FAQs
What are common signs of an igniter failure in my furnace or heat pump?
Typical symptoms include the furnace repeatedly cycling without igniting, a clicking sound but no burner flame, cold air coming through vents when the thermostat calls for heat, or a sudden spike in utility bills as the system struggles to start. If you notice any of these issues in your Whitwell home, it’s best to shut the unit off and call for professional service to avoid further damage.
Why does the igniter in my heating system stop working?
Igniters can fail for several reasons: natural wear over time (most last 3–7 years), power surges, dirt or moisture accumulation on the igniter surface, improper voltage, or a cracked hot-surface igniter element. In some Whitwell homes, high humidity in crawl spaces or fluctuating power supply can speed up deterioration. Regular maintenance helps spot early warning signs before total failure.
Can I reset or clean the igniter myself to restore heat?
While homeowners can inspect basic items like the circuit breaker or furnace filter, working directly on an igniter is not recommended. The component is fragile and easily broken, and handling it without proper tools can lead to personal injury or voided warranties. A certified HVAC technician has the correct meters to test resistance and the expertise to install a factory-approved replacement safely.
How quickly can your Whitwell HVAC team replace a faulty igniter?
In most cases we can provide same-day service. Our vans are stocked with the most common hot-surface and spark igniters used by leading furnace brands. After a diagnostic visit (usually 30–45 minutes), replacing an igniter typically takes another 30 minutes, so your heat can be restored within a couple of hours of our arrival, weather and part availability permitting.
Will a new igniter fix all heating issues, or could there be other problems?
A failed igniter is a common culprit, but it’s not the only cause of ignition problems. Faulty limit switches, blocked flue vents, gas-valve failures, or control board issues can mimic igniter symptoms. Our technicians perform a full ignition sequence test to ensure we address the root cause—not just swap parts—so you won’t face repeated breakdowns when temperatures drop in Whitwell.
How can I prevent future igniter failures and extend my furnace’s life?
Schedule professional maintenance each fall. This service includes cleaning the burners, checking ignition voltage, inspecting wiring, and measuring igniter resistance to catch small issues early. Keep air filters clean to ensure proper airflow, install surge protection to guard electronic components, and maintain recommended humidity levels in your home. Following these steps can double the lifespan of your igniter and keep your heating system running reliably through Whitwell winters.
