What is included
What Our Pilot Repair Includes
Every pilot call covers the diagnostic, the safety circuit test, and a full ignition cycle. Parts are quoted separately if they are needed, and we tell you the price before we install anything.
Full Diagnostic
We test the thermocouple output under load, check the flame sensor signal, and read gas pressure with a manifold gauge set. This tells us whether the pilot failure is the thermocouple, the orifice, or the gas valve.
Thermocouple or Sensor
If the thermocouple or flame sensor has failed, we replace it with a Honeywell or White-Rodgers part matched to your furnace. The old part is left with you so you can see what failed.
Pilot Orifice Cleaning
A dirty pilot orifice is a common cause of a weak or yellow flame. We remove and clean the orifice, then set the flame so it properly engulfs the thermocouple.
Ignition Cycle Test
After the repair we run three full ignition cycles and watch the pilot, the main burners, and the flame sensor signal. We also check temperature rise against the data plate to confirm the furnace is running to spec.
Safety Inspection
We inspect the heat exchanger, limit switches, and inducer motor while the furnace is open. If we find a cracked heat exchanger or a tripped limit switch, we tell you before the furnace goes back into service.
Filter Check
A clogged furnace filter causes limit switch trips and short cycling, which can look like a pilot problem. We check your filter and swap it if it is loaded, so the repair actually holds.

Service overview
Furnace Pilot Light Repair Lima OH: What It Involves
Furnace pilot light repair Lima OH is the trade of diagnosing and restoring a standing pilot flame on a gas furnace, then correcting whatever keeps putting it out. On a standing-pilot system, the flame heats a thermocouple or flame sensor that tells the gas valve it is safe to open. When that signal drops, the valve closes and you get no heat. We test the thermocouple with a thermocouple tester, check the flame sensor with a flame sensor tester, and read gas pressure with a manifold gauge set. If the pilot lights but dies within seconds, the problem is usually the safety circuit, not the flame itself.
Lima sits in a cold pocket of Allen County, and October is when we start getting the first no-heat calls. Older homes near downtown and in the 45801 and 45804 ZIP codes still run standing-pilot furnaces from Carrier, Trane, and Lennox, and a pilot that keeps going out is the first sign of a tired thermocouple. If you are searching for furnace pilot repair near me Lima, that usually means the flame will not hold at all. We also see it in rentals and small shops where the furnace sat all summer and the pilot orifice collected dust. A furnace pilot light repair in Lima OH near me call is almost always same-day.
- Heat Back Same Day — Most pilot calls are finished in one visit. We carry thermocouples, flame sensors, and igniters on the truck, so a furnace pilot fix Lima usually takes 60 to 90 minutes from arrival to a running furnace. If the gas valve or control board is the real problem, we quote it before we start.
- We Fix the Cause — Relighting a pilot without testing the safety circuit just means it goes out again next week. We test the thermocouple output in millivolts, check the flame sensor, and inspect the pilot orifice for debris. That is how furnace pilot light service Lima OH should work, and it is why our callbacks stay low.
- Safety Checked Every Time — Any time we open a combustion chamber we inspect the heat exchanger, check the limit switches, and look at the inducer motor. A cracked heat exchanger or tripped limit switch is a bigger problem than a pilot, and you want to know about it now, not in January. We follow OSHA safety compliance on every gas call.
- Straight Pricing Up Front — You get the price before we turn a wrench. Affordable furnace pilot repair Lima Ohio does not mean cheap parts, it means we tell you what the job costs and why. Diagnostic, thermocouple swap, and ignition test are quoted as one number, and we honor it.
- Same-Day Pilot Calls — We hold same-day slots for no-heat calls, including evenings. Most furnace pilot light repair Lima Ohio requests in the 45801, 45804, and 45805 ZIP codes get a tech the same day. If your pilot is out and the house is cold, say so on the phone and we will work you in.
- Parts on the Truck — Thermocouples, flame sensors, igniters, and pilot orifices ride on every truck. That means one visit instead of two. We match the part to your furnace brand, whether it is a Carrier, Rheem, or York standing-pilot unit, and we test it before we pack up.
- We Explain the Failure — You will see the failed thermocouple or dirty flame sensor and understand why it quit. If we find a cracked heat exchanger or a bad blower motor, we show you and give you options. That is how furnace pilot light repair in Lima OH near me should be handled, with the customer in the loop.
- Emergency Pilot Repair — Emergency furnace pilot light repair Lima OH is available 24/7 when the temperature drops and the pilot will not hold. We answer the phone at night, and we do not charge a different rate just because it is late. Call (419) 287-8289 and we will get your heat back.
The service timeline
How Our Pilot Repair Process Works
Phone Triage
We ask what the furnace is doing: no flame, flame that dies, or no heat at all. That tells us whether to bring a thermocouple, a flame sensor, or a control board. You get a two-hour arrival window, and we call when we are on the way. If it is below freezing, tell us and we move you up the list.
Diagnose the Circuit
We pull the burner door, inspect the pilot assembly, and test the thermocouple with a thermocouple tester. A reading under 20 millivolts under load means the thermocouple is failing. We also check gas pressure with a manifold gauge set and look for a dirty pilot orifice. This takes 20 to 30 minutes.
Repair and Replace
Most jobs are a thermocouple or flame sensor replacement, plus a pilot orifice cleaning. We use Honeywell and White-Rodgers parts that match your furnace brand. If the gas valve or control board has failed, we show you the failed part and quote the replacement before we install it. No surprises.
Full Ignition Test
After the repair we run the furnace through three full ignition cycles. We watch the pilot light, confirm the main burners carry over, and check the flame sensor signal with a multimeter. Then we let it run 15 minutes and check the temperature rise against the data plate. If it short cycles, we find out now.
Walkthrough and Filter
Before we leave we show you what failed, what we replaced, and how to shut the furnace down if you ever smell gas. We check your furnace filter and swap it if it is clogged, because a dirty filter causes limit switch trips and short cycling. You get the old part and a written summary of the work.
Tools and methods01 02 03 04 05 06 07 08 09 10 11
Tools and Methods We Use
Thermocouple tester
Reads the millivolt output of a standing-pilot thermocouple under load, which tells us whether it is strong enough to hold the gas valve open.
Flame sensor tester
Measures the microamp signal on intermittent-ignition furnaces so we know whether the sensor is reading the flame correctly or needs cleaning or replacement.
Manifold gauge set
Checks inlet and manifold gas pressure against the furnace data plate, which matters on propane systems and older natural gas furnaces in Lima.
Multimeter
Tests control board outputs, gas valve voltage, and limit switch continuity so we can pinpoint an open safety circuit instead of replacing parts blindly.
Combustion analyzer
Verifies combustion after a pilot or burner repair, checking carbon monoxide and oxygen levels to confirm the furnace is burning clean.
Inspection camera
Lets us look inside the heat exchanger and flue passages without a full teardown, so we can check for cracks during a pilot repair.
Clamp meter
Measures blower motor and inducer motor amp draw to confirm they are running within spec and not tripping the limit switch.
NATE-certified diagnostics
Our technicians follow NATE testing standards for gas furnace ignition and safety circuits. That means we test thermocouple output, flame sensor signal, and gas pressure in a set order, so nothing gets missed on a no-heat call.
ACCA temperature rise check
After any pilot or ignition repair we measure temperature rise across the heat exchanger and compare it to the data plate. If it is off, we check airflow, the filter, and the blower before calling the job done.
EPA Section 608 compliance
Our techs hold EPA Section 608 certification, which covers safe handling of regulated substances and combustion-side work. It is part of how we keep every gas call code-correct and safe.
Ohio HVAC license and OSHA compliance
We work under an Ohio HVAC license and follow OSHA safety compliance on every combustion job. Gas work is not a place to cut corners, and our process reflects that from the first test to the final ignition cycle.
Where this service helps
When to Call for Pilot Repair
First cold snap in October and the furnace will not light after sitting all summer.
We come out, clean the pilot orifice, test the thermocouple, and check the gas valve. Summer dust and spider webs in the pilot assembly are common after months of no use. Heat back the same day, usually within 90 minutes of arrival, and a furnace that is ready for the heating season.
You smell gas near the furnace and the pilot will not stay lit.
Leave the house and call us from outside. We treat every gas smell as an emergency, shut the gas off, and test the valve, pilot assembly, and connections before we relight anything. A safe, tested furnace or a clear answer about what needs to be replaced before it can run again.
A rental property in Breña has a tenant with no heat and the pilot keeps dying.
We schedule around the tenant, diagnose the thermocouple and gas valve, and repair the cause. We document the work so you have a record for the property file. A tenant with heat, a documented repair, and fewer after-hours calls for the same furnace.
The pilot lights but the furnace short cycles and never warms the house.
We test the ignition system, check the flame sensor, and look at the limit switch and filter. Short cycling after a pilot repair usually means airflow or a limit issue, not the pilot itself. Full heating cycles, even temperatures, and a furnace that runs to the data plate temperature rise.
You are selling a home in the 45805 ZIP code and the inspection flagged the pilot.
We inspect the pilot assembly, test the thermocouple, and repair or replace what failed. We provide a written summary of the work for the buyer and the agent. A clear repair record, a furnace that passes reinspection, and no last-minute surprises at closing.
Local execution
How Pilot Repair Runs in Lima
Lima's housing stock is a mix of older homes with standing-pilot furnaces and newer builds with intermittent ignition. In the 45801 and 45804 ZIP codes near downtown, we still see plenty of Carrier, Trane, and Lennox standing-pilot units from the 1990s, and their pilot assemblies are the first thing to fail when fall arrives. Allen County winters swing hard, and a thermocouple that reads marginal in October will drop out in January. That is why we test millivolt output under load instead of just looking at the flame. If you need furnace pilot light repair Lima Ohio on a cold weekend, we keep emergency slots open. We also see propane systems on the edges of the county, and those need the manifold pressure set to the data plate, not guessed. Our trucks carry the thermocouples, flame sensors, and pilot orifices that match the brands we see most, so most furnace pilot light repair in Lima OH near me calls are finished in one visit.
Cercado de Lima
Older housing with standing-pilot furnaces and original gas piping. Pilot assemblies here often need orifice cleaning and thermocouple replacement.
Breña
A lot of rental properties with furnaces that sit unused in summer. Dust in the pilot orifice is the most common no-heat cause we find here.
San Martín de Porres
Mix of older and newer homes. We see both standing pilots and hot-surface igniters, so we diagnose the ignition type before quoting parts.
Los Olivos
Newer builds with intermittent-ignition furnaces. Flame sensor faults are more common than standing-pilot failures in this area.
Comas
Cold, exposed homes where a weak thermocouple drops out first. We test under load and replace anything reading below 20 millivolts.
Cold snaps that push furnaces to their limit
A marginal thermocouple that works in mild weather will fail when the furnace runs constantly. We test under load so the repair holds through the coldest week.
Older gas piping and standing-pilot systems
Older homes in central Lima often have pilot assemblies that need cleaning and gas pressure verification. We check both before we call the job done.
Furnaces idle all summer
Dust, spider webs, and corrosion collect in the pilot orifice over the off-season. That is why October brings a wave of no-light calls, and why we clean the orifice on every pilot repair.
Propane systems outside the city core
Propane furnaces need different manifold pressure settings than natural gas. We set pressure to the data plate and verify combustion with an analyzer.

Before and after
What a successful service visit changes.
Standing Pilot Would Not Hold
Before
A homeowner in Cercado de Lima had a Carrier furnace whose pilot lit but died within 10 seconds. They had relit it four times over two days and the house was down to 60 degrees. The thermocouple was reading 12 millivolts under load, well below the 20 millivolts needed to hold the gas valve open.
After
We replaced the thermocouple with a Honeywell part, cleaned the pilot orifice, and set the flame to a sharp blue. The furnace ran three full ignition cycles and held. Temperature rise came in at 42 degrees, within the data plate range.
Maintenance: Check your furnace filter monthly and have the pilot assembly cleaned each fall. A thermocouple typically lasts three to five years, so note the replacement date for next season.
Dirty Orifice Caused No Heat
Before
A rental in Breña had a York furnace that would not light after sitting all summer. The pilot orifice was packed with dust and spider webs, and the flame was yellow and lazy. The tenant had no heat and the landlord was getting calls every night.
After
We cleaned the pilot orifice and burner assembly, verified gas pressure with a manifold gauge set, and replaced the flame sensor as a precaution. The furnace lit on the first try and ran full cycles. No repeat calls that season.
Maintenance: Have the furnace started up in early fall before tenants need heat. A 30-minute tune-up in September prevents most October no-heat calls.
Gas Valve Failure After Pilot Repair
Before
A homeowner in San Martín de Porres had a furnace whose pilot stayed lit but the main burners never opened. A previous visit had only relit the pilot. The gas valve was not opening even with 24 volts at the terminals, and the furnace was blowing cold air.
After
We tested valve voltage with a multimeter, confirmed the valve had failed, and replaced it with a White-Rodgers valve matched to the furnace. The burners carried over immediately, and temperature rise checked out at 45 degrees.
Maintenance: If the pilot lights but you get cold air, stop relighting and call for a gas valve test. Annual service catches valve issues before they leave you without heat.
Problems we solve
Pilot Problems We Fix in Lima
A pilot that will not light, will not stay lit, or lights and dies is the same call for us. Here are the failures we see most in Lima and how we handle them.
Pilot will not light at all
No heat, and the house drops fast on a cold Lima night. If you smell gas, leave the house and call from outside. We check gas supply, test the gas valve, and inspect the pilot orifice for debris. If the thermocouple is dead, we replace it and test the full ignition cycle before we leave. Most no-light calls are fixed in one visit.
Pilot lights but goes out in seconds
The furnace never reaches the main burners, so you get cold air from the vents and a furnace that short cycles. This is almost always a weak thermocouple or a flame sensor out of spec. We test the millivolt output under load and replace the failed part. We also check the pilot flame position so it engulfs the thermocouple properly.
Pilot keeps going out every few days
You relight it, it runs, then it quits again. Repeated relights mask a failing safety circuit and can leave you without heat when you are away. We test the thermocouple, clean the orifice, and check the gas valve and control board. If the safety circuit is opening intermittently, we find it with a multimeter and fix the actual cause instead of just relighting.
Furnace lights then blows cold air
The blower runs but the burners never carry over, so the house stays cold and the furnace cycles on the limit switch. We test the ignition system and gas valve, confirm the burners light, and check the flame sensor signal. If the blower motor or limit switch is the real problem, we diagnose it and quote the repair.
Yellow or lazy pilot flame
A yellow flame does not heat the thermocouple enough, so the pilot drops out. It also points to incomplete combustion and possible carbon buildup. We clean the pilot orifice and burner assembly, check gas pressure with a manifold gauge set, and set the flame to a sharp blue. Then we verify the thermocouple reading and run the furnace through full cycles.
Pricing and expectations
What Pilot Repair Costs in Lima
$150 - $850 depending on scope
Typical 2026 pricing for furnace pilot light repair in Lima runs $150 to $400 for a diagnostic, thermocouple or flame sensor replacement, and a full ignition test. If the gas valve or control board has failed, expect $400 to $850. We quote the price before we start, and the diagnostic fee is credited toward the repair when you approve the work. Affordable furnace pilot repair Lima Ohio means honest pricing, not cheap parts. We use OEM-matched thermocouples and flame sensors so the repair lasts.
You are paying for a diagnosis, not a guess. We test the safety circuit, replace only the failed part, and run full ignition cycles before we leave. That is what keeps the pilot lit and keeps you from paying for the same call twice.
Furnace brand and age
Parts for older Carrier, Trane, and Lennox standing-pilot furnaces are usually in stock. Some discontinued control boards take longer to source and cost more, and we tell you that before ordering.
Failed component
A thermocouple or flame sensor replacement is the low end of the range. A gas valve, control board, or inducer motor pushes the job higher. We show you the failed part and quote the replacement before installing it.
Access to the furnace
A furnace in a closet or basement is quick to work on. A unit in a tight attic or behind finished walls takes longer, and that labor shows up in the price. We tell you on the phone if access will affect the quote.
Time of call
Emergency furnace pilot light repair Lima OH is priced the same as a daytime visit. We do not add a night or weekend surcharge just because the pilot picked a bad time to quit.
Related repairs found
If we find a cracked heat exchanger, a tripped limit switch, or a failing blower motor during the pilot repair, we quote that work separately. You decide what to do and when.
Proof behind the promise
Licensed, Certified, and Local
Technical expertise
Local Experience With Standing-Pilot Systems
Our technicians work on standing-pilot and intermittent-ignition furnaces every week across Lima and Allen County. We hold NATE certification and EPA Section 608, and we carry an Ohio HVAC license. That matters because a pilot problem on a 1990s Carrier furnace is a different diagnosis than a failed hot-surface igniter on a 2018 Goodman. We keep thermocouple testers, flame sensor testers, combustion analyzers, and clamp meters on every truck. We also stock igniters, flame sensors, thermocouples, limit switches, and gas valves for the brands we see most: Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana.
- NATE-certified technicians who test thermocouple millivolt output under load, not just visually.
- EPA Section 608 handling for refrigerant and combustion-side diagnostics on every gas call.
- Ohio HVAC license held by the company, with OSHA safety compliance on all combustion work.
- We follow ACCA standards for temperature rise and airflow checks after every pilot repair.
- Trucks stocked with Honeywell and White-Rodgers thermocouples, flame sensors, and gas valves.
Customer stories
Reviews From Lima Customers
Dana R.Homeowner, Cercado de Lima
Our old Carrier furnace pilot would not stay lit, and the house was down to 58 degrees. The tech tested the thermocouple, showed me the low millivolt reading, and swapped it in about an hour. He also cleaned the pilot orifice and checked the heat exchanger. Heat was back the same afternoon and it has held all month.
Marcus T.Landlord, Breña
I manage three rentals and one of the York furnaces kept losing its pilot. Lima Furnace Repair Pros came out, found a dirty orifice and a weak thermocouple, and fixed both. They documented everything for the tenant file and the price matched the quote. I have used them on two other units since.
Elena V.Homeowner, San Martín de Porres
Called at 9 p.m. when the pilot went out and the temperature was dropping. They answered, gave me a price, and had a tech here within two hours. He relit the pilot, tested the gas valve, and ran three ignition cycles before leaving. No extra charge for the late call. That is why I saved their number.
How much does furnace pilot light repair cost in Lima OH?
Most furnace pilot light repairs in Lima run $150 to $400 in 2026, including the diagnostic, a new thermocouple or flame sensor, and the ignition test. If the gas valve or control board has failed, expect $400 to $850. We quote the price before we start, and the diagnostic fee is credited toward the repair when you approve the work.
Who repairs furnace pilot lights in Lima Ohio?
We do. Lima Furnace Repair Pros handles furnace pilot repair in Lima for standing-pilot and intermittent-ignition systems. Our techs are NATE-certified and carry an Ohio HVAC license. We work on Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana furnaces, and we stock the thermocouples and flame sensors those units use. Call (419) 287-8289.
Why does my furnace pilot light keep going out in Lima?
A pilot that keeps going out in Lima is almost always a weak thermocouple, a dirty pilot orifice, or a flame sensor that has drifted out of spec. Cold weather makes a marginal thermocouple fail faster. We test the millivolt output under load, clean the orifice, and replace the failed part so the flame holds through the whole heating season.
Can I relight my furnace pilot light myself in Lima OH?
You can relight a standing pilot if you follow the lighting instructions on the furnace door and you smell no gas. If the flame will not hold after two tries, stop and call us. A pilot that dies repeatedly points to a failed thermocouple or a gas valve issue, and those need a licensed tech. Call (419) 287-8289.
