- Gas Furnaces: These repairs can range from $300 to $1,200, particularly for issues with heat exchangers or gas valves.
- Oil Furnaces: Repairing an oil furnace can cost $300 -$900, with higher costs for fuel delivery system problems.
Common Furnace Repairs and Their Costs
Here’s a breakdown of the most common furnace repairs and their typical price ranges:
Thermostat Replacement or Repair
- Cost Range: $100–$600
- A faulty thermostat can cause inconsistent temperatures or prevent the furnace from running. Repairs are typically affordable unless a full replacement is required.
Blower Motor
- Cost Range: $150–$2,000
- The blower motor is responsible for circulating warm air throughout your home. Repairs for minor issues, such as lubricating components, are on the lower end, while replacing the entire motor can cost much more, especially for variable-speed models.
Draft Inducer Motor
- Cost Range: $200–$1,500
- The draft inducer motor helps expel exhaust gases from your furnace. Repairs or replacements can be costly, depending on the motor’s complexity and brand.
Ignitor
- Cost Range: $150–$500
- If your furnace fails to ignite, the ignitor may need repair or replacement. This is a common and relatively affordable repair.
Flame Sensor
- Cost Range: $150–$250
- The flame sensor ensures safe operation by detecting whether the furnace burner is lit. Dirty or damaged sensors can often be repaired, but replacements are straightforward and affordable.
Gas Valve
- Cost Range: $200–$600
- The gas valve controls the flow of gas into the furnace. Repairs are necessary when the valve malfunctions, leading to inefficient heating or no heat at all.
Circuit Board
Cost Range: $200–$600
The circuit board manages the furnace’s electrical functions. A damaged or failing board may need repair or full replacement, which can be moderately expensive.
Flue Pipe
- Cost Range: $400–$800
- The flue pipe safely removes exhaust gases from your furnace. Corrosion or damage may require a full pipe replacement, which can be costly but essential for safety.
Relay Switch
- Cost Range: $150–$300
- The relay switch controls the furnace’s electrical functions. Repairs are typically affordable but crucial to restore proper operation.
Transformer
- Cost Range: $100–$175
- The transformer converts power to a voltage the furnace can use. Replacements are quick and relatively inexpensive.
Combustion Chambers
- Cost Range: $100–$600
- The combustion chamber houses the burning fuel that generates heat. Repairs are often necessary for cracked or damaged chambers to prevent safety risks.
Heat Exchanger
- Cost Range: $100–$1,500
- The heat exchanger transfers heat from the combustion process to the air circulating in your home. Cracks or damage often lead to expensive repairs due to safety concerns.
Coils
- Cost Range: $600–$2,000
- The furnace’s coils play a key role in heating and airflow. Repairs or replacements for damaged coils can be one of the most expensive furnace fixes.
Burners
- Cost Range: $150–$450
- Burners are responsible for igniting and maintaining the flame in gas furnaces. Cleaning or replacing burners is a common repair.
Furnace Filter
- Cost Range: $1–$35
- While not a major repair, replacing your furnace filter is an inexpensive and essential maintenance task that can prevent more costly issues.
Factors That Affect Furnace Repair Costs
Several factors influence how much you’ll pay for furnace repairs, including:

Type of Furnace
Your home’s furnace type plays a significant role in repair costs. Electric furnaces are often the most affordable to repair, while gas and oil furnaces typically cost more due to their complex components and specialized repair needs.
Age of the Furnace
Older furnaces require more frequent repairs, and replacement parts may be harder to find, increasing the cost. In some cases, it may be more cost-effective to replace an older unit rather than continually repair it.
Nature of the Issue
The severity and complexity of the problem directly impact costs. Simple fixes like replacing a thermostat or cleaning a filter are inexpensive, but major repairs, such as replacing a blower motor or heat exchanger, can be significantly more expensive.
Labor Costs and Location
Repair costs vary depending on where you live. Urban areas often have higher labor rates than rural areas. Additionally, emergency or after-hours repairs typically incur higher fees.
Maintenance History
Furnaces that are regularly maintained are less likely to require costly repairs. Skipping maintenance can lead to neglected issues that worsen over time, resulting in higher repair expenses.
Warranty Coverage
Certain parts or labor costs may be covered if your furnace is still under warranty, significantly reducing your out-of-pocket expenses. Be sure to check your warranty terms before scheduling repairs.
