FAQs
What warning signs indicate that my furnace’s heat exchanger may be cracked?
Homeowners in Tracy City often first notice a persistent sulfur-or gas-like odor, visible rust or corrosion inside the furnace cabinet, or hear unusual rattling and popping sounds after the burner cycles off. Other clues include unexplained soot around the burner compartment, water pooling at the base of the unit, and frequent or unexplained activation of a carbon-monoxide (CO) alarm. If you experience headaches, nausea, or flu-like symptoms while the heat is running, shut the system off immediately and call for professional service, as CO leakage is a serious health risk.
Is it safe to keep running my heater if a technician suspects the heat exchanger is cracked?
No. A cracked heat exchanger can allow flue gases—especially carbon monoxide—to mix with the air that is circulated through your ducts. Because CO is colorless and odorless, you might not realize you’re being exposed. For safety, national mechanical codes and most furnace manufacturers require the appliance to be shut down until repairs are made. Our Tracy City technicians will tag the unit "unsafe to operate," turn off the gas supply, and explain your repair or replacement options on the spot.
How do you confirm a cracked heat exchanger during a service call in Tracy City?
Our NATE-certified technicians perform a multi-step diagnosis. We start with a combustion analysis to check for abnormal CO levels in the flue. Next, we visually inspect the exchanger with an illuminated mirror and borescope camera, allowing us to see fissures, pinholes, or rusted seams without dismantling the entire furnace. We document findings with photos or video and provide you with a written report that meets Tennessee code requirements and most manufacturer warranty guidelines.
Can a cracked heat exchanger be repaired, or does the whole furnace need to be replaced?
Most heat exchanger cracks are not safely weldable because the metal has fatigued from years of expansion and contraction. For furnaces under 10 years old that are still within the manufacturer’s heat-exchanger warranty, we can often order and install a replacement exchanger, restoring the furnace at a fraction of the cost of a new unit. If the furnace is older, out of warranty, or has additional issues such as a failed blower motor or obsolete controls, a full replacement usually offers better long-term value and energy savings.
How long will I be without heat while the exchanger is replaced, and what are the typical costs?
In most Tracy City homes, a single-stage gas furnace heat exchanger can be replaced in 4–6 labor hours, so you’re typically without heat for part of one day. We stock common exchanger models, but if we need to special-order one, shipping from the manufacturer usually adds 2–5 business days. Labor and parts combined can range from $900 to $2,000, depending on furnace size and brand—though the part itself may be covered by a limited lifetime warranty. We offer space heaters at no charge and 0% financing to keep you comfortable during the interim.
How can I prevent heat exchanger cracks in the future?
The leading causes of exchanger failure are restricted airflow, overheating, and poor combustion. Change or clean furnace filters every 1–3 months, keep supply and return vents unblocked, and schedule professional maintenance each fall. Our annual tune-up includes blower cleaning, burner adjustment, and verification of proper temperature-rise so the furnace runs within manufacturer specifications. Installing a whole-house humidifier can also help by reducing metal fatigue caused by excessively dry air common during Tracy City winters.
