Lima Furnace Repair Pros handles residential and commercial furnace work across Lima, Ohio and the surrounding Allen County towns. We repair gas, electric, and propane furnaces, from Carrier and Trane systems to older Goodman and York units nobody else wants to touch. Our techs carry a manifold gauge set, combustion analyzer, and clamp meter on every truck, so most repairs finish in one visit.
What separates us is simple: we answer the phone at 2 a.m. in January, and we tell you the price before we open the panel. We work the older housing stock around 45801 and 45805 where ductwork is tight and heat exchangers rust from decades of short cycling. If you need the best Furnace Repair in Lima, start with a company that knows these blocks.


Every furnace fails differently, so we stock parts for the brands we see most: Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana. Whether you need same day furnace repair Lima OH or a full blower motor swap, we carry igniters, flame sensors, control boards, and inducer motors on the truck. One call covers diagnosis, repair, and a heat test before we leave.

Natural gas furnaces are the standard in Lima, and most no-heat calls trace back to a failed igniter or a dirty flame sensor. We test gas pressure with a manifold gauge set, verify the thermocouple, and confirm the burners light clean before we button the panel back up.

Electric furnaces run on heating elements and sequencers that burn out quietly over time. We use a clamp meter to check amp draw on each element, replace failed sequencers, and confirm the blower moves air evenly through every room of your Lima home.

Propane systems in rural Allen County need different orifice sizing and combustion settings than natural gas. We adjust the gas valve, test with a combustion analyzer, and check the heat exchanger for cracks that propane's hotter burn tends to accelerate.

We are a local furnace repair company Lima Ohio homeowners call back because we fix the problem and explain what caused it. No upsells, no mystery invoices, no waiting three days in a cold house. Here is what you get when you call.
Furnaces quit at the worst times, so our phone line stays open overnight, on weekends, and through holidays. Most emergency calls in Lima get a tech at the door within a few hours. Call (419) 287-8289 and a real person answers.
You get the diagnosis and the price before we touch a wrench. Typical repairs run $180 to $650 depending on the part. If the fix is simple, we say so. If a heat exchanger is cracked, we show you the camera footage and lay out your options.
Our techs hold NATE certification and work under an Ohio HVAC license, with EPA Section 608 handling for refrigerant and OSHA safety compliance on every job. We follow ACCA standards for airflow and combustion, so the repair passes inspection and holds up.
Furnace repair is billed per job, not by the hour, so you know the number before we start. These are typical 2026 ranges for Lima and Allen County. Your written price depends on the failed part and how hard it is to reach.
Tell us what the furnace is doing: dead, blowing cold, short cycling, or making noise. We ask a few questions to narrow it down and give you a realistic arrival window, often within a few hours.
A tech tests the furnace with a multimeter, manifold gauge set, and combustion analyzer. We check the igniter, flame sensor, limit switch, and inducer, then show you the failed part and the price to fix it.
Once you approve the price, we replace the part with an OEM-spec component and run the furnace through a full heating cycle. We verify temperature rise, airflow, and combustion before we call it done.
We show you what failed and why, change your filter if it's due, and register the part warranty. You get a clean work area and a furnace that holds temperature through the night.
You call, we show up, we find the fault, and we fix it. No runaround and no vague timelines. Here is exactly what happens from the first ring to the moment your house is warm again.

Most no-heat calls in Lima come down to a handful of failures. We see them every winter and carry the parts to fix them the same day, so you are not waiting on a special order while the house cools down.
We check the breaker, door switch, thermostat, and control board in order. A dead board or tripped safety is usually the cause. We replace the failed part and confirm ignition before we leave, often within a two-hour visit.
Cold air means the blower runs but the burners never light. We test the igniter, flame sensor, and gas valve, then replace the failed component. Most of these calls trace back to a dirty flame sensor that shuts the furnace down seconds after ignition.
Short cycling burns out igniters and inducer motors and stresses the heat exchanger. We measure temperature rise and static pressure, check the filter and limit switch, and correct the airflow or replace the failing safety so the furnace runs full cycles again.
A screech is usually the blower motor bearing, and a boom points to delayed ignition from a weak igniter. We identify the noise source, replace the worn part, and test the furnace through several cycles so the sound is gone for good.

Real calls, real winters, real fixes. These are a few of the jobs we have run around Lima and Allen County, in the customers' own words.
Our furnace died on a Friday night in January with the house at 58 degrees. They had a tech out by 10 p.m., found a failed igniter, and had heat back before midnight. The price he quoted on the phone was the price we paid.
I called three companies and these guys were the only ones who would come out the same day. Turned out to be a dirty flame sensor, not the control board another shop told me I needed. Honest work and half the price I expected.
Our Bryant furnace was short cycling all winter and nobody could figure out why. They measured the airflow, found the return was undersized, and fixed it. Two winters later it still runs full cycles. Worth every dollar.

Most repairs run $180 to $650 in 2026, depending on the part. A flame sensor clean or igniter swap sits at the low end. A blower motor, control board, or gas valve lands in the middle. Heat exchanger work or a full replacement starts around $850 and goes up from there. We quote the price before we start.
The best furnace repair company in Lima Ohio is the one that answers at 2 a.m., carries the part on the truck, and quotes the price before starting. Ask whether the techs hold NATE certification and an Ohio HVAC license. We do, and we have the local experience to back it up on every brand from Carrier to York.
Yes. We run emergency furnace repair Lima OH 24/7, including weekends and holidays. Call (419) 287-8289 and a real person picks up. Most emergency calls in Lima and Allen County get a tech on site within a few hours, and our trucks carry common igniters, flame sensors, and blower motors so most fixes finish on the first trip.
Check three things: a current Ohio HVAC license, NATE certification, and whether they quote a price before starting work. Ask what brands they stock parts for and whether the repair carries a warranty. A pro who tests with a combustion analyzer and shows you the failed part is doing it right.
Repair usually wins if the furnace is under 15 years old and the heat exchanger is sound. Replacement makes more sense when the exchanger is cracked, repairs pass $1,500, or you are calling us twice a winter. We inspect with a camera and give you both numbers so the choice is yours.
