FAQs
Why is a cracked heat exchanger considered dangerous for my Collegedale home?
When a heat exchanger develops cracks, combustion gases—especially carbon monoxide—can leak into the supply air that circulates through your ductwork. Carbon monoxide is odorless and colorless, but even small amounts can cause headaches, nausea, and, at higher concentrations, serious illness or death. A cracked heat exchanger also reduces furnace efficiency and can damage other components. Because of these safety and performance risks, industry codes require that a furnace with a cracked heat exchanger be shut down until it is repaired or replaced.
What symptoms should I look for that might indicate my heat exchanger is cracked?
Common warning signs include: • A persistent metallic or chemical smell when the furnace is running. • Soot, corrosion, or rust around the burner compartment. • Unexplained activation of carbon-monoxide alarms. • Visible cracks, holes, or warping on the exchanger surface (often found during an inspection). • Flame behavior changes—such as flames that flutter or turn yellow. • Frequent system cycling, higher utility bills, or uneven heating throughout your Collegedale home. Because these symptoms can overlap with other HVAC problems, a professional inspection is the only reliable way to confirm a cracked heat exchanger.
Can a cracked heat exchanger be repaired, or must the entire unit be replaced?
In most cases, manufacturers, building codes, and insurance carriers do not permit field repairs of cracked heat exchangers. Welding or sealing the crack may provide only a temporary fix and can void furnace warranties. Typically, once a crack is confirmed, the exchanger—or the entire furnace if the part is unavailable or the system is aging—is replaced. Our Collegedale service team will review the furnace’s age, warranty coverage, and efficiency before recommending the most cost-effective option.
What should I do immediately if I suspect my heat exchanger is cracked?
1. Turn off the furnace at the thermostat and at the main power switch. 2. Ventilate the home by opening windows and doors. 3. Evacuate if carbon-monoxide alarms are sounding or if anyone feels dizzy, nauseated, or light-headed. 4. Call 911 if symptoms of CO poisoning are present. 5. Contact our 24/7 heat-repair line. We prioritize cracked heat exchanger calls in Collegedale and can usually have a certified technician on site the same day to perform a combustion analysis and camera inspection.
How can I prevent future heat-exchanger cracks?
• Schedule annual furnace maintenance so technicians can clean burners, check airflow, and inspect the exchanger for early signs of stress. • Replace air filters every one to three months; restricted airflow causes the exchanger to overheat. • Keep supply and return vents unblocked to maintain proper air balance. • Ensure the gas pressure and burner flames are set correctly, eliminating hot spots. • Consider installing a high-quality thermostat with fan-delay settings that allow heat to dissipate after the burners shut off. • If your furnace is over 15 years old, plan for proactive replacement with a modern, high-efficiency model designed to run cooler and last longer.
How fast can Collegedale Heating & Air repair a cracked heat exchanger, and what does the process involve?
We offer same-day emergency service within Collegedale city limits and most surrounding neighborhoods. After diagnostic confirmation, we present a written estimate. If the heat exchanger is covered by manufacturer warranty, you pay only labor; otherwise, we stock common furnace models in our warehouse. A typical exchanger replacement takes 4–6 hours, including disassembly, part replacement, reassembly, and a full safety test with combustion analysis and CO monitoring. If a full furnace replacement is recommended, we can often install a new unit the next business day and haul away the old equipment at no charge.
