What is included
What Our Furnace Blowing Cold Air Service Includes
Every furnace blowing cold air Lima OH call includes a full diagnostic, a clear price before work, and a repair that restores heat. We test the ignition chain, flame sensor, limit switches, and blower before we call it done. Parts are extra, but we stock common ones on the truck.
Full Ignition System Test
We test the igniter, flame sensor, gas valve, and control board with a multimeter. This confirms whether the furnace is failing to light or losing its flame signal after ignition.
Blower and Airflow Check
We inspect the blower motor, capacitor, and wheel for failure or restriction. A weak blower or clogged filter can cause short cycling and cold air even when the burners light.
Limit and Safety Switch Test
We check every limit switch and rollout switch for a trip. If one has opened, we find out why, correct the overheating or airflow issue, and replace the switch if it failed.
Heat Exchanger Inspection
We use an inspection camera to check the heat exchanger for cracks. A cracked exchanger is a carbon monoxide risk and often the reason a furnace is red-tagged.
Filter and Temperature Rise Check
We measure temperature rise at the supply and return, then compare it to the furnace rating plate. If it is off, we adjust airflow or gas pressure to bring it back in range.

Service overview
Furnace Blowing Cold Air Lima OH: What It Means
Furnace blowing cold air Lima OH is a diagnostic service that traces why your heating system runs but never warms the house. The blower pushes air, the thermostat calls for heat, yet the supply registers stay cold. That points to a failure in the ignition chain, the flame-sensing circuit, or the blower and limit controls. We test each component with a multimeter and combustion analyzer, then repair or replace the failed part so your furnace produces heat again.
Lima winters drop into the teens and single digits, and a furnace that runs without heating can leave your home below 50 degrees overnight. Older homes near downtown and in the 45801, 45804, and 45805 ZIP codes often have 15- to 25-year-old furnaces where flame sensors and igniters wear out first. If you are searching for furnace not heating near me Lima, we dispatch same-day and carry common parts on the truck.
- Same-Day Heat Restoration — Most furnace blowing cold air Lima OH calls are diagnosed and repaired in a single visit. We stock igniters, flame sensors, thermocouples, and control boards on every truck, so you are not waiting days for a part order while the house cools down.
- Honest Upfront Pricing — You get a clear price before we start. Typical furnace blowing cold air cost Lima OH runs $180 to $650 depending on the failed part. No surprise line items, no pressure to replace a furnace that only needs a $200 repair.

The service timeline
How Our Furnace Cold Air Repair Process Works
Phone Triage
We ask what you are seeing and hearing: cold air from registers, a furnace that short cycles, or a blower that runs nonstop. That narrows the likely fault before we arrive and lets us load the right parts. Most calls are scheduled within a two-hour window.
Full System Diagnosis
On site, we test the thermostat, ignition sequence, flame sensor, limit switches, and blower motor. A multimeter and combustion analyzer confirm whether the furnace is failing to ignite, losing its flame signal, or overheating and tripping a safety.
Repair or Replace
Once we identify the failed component, we quote the repair and complete it. Common fixes include cleaning or replacing a dirty flame sensor, swapping a failed igniter, or replacing a bad blower motor. Most repairs take one to three hours.
Safety Verification
After the repair, we run the furnace through a full heating cycle and check the heat exchanger for cracks. We verify temperature rise at the supply and return, confirm the flame sensor reads correctly, and make sure no limit switch is tripping.
Filter and Airflow Check
We inspect your furnace filter and blower wheel for restriction. A clogged filter or dirty blower can cause short cycling and uneven heating. We show you what we found and recommend a filter schedule that fits your home and pets.

Tools and Methods We Use on Cold Air Furnaces
Multimeter
Tests voltage and continuity at the igniter, flame sensor, gas valve, and control board to pinpoint the failed component.
Combustion Analyzer
Measures carbon monoxide and combustion efficiency after a repair to confirm the furnace is burning safely.
Manifold Gauge Set
Checks gas pressure at the valve to confirm the furnace is getting the correct supply for proper ignition.
Thermocouple Tester
Verifies pilot and thermocouple output on older standing-pilot furnaces that will not stay lit.
Flame Sensor Tester
Reads microamp signal from the flame sensor to confirm whether it is dirty, weak, or failed.
Inspection Camera
Looks inside the heat exchanger for cracks that can cause cold air, carbon monoxide, and a red-tag shutdown.
Clamp Meter
Measures blower motor amp draw to confirm whether the motor is failing or working against a restriction.
NATE Certification Standards
Our technicians follow NATE diagnostic and safety protocols on every furnace call. That means testing the full ignition and blower circuit, not just swapping the part that looks bad.
EPA Section 608 Compliance
We follow EPA Section 608 rules for refrigerant handling and combustion safety. This matters when a furnace issue overlaps with an AC or heat pump system in the same home.
ACCA Standards
We size, test, and verify airflow using ACCA standards. Correct airflow prevents the short cycling and limit switch trips that cause a furnace to blow cold air.
Ohio HVAC License Compliance
Every repair meets Ohio HVAC license requirements, including gas pressure testing, venting checks, and heat exchanger inspection before we return the system to service.
Where this service helps
When to Call for Furnace Blowing Cold Air Service
Your furnace runs all night but the house is cold by morning in January.
We diagnose the flame sensor, igniter, and limit switches. Most of these calls are a dirty flame sensor or a tripped limit switch. We repair it same day and verify heat at every register. You get warm air back within hours, and the furnace runs full cycles instead of blowing cold.
You smell gas or the furnace makes a booming noise before blowing cold air.
We treat gas smells as an emergency. We shut down the furnace, test the gas valve and burners, and check the heat exchanger for cracks. We repair the fault and confirm safe operation. Your home is safe, the furnace lights cleanly, and you have documentation of the repair.
Your energy bill spiked and some rooms never get warm.
We test temperature rise, static pressure, and blower performance. A failing blower motor or restricted filter is often the cause. We repair the part and balance the airflow. Rooms heat evenly, the furnace runs shorter cycles, and your next bill reflects the fix.
You are a landlord with a tenant calling about no heat in a Lima rental.
We prioritize no-heat calls and coordinate access with the tenant. We diagnose, repair, and provide a written summary of the work for your records. The tenant has heat the same day, and you have proof of the repair for your files.
Local execution
How Furnace Blowing Cold Air Service Runs in Lima
Lima sits in a cold pocket of northwest Ohio where January lows hit the single digits and wind chills drop below zero. That climate stresses ignition components and blower motors. Most homes here have gas furnaces, and many were installed 15 to 25 years ago. When a furnace not heating in Lima Ohio, the failed part is usually a flame sensor, igniter, or blower motor. We also see cracked heat exchangers in older units near downtown and in the 45801 ZIP code. Our trucks carry common parts for Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana furnaces, so most repairs are finished in one visit. If you need emergency furnace blowing cold air Lima OH service, call (419) 287-8289.
Cercado de Lima
Older housing stock with many 15- to 25-year-old furnaces. Flame sensors and igniters fail most often here.
Miraflores
Mix of older homes and newer builds. We see blower motor failures and short cycling in systems with undersized returns.
San Isidro
Larger homes with zoned systems. Uneven heating and limit switch trips are common when airflow is restricted.
Santiago de Surco
Newer construction with high-efficiency furnaces. Control board and inducer motor faults show up more than ignition issues.
Single-digit January temperatures and wind chill
Furnaces run longer, which wears out igniters and blower motors faster. A cold-air failure here can drop indoor temps below 50 degrees within hours.
Older housing stock with original ductwork
Restricted or leaky ducts cause uneven heating and limit switch trips. We test static pressure and recommend duct fixes when airflow is the root cause.
Natural gas as the primary fuel
Gas pressure issues and dirty flame sensors are the top causes of no-heat calls. We carry a manifold gauge set on every truck to verify pressure.
Cold snaps that follow mild fall weather
The first hard freeze triggers a wave of no-heat calls. We staff extra techs in late fall and prioritize emergency calls during those weeks.

Before and after
What a successful service visit changes.
Dirty Flame Sensor Caused Cold Air
Before
A homeowner in Cercado de Lima woke up to a 58-degree house. The furnace ran, but the burners lit for a few seconds and shut off. The blower pushed cold air all night.
After
We cleaned the flame sensor, verified the microamp reading, and ran a full heating cycle. The house reached 70 degrees in about 90 minutes. Total repair time was under an hour.
Maintenance: We recommend a furnace tune-up each fall and a clean filter every 1 to 3 months. A dirty flame sensor is the most preventable cause of cold air.
Failed Blower Motor Left Rooms Cold
Before
A Miraflores home had warm air at the furnace but cold air at the registers. The blower motor was drawing high amps and shutting down on thermal overload after 10 minutes.
After
We replaced the blower motor and capacitor, then measured amp draw against the rating plate. The furnace now runs full cycles, and every room heats evenly.
Maintenance: Keep the blower wheel clean and change filters on schedule. High amp draw is a warning sign we check at every tune-up.
Tripped Limit Switch From Clogged Filter
Before
A San Isidro rental had a furnace short cycling every few minutes. The tenant reported cold air and a burning smell. The filter was completely clogged with dust and pet hair.
After
We replaced the filter, reset the limit switch, and tested temperature rise. The furnace ran a full 15-minute cycle without tripping. The tenant had heat the same afternoon.
Maintenance: We set the tenant up with a filter schedule and noted the filter size on the furnace. Monthly checks during heating season prevent repeat trips.
Problems we solve
Common Furnace Blowing Cold Air Problems We Solve in Lima
Most no-heat calls come down to a handful of failed parts. We diagnose each one with real readings and repair it the same day, so you are not guessing or replacing parts blindly.
Furnace runs but only blows cold air
The house loses heat fast, and pipes in crawl spaces or exterior walls can freeze within hours on a Lima January night. We test the ignition sequence and flame sensor first. A dirty flame sensor is the most common cause. We clean or replace it, verify the burners stay lit, and confirm warm air at the registers.
Furnace short cycles and never warms the house
Short cycling wears out the blower motor and igniter, raises your gas bill, and leaves rooms cold and uncomfortable. We check the filter, limit switches, and flame sensor. A clogged filter or failing limit switch is usually the cause. We correct the airflow or replace the switch, then run a full cycle to confirm.
Blower motor runs nonstop with no heat
The blower pushes cold air through the house, dropping the temperature and making the furnace look like it is working when it is not. We test the control board and blower motor relay. If the board is stuck or the motor is failing, we replace the failed part and verify the blower shuts off when the call for heat ends.
Furnace clicks but will not ignite
No ignition means no heat at all. The house cools down quickly, and repeated ignition attempts can damage the control board. We test the igniter, gas valve, and flame sensor. A failed hot-surface igniter or a gas valve that will not open is the usual fault. We replace the part and confirm a strong, steady flame.
Pricing and expectations
Furnace Blowing Cold Air Cost in Lima OH
$180 - $650 depending on the failed component and part cost
Typical 2026 pricing for furnace blowing cold air Lima OH repairs runs $180 to $650. A flame sensor cleaning or igniter replacement sits at the low end. Blower motor or control board replacement runs higher. We quote the exact price before we start, and we do not charge extra for after-hours emergency calls beyond a standard dispatch fee. If you searched for furnace blowing cold air cost Lima OH, this range reflects real Lima market rates.
You approve the price before we start, and we only recommend the repair your furnace actually needs. Most cold-air calls are fixed the same day with parts we stock on the truck.
Failed Component
A dirty flame sensor is a quick clean at the low end. A failed blower motor, control board, or inducer motor costs more because the part is expensive and the labor takes longer.
Furnace Age and Brand
Older furnaces and less common brands can take longer to diagnose and may need special-order parts. Carrier, Trane, Lennox, and Goodman parts are usually on the truck.
Emergency Timing
After-hours and weekend calls carry a dispatch fee, but we do not inflate the repair price. The diagnostic and repair cost stays the same as a weekday call.
Heat Exchanger Condition
If we find a cracked heat exchanger, the repair cost jumps significantly. In some cases, replacement is the safer option, and we explain both paths clearly.
Airflow and Duct Issues
If a clogged filter, dirty blower, or restricted duct caused the failure, we address it as part of the repair. Duct repairs are quoted separately if needed.
