Don’t dismiss your suspicions if you suspect a fractured heat exchanger in your gas furnace. If not fixed promptly, a damaged heat exchanger might be dangerous to your family. Toxic gases like carbon monoxide will be released. Many deaths are caused by cracked heat exchangers and carbon monoxide poisoning worldwide. Regularly inspecting and maintaining the HVAC system is essential to keep your family safe.
What Causes Heat Exchangers to Fail?
A dirty, blocked air filter is one of the most prevalent causes of heat exchanger failure. Overheating and an oversized furnace can also cause heat exchanger cracking. However, ordinary wear and slash is the most typical cause of heat exchanger cracking. Metal heat exchangers undergo continual expansion and contraction, which will merely cause the metal to fatigue and shatter over time.
Symptoms of a Broken Heat Exchanger in Your Furnace:
A faulty heat exchanger will frequently emit an unpleasant and pungent stench that smells like formaldehyde. When inhaled, the vapors are incredibly hazardous to your health. You’ll expose yourself to further injury or danger if you neglect the problem.
When your heating system has a lot of carbon or the fuel doesn’t burn thoroughly, the furnace will produce a lot of soot. On the other hand, a damaged heating exchanger could cause increased soot formation in the heating system. It is advised to take professional help like furnace service Dallas.
Cracks and Corrosion
Call a skilled technician like furnace repair Dallas, TX right away if you see corrosion or cracks in other parts of your furnace, such as the draught diverter box or inducer motor.
The Appearance of the Flame
The flame that heats your air can be blue, which is normal, but orange or yellow are not. A yellow flame could indicate that your burner is unclean or that your heat exchanger has fractured.
If your heat exchanger is fractured, you’ll hear a rattling noise when your thermostat turns on the heat. As the heat exchanger heats up, cracks expand and shrink, resulting in rattling, popping, or pounding noises.
Presence of Carbon Monoxide
Carbon monoxide (CO) is a poisonous flammable gas with no odor, color, or taste. A faulty heat exchanger could cause CO to leak into your home. Relying on a CO alarm to identify a broken heat exchanger is not recommended; instead, furnace replacement companies in Dallas propose a yearly assessment of your furnace and heating system.
Water collection on the floor around the furnace
If your furnace is attached to a whole-house humidifier, it could leak, and internal drainage systems could become clogged. To figure out what’s causing the problem, you’ll need to hire a skilled HVAC contractor.
What Are Your Options?
If your heat exchanger fails, you have two choices: replace the heat exchanger or replace the furnace. Additional parts and controls in the furnace will very certainly need to be changed at this time.
