Most furnace repairs we run in the Greenville area land between $200 and $1,100. The tech finds the cause first, and you get a flat-rate price before we touch anything. The expensive ones, a blower motor or a heat exchanger, are less common, and we explain below when they are worth fixing.
About two out of three homes in the city of Greenville heat with electricity, not gas. In Greer it is closer to half and half (U.S. Census Bureau, American Community Survey 2018 to 2022). We repair both: gas furnaces, electric furnaces, and the electric heat strips inside air handlers. If you have a heat pump, see our heat pump page for that system.
On every gas furnace call, the tech takes a carbon monoxide reading and looks at the heat exchanger, even when the call is for something else. A furnace that lights is not the same as a furnace that is safe to run.
What furnace repair costs in Greenville
These are our prices, from our own price book, not a national average.
Igniter: $150 to $350
The hot surface igniter glows to light the gas, and it cracks with age. It is a common reason a gas furnace runs its fan and never lights.
Flame sensor: about $95 to clean, $200 to $400 to replace
If your furnace lights, runs a few seconds, then shuts off and tries again, a dirty flame sensor is the usual cause. Cleaning fixes most of them.
Pressure, limit and rollout switches: about $210 to $255
These are safety switches. When one fails, the furnace locks itself out. When one trips, we find out why before replacing anything, because a tripped switch is usually a symptom of something else: a clogged filter, a blocked vent, or a plugged condensate drain on a high-efficiency furnace.
Control board: $420 to $925
The low end is a universal board that fits. The high end is a furnace that needs the factory part.
Blower motor: $600 to $1,500
A standard motor sits at the low end. A variable-speed (ECM) motor runs higher.
Inducer motor: $890 to $1,080
The small fan that clears exhaust out of the furnace before the burners light. A loud whine or rattle at startup is the warning sign.
Gas valve: $400 to $800
A safety part that controls the gas going to the burners.
Heat exchanger: $2,000 to $4,000
The part is often covered under the manufacturer warranty when the furnace was registered, which brings the cost down a lot. On an older furnace, this is usually the repair where replacement wins.

The safety check on every gas furnace call
Gas furnaces make carbon monoxide every time they run. The heat exchanger is the metal wall that keeps it in the flue and out of your air. When it cracks, that wall leaks.
So on every gas furnace call, the tech takes a CO reading and inspects the heat exchanger, not just the part you called about. If we find a crack, we shut the gas off at the furnace, show you the photos, and give you the price to repair it and the price to replace the furnace. You decide with the evidence in front of you.
If your carbon monoxide alarm goes off, get everyone out of the house and call 911 from outside. Then call us.
Repair or replace?
Multiply the furnace's age by the repair cost. If the answer is over $5,000, replacement usually makes more sense. A $300 igniter on a 15-year-old furnace comes to $4,500, so fix it. A $3,000 heat exchanger on an 18-year-old furnace comes to $54,000, so replace it.
You get the numbers for both paths and you make the call. When the repair is the better deal, we will tell you, even though it costs us a sale. Replacement estimates are free, and our furnace replacement page lists what a new one costs.
Flat-rate pricing, no overtime
You approve the price before we start, and it is the price for the repair. It does not go up if the job takes longer than planned, and there are no overtime charges.

"I called First Class Heating & Air for a second opinion after another company could not find the part they said my unit needed. After finding that my system did Not need the part, First Class fixed the leak and replaced the refrigerant at less than half the cost of the other company's estimate. I appreciate companies being honest and upfront with customers."
"Talk about honest because we know nothing when it comes to AC. The technician did not find any issues when he could’ve told us there were many and we would’ve never known. That goes to show this company’s technicians have integrity and knowledge. He even took pictures of everything to show us."
