The Part That Lights Your Furnace Is Also the First to Wear Out
Modern furnaces do not use a standing pilot light. Instead, a small ceramic element heats to a glowing orange in a matter of seconds, ignites the gas, and then cools back down. It does that every single cycle, and thermal stress eventually cracks it. Igniters are among the most commonly replaced parts in any heating system for exactly that reason. Mighty Air, LLC handles HVAC Hot Surface Igniter Replacement in Jacksonville, FL, and surrounding areas.

Handled Correctly, Because They Break Easily
Hot surface igniters are fragile in a specific way. The ceramic cracks from a fingertip, from being installed at the wrong angle, or from being torqued a fraction too tight, and a brand new one can fail on the first cycle if it was handled carelessly. Our licensed technicians install them by the manufacturer’s method with the correct part number for your furnace, then verify a clean, consistent light across multiple cycles before we call the job done.
Signs the Igniter Has Failed
The pattern is usually recognizable once you know what to watch and listen for:
- The inducer and blower run but the burners never light
- An audible click and a short delay, then nothing
- Lockout after three or four attempted ignition tries
- No visible orange glow at the igniter during startup
- Visible cracks, chips, or white residue on the element
- Heat that works intermittently and gets worse over time
Ignition problems occasionally point elsewhere, so ask about Heater Parts Replacement, HVAC Pressure Switch Replacement, and Heating Repair while we have the panel off.
