Furnace runs but only blows cold air
We test the flame sensor, gas valve, and limit switch to find why the burners aren't lighting or staying lit. Most cold-air calls are a dirty flame sensor or a stuck gas valve, and we fix both the same visit.

About this service
Furnace Not Heating Repair Ashland OH: What It Actually Involves
Furnace not heating repair Ashland OH is the diagnostic and mechanical service that restores heat when a furnace runs but never warms the house, or won't fire at all. We test the thermostat call, verify gas pressure with a manometer, check the igniter and flame sensor, and trace the fault through the control board, pressure switch, and limit switch. Most no-heat calls trace back to one of five parts: thermocouple, flame sensor, igniter, inducer motor, or gas valve.
In Ashland, no-heat calls spike from October through March, when overnight lows drop into the teens and single digits. Older homes near Historic Ashland and the University District often run 15- to 25-year-old Carrier, Trane, and Lennox furnaces that short cycle or blow cold air. If your furnace is not working in Ashland Ohio, we treat it as urgent - a frozen pipe repair costs far more than a flame sensor cleaning.

What's included
What Our Furnace Not Heating Repair Includes
Every no-heat call includes a full diagnostic, a written price before work begins, the repair itself, and a safety check before we leave. Parts are billed at flat-rate pricing, and we warranty our labor for one year.
✓
Full No-Heat Diagnostic
We test the thermostat call, control board voltage, gas pressure, igniter, flame sensor, inducer motor, pressure switch, and limit switch. This 30- to 45-minute diagnostic tells us exactly which component failed instead of guessing.
✓
Written Repair Price
You get the repair cost in writing before we start. Common no-heat fixes run $180 to $450; larger parts like control boards and blower motors run $450 to $900 installed. No hourly surprises, no padded time.
✓
Failed Part Replacement
We replace the failed thermocouple, flame sensor, igniter, pressure switch, control board, blower motor, inducer motor, gas valve, or capacitor with an OEM or equivalent part. Most repairs finish in one visit.
✓
Heat Cycle Verification
After the repair, we run the furnace through a full heat cycle and measure temperature rise at the supply and return. We confirm the limit switch, pressure switch, and flame rectification are all behaving before we call it done.
✓
Carbon Monoxide Safety Check
We test the flue and the air around the heat exchanger with a combustion analyzer on every no-heat call. If we find a CO leak or a cracked heat exchanger, we red-tag the furnace and explain your options.
✓
One-Year Labor Warranty
Our repair labor is warrantied for one year, and parts carry the manufacturer's warranty. If the same component fails inside that window, we come back and fix it at no charge. We document the repair for your records.
How it works
How Our No-Heat Repair Process Works
01
Call And Triage
You call and describe the symptoms - no heat, cold air, short cycling, or a furnace that won't fire. We ask about the brand, age, and thermostat, then dispatch the nearest tech. Most Ashland calls get a 60- to 90-minute arrival window, and emergency calls after 10 p.m. get priority dispatch.
02
Full Diagnostic
The tech tests the thermostat call, checks voltage at the control board with a multimeter, reads gas pressure with a manometer, and inspects the igniter, flame sensor, and inducer motor. This 30- to 45-minute diagnostic pinpoints the failed component instead of guessing at parts.
03
Written Estimate
You get a clear price for the repair before any work begins. If the furnace needs a thermocouple, flame sensor, or pressure switch, the number is usually $180 to $450. If it needs a control board, blower motor, or inducer motor, expect $450 to $900 installed.
04
Repair And Test
We replace the failed part, then run the furnace through a full heat cycle. The tech checks temperature rise at the supply and return, verifies flame rectification, and confirms the limit switch and pressure switch are behaving. Most repairs take 1 to 3 hours from arrival to heat.
05
Safety And CO Check
Before we leave, we run a combustion analyzer on the flue and check for carbon monoxide around the heat exchanger. If we find a cracked heat exchanger or a CO leak, we red-tag the furnace and walk you through options. Safety comes before the invoice.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Manometer
Measures gas pressure at the valve and pressure switch to confirm the furnace is getting the gas pressure it needs to fire and stay lit.
Multimeter
Tests voltage and continuity at the thermostat, control board, transformer, and every safety switch to isolate the failed component.
Combustion Analyzer
Reads flue gases and carbon monoxide levels to verify safe combustion and catch a cracked heat exchanger before it becomes a health risk.
Thermocouple Tester
Checks millivolt output on standing-pilot furnaces to confirm whether the thermocouple is worn and needs replacement.
Flame Sensor Tester
Verifies flame rectification microamps so we know the sensor is reading the flame correctly and not shutting the furnace down.
Clamp Meter
Measures amp draw on blower and inducer motors and tests capacitors to catch a failing motor before it quits entirely.
Inspection Camera
Lets us look inside the heat exchanger and flue for cracks, blockages, or debris without tearing the furnace apart.
Real results
Before and after.
Inducer Motor Failure in Willow Creek
Before
A high-efficiency Rheem furnace wouldn't fire. The pressure switch never closed, so the ignition sequence stopped every time. The house was at 58 degrees and dropping overnight.
After
We replaced the inducer motor, cleared a partially blocked condensate drain, and verified pressure switch operation with a manometer. Heat was back in 2.5 hours, and the furnace held temperature rise within spec.
Dirty Flame Sensor in South Ashland
Before
A Goodman furnace fired for 8 to 10 seconds, then shut off. The homeowner had already replaced the thermostat with no luck. The house never got above 62 degrees.
After
We cleaned the flame sensor, verified flame rectification microamps, and checked gas pressure. The repair took 45 minutes and cost $190. The furnace ran full cycles and held 70 degrees.
Cracked Heat Exchanger in Historic Ashland
Before
A 22-year-old Carrier furnace short cycled and gave off a faint burning smell. A CO alarm in the hallway had gone off twice. The homeowner was ready to repair it, but the unit was unsafe.
After
Our inspection camera found a cracked heat exchanger. We red-tagged the furnace, explained the CO risk, and helped the homeowner choose a replacement. New furnace was installed and heating within two days.
Problems we solve
No-Heat Problems We Solve in Ashland
Most furnace not heating up in Ashland County calls trace back to one of a handful of failed components. Here are the ones we see most, and what happens if you let them ride.
Ask a pro →↗
Furnace short cycles every few minutes
We check airflow, the filter, the limit switch, and gas pressure with a manometer. A clogged filter or a failing limit switch is usually the culprit, and correcting it stops the cycling and restores steady heat.
Pilot light won't stay lit
We test the thermocouple with a thermocouple tester and check the pilot orifice. A worn thermocouple is the usual cause, and replacing it takes under an hour and gets the pilot holding steady.
Furnace won't fire at all
We trace the ignition sequence from the thermostat to the control board, igniter, and gas valve. Whether it's a failed igniter, a bad control board, or a stuck pressure switch, we identify it and repair it on the spot.

What Ashland Homeowners Say
★★★★★
“Our 22-year-old Carrier quit on a Friday night in January. The house was at 54 degrees by morning. They had a tech out by 9 a.m., found a failed inducer motor, and had heat back by noon. Price was exactly what they quoted on the phone. No runaround, no upsell.”

★★★★★
“Furnace was firing for 10 seconds then shutting off. Turned out to be a dirty flame sensor. Tech cleaned it, tested the whole system, and charged me $190. He also showed me the filter was the wrong size and swapped it. Honest work, fair price.”
MT
Marcus T.Homeowner, South Ashland
✓ Verified★★★★★
“We rent out a duplex near the university and the furnace stopped heating over winter break. They came out same day, replaced a pressure switch, and had both units running before the students came back. I've used them three times now for different properties.”
KL
Karen L.Homeowner, Ashland University District
✓ VerifiedThe most common causes are a dirty or failed flame sensor, a bad igniter, a stuck pressure switch, or a tripped limit switch. In Ashland's older housing stock, we also see cracked heat exchangers and failed inducer motors on furnaces over 15 years old. A 30-minute diagnostic with a multimeter and manometer pinpoints which one it is.
Typical 2026 pricing in Ashland runs $180 to $450 for common repairs like a thermocouple, flame sensor, or igniter, and $450 to $900 for a control board, blower motor, or inducer motor. Emergency after-hours calls add a dispatch fee. You get the exact number in writing before we start the repair.
