FAQs
What are the most common signs of a faulty furnace or heat-pump igniter?
Typical warning signs include the blower running without warm air, repeated on-off cycling, a clicking sound without ignition, a constant glowing igniter that never lights the burners, and a system fault code on modern control boards. If you notice any of these issues in your Maryville home, the igniter is likely worn or cracked and should be inspected right away to avoid a complete loss of heat.
Why does an igniter fail in a heating system?
Igniters are made from silicon carbide or silicon nitride and operate at 1,200–1,800°F. Over time, this intense heat, combined with voltage spikes, vibration, dust buildup, and improper handling during filter changes, can cause the element to crack or erode. High humidity in crawlspaces, a misadjusted gas valve, or a dirty flame sensor can also shorten an igniter’s life. Regular maintenance reduces these stresses and helps the component last its full 5–7-year average lifespan.
Is it safe to replace a furnace igniter myself?
Although igniters are relatively inexpensive parts, replacing them involves shutting off gas and electrical supplies, handling a fragile ceramic element, and recalibrating flame-sensing and gas pressures. An incorrect installation can damage the control board or create delayed ignition, which is a fire hazard. For safety, warranty protection, and code compliance, we recommend scheduling a licensed Maryville HVAC technician to perform the repair.
How fast can your Maryville technicians respond if my igniter stops working?
During the heating season we keep common igniters in stock on every service truck. For most calls placed before noon, we can arrive the same day, often within 2–4 hours. After-hours emergency service is also available, ensuring your family isn’t left without heat overnight or through the weekend.
Will fixing a faulty igniter improve my energy bills?
Yes. A weak or partially cracked igniter can cause short cycling and extended warm-up times, both of which waste gas and electricity. Restoring reliable ignition lets the furnace reach its steady-state efficiency faster and keeps runtimes consistent, which often lowers monthly utility costs and reduces wear on other components like the blower motor.
What does professional igniter repair cost in Maryville and what is included?
Most residential igniter repairs range from $150–$300, depending on model accessibility and whether after-hours service is required. The price covers diagnostic testing, the OEM-approved igniter, labor, gasket replacement if needed, system safety check, and a one-year parts and labor warranty.
