How much does furnace ignitor replacement cost?

Ignitor replacement is one of the most affordable furnace repairs — typically $150 to $300 including parts and labor. We carry common ignitor types on our trucks for same-day repair.

How can I tell if the ignitor is the problem?

If your furnace cycles on, you hear the inducer motor run, but the burners never light and the system shuts down after a minute or two, the ignitor is the most likely culprit. Some furnaces will flash an error code indicating ignition failure.

How long do furnace ignitors last?

Typical lifespan is 5 to 7 years, though some last much longer. If your furnace is cycling excessively due to a thermostat issue or oversizing, the ignitor will wear out faster.

Professional Furnace Ignitor Replacement — Quick Heating Repair in Asheville & Western NC

The #1 Reason Your Furnace Won't Fire Up

Modern furnaces use either a hot surface ignitor (a glowing silicon carbide or silicon nitride element) or a spark ignition system to light the burners. Hot surface ignitors are fragile by nature — they operate at extremely high temperatures and become brittle over time. When one cracks or burns out, your furnace goes through its startup sequence but never actually lights. You might hear the draft inducer motor run, a click, and then nothing. This is the most common furnace repair we perform, and it's fast and affordable.

A 30-Minute Fix in Most Cases

Our technicians carry the most common ignitor types on every truck. After confirming the ignitor is the failed component — not a gas valve issue or control board problem — we swap in the replacement, verify the furnace lights and cycles properly, and check all safety controls. Most ignitor replacements take about 30 minutes from start to finish.

Preventing Future Failures

While ignitors do wear out naturally over time (average lifespan is 5-7 years), certain conditions can shorten their life: oil from fingerprints (never touch the element with bare hands), voltage spikes, and excessive short-cycling. During replacement, we inspect for conditions that may have contributed to premature failure.
