What is included
What our Lennox Furnace Repair in Lima includes
Every Lennox furnace repair call includes a full diagnostic, a written quote, the repair itself, and a post-repair test. We check the whole system, not just the part that failed, because a dirty filter or a weak blower motor can take out a new igniter in a month.
Full ignition system test
We test the igniter, flame sensor, and control board with a multimeter and flame sensor tester. If the igniter is not drawing the right current or the flame signal is weak, we replace the failed part. This is where most Lennox no-heat calls end.
Gas pressure verification
We check inlet and outlet gas pressure with a manifold gauge set and verify combustion with a combustion analyzer. Correct gas pressure protects the heat exchanger and keeps the furnace running at the efficiency it was designed for.
Blower and airflow check
We test the blower motor with a clamp meter, inspect the capacitor, and check the filter. Restricted airflow is the number one cause of limit switch trips and short cycling. We fix the airflow problem, not just the switch.
Heat exchanger inspection
We inspect the heat exchanger with an inspection camera and show you the footage. A cracked exchanger is a carbon monoxide risk and needs to be addressed before the furnace runs again. You see what we see.
Post-repair temperature test
After the repair, we run two full heating cycles and measure the temperature rise at the supply and return. You see the numbers before we leave. If the rise is outside the manufacturer's range, we keep working until it is right.

Service overview
What Lennox Furnace Repair in Lima actually involves
Lennox Furnace Repair in Lima is the diagnostic and mechanical work required to restore heat to a Lennox gas, electric, or propane furnace that has stopped running, is short cycling, or is blowing cold air. Our technicians test the ignition system, flame sensor, control board, blower motor, inducer motor, gas valve, and heat exchanger in sequence, then repair or replace the failed component. Most single-part repairs take two to four hours from arrival to a verified temperature rise.
Lima winters regularly push into the single digits, and furnaces here run hard from October through April. That constant cycling wears out igniters, thermocouples, and limit switches faster than in milder climates. If your Lennox furnace is not turning on or keeps tripping the limit switch, call us before the next cold front. We offer affordable Lennox furnace repair Lima Ohio homeowners can schedule without waiting days for a callback.
- Same-day heat restoration — Most Lennox furnace repair calls in Lima are diagnosed and repaired the same day. We carry igniters, flame sensors, thermocouples, and control boards on every truck, so you are not waiting two days for a part to ship while your house drops below 60 degrees.
- Code-correct workmanship — Every repair follows ACCA standards and Ohio HVAC license requirements. We test gas pressure with a manifold gauge set and verify combustion with a combustion analyzer before we leave. That protects your family and keeps your Lennox warranty intact.
- Upfront pricing, no surprises — You get a flat repair price before we start. Typical 2026 Lennox furnace repair cost Lima OH ranges from $180 to $650 depending on the failed part. No hourly creep, no diagnostic fee stacked on top of the repair, no pressure to replace a furnace you can fix.
- Emergency availability — Furnaces fail at the worst times. We run emergency Lennox furnace repair Lima OH calls nights and weekends because a 15-degree night in Allen County is not a wait-until-Monday problem. Call (419) 287-8289 and we will dispatch the nearest tech.
- Local parts inventory — Our trucks carry the Lennox parts that fail most in this climate: igniters, flame sensors, thermocouples, limit switches, and blower motors. That means same-day Lennox furnace repair Lima instead of a two-day wait for a shipped part while your house freezes.
- Diagnostic accuracy — We use a multimeter, clamp meter, and combustion analyzer on every call. That is how we tell a failed igniter from a dirty flame sensor from a bad control board. Guessing costs you money. Testing gets it right the first time.
- Emergency response — Lennox heating repair Lima calls do not wait for business hours. We run 24/7 emergency dispatch because a furnace failure at 2 a.m. in January is a real emergency. Call (419) 287-8289 and we will get a tech headed your way.
- Warranty-backed repairs — Every repair we make is backed by a written warranty on parts and labor. If the same component fails again within the warranty window, we come back and make it right. That is how we have built our reputation across Allen County.
The service timeline
How our Lennox furnace repair process works
Phone triage
When you call (419) 287-8289, we ask what your Lennox furnace is doing: not turning on, blowing cold air, short cycling, or making strange noises. That five-minute conversation tells us which parts to load on the truck and whether this is a same-day or emergency call.
On-site diagnosis
A NATE-certified tech arrives and runs a full diagnostic: multimeter on the control board, clamp meter on the blower motor, flame sensor tester on the ignition circuit. We check the filter, the inducer motor, and the limit switch before we quote anything. Diagnosis takes 30 to 45 minutes.
Written repair quote
You get the failed part, the repair price, and the expected outcome in plain language. If the heat exchanger is cracked, we show you the inspection camera footage. You approve the work before we touch a wrench.
Repair and test
We replace the failed component, whether that is an igniter, a gas valve, a blower motor, or a control board. After reassembly we run the furnace through two full heating cycles and measure the temperature rise at the supply and return. You see the numbers before we pack up.
Walkthrough and filter check
Before we leave, we walk you through what failed and why, show you the old part, and check your furnace filter. If a dirty filter contributed to the failure, we tell you the right size and change interval. Most visits wrap in under three hours.

Tools and methods we use on Lennox furnaces
Manifold gauge set
Measures inlet and outlet gas pressure on Lennox gas valves. Correct pressure protects the heat exchanger and keeps combustion within spec.
Multimeter
Tests control board voltage, igniter current draw, and flame sensor microamps. This is how we tell a failed igniter from a dirty flame sensor.
Combustion analyzer
Verifies carbon monoxide levels and combustion efficiency after every gas furnace repair. We do not call a job done until the numbers are safe.
Clamp meter
Measures blower motor and inducer motor current draw. High amps point to failing bearings or a bad capacitor.
Inspection camera
Lets us see inside the heat exchanger without disassembling the furnace. We show you the footage if we find a crack.
Flame sensor tester
Confirms the flame signal strength at the control board. A weak signal is the most common cause of a furnace that lights and then shuts off.
Blower motor puller
Removes the blower assembly without damaging the housing or the wheel. This keeps the repair clean and the airflow correct after reassembly.
Sequence-of-operation diagnosis
We follow the furnace through its full startup sequence: call for heat, inducer motor, pressure switch, igniter, gas valve, flame sensor, blower motor. The first step that fails is the problem. This method eliminates guesswork and repeat visits.
Combustion analysis after repair
Every gas furnace repair ends with a combustion analyzer test. We check carbon monoxide, oxygen, and stack temperature. If the numbers are off, we adjust the gas valve or air shutter until they are right.
Temperature rise verification
We measure supply and return air temperature after two full heating cycles. The rise must fall within the range on the furnace data plate. If it does not, we check the blower speed and the duct static pressure.
ACCA standards compliance
Our repairs follow ACCA standards for airflow, combustion, and venting. That keeps your Lennox furnace running at its rated efficiency and protects your manufacturer warranty.
Where this service helps
When Lima homeowners call us for Lennox repair
Your Lennox furnace quits on the first cold night of October and the house is dropping fast.
We treat no-heat calls as priority dispatch. A tech arrives with igniters, flame sensors, and control boards on the truck. We diagnose the failure, quote the repair, and fix it the same visit in most cases. Heat restored the same day, usually within three hours of your call. You get the failed part in hand and a written warranty on the repair.
Your Lennox furnace runs but the house never gets warm, and some rooms stay cold.
We test the blower motor with a clamp meter, check the capacitor, and measure the temperature rise at each register. Weak airflow is usually a blower motor or duct issue. We repair the cause, not the symptom. Even heating across the house and a furnace that runs at the temperature rise the manufacturer specified. Most uneven-heating calls are resolved in one visit.
Your Lennox furnace is 12 years old, short cycling, and you are not sure whether to repair or replace.
We diagnose the failed part, quote the repair, and give you the honest math: repair cost versus remaining life. If the heat exchanger is cracked, we show you the footage and explain why replacement is the safer call. A clear decision with real numbers, not a sales pitch. Most customers repair if the exchanger is sound and replace if it is not.
You manage rental property in Allen County and a tenant calls with no heat on a Sunday.
We run 24/7 emergency dispatch for property managers and landlords. We diagnose the Lennox furnace, repair it, and send you the invoice with the failed part documented. Your tenant gets heat and you get a record. Tenant heat restored the same day, documented repair, and a warranty that covers the part and our labor. No repeat calls on the same failure.
Local execution
How Lennox Furnace Repair runs in Lima, Ohio
Lima sits in a climate that swings hard: 90-degree summers and single-digit winters with wind chills that push furnaces to their limit. That swing is why Lennox furnaces here fail differently than in milder markets. Igniters and flame sensors wear out faster because the furnace cycles more. Heat exchangers see wider thermal stress. And older housing stock in Cercado de Lima and Breña often has undersized return ducts, which causes limit switch trips and short cycling. We adjust our diagnostic sequence for those conditions. If you need Lennox heating repair Lima homeowners trust, we test airflow and temperature rise on every call, not just the part that failed. We also stock the Honeywell and White-Rodgers controls that Lennox uses, so most repairs are finished the same day. For emergency Lennox furnace repair Lima OH calls, we dispatch 24/7 across Allen County.
Cercado de Lima
Older homes with original ductwork and undersized returns. Limit switch trips and short cycling are common here. We check static pressure on every call.
San Miguel
Mix of mid-century homes and newer builds. Furnaces here often run on propane, which needs different gas valve settings than natural gas. We adjust accordingly.
Surquillo
Dense residential blocks with a lot of rental property. We handle a high volume of same-day no-heat calls for landlords and tenants in this area.
Chorrillos
Coastal humidity can corrode burner assemblies and flame sensors faster. We inspect the burner compartment and clean the flame sensor on every visit.
Wide seasonal temperature swings from summer to winter
Furnaces cycle more, which wears out igniters, thermocouples, and limit switches faster. We stock those parts on every truck so repairs are same-day.
Older housing stock with undersized return ducts
Restricted return air causes limit switch trips and short cycling. We measure static pressure and temperature rise, then fix the airflow problem, not just the switch.
Propane furnaces in rural Allen County
Propane needs different gas valve pressure settings than natural gas. We set the manifold pressure with a gauge and verify combustion with an analyzer on every propane call.

Before and after
What a successful service visit changes.
No-heat Lennox furnace restored in Cercado de Lima
Before
A homeowner called at 7 a.m. with a Lennox furnace that would not light. The house was at 58 degrees and dropping. The furnace clicked but never fired. The homeowner had already replaced the thermostat with no result.
After
We diagnosed a failed igniter drawing zero current. Replaced it, cleaned the flame sensor, and verified the flame signal. Temperature rise measured 45 degrees, within spec. Heat restored by 9:30 a.m. Total repair: $240.
Maintenance: Change the furnace filter every 60 days during heating season. A dirty filter restricts airflow and shortens igniter life. We left a spare filter and the correct size on the invoice.
Short cycling fixed in San Miguel rental unit
Before
A landlord called about a Lennox furnace short cycling every eight minutes. Tenants complained the house never got warm. Two previous techs had replaced the limit switch twice without solving the problem.
After
We tested the blower motor with a clamp meter and found it drawing high amps. The motor was failing, reducing airflow and tripping the limit switch. Replaced the blower motor and capacitor. Temperature rise now 42 degrees, even across all rooms.
Maintenance: We set the blower speed to match the duct system and recommended a duct cleaning. The landlord scheduled it for the following week. No short cycling calls since.
Cracked heat exchanger diagnosed in Surquillo
Before
A homeowner noticed a metallic smell and a headache after running the Lennox furnace. The furnace was 14 years old and had never been inspected. The home had a carbon monoxide alarm that had not triggered.
After
Our inspection camera found a 2-inch crack in the heat exchanger. We shut the furnace down, showed the homeowner the footage, and explained that repair was not safe. The furnace was replaced the next day. No CO exposure.
Maintenance: Annual heat exchanger inspections catch cracks before they become a health risk. We recommend a combustion analysis every fall, especially on furnaces over 10 years old.
Problems we solve
Lennox furnace problems we solve in Lima
Most Lennox furnace failures in Lima trace back to one of a handful of parts. We diagnose the actual cause instead of guessing, and we stock the parts that fail most so you are not waiting on a shipment.
Lennox furnace not turning on
A no-heat call in January drops your house below 60 degrees within hours. Pipes can freeze, and the repair cost climbs if the problem cascades into a cracked heat exchanger. We test the ignition sequence from the control board through the igniter and flame sensor. Most no-heat calls are a failed igniter or a dirty flame sensor. We replace the part, verify the flame signal, and run two heating cycles before we leave.
Lennox furnace blowing cold air
Cold air from the registers means the furnace is lighting and then shutting off within seconds. That is usually a flame sensor or gas valve issue, and it will not fix itself. We test the flame signal with a multimeter and check gas pressure with a manifold gauge set. If the sensor is coated, we clean it. If the gas valve is sticking, we replace it. Most cold-air calls are fixed in under two hours.
Lennox furnace short cycling
Short cycling wears out the igniter, the blower motor, and the control board faster. It also raises your gas bill because the furnace never reaches steady-state efficiency. We check the filter, test the limit switch, and measure the blower motor current with a clamp meter. Restricted airflow is the usual cause. We fix the airflow restriction and replace the limit switch if it has failed. Same-day repair.
Lennox furnace making strange noises
Squealing, banging, and rumbling point to failing bearings, a loose gas valve, or a cracked heat exchanger. Ignoring the noise usually turns a $300 repair into a $3,000 replacement. We diagnose the noise source: blower motor bearings, inducer motor, or gas valve. We replace the failed component and test the furnace through two cycles. If the heat exchanger is cracked, we show you the camera footage and explain your options.
Pricing and expectations
Lennox Furnace Repair cost in Lima
$180 - $650 depending on the failed part and whether the call is emergency or scheduled
Typical 2026 Lennox furnace repair cost Lima OH runs $180 to $650 for a single-part repair, with most calls landing between $220 and $420. The price depends on the failed part, the furnace model, and whether the repair is during business hours or an emergency call. We quote the full repair price before we start, so you are never surprised. If the repair is not worth it, we tell you and give you the honest math on replacement.
A $300 repair on a furnace with five years of life left beats a $4,000 replacement every time. We give you the honest math and let you decide. No pressure, no upsell.
Failed component
A flame sensor or igniter replacement sits at the low end, around $180 to $280. A blower motor, inducer motor, or control board pushes toward $400 to $650. The part cost and labor time both scale with complexity.
Furnace model and age
Newer Lennox furnaces with variable-speed blowers and communicating control boards take longer to diagnose and cost more to repair. Older single-stage furnaces are simpler and faster.
Emergency vs. scheduled
After-hours, weekend, and holiday calls carry a trip charge. Scheduled same-day repairs during business hours do not. We tell you the difference on the phone before we dispatch.
Access and location
A furnace in a tight closet or attic takes longer to access than one in a basement. We quote based on the actual job, not a flat rate that does not fit your house.
Warranty coverage
If the failed part is still under Lennox manufacturer warranty, you pay labor only. We check your model and serial number before quoting. Our labor carries its own written warranty.

Customer stories
What Lima homeowners say about our Lennox repairs
Marcus T.Homeowner, Cercado de Lima
My Lennox furnace quit on a Friday night in January. I called at 9 p.m. and a tech was at my door by 10:30. He tested the flame sensor with a multimeter, showed me it was coated, cleaned it, and had heat back on in 20 minutes. Charged me the quoted price, no after-hours surprise. I have his number saved now.
Elena R.Homeowner, San Miguel
Our Lennox was short cycling every 10 minutes and the house never got warm. The tech found a dirty filter and a weak blower motor. He replaced the motor, checked the temperature rise at every register, and showed me the numbers. Two hours total. The house heats evenly now for the first time in two winters.
David K.Property Manager, Surquillo
I manage six rental units with Lennox furnaces, and I need a crew that shows up when they say they will. These guys have done four repairs for me this year, all same-day. They quote before they start, they clean up, and they explain the failed part to my tenants. That is rare in this trade.
