HVAC Circuit Board Repair Cost

The price to repair an HVAC circuit board is $100 to $600. This job often includes replacing it.

HVAC circuit boards usually need repair or replacement due to other electrical problems in the system, such as:

  • Dirty or incorrect fuses.

  • Bad switches.

  • Worn capacitors.

Since these parts are usually pretty inexpensive, about $50 to $200, it’s tempting to do it yourself. Keep in mind that faulty part replacement is one of the most common causes of circuit board failure.

HVAC Fan Motor Replacement Cost

Replacing your HVAC fan motor ranges from $200 to $700. A condenser fan motor costs $200 to $500, and it’s found in your exterior AC unit. A blower fan motor runs $400 to $700 and goes inside your furnace or air handler.

These motors operate fans that help your condenser circulate conditioned air through your ductwork. If they’re making screeching or banging noises or simply aren’t turning on, they may need repair.

AC or Furnace Replacement Cost

Installing central air costs $3,800 to $7,500. The price to replace a furnace ranges from $2,600 to $6,200.

Most units last 10 to 20 years with yearly upkeep. You’ll want to consider a full replacement if repairs cost 50 percent of a new one or it’s near the end of the lifespan.

HVAC Duct Replacement Cost

The cost to replace ductwork ranges from $500 to $2,000. You’ll probably need to do this once the existing equipment is 20 to 30 years old.

Compressor Replacement Cost HVAC

Compressor replacement costs $750 to $2,000. It is one of the largest single components of your HVAC system. If it breaks down, you may want to consider getting a new AC unit.

The compressor can wear out over time, especially if it gets dirty. When it fails, you’ll notice a lack of cool air coming through the vents.

HVAC Coil Replacement Cost

The cost to replace HVAC coils ranges from $400 to $1,500. The evaporator coil runs $400 to $1,000, while condenser coil prices are $500 to $1,500.

For most systems, the evaporator coil sits inside near the air handler. It cycles refrigerant to absorb heat and humidity. When it gets dirty, it can freeze or break.

The condenser coil wraps around other components in the outside unit. It releases the heat and humidity outside. Given its location, it’s also likely to fail due to dirt accumulation and lawn debris.

HVAC TXV Replacement Cost

Replacing an HVAC thermostatic expansion valve costs $100 to $500. It’s also called a thermal expansion valve. Manufacturers may list it as TXV or TEV.

The TXV controls the pressure of the refrigerant as it goes to the evaporator coil. If it gets clogged with oil or moisture, it may stop working.

HVAC Freon Leak Repair Cost

The price to recharge AC ranges from $100 to $350. You may pay up to $1,500 to repair refrigerant leaks.

Although you can find refrigerant at most home improvement stores, this isn’t a job for someone without training. It’s toxic and can seriously injure you or your family. You must know:

  • Which refrigerant works with your system.

  • The location of all leaks.

  • How to seal the leaks.

Keep in mind that the old Freon, also known as R-22, is no longer available. If your air conditioner is more than 15 years old, you should consider replacing it.

Repair Costs for Other Heater Types

If you have another heater, like a boiler or heat pump, you’ll pay $150 to $600 for repairs.

HVAC SystemTypical Cost
Heat Pump$175-$600

While most HVAC technicians can service heat pumps, you’ll need to ask if they have experience working with a boiler or baseboard heater.

Boiler Repair Costs

The cost to service a boiler ranges from $200 to $600. Common problems include:

  • Mineral buildup.

  • Faulty fuel connections.

  • Clogged or broken radiator valves.

Boilers heat water and send it through pipes to radiators in various rooms. They can handle a larger capacity, which makes them popular in multifamily housing. If you’re comparing boiler vs. furnace, keep in mind that they’re completely different systems.

Heat Pump

Heat pump repair costs $175 to $600. Since this system runs like an air conditioner, you’ll have similar issues, like dirty coils or a broken fan motor.

Heat pumps work by moving heat from the home to the outdoors, or vice versa. Air-source models are popular alternatives to furnaces in regions with mild winters. Ground-source systems are more expensive but can work in almost any climate. If you’re thinking about replacement instead of repair, you can expect to pay:

Electric Wall & Baseboard Heating System Repair Costs

The cost to repair a baseboard heater runs $150 to $400. They most commonly need fixing because of a faulty heating element, dirty parts or bad wiring.

Installing a baseboard heater costs $450 to $1,200 for the average home. This system uses convection to warm air and circulate it through a room. If you keep them clean and allow plenty of airflow, they may last 20 to 30 years.
