Our technicians start by diagnosing your furnace to confirm the flame sensor is the root cause of the problem. We check for other potential issues like faulty wiring, gas supply problems, or dirty burners that could cause similar symptoms.
Once we confirm the flame sensor is faulty, we carefully remove the old component and install a new one matched to your furnace model. Flame sensors are precision instruments, so proper installation is critical for safe operation. We test the furnace through multiple heating cycles to make sure the new sensor works correctly and the system holds a steady flame.
If we discover other furnace components are worn or dirty during inspection, we will explain your options so you can make informed decisions about additional repairs.
Flame sensor replacement typically costs less than many other furnace repairs, making it one of the more affordable solutions when your furnace fails to heat properly. The final price depends on several factors:
Comparing this to more involved repairs like furnace igniter replacement, flame sensor replacement is often the more budget-friendly option for common ignition problems. However, if your gas furnace repair needs extend beyond the flame sensor, costs may increase.
We provide upfront pricing before starting any work so you know exactly what to expect.
The flame sensor is a safety device that detects whether a flame is actually burning in your furnace. When your furnace ignites, the flame sensor confirms the flame is present. If no flame is detected, the sensor shuts off gas flow to prevent unburned gas from accumulating in your home. This safety feature protects your family from potential gas leaks.
Sometimes a dirty flame sensor can be cleaned and restored to working order. However, if the sensor is worn, corroded, or damaged, cleaning will not fix the problem. Our technicians assess the condition of your flame sensor during diagnosis and recommend cleaning or replacement based on its actual state.
Cold weather puts extra demand on your heating system, causing more frequent cycling. This increased operation can expose a weak flame sensor that struggles to keep up. Temperature changes can also affect how your furnace components perform. If your furnace works intermittently, the flame sensor may be failing gradually and struggling under heavy demand.
Flame sensors typically last 5 to 10 years depending on furnace usage, maintenance history, and environmental factors. Regular HVAC maintenance can extend component life, but eventually these safety devices wear out and require replacement.
Not always. A failing flame sensor often causes your furnace to shut down or fail to stay lit, which results in no heat. This can be part of furnace not heating repair diagnostics, but other problems like thermostat issues, blower failures, or gas supply problems can also cause heating failures. Our technicians diagnose the root cause to ensure we address the actual problem.
