Ignitor & Flame Sensor Repair
We repair and replace furnace ignitors and flame sensors for homeowners across Florida and Georgia. If your furnace hums, clicks, runs for a few seconds and then shuts down, or cycles on and off without ever putting out warm air, a failed ignitor or a dirty flame sensor is one of the common causes. Check your thermostat settings and batteries, make sure the breaker has not tripped, and change a loaded filter. If the heat still will not hold, call us and we will come look. If you ever smell gas, leave the building first, call 911 or your gas utility, then call us.

What the Job Actually Involves
A hot surface ignitor is a small element that glows to light the burners, and a flame sensor is a thin rod that tells the control board the flame is really there. Both live inside the burner compartment, and both work with gas and line voltage, so this is not a homeowner repair. We shut off power and gas, open the cabinet, and test the parts in place before we touch anything. If the ignitor is cracked or the sensor is coated, we handle it on the visit where we can.
What We Check and What We Install
We start with the sequence of operation and watch what the furnace does on a call for heat. We measure the ignitor for continuity and correct resistance, read microamps at the flame sensor, and check the ground path, because a weak ground fakes a sensor failure often enough to catch people out. We clean or replace the sensor, fit the correct ignitor for your furnace, and confirm the burners light cleanly and stay lit through a full cycle before we pack up.
How We Decide It Is the Right Call
Symptoms overlap, so we do not guess. A furnace that lights and drops out after a few seconds usually points at the sensor. One that never lights at all, with no glow, points at the ignitor or the board feeding it. We also rule out pressure switches, a blocked flue, and a filter so dirty the heat exchanger is overheating. If the real problem is elsewhere, we tell you that instead of selling a part you do not need.

How long does a furnace ignitor last?
Ignitors wear out with cycles rather than years, so a furnace that runs hard through a cool snap ages one faster. Many last several seasons. When one fails, it usually fails suddenly with no warning.
Can a dirty flame sensor be cleaned instead of replaced?
Often yes. A light oxide film wipes off and restores the microamp signal. If the rod is pitted, cracked at the ceramic, or the reading stays low after cleaning, we replace it rather than leave you with short cycling.
Why does my furnace light and then shut off after a few seconds?
That pattern usually means the control board is not seeing proof of flame, so it closes the gas valve for safety. A dirty sensor or a poor ground is common. We test the signal and confirm before replacing parts.
How it works
- Step 1
Tell us the symptom
Call or fill out the quote form and describe what changed. Warm air, short cycling, a clicking outdoor unit, water on the floor. Details help us load the right parts before we drive out.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical side, refrigerant behavior, and the coil. Coils foul fast in coastal air, so we look there early. You get the finding in plain language before work starts.
- Step 3
Repair and verify
We make the repair, then run the system and watch it. Supply temperature, drain flow, amp draw, and how the house actually feels. If the fix needs a follow-up part, we tell you that day.

Why homeowners call us
- Humidity gets equal weightCold air alone is not comfort. On slab homes and older condos, a system can hit temperature and still leave the rooms clammy. We look at run time, airflow, and drainage so the house dries out instead of just chilling.
- Coastal wear is expectedSalt air chews condenser fins and contactors. We check for corrosion, weak capacitors, and fouled coils as part of the diagnosis, because in this region those are causes rather than afterthoughts.
- Heat gets attention tooFurnace repair, heat pump reversing valve trouble, and heat strip failures all come through in the cooler months. Georgia homes lean on heat harder than Florida homes, and we service both ends of the region.
- No mystery invoicesYou hear what failed, what it takes to fix, and what we found nearby that may fail next. If a repair does not make sense on an old system, we say so instead of stacking parts on it.
