What is included
What Our Gas Furnace Repair Includes
Every gas furnace repair call includes a full diagnostic, a written flat-rate price, the repair itself, and a combustion test before we leave. Here is what is covered on a standard visit, and what we quote separately if your system needs it.
Full Diagnostic and Fault Codes
We pull board fault codes, test the igniter, flame sensor, thermocouple, limit switches, and gas valve with a multimeter and clamp meter, and inspect the heat exchanger with an inspection camera. You get the findings in plain English.
Flat-Rate Repair Pricing
Before we start, you get one flat price for the repair, parts and labor included. No hourly clock running while we work. If we find a second problem mid-repair, we stop and quote it before touching anything else.
Common Part Replacement
Igniters, flame sensors, thermocouples, limit switches, and universal control boards are on the truck. We replace the failed part with an OEM or equivalent component and verify it against the manufacturer's spec.
Combustion and Safety Test
After the repair, we run a full heat cycle, check temperature rise against the data plate, and take a combustion reading with an analyzer. If we find a cracked heat exchanger or a gas leak, we red-tag the furnace and explain your options.
Filter and Airflow Check
We check your furnace filter, blower wheel, and static pressure as part of every call. Restricted airflow is a top cause of limit switch trips and short cycling, so we flag it before it becomes your next repair.
Written Warranty on Labor
Our labor is warrantied for 90 days, and the parts we install carry their manufacturer warranty. If the same component fails inside the labor window, we come back and make it right at no charge.

Service overview
What Gas Furnace Repair in Lima Actually Involves
Gas Furnace Repair in Lima is the diagnostic and mechanical work of finding out why a gas-fired furnace stopped heating and correcting the failed component. That means testing the igniter, flame sensor, thermocouple, gas valve, inducer motor, and control board with a multimeter and combustion analyzer, then replacing what has failed. Most no-heat calls trace back to a dirty flame sensor, a failed igniter, or a tripped limit switch. We confirm the repair with a combustion test before we leave.
Lima winters push furnaces hard from October through April, and Allen County's older housing stock means plenty of systems running past 15 years. When your furnace blows cold air or short cycles at 2 a.m., you want gas heating repair near me Lima that answers the phone. We stock Carrier, Trane, Lennox, Goodman, and Rheem parts on the truck so affordable gas furnace repair Lima Ohio doesn't mean a three-day wait for a control board.
- Same-Day No-Heat Service — We run same-day gas furnace repair in Lima on most calls before 2 p.m., and 24/7 emergency dispatch for total heat loss. Our trucks carry igniters, flame sensors, thermocouples, and universal control boards, so roughly 8 out of 10 repairs finish on the first visit.
- Flat-Rate Upfront Pricing — You get the diagnostic fee and the repair price before we touch a wrench. Typical 2026 gas furnace repair cost Lima OH runs $180 to $450 for common ignition and sensor fixes, and $600 to $1,400 when a blower motor or inducer motor needs replacing. No surprise line items.
- NATE-Certified Technicians — Every tech on our team holds NATE certification and works under an Ohio HVAC license with EPA Section 608 handling credentials. We test with a combustion analyzer and manifold gauge set on every gas-side repair, not just a visual once-over.
- Repairs Backed in Writing — Parts we install carry a manufacturer warranty, and our labor is warrantied for 90 days. If the same flame sensor or gas valve fails inside that window, we come back at no charge. That is the difference between a patch and a repair.
- We Stock What Fails — Igniters, flame sensors, thermocouples, limit switches, and universal control boards ride on every truck. That is why most gas furnace fix Lima jobs finish the same visit instead of waiting on a parts order. We also carry Honeywell and White-Rodgers controls, the two brands we see most in Lima.
- We Test, Not Guess — A furnace not turning on can be five different things. We use a manifold gauge set, multimeter, and combustion analyzer to prove the failure before we quote a repair. If your flame sensor reads below spec, you get the reading, not a sales pitch for a new furnace.
- We Cover Allen County — From Cercado de Lima to San Juan de Lurigancho and out to Carabayllo, we run gas heating repair company Lima OH calls seven days a week. Neighborhoods like Miraflores and San Isidro get the same two-hour windows as everywhere else. No extra trip charge inside our service area.
- We Fix the Cause — Short cycling usually means a dirty filter, an oversized furnace, or a failing limit switch, not a bad thermostat. We chase the root cause so you are not calling us back in three weeks. That is how emergency gas furnace repair Lima OH should work: fix it once, fix it right.
The service timeline
Our Gas Furnace Repair Process
Phone Triage
When you call (419) 287-8289, we ask what the furnace is doing: not turning on, blowing cold air, short cycling, or making strange noises. That tells us which parts to load and whether this is a same-day or emergency slot. Most calls get a two-hour arrival window.
Full Diagnostic
The tech pulls the fault codes, then tests the igniter, flame sensor, thermocouple, limit switches, and gas valve with a multimeter and clamp meter. We inspect the heat exchanger with an inspection camera for cracks. This takes 30 to 45 minutes and ends with a written repair price.
Repair Approval
You get the diagnosis in plain English and a flat-rate price before any work starts. If it is a $200 flame sensor cleaning and igniter swap, we say so. If the heat exchanger is cracked and the furnace is unsafe, we tell you that too, and you decide how to proceed.
The Repair
Most ignition, sensor, and control board repairs take one to three hours. Blower motor and inducer motor replacements run three to five hours because of the disassembly involved. We use a blower motor puller and fin comb to protect the wheel and coil during the swap.
Test and Verify
Before we pack up, we run a full heat cycle, check temperature rise against the data plate, and take a combustion reading with the analyzer. You get the old parts, a written invoice, and a reminder to change your furnace filter every 60 to 90 days.
Tools and methods01 02 03 04 05 06 07 08 09 10 11
Tools and Methods We Use
Manifold Gauge Set
Measures gas manifold pressure on natural gas and propane furnaces so we can confirm the gas valve is delivering the correct pressure to the burners.
Combustion Analyzer
Reads carbon monoxide, oxygen, and flue temperature after a repair. We use it on every gas-side job to confirm the furnace is burning clean and safe.
Multimeter and Clamp Meter
Tests igniter resistance, flame sensor microamps, control board outputs, and blower motor amp draw. This is how we prove which component failed instead of guessing.
Inspection Camera
Lets us look inside the heat exchanger for cracks without pulling the furnace apart. A cracked exchanger is a carbon monoxide risk and a red-tag condition.
Blower Motor Puller and Fin Comb
Removes the blower wheel without bending it and straightens coil fins after cleaning. Protects parts that are easy to damage during a motor swap.
Thermocouple and Flame Sensor Testers
Verifies standing-pilot thermocouples and flame sensors read within spec. A sensor that reads low will shut the furnace down even when it looks clean.
Vacuum Pump
Used on gas valve and control work where moisture or debris needs to be cleared from the line before reassembly.
NATE Certification Standards
Our techs are tested to NATE standards for gas heating diagnostics, which means they follow a documented sequence: verify call for heat, test ignition, prove flame, check airflow, and verify temperature rise. No shortcuts, no parts-swapping guesses.
EPA Section 608 Compliance
We follow EPA Section 608 rules for refrigerant and combustion safety, including leak checks and proper handling of any refrigerant circuits tied to the system. It keeps the job legal and your home safe.
ACCA Airflow and Load Standards
We check static pressure and temperature rise against ACCA guidelines. A furnace running outside its rated rise will short cycle and wear out early, so we correct airflow as part of the repair.
Ohio HVAC License and OSHA Compliance
All gas work is performed under an Ohio HVAC license with OSHA safety compliance on gas-line and electrical work. We shut gas at the valve, test for leaks, and verify combustion before restoring service.
Where this service helps
When Lima Homeowners Call Us
Your furnace quits on the first hard freeze of the season and the house drops below 60 degrees overnight.
We run 24/7 emergency dispatch for total heat loss. A tech arrives with igniters, sensors, and control boards on the truck, diagnoses the failure, and repairs it the same night whenever the part is on hand. Heat restored the same night in most cases, with a written invoice and a 90-day labor warranty on the repair.
Your furnace runs but the gas bill jumped and some rooms never get warm.
We check filter condition, blower speed, static pressure, and duct balance. Often a dirty filter or a blower running at the wrong speed is the whole problem, and correcting it costs far less than a new furnace. More even temperatures and lower gas usage, usually after a single service visit with no major parts replaced.
You are a landlord with a tenant calling about no heat in a Lima rental.
We schedule same-day gas furnace repair in Lima for rental properties, diagnose the issue, and quote the repair to you before work begins. We stock Goodman, Rheem, and Carrier parts common in rentals. Tenant has heat back the same day, and you get a written invoice and warranty documentation for your records.
Your older furnace has been repaired twice this season and you are wondering whether to fix or replace it.
We inspect the heat exchanger with an inspection camera and give you an honest read on remaining life. If the exchanger is cracked, we red-tag it for safety and walk you through replacement options without pressure. A clear decision: repair if the unit has life left, replace if it does not, with no guesswork and no surprise costs.

How Gas Furnace Repair Runs in Lima
Lima sits in a part of Ohio where winter nights regularly drop into the teens and single digits, and furnaces here run hard from October through April. That long heating season is why we see so many dirty flame sensors and failed igniters by mid-January. Allen County's housing stock ranges from older homes with standing-pilot furnaces to newer builds with high-efficiency condensing units, and both need different diagnostic approaches. When you call for gas heating repair Lima, we ask about the furnace age and brand on the phone so the tech arrives with the right parts. If you are searching for emergency gas furnace repair Lima OH on a Sunday night, we dispatch 24/7. We also see a lot of short cycling caused by undersized return ducts in older Lima homes, and we check static pressure on every call so the repair actually holds. Whether it is a Carrier in Miraflores or a Goodman in San Juan de Lurigancho, the process is the same: diagnose, quote, repair, verify.
Miraflores
A mix of older homes and renovated properties, many with furnaces past 15 years. We see a lot of standing-pilot and early electronic ignition systems here.
San Isidro
Newer construction with high-efficiency condensing furnaces. These units are sensitive to condensate drain issues and inducer pressure faults in cold weather.
San Juan de Lurigancho
Dense residential area with many rentals running Goodman and Rheem furnaces. Same-day parts availability matters here because tenants need heat fast.
Cercado de Lima
Older commercial and residential buildings with a wide range of furnace ages. We often find ductwork that needs airflow correction alongside the repair.
Carabayllo
Outlying properties, some on propane. We check orifice sizing and manifold pressure on propane furnaces here because the fuel burns differently than natural gas.
Long heating season from October through April
Furnaces run thousands of hours per year, which wears out igniters, flame sensors, and blower motors faster than in milder climates. Expect ignition-related repairs more often.
Winter nights in the teens and single digits
A no-heat call becomes urgent fast. We prioritize total heat loss calls for same-day or emergency dispatch so pipes do not freeze and the house stays livable.
Older housing stock with undersized return ducts
Restricted return air causes limit switch trips and short cycling. We measure static pressure and correct airflow as part of the repair rather than just resetting the switch.
Mixed natural gas and propane service areas
Propane furnaces need different orifice sizing and manifold pressure than natural gas. We confirm fuel type before quoting parts so the repair is correct the first time.

Before and after
What a successful service visit changes.
Failed Igniter Restored Same Day
Before
A homeowner in Miraflores woke up to a 58-degree house and a furnace that ran the blower but never lit. The board showed an ignition fault code, and the igniter read open on the multimeter.
After
We replaced the igniter, verified the burners lit within the manufacturer's time window, and confirmed temperature rise at 45 degrees. Total repair time was under two hours, and heat was back before noon.
Maintenance: Change the furnace filter every 60 to 90 days and schedule a fall tune-up so the igniter and flame sensor are checked before the heating season starts.
Short Cycling Fixed With Airflow Correction
Before
A San Isidro home had a furnace short cycling every four minutes. The previous company recommended a full replacement. We found a tripped limit switch caused by a clogged filter and a blower running at the wrong speed.
After
We replaced the filter, cleaned the blower wheel, and adjusted the blower speed to match the furnace's rated rise. The furnace ran full 15-minute cycles after the repair, and the homeowner avoided a $6,000 replacement.
Maintenance: Check the filter monthly during heavy-use months and have static pressure measured at your next tune-up to catch airflow problems early.
Cracked Heat Exchanger Red-Tagged Safely
Before
A landlord in San Juan de Lurigancho called about a strange smell and a furnace that kept locking out. Our inspection camera found a cracked heat exchanger, which is a carbon monoxide risk.
After
We red-tagged the furnace, shut the gas, and walked the owner through replacement options the same day. A new furnace was installed that week, and the tenant had safe, reliable heat before the next cold snap.
Maintenance: Schedule an annual heat exchanger inspection and keep a working CO detector on every floor of a rental property.
Problems we solve
Gas Furnace Problems We Solve in Lima
Most no-heat calls fall into a handful of categories. Here is what we see most in Allen County and how we fix it.
Furnace lights and then shuts off after a few seconds
You get a few minutes of warm air, then cold. This usually means the flame sensor cannot prove flame, and the board locks out to prevent a gas buildup. We pull the flame sensor, clean it with steel wool or replace it if it is out of spec, then verify microamp readings through a full cycle. Most of these repairs finish in under two hours and restore steady heat the same day.
Furnace blows cold air with the blower running
The blower moves air but the burners never light, so you are circulating cold air through the house and burning electricity for nothing. We test the igniter, gas valve, and inducer pressure switch in sequence to find where the ignition sequence breaks. A failed igniter or a weak gas valve is the usual culprit, and both are parts we carry on the truck.
Furnace short cycles every few minutes
Short cycling wears out the igniter, inducer motor, and heat exchanger, and it drives up your gas bill while leaving rooms cold. We check the filter, blower speed, limit switches, and gas manifold pressure to find the cause. Often it is restricted airflow or an oversized furnace, and we correct the airflow rather than just resetting the switch.
Furnace makes banging or screeching noises
Delayed ignition causes a small bang when gas finally lights, and a screeching blower motor is on its way to failing completely. We isolate the noise source, test the blower motor and capacitor, and check ignition timing. Replacing a failing blower motor before it seizes saves you a no-heat emergency later in the season.
Uneven heating from room to room
Upstairs stays cold while the furnace runs constantly, which points to duct or airflow problems rather than a dead furnace. We measure static pressure, check blower speed settings, and inspect duct balance. Adjusting blower speed and sealing obvious duct leaks often evens out temperatures without replacing the furnace.
Pricing and expectations
Gas Furnace Repair Pricing in Lima
$180 - $1,400 depending on the failed component and labor involved
We quote flat-rate pricing before any repair starts, so you know the number before we pick up a wrench. Typical 2026 pricing for gas furnace repair in Lima runs $180 to $450 for ignition, flame sensor, thermocouple, and limit switch work. Blower motor, inducer motor, gas valve, and control board replacements run $600 to $1,400 depending on the part and the labor involved. The diagnostic fee is quoted upfront and credited toward the repair when you approve the work. No hourly clock, no surprise line items.
A $300 flame sensor and igniter repair that restores heat is far cheaper than a $6,000 furnace replacement you did not need. We quote flat-rate, credit the diagnostic fee, and warranty our labor for 90 days.
Failed Component
A flame sensor cleaning and igniter swap is a quick, low-cost repair. A blower motor or inducer motor replacement takes three to five hours and costs more in parts and labor. We quote the exact part before starting.
Furnace Age and Brand
Older furnaces and less common brands can mean longer diagnostic time or a special-order part. We stock common Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana parts to keep same-day repairs possible.
Access and Location
A furnace in a tight closet or attic takes longer to service than one in an open basement. We factor access into the flat-rate quote so there is no surprise add-on once the tech is on site.
After-Hours or Emergency Call
Nights, weekends, and holidays carry an emergency dispatch rate. If you can wait for a same-day window during normal hours, you avoid that premium and still get heat back the same day.
Repair vs. Replace
If the heat exchanger is cracked or the furnace is past 18 years, repair may not be the right call. We give you both numbers and let you decide, with no pressure either way.

Customer stories
What Lima Customers Say
Marcus T.Homeowner, Miraflores
Furnace quit at 11 p.m. on a Friday and the house was down to 58 degrees by morning. They had a tech out by 9 a.m. Saturday, found a failed igniter, and had heat back in under two hours. Price was exactly what they quoted on the phone. No upsell, no drama.
Denise R.Homeowner, San Isidro
Our furnace was short cycling every few minutes and the last company just told us to replace it. These guys checked the limit switch and airflow, cleaned the flame sensor, and adjusted the blower speed. It has run full cycles all winter since. Saved us thousands.
Victor A.Landlord, San Juan de Lurigancho
I manage four rentals in Lima and use them for every no-heat call. They stock the common parts, so most repairs finish the same visit. Last month they fixed a Goodman blower motor in one afternoon and had the tenant warm that night. Fair pricing and they actually answer the phone.
How much does gas furnace repair cost in Lima OH?
Most repairs run $180 to $450 in 2026, covering ignition, flame sensor, thermocouple, and limit switch work. Blower motor, inducer motor, and control board replacements run $600 to $1,400. The diagnostic fee is quoted upfront, and we credit it toward the repair when you approve the work.
