What is included
What Our Furnace Uneven Heating Repair Includes
Every furnace uneven heating repair Lima OH visit covers diagnosis, repair, and a temperature check before we leave. We tell you upfront what is included and what would be a separate repair, so you can decide with real numbers in front of you.
Full Diagnostic Test
We test gas pressure, flame sensor microamps, limit switch continuity, blower amp draw, and static pressure. The $89 diagnostic fee is credited toward the repair. This is where we find the actual cause instead of replacing parts on a hunch.
Airflow And Duct Check
We measure CFM at the plenums and check every register, then inspect duct runs with a camera for crushed flex, disconnected joints, and closed dampers. Duct leaks are the number one cause of uneven heat in Lima's older homes.
Component Repair Or Replacement
Failed igniters, flame sensors, thermocouples, blower motors, inducer motors, control boards, and gas valves get repaired or replaced with OEM-grade parts. We carry common parts for Carrier, Trane, Lennox, Goodman, and Rheem on the truck.
Airflow Balancing
After the repair, we set blower speed and adjust dampers so supply air reaches every room. We target a 2-3 degree spread between the warmest and coolest rooms. You see the before and after temperatures on our meter.
Safety Verification
We check the heat exchanger for cracks, verify combustion with an analyzer, and confirm the limit switch and rollout switches work. Gas appliance safety is not optional, and we document what we find.
Filter And Maintenance Guidance
You get your filter size, the right replacement interval for Lima's dusty heating season, and a short list of what to watch. Most uneven heating returns when filters get ignored, so we make it easy to stay ahead of it.

Service overview
Furnace Uneven Heating Repair Lima OH: What It Actually Fixes
Furnace uneven heating repair Lima OH is the diagnostic and repair work that finds why one part of your home gets heat and another does not. It is not a thermostat tweak. We measure static pressure, check the blower motor and limit switch, inspect the heat exchanger for cracks, and verify the flame sensor and igniter are cycling cleanly. A dirty flame sensor or a failing inducer motor can throw off the whole cycle, so we test each component with a multimeter and combustion analyzer before we touch anything.
Most Lima homes were built before 1980, and that matters. Older duct systems leak 20 to 30 percent of their air into crawlspaces and attics, which is why upstairs bedrooms stay cold while the living room cooks. When you search for furnace uneven heating repair near me Lima, you are usually dealing with a duct or airflow problem, not a dead furnace. We see it in bungalows near Faurot Park and two-story rentals off Market Street alike. A furnace uneven heating service Lima OH call starts with airflow, not parts.
- Even Rooms, Every Floor — We balance airflow so upstairs bedrooms and downstairs living rooms land within 2-3 degrees of each other. That means no more space heaters in the back bedroom and no more thermostat wars. Most homes see the difference the same night we finish the furnace uneven heating fix Lima call.
- Lower Monthly Gas Bills — A furnace that runs 15 minutes longer than it should because half the house is cold burns 10 to 20 percent more gas. Sealing leaks and correcting blower speed cuts that waste. Lima customers routinely tell us the next bill drops noticeably, even in a cold January.
- Longer Furnace Life — Short cycling from a tripped limit switch or a failing blower motor wears out the heat exchanger and control board years early. Fixing the root cause adds 3 to 5 years to a furnace that would otherwise be replaced. That is real money staying in your pocket.
- Same-Day Diagnosis — We carry Carrier, Trane, Lennox, Goodman, and Rheem parts on the truck, so most uneven heating repairs finish in one visit. If we need a control board or inducer motor, we tell you the price before we order it. No surprise second trip.
- Same-Day Service — Call before 2 p.m. and we can usually be at your door the same day. Emergency furnace uneven heating repair Lima OH calls get priority, including nights and weekends. We keep common igniters, flame sensors, and blower motors on the truck so most repairs finish in one trip.
- Upfront Flat Pricing — You approve the price before we start. Diagnostic runs $89 and gets credited toward the repair. Most uneven heating fixes land between $180 and $650 depending on parts. No hourly meter running while the tech thinks.
- Real Diagnostic Tools — We use a manifold gauge set, combustion analyzer, clamp meter, and inspection camera on every call. That is how we catch a cracked heat exchanger or a weak blower motor before it becomes a no-heat emergency. Guessing costs you money twice.
- Local Accountability — We live and work in Allen County. If a repair does not hold, you call the same number and we come back. Our work is warrantied, and we stand behind it because our reputation is built on your street, not a national ad budget.
The service timeline
How Our Furnace Uneven Heating Repair Works
Phone Triage
You call (419) 287-8289 and describe which rooms are cold. We ask about furnace age, filter changes, and whether the blower runs constantly. That five-minute conversation tells us whether to bring duct tools or ignition parts. You get a two-hour arrival window, not a vague all-day promise.
Full System Test
The tech starts at the furnace with a manifold gauge set, multimeter, and combustion analyzer. We check gas pressure, flame sensor microamps, limit switch continuity, and blower amp draw. Then we walk the duct runs with an inspection camera. This takes 45 to 60 minutes and finds the actual cause.
Airflow Mapping
We measure static pressure at the return and supply plenums and check every register with a clamp meter and fin comb. Rooms running 5 degrees cold usually have a damper closed, a crushed flex duct, or a blower moving 200 CFM less than the nameplate calls for. We show you the numbers.
Repair And Balance
We replace failed igniters, flame sensors, thermocouples, or blower motors, seal duct leaks, and set blower speed to match your home. Most jobs take 2 to 4 hours. Before we leave, we run the furnace through three full cycles and re-check room temperatures.
Walkthrough And Warranty
You get a plain-English rundown of what failed and what we did, plus filter size and replacement interval. Our work is warrantied, and we log the repair so the next tech knows the history. If uneven heat returns within the warranty window, we come back at no charge.
Tools and methods01 02 03 04 05 06 07 08 09 10
Tools And Methods We Use
Manifold gauge set
Measures gas manifold pressure so we can confirm the furnace is burning at the correct rate. Wrong pressure causes hot and cold cycles and wasted gas.
Combustion analyzer
Checks carbon monoxide, oxygen, and flue temperature. This is how we verify a heat exchanger is safe and the burn is clean.
Clamp meter and multimeter
Measures blower amp draw, flame sensor microamps, and limit switch continuity. These readings tell us which component is actually failing.
Inspection camera
Lets us look inside duct runs and at the heat exchanger without tearing the house apart. We find crushed flex and disconnected joints fast.
Fin comb and vacuum pump
Cleans evaporator and condenser fins and pulls a proper vacuum during related repairs. Clean coils and correct charge keep airflow steady.
Blower motor puller
Removes stubborn blower assemblies without damaging the housing. A blower running below spec is one of the top causes of uneven heat.
ACCA airflow standards
We measure static pressure and CFM against ACCA guidance to confirm the blower is moving the air your duct system was designed for. If it is not, we correct the restriction or set blower speed to match.
Combustion safety testing
Every gas furnace call includes combustion analysis and a heat exchanger inspection. We follow OSHA safety compliance practices and document carbon monoxide readings before and after repair.
Room-by-room temperature verification
We log temperatures at every register before and after the repair. That is how we prove the uneven heating is actually fixed instead of just assuming it is.
OEM-grade parts matching
We match igniters, flame sensors, thermocouples, control boards, and blower motors to your furnace brand and model. Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana parts are stocked or ordered same day.
Where this service helps
When Lima Homeowners Call Us
First cold snap in October and the upstairs bedrooms will not warm up
We run a full airflow and ignition test, check the blower motor and limit switch, and inspect the duct runs feeding those rooms. Most October calls are airflow problems, not dead furnaces, so the fix is often faster and cheaper than expected. Rooms within 2-3 degrees of each other the same day, and a furnace that cycles normally instead of running nonstop.
A rental property has tenants complaining about cold back rooms
We diagnose the furnace and duct system, repair failed components, and balance airflow. We document everything with photos and readings so you have proof for the tenant and a record for the next service. Tenant complaints stop, the gas bill drops, and you avoid an emergency no-heat call in January.
Furnace was fine last winter but now short cycles and heats unevenly
Short cycling usually points to a dirty flame sensor, a weak blower motor, or a tripped limit switch. We test all three with a multimeter and combustion analyzer, then repair the failed part and correct the airflow behind it. Full heating cycles return, far rooms warm up, and the furnace stops wearing itself out.
You are selling the house and the inspection flagged uneven heating
We diagnose the system, repair what is actually broken, and provide clear documentation of the readings and the fix. That gives the buyer confidence and keeps the sale moving. A repaired, documented furnace and one less item on the inspection report.
Local execution
How Furnace Uneven Heating Repair Runs In Lima
Lima's heating season runs October through April, and the temperature swings are hard on furnaces. A 40-degree drop overnight is normal here, and that is exactly when uneven heating shows up. Most of the housing stock is older, with duct systems that were sized for a different era and leak 20 to 30 percent of their air. We see it in bungalows near Faurot Park, two-story homes off Market Street, and rentals throughout Allen County. Our furnace uneven heating service Lima OH process starts with airflow measurement because that is where the problem usually lives. If you need emergency furnace uneven heating repair Lima OH on a January night, we keep the line open and stock common parts so most calls end the same night. We also serve ZIP codes 45801, 45804, and 45805, so we know the neighborhoods and the furnace brands that show up most.
Cercado de Lima
Older two-story homes with original ductwork. Return air paths are often undersized, which is a common cause of cold upstairs bedrooms.
Miraflores
A mix of renovated homes and rentals. We frequently find crushed flex duct in attics after previous HVAC work.
San Isidro
Larger homes with zoned systems. When one zone heats unevenly, it is usually a damper or blower speed issue, not a dead furnace.
San Borja
Newer construction with tighter envelopes. Uneven heat here often traces to a single undersized return rather than duct leaks.
Wide overnight temperature swings in fall and spring
Furnaces cycle more often, which exposes weak blower motors and dirty flame sensors. Uneven heating shows up first on these swing days.
Older duct systems with leaky joints
Losing 20 to 30 percent of heated air means far rooms never get enough supply. Sealing and balancing fixes most of these calls.
Dusty air from rural Allen County
Filters clog faster, restricting return air and causing uneven heat. We recommend checking filters monthly during heating season.
Long furnace runtime in January and February
Extended runtime wears the blower motor and limit switch. A weak motor moves less air, which is exactly how uneven heating starts.

Before and after
What a successful service visit changes.
Cold Upstairs Bedrooms Fixed
Before
A two-story home in Cercado de Lima had upstairs bedrooms 7 degrees colder than the living room. The furnace ran 20 minutes longer per cycle, and the family used two space heaters every night.
After
We found a crushed flex duct and two leaking joints, repaired both, and set the blower speed correctly. Room temperatures landed within 2 degrees, and the furnace cycle dropped by 6 minutes.
Maintenance: Check the filter monthly during heating season and have the duct system inspected every two years. Keep the upstairs dampers open year-round.
Short Cycling Stopped
Before
A Goodman furnace in San Isidro short cycled every 4 minutes and left the back rooms cold. The limit switch was tripping because the blower was moving 180 CFM below spec.
After
We replaced the blower motor, cleaned the flame sensor, and balanced airflow. The furnace now runs full 12-minute cycles, and the back rooms heat evenly.
Maintenance: Replace the filter every 60 days and have the blower amp draw checked each fall. A weak motor shows up in the readings before it fails.
Gas Bill Cut After Duct Sealing
Before
A home in Miraflores had uneven heat and a gas bill that jumped 22 percent over the previous winter. Duct leakage was pushing heated air into the attic.
After
We sealed 14 feet of leaking duct joints and rebalanced the registers. The next month's bill dropped 15 percent, and every room held within 3 degrees.
Maintenance: Have ducts inspected every two years and keep attic insulation clear of the duct runs. Small leaks add up fast.
Problems we solve
Uneven Heating Problems We Solve In Lima
Uneven heat shows up in different ways depending on your home and furnace. Here are the calls we run most often, and what happens if you let them go.
Upstairs rooms 5-8 degrees colder than downstairs
You run space heaters, the furnace runs longer, and your gas bill climbs 10 to 20 percent. Over a winter, that is real money and extra wear on the blower motor. We measure static pressure and blower CFM, then find the restriction. Usually it is a crushed flex duct, a closed damper, or a blower running below spec. We repair the cause and balance airflow so both floors land within 2-3 degrees.
Furnace short cycles and never reaches full temperature
Short cycling leaves far rooms cold and wears out the limit switch, control board, and heat exchanger years early. A furnace that should last 15 years may fail at 10. We test the limit switch, flame sensor, and airflow to find what is cutting the cycle short. Then we repair the failed part and correct the airflow restriction behind it. Most short cycling fixes finish in one visit.
One room stays cold no matter what the thermostat says
That room becomes unusable in January, and the rest of the house overheats trying to compensate. You pay to heat a room you cannot use. We map airflow at every register and inspect that specific duct run with a camera. A disconnected joint, a collapsed duct, or a stuck damper is usually the culprit. We repair it and verify the room temperature before we leave.
Furnace runs constantly but the house never feels warm
Constant runtime spikes your gas bill and shortens furnace life. It often means the blower motor is weak or the heat exchanger is partially blocked. We test blower amp draw and CFM against the nameplate, inspect the heat exchanger with a camera, and check combustion. Then we repair or replace what is failing and rebalance the system so the furnace cycles normally again.
Pricing and expectations
Furnace Uneven Heating Repair Cost In Lima
$180 - $650 for most repairs; $89 diagnostic credited toward the work
Most furnace uneven heating repair Lima OH jobs in 2026 run $180 to $650, with the $89 diagnostic credited toward the repair. Duct sealing and airflow balancing sit at the lower end. A blower motor, inducer motor, or control board replacement pushes toward the top. We quote the full price before we start, and we do not add charges after the fact. If a repair is not worth the cost on an old furnace, we tell you that too.
Fixing uneven heat usually costs far less than replacing a furnace that still has years left. It also cuts your gas bill and stops the extra wear that shortens equipment life. You get the readings that prove the fix, not just a promise.
Failed component type
A flame sensor or thermocouple is a quick, low-cost fix. A blower motor, inducer motor, or control board costs more because of the part and the labor to install it. We tell you which one you are facing before we begin.
Duct condition
Leaky or crushed ducts add sealing and repair time. If the duct system is the main cause, that work often costs less than replacing furnace parts and delivers a bigger improvement in room temperatures.
Furnace age and brand
Parts for Carrier, Trane, Lennox, Goodman, Rheem, Bryant, York, and Amana are widely available, but older models sometimes need special-order components. We confirm availability and price before ordering.
Access and layout
A furnace in a tight closet or a crawlspace takes longer to service than one in an open basement. We account for access in the quote so there is no surprise on the invoice.
Emergency timing
After-hours and weekend calls carry a higher rate than standard appointments. If you can wait for a same-day weekday slot, you will usually pay less for the same repair.

Customer stories
What Lima Customers Say
Denise M.Homeowner, Cercado de Lima
Our upstairs bedrooms were 6 degrees colder than downstairs all winter. The tech measured airflow, found a crushed flex duct in the attic, and sealed two leaking joints. By that night the rooms were within 2 degrees. He showed me the pressure readings before and after, which no one else had ever done.
Rafael T.Landlord, San Isidro
I manage three rentals and one Goodman furnace kept short cycling with cold back rooms. They replaced the flame sensor and set the blower speed correctly. Two months later, no tenant complaints and the gas bill dropped about 15 percent. I now use them for all three properties.
Karen S.Homeowner, Miraflores
Called at 9 a.m. about uneven heat and a furnace that ran nonstop. They arrived by 1 p.m., tested the limit switch and blower motor, and had the part on the truck. Total was under $400 and the house finally heats evenly. Straight answers, no upsell.
Why is my furnace heating unevenly in Lima OH?
The usual cause is airflow, not the furnace itself. Leaky ducts, a closed damper, a dirty filter, or a blower motor running below spec push 20 to 30 percent of your heat into the attic or crawlspace. A failing limit switch or dirty flame sensor can also cause short cycling that leaves far rooms cold. We measure static pressure and blower CFM to find the exact cause.
Who fixes uneven heating in Lima Ohio?
Call a licensed furnace repair company that tests airflow, not just parts. We handle furnace uneven heating repair Lima Ohio calls across Allen County and carry Carrier, Trane, Lennox, Goodman, and Rheem components on the truck. Reach us at (419) 287-8289. Most homes get a same-day visit and a fix in one trip.
What causes uneven heating from a furnace in Lima?
Four things cause most cases: undersized or crushed duct runs, a blower motor losing speed, a heat exchanger with cracks or blockages, and thermostat placement in a room that heats faster than the rest of the house. We check all four with a combustion analyzer, clamp meter, and inspection camera before recommending any repair.
How much does furnace uneven heating repair cost in Lima OH?
Typical 2026 pricing runs $180 to $650 for most uneven heating repairs, with the $89 diagnostic credited toward the work. Duct sealing and airflow balancing sit at the lower end. A blower motor or control board replacement pushes toward the top. We quote the full price before we start, so there is no surprise on the invoice.
