat exchanger crack?

Metal expands when it heats up and contracts when it cools down. Over time, this makes the metal more fragile which could lead to the metal cracking or breaking. The heat exchanger will typically last 15 years or more, but if your furnace is very old or poorly maintained, the chances of the heat exchanger cracking is higher than normal.

What are the signs of a cracked heat exchanger?

When the heat exchanger cracks, the most common problem is carbon monoxide leaking into your unit and throughout your home. You should have carbon monoxide detectors that will tell you if there is a leak, but if the leak is very small, you may notice your pilot light is discolored. Other signs include excess condensation coming from your unit, a strong odor, or a buildup of discolored soot.

Am I getting scammed?

If your furnace is fairly new and an HVAC technician tells you your furnace’s heat exchanger is cracked and the unit is no longer under warranty, this may be a scam. If your furnace is over 10 years old, it is a bit more likely that your heat exchanger is cracked. We always recommend keeping an eye out for the signs above and getting second opinion, regardless of the age of your unit.
