Picture a cold snap after an ice storm. You turn the thermostat up before bed, hear the furnace try to start, and then the house goes quiet. Most furnace breakdowns come from a short list of parts: igniters, flame sensors, pressure switches, blower motors and control boards. A trained provider can usually find which one failed with a careful set of tests.
Blogmember Heating & Air connects homeowners in the Nashville area with independent providers who repair gas and electric furnaces. We do not do the repair ourselves. We send your request to a provider near you and share the questions that help you judge a diagnosis. The provider inspects the furnace, explains the problem, writes up a price and handles the repair if you approve it.
A rotten egg smell near the furnace or a carbon monoxide alarm is an emergency. Do not flip switches, light anything or try to find the leak yourself. Get everyone out of the house and contact your gas utility's emergency line from outside. Stay out until the utility says it is safe. Repairs come after that.
If you have no CO detector, ask the provider about adding one near the bedrooms and on each floor.
Say the furnace stopped on a weeknight. A few quick checks can sometimes bring the heat back, or at least tell the provider where to look.
Set it to heat and raise it a few degrees above the room. Replace the batteries if the screen is dim or blank.
Most furnaces have a switch that looks like a light switch on or near the unit. Make sure it is on. Check the breaker panel and reset a tripped furnace breaker once.
A badly clogged filter can make the furnace overheat and shut itself off. Replace it if it is gray and packed with dust.
Furniture or rugs over return grilles starve the system of air. Clear them and open the supply vents in each room.
The provider asks what you noticed and when. Then they open the cabinet and read any blinking error code on the control board. Many furnaces store a code that points toward the problem.
Expect checks on the igniter, flame sensor, pressure switch, inducer motor, gas pressure and venting. A careful provider also looks at the heat exchanger for cracks and checks for carbon monoxide.
You should get a price on paper before the repair starts. Ask the provider to explain which finding caused the breakdown.
A coated sensor cannot confirm the flame, so the furnace shuts off. Cleaning or replacing it is a quick job.
Hot surface igniters crack with age. A new one is a common winter repair.
These parts make sure exhaust gases vent safely. When one fails, the furnace will not light.
If the burners light but no air moves, the blower motor or its capacitor may be the cause.
Power surges and age can damage the board. It is one of the more expensive repairs.
Say your furnace is over 15 years old, needs a costly part and has already had several repairs. Replacement may make more sense than another fix. A cracked heat exchanger often means replacement too, since the part can let combustion gases into the air. Ask the provider for written prices on both choices so you can compare.
A careful provider answers these without hesitation. If the answers feel rushed or unclear, pause and get a second opinion. Request a callback to check provider availability, or send a request.
Checks for gas leaks, carbon monoxide, venting problems and heat exchanger cracks during the visit.
The provider reads the control board code to narrow down the failed part.
Igniter and flame sensor are tested and cleaned or replaced.
You get a price on paper with parts and labor listed before any repair begins.
These typical U.S. ranges vary with the furnace brand, the part, access and local labor rates. Ask the provider for a written quote that lists parts and labor before work starts.
| Repair | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $75 to $200 | Ask if it applies to the repair |
| Flame sensor clean or replace | $100 to $300 | Common cause of short cycling |
| Hot surface igniter | $150 to $400 | Wears out with age |
| Pressure switch | $150 to $450 | Safety part for venting |
| Blower motor | $400 to $1,200 | Depends on motor type |
| Control board | $300 to $900 | Check for surge damage |

No obligationShort cycling often comes from a dirty flame sensor, a clogged filter, an overheating heat exchanger or a thermostat problem. Replace the filter first. If it continues, a provider can test the sensor and safety switches.
The burners may not be lighting because of a failed igniter, flame sensor or pressure switch. The thermostat fan may also be set to on. A provider can find the cause.
You can change filters, check breakers and replace thermostat batteries. Gas valves, burners, igniters and venting should be left to a trained provider for safety.
