Thermocouple Replacement A thermocouple costs about $150 to $250 to replace. This is an important part of a gas furnace since it opens the gas line when the pilot light is lit and will close the gas line when it’s not.
Furnace heat exchanger repair estimate
A heat exchanger replacement costs $1,000 to $3,000, depending on the furnace size, age, and brand. Most HVAC technicians replace heat exchangers instead of repairing them due to possible carbon monoxide leaks.
Furnace short-cycling repair cost
Furnace short-cycling repair costs $100 to $400. Short-cycling happens when the furnace shuts off too quickly before reaching its thermostat setting. Common fixes include replacing the flame sensor, circuit board, or thermostat.
Other causes include:
- Clogged air filters
- Blocked heat grates, exhaust fan, or vent
- Damaged fan-limit switch
- Ignitor or flame-sensor failure
- Dirty or faulty blower-motor wheel
- Oversized furnace
