What is going wrong in Hendersonville homes
A hot-surface ignitor glows hot to light the gas. Over years of heat cycles, that ceramic part can crack or wear thin. When it fails, you hear the furnace try, click, and shut down, because the control board will not open the gas valve without a working ignitor.
We do not guess at an ignitor. We test it, check the control sequence, and confirm the flame sensor and gas valve are not the real cause. That order matters, because a new ignitor will not fix a flame sensor fault.
How we fix it
Ignitor testing
We measure the ignitor and watch the startup sequence, so we replace it only when it has failed.
Correct part match
We match the ignitor to your furnace model, since ignitors are not all the same shape or rating.
Handle with care
Hot-surface ignitors are fragile. We fit them without touching the heating surface, which can shorten life.
Full heat cycle test
We run a full cycle after the swap and check flame stability before we leave.
Why Hendersonville homeowners call us first
Ignitor calls are common in January, and they are often fixed in under an hour once the part is confirmed. We carry common ignitors on the truck to keep that visit short.
Safety comes first on gas work. If you smell gas, leave the house first, then call your gas utility or 911 from outside. Do not flip switches or light anything. Once the area is declared safe, call us at (615) 759-0528 and we will inspect the furnace before it runs again.
Repair or look at replacement
| Situation | Our guidance | Why |
|---|---|---|
| Clicking, no flame, unit under 12 years | Replace ignitor | A single part failure on a younger unit is a clear repair. |
| Ignitor fails again soon | Check voltage and controls | Repeat failure can point to a control or airflow issue. |
| Old furnace, many parts failing | Compare replace | One ignitor is cheap, but a pattern of failures changes the math. |
Hendersonville angle: Sumner County, ZIP 37075, and Old Hickory Lake
In Hendersonville, ignitor wear shows up fast during the first real cold snap, when furnaces that sat quiet all fall suddenly run all night. Homes in ZIP 37075 with older gas furnaces are the most likely to see this call in January.
Hendersonville sits on Old Hickory Lake, about 18 miles northeast of downtown Nashville, in Sumner County. Homes here range from older ranch homes to newer lake area subdivisions, and that mix means furnace age, duct layout, and venting can vary a lot from one street to the next. We check age, airflow, and safety controls on every visit, and we explain what we find in plain words before any work starts.

Frequently Asked Questions
How do I know the ignitor is bad?
Clicking with no flame, a furnace that tries and shuts off, and a cold house are classic signs. Testing confirms it before we replace anything.
How long does ignitor replacement take?
Often under an hour once the part is confirmed, plus a full heat cycle test.
Can I replace an ignitor myself?
Some homeowners can, but gas furnaces carry safety risks and fragile parts. If you are unsure, call us and we will handle it.
Why did my ignitor fail again?
Voltage issues, poor airflow, or a control fault can shorten ignitor life. We check those causes, not just the part.
Do you carry ignitors on the truck?
We carry the parts that fail most often, so many ignitor calls finish the same day.
