5 Signs of a Cracked Furnace Heat Exchanger in Henrico, VA

Your furnace’s heat exchanger warms the air that is then distributed around your home. Combustion gasses collect there during the heating process before being safely released outside. These four signs could indicate you have a cracked heat exchanger in Henrico, VA.

1. Different Furnace Flame Color

When your furnace is functioning properly, it has a constant blue flame. If you notice flickering or an odd color, something is likely malfunctioning inside your furnace. While a yellow flame can just mean the sensor is dirty, it may also mean you have a damaged heat exchanger.

2. Unpleasant Odor

Regularly check your furnace for a strong, unpleasant odor that’s similar to formaldehyde. This odor can be deadly when inhaled and usually causes severe headaches. It’s essential to call an HVAC technician for repairs as soon as possible to stop the fumes from spreading.

3. Presence of Soot

Soot occurs when there’s a lot of carbon in your heating system. This happens during incomplete combustion when your furnace can’t efficiently burn all of its fuel. The two most common causes are dirty burners or a compromised heat exchanger.

4. Water Around Furnace

A functioning furnace won’t suffer from any condensation issues. However, a cracked heat exchanger can lead to water accumulating around the base of your furnace. A professional will be able to pinpoint the issue and minimize the overall damage.

5. External Corrosion or Cracks

Furnaces begin to show signs of wear and tear the more they’re used over the years. If you’re seeing cracks, corrosion, and other external damage, it’s likely some of the internal components have worn out as well.
