Here is a quick look at the typical furnace repair costs:
- Lowest Cost: $132.
- Average Cost: $317.
- Highest Cost: $501.
Furnace Repair Costs By Part
One of the biggest factors in determining the total cost will be the specific part that needs to be replaced. Regardless of whether the furnace is gas or electric, these machines are complex with a lot of working parts.
Let’s take a look at the parts of a furnace and how much it will cost for repairs below.
Thermostat
The thermostat should be the first thing you check if you are experiencing any furnace issues. Thermostats can fail due to a blown fuse, faulty wiring, or simply old age.
Thermostat repairs usually cost between $100-$300, with full replacements costing upward of $600.
Blower Motor
The blower motor is in place to push air through the ducts, which is an essential function of any furnace. Blower motor repairs can really vary from $150-$2,000.
Gas Valve
Every gas furnace requires gas or propane to work properly. Gas valves allow those substances to flow safely into your unit. The majority of gas valves will cost anywhere from $200-$600 to replace.
Flame Sensor
Thermocouples are furnace sensors that detect whether or not the pilot light is on. These gadgets are typically featured in all types of gas furnaces, costing between $150-$250 to replace. In most cases, these parts will fail due to poor maintenance.
Ignitor
The ignitor fails more than any other part of a furnace. Ignitors usually cost $150-$250 to replace. It will cost more to replace in an emergency i.e. during late night hours. In this case, homeowners may pay upward of $500.
Draft Inducer Motor
The function of a draft inducer motor is quite complex when compared to most other parts. It pulls gases through the heat exchanger and out of the flue in an effort to prevent the buildup of carbon monoxide.
Carbon monoxide buildup can be a serious safety issue, making repairs an immediate need. Repairs and replacements of this component range from $200-$1,500.
Transformer
Transformers convert electrical power that flows into your home into a lower voltage that’s used in the furnace. The part combined with labor will likely cost between $100-$175.
Flue Pipe
The flue is a crucial safety feature of the furnace, responsible for carrying carbon monoxide and any leftover combustion gasses out of the home. Replacements can cost anywhere from $400-$800.
Oil Combustion Chambers
Oil combustion chambers are constructed of two components: the molded ceramic fiber oil combustion chamber as well as the actual oil chamber. Oil will sit in the oil chamber prior to being transferred to heat in the combustion chamber.
This process helps to heat your home efficiently. Combustion chambers cost $200-$600 and oil chambers cost $100-$200 to replace.
Control Or Circuit Board
Replacing a control board will cost between $200-$600. How much you’ll pay depends on the brand and age of your furnace. High-efficiency models are typically more expensive to replace.
Relay Or High Limit Switches
This piece allows electricity to reach inside the furnace’s electrical components. The part alone will cost from $5-$20, but labor and diagnostics will run between $150-$300.
Furnace Filter
New furnace filters cost $1-$35 and can be replaced as a simple DIY task. These filters should be replaced about every 90 days.
Heat Exchanger
The heat exchanger is responsible for heating up the air that’s ultimately pushed through the house. As the part ages, it can develop cracks which can allow carbon monoxide to leak into the home.
Heat exchanger repairs can cost between $100-$200, with full replacements potentially costing up to $1,500.
Coils
The evaporator coil or furnace condenser is part of the AC system, even though it lives inside the main furnace duct. It also uses the blower and ductwork. The coils will cost $600-$2,000 for replacements.
Burners
To repair the burners, homeowners can expect to pay between $150-$450. The burners will combine air with the furnace’s fuel source, resulting in heat production. The good news is most burners will last the lifespan of the furnace.
Here is a quick breakdown of furnace repairs by part:
| Furnace Part | Average Cost |
| Thermostat | $100-$600 |
| Blower Motor | $150-$2,000 |
| Gas Valve | $200-$600 |
| Flame Sensor | $150-$250 |
| Ignitor | $150-$500 |
| Draft Inducer Motor | $200-$1,500 |
| Transformer | $100-$175 |
| Flue Pipe | $400-$800 |
| Oil Combustion Chambers | $100-$600 |
| Control Or Circuit Board | $200-$600 |
| Relay Or High Limit Switches | $150-$300 |
| Furnace Filter | $1-$35 |
| Heat Exchanger | $100-$1,500 |
| Coils | $600-$2,000 |
| Burners | $150-$450 |
How Much Does Furnace Repair Labor Cost?
The majority of furnace repairs will cost between $50-$150 per hour for labor. Of course, it’s always wise to budget for the cost of parts and labor ahead of time.
A dirty filter is undoubtedly the quickest fix associated with a furnace. The more complex the repair or replacement, the higher the labor costs will go.
DIY Vs Professional Furnace Repair
It’s always best to hire a professional team for furnace repairs and replacements. Attempting furnace repairs yourself can be quite dangerous, especially if doing so with a gas furnace.
DIY-ing electric furnace repairs can be dangerous, as well. You could end up with a high-voltage shock and potentially create a fire hazard.
