4 Telltale Signs Your Heat Exchanger Is Cracked in Your Leland Home

Cracked or broken heat exchangers contribute to approximately 1,500 deaths annually in the United States, according to Hunker.com. These exchangers, which enhance indoor heat circulation, require expert maintenance and repair. Here are four significant signs of a broken heat exchanger in your Leland, NC, home.

1. Yellow Furnace Flame

Usually, the furnace produces a steady blue flame, without any flickering. A flickering yellow flame is among the visible signs of a broken heat exchanger. The yellow flame could also be due to the buildup of dirt in the burner.

2. Soot Accumulation

Cracked heat exchangers exhibit soot accumulation on the interior surface of the furnace. Among the leading reasons for soot buildup is incomplete combustion in the burner. Consequently, excess carbon accumulates in the furnace, causing a layer of black soot.

Cracks within the heat exchanger can also cause your furnace to produce a dirty flame. Thus, you’re likely to notice a soot layer within the furnace. Make sure to call an HVAC specialist for repairs if you notice any soot in your furnace.

3. Unpleasant Odor

The emission of bad odor from the HVAC unit could be due to a crack in the heat exchanger. This pungent odor is similar to that of formaldehyde.

Inhaling the foul smell is highly detrimental to your respiratory system. You may experience persistent headaches and respiratory illnesses. If you notice any bad smell coming from your system, seek a professional HVAC contractor.

4. Corrosion

Corrosion on the furnace’s external surface is another notable sign of a cracked heat exchanger. Corrosion on the exterior components indicates that the internal parts are wearing similarly. Notable signs of possible wear on the furnace include rust and stress cracks.

Among the common causes of rusting is exposure to moisture. Chloride fumes also contribute to immense corrosion of the furnace components.
