What the job involves
We shut off power and gas at the furnace before anything else, then pull the burner compartment cover to see the ignition sequence up close. A hot surface ignitor is a thin silicon carbide element that glows to light the burners. A flame sensor is a metal rod that proves flame is present. Both are wear parts. We test the ignitor for continuity, check the sensor's microamp signal, and clean or replace what has failed. Then we watch several full heating cycles before we pack up. Never open a gas furnace yourself.
What we check or install
We match the ignitor to your furnace, since a wrong part cracks quickly or never reaches temperature. Flame sensors get cleaned with fine abrasive cloth and reseated so they sit correctly in the flame. While the panel is open we look at burner condition, the gas valve, the control board's fault codes, wiring and grounding, and the heat exchanger surface. Poor grounding causes flame sensing faults that look like a bad sensor. On older heat pumps with propane or gas backup, we test the changeover too.
How we decide it is the right call
The symptoms tell us a lot. If the ignitor glows and burners never light, the problem is gas delivery, not the ignitor. If burners light and die after roughly five to ten seconds every time, we are looking at flame sensing. If nothing glows at all, we test the ignitor, then the control board that feeds it. Sometimes the honest answer is that the furnace has other failures stacked up and a repair buys a season. We will tell you which one you are looking at.

How long does a flame sensor cleaning last?
Often a full heating season or more, depending on burner condition and combustion air quality. If a cleaned sensor fails again within weeks, something else is wrong, usually grounding, a cracked ignitor or dirty burners.
Can a bad ignitor damage anything else?
A failing ignitor mostly leaves you without heat, but repeated failed ignition attempts put wear on the gas valve and control board. Getting it replaced early keeps the repair limited to one part.
I smell gas near my furnace. What should I do?
Leave the building right away, take everyone with you, then call 911 or your gas utility from outside. Do not touch switches or the furnace. Once they clear the home, call us and we will inspect the ignition system.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form with what the system is doing. Warm air, no air, short cycling, a smell, a breaker that keeps tripping. That detail helps us load the right parts before we roll.
- Step 2
We schedule around travel
Hill-country routes take time, so we give you a realistic window instead of a guess. If you are on a long county road, we tell you that up front and keep you posted if the day shifts.
- Step 3
Diagnose, then explain
We test the system, find the actual fault and walk you through what failed and what the repair involves. You decide before we start. If a part has to be ordered, we say when it lands.

Why homeowners call us
- Older systems are normal herePlenty of homes on our routes run a heat pump from two decades back, a propane furnace and a wood stove for the cold snaps. We repair what you have rather than pushing you toward replacement on the first visit.
- Heating and cooling bothSame crew handles air conditioning repair in summer and heating repair in winter. That means we know your system's history when the season flips, and we are not learning your ductwork from scratch in January.
- We say what we do not knowIf a fault is intermittent, we tell you that instead of replacing parts on a hunch. Sometimes the honest answer is a monitoring period or a second visit when the weather brings the problem back.
- Regional coverage, local paceWe cover Arkansas, Missouri, Mississippi, Oklahoma and Tennessee. Travel time is part of every job we quote, so you get a window that accounts for the drive rather than a promise that falls apart.
- All major brands, gas & electricEvery major HVAC brand, gas and electric, handled by an independent crew.
- Straight answersNot worth fixing? We say that out loud, and often it saves you the visit fee.
