Diagnosing a Cracked Furnace Heat Exchanger in Hartwell, GA

Fixing Furnace Heat Exchanger

Your furnace’s heat exchanger securely contains the combustion gasses used to heat your home. As this component ages, it can develop cracks and wear that impact its efficiency and can affect your safety. Keep reading for some common signs of a damaged furnace heat exchanger in Hartwell, GA.

Yellow Furnace Flame

Your furnace flame should burn steadily and be blue, but a yellow flame could mean an inefficiency issue with your burner or heat exchanger. If the flame is off-color or flickering, there may be serious damage that needs immediate furnace repairs.

Presence of Soot

Gas furnaces produce soot when there’s a substantial amount of carbon in the system. This occurs when your furnace isn’t efficiently burning all of its fuel, otherwise referred to as incomplete combustion. While this issue can result from a defective burner, it’s can also be caused by a damaged furnace heat exchanger.

Unpleasant Odor

If you notice what smells like formaldehyde near your furnace, immediately leave the area and call an HVAC service technician. Compromised heat exchangers leak toxic gasses into the air that can cause headaches, dizziness and nausea. The longer you’re exposed to these fumes, the more your health could be at risk.

Visible Rust or Corrosion

Many furnaces develop exterior rust and corrosion over time, which can become an issue when it spreads up into the interior of your furnace. Once your furnace heat exchanger rusts, it may develop cracks and no longer be able to safely heat your home throughout winter.
