FAQs
What are the most common warning signs of a cracked heat exchanger in my furnace or HVAC system?
Typical indicators include a strong or unusual odor (often like formaldehyde), visible corrosion or cracks on the furnace’s metal surfaces, soot buildup inside the cabinet, rattling or banging noises after the blower turns off, persistent flu-like symptoms or headaches among occupants, and the furnace’s flame turning yellow or flickering. If you notice any of these in your Washburn home or business, shut the system off and call our certified technicians right away.
How dangerous is a cracked heat exchanger? Should I shut off my furnace immediately?
A cracked heat exchanger can allow carbon monoxide (CO) and other combustion by-products to enter the indoor air stream, posing serious health risks such as CO poisoning, respiratory irritation, and even death at high concentrations. Because of this safety hazard, we strongly recommend turning the furnace off and scheduling an emergency inspection as soon as you suspect a crack. Our Washburn team offers 24/7 emergency response to keep your household safe.
Can a cracked heat exchanger be repaired, or does it have to be replaced?
In most cases, a heat exchanger with visible cracks or holes must be replaced rather than repaired. The metal has already fatigued, and welding or patching is not considered a safe or code-compliant fix. Depending on unit age and warranty status, replacing just the heat exchanger may be possible, but on older furnaces (10–15+ years) a full system replacement is often more cost-effective. Our technician will provide side-by-side estimates so you can make an informed decision.
How do your technicians diagnose a cracked heat exchanger during a service call in Washburn?
We follow a multi-step process that includes: 1) a visual inspection with mirrors, borescopes, and high-intensity lights; 2) combustion testing for excessive CO, oxygen, and flue gas anomalies; 3) static and dynamic pressure measurements; and 4) infrared camera verification when necessary. All findings are documented with photos or video so you can clearly see any damage before authorizing repairs.
How long does it take to replace a cracked heat exchanger, and what should I expect the cost to be?
Most residential heat exchanger replacements take 4–8 hours, depending on furnace model, venting configuration, and accessibility. Costs vary widely: under manufacturer warranty you may only pay labor (typically $600–$1,000). Out-of-warranty replacements range from $1,200 to $2,400. If a full furnace replacement is more economical, expect $3,500–$6,500 for a new high-efficiency unit installed in Washburn. We provide upfront, written estimates before work begins and offer financing options.
What maintenance steps can I take to prevent future heat exchanger cracks?
1) Replace or clean air filters every 1–3 months to maintain proper airflow. 2) Schedule professional tune-ups each fall; our Washburn HVAC specialists check burner alignment, gas pressure, and heat exchanger integrity. 3) Keep supply and return vents unblocked. 4) Ensure your thermostat isn’t set excessively high, which can overheat the exchanger. 5) Install a whole-home humidifier if your house’s air is very dry—proper humidity reduces metal fatigue. Following these practices extends equipment life and keeps warranty coverage intact.
