Heat pumps are a popular method for heating and cooling homes. They are much more energy-efficient than other HVAC systems because they only use electricity to move heat, not to generate it. Heat pumps develop a few problems over their lifetimes, which may need repair to keep the system completely operational. The type of heat pump you have and the type of repair necessary vary from system to system, which accounts for a wide range of costs.

The average range is $250 to $1,000, with most homeowners paying around $650 for a heat pump blower motor replacement.

Heat Pump Repair Costs per Hour

While some of the repair cost is for the part(s) needed, the labor and how long it takes the technician to make the repair make up a large part of the price. Most technicians have a standard diagnostic fee of around $80 - $90, which includes travel time and identifying the problem. You pay this fee even if they arrive and discover that it was user error, and nothing is wrong with the system. In some cases, they waive this fee if you agree to have the work done. Most technicians charge between $85 and $95 an hour for labor, although some charge a flat fee for small jobs of up to $285 in labor.

Heat Pump Repair Costs by Type

There are two general types of heat pumps - air source and geothermal. Air source heat pumps take heat from the air and compress it, moving it into or out of your home. They are central with air ducts or ductless.

Geothermal systems take heat from the ground to warm your house and deposit heat back into the ground from your home to cool it. They may also use groundwater or a lake if there is one on your property.

Because geothermal systems have buried tubing, this rarely needs repair. In most instances, the only repairs you may need are for the compressor or air handler.

Air source heat pumps have an extra outdoor component, which means that they may need repair more frequently than geothermal heat pumps. They use the same indoor components, so both types have similar cost ranges for repair. The only minor differences are if the geothermal unit needs new tubing or the outdoor component freezes. Even then, for the most part, costs between the two types tend to be fairly comparable, with most of the costs dictated by things like the unit brand or size, rather than its type.

Exterior Obstructions or Blockages

Because part of your heat pump is located outside, there are times when the condensate line or pump is blocked, which stops the pump from working. Clearing the obstruction, pump, and drain line may solve the problem. This has a cost range of $80 - $150 on average.

Heat Pump Leaking

If you find that you need to recharge your refrigerant, it might be because of a leak. In this case, you may need to have your coils replaced. Sometimes, the coils are fine, and a slow leak may be resolved with a recharge. Costs for fixing this problem are between $90 - $610.

Heat Pump Will Not Defrost

If your air source heat pump does not defrost, it might be because of a broken circuit board, or it may need more refrigerant. In either case, the cost range is $90 - $650.

Cool Air Blows

There are numerous reasons for blowing cold air, from a faulty thermostat to a broken capacitor. There is a wide range of associated costs for fixing this problem, ranging from $140 - $1,250.

Faulty Thermostat Wiring

If your thermostat is not wired properly, it will not work correctly. Sometimes, it may be rewired, but the most common solution is a new thermostat, which costs $145 - $230.

Defective Programmable Thermostat

Programmable thermostats may be defective or simply stop working over time, which means that your heat pump will not work either. If this happens, replace it for a cost of $145 - $230.

Heat Pump Not Coming On

Your heat pump may not turn on for various reasons, including a faulty thermostat or a broken breaker or fan switch. Fixing this issue has an average cost of $145 - $400.

Reversing Valve Stuck

If your reversing valve gets stuck, then your heat pump has trouble maintaining the temperature. This means you need to replace it for $200 - $650.

Heat Pump Stuck in Defrost Mode

If your defrost circuit board on an air source pump malfunctions, it may end up stuck in defrost mode. This means that your heat pump does not run. To solve it, you need to replace the board at a cost of $200 - $650.

Heat Pump Reversing Valve Noise

If your reversing valve makes a noise, this is a sign that it is likely about to fail and needs replacing. Expect a cost of between $200 - $650.

Temperature Problems

If you have uneven temperatures within your home, you probably have problems with the dampers on your ducts, or your ducts may need to be sealed. This costs $450 - $750 to fix.

Problems with the Ductwork

Ductwork problems include leaking air, rust, or complete failure of the system. If this is the case, you may need to seal them or replace them entirely at a cost of between $750 and $3,300.

Compressor Does Not Run

Without a compressor, your heat pump cannot effectively heat the air in your home. If it stops running, it likely needs to be replaced at a cost of $1,500 or more.

Blower motor$250 - $950
Evaporator coil$600 - $1,250
Condenser coil$650 - $1,500
Compressor$1,500 +

Fan Breaker Replacement Cost

The fan on your heat pump uses a breaker to regulate and keep it running properly. If this breaks, the fan stops. The cost of replacing the breaker is around $80 - $200, depending on the type of pump.

Pressure Switch Replacement Cost

Your pressure switch is also an integral part of the heat pump. Without it, your pump may stop running. Replacing the switch costs between $90 - $250 on average.

Capacitor Replacement Cost

The capacitor is not a big part of the heat pump, but it is an essential one, as well as something that wears out and needs replacement. The cost to replace it is $150 - $250.

Contactor Replacement Cost

The contactor is another small part that is essential to the heat pump’s operation. If it fails, replace it at a cost of $150 - $300.

Reversing Valve Replacement Cost

The reversing valve opens and closes, wearing out over time. If this happens, have it replaced for a cost of $200 - $650.

Heat Pump Fan Motor Replacement Cost

Your fan’s motor is something that wears out over time, often before the rest of the pump. The cost to replace the motor averages $250 - $650.

Heat Pump Motor Replacement Cost

Your heat pump also has a blower motor that is integral to its operation. Without this, the air handler is unable to do its job. If the blower motor fails, it has a replacement cost of $250 - $950.

Evaporator Coil Replacement Cost

The evaporator coil is one of the bigger parts of an air source heat pump and is integral to its working properly. Replace it at a cost of $600 - $1,250.

Condenser Coil Replacement Cost

The condenser coil acts as the heat exchanger for the heat pump. It transfers heat from the refrigerant to your ducts to circulate through the house. Without it, your heat pump does not work properly. The cost to replace this is $650 - $1,500.

Compressor Replacement Cost

The compressor heats the refrigerant even more after it takes heat from the air or the ground. This is necessary for your heat pump to adequately heat your home. If it fails, it costs more than $1,500 to replace on average.

Cost of Refrigerant for Heat Pump

Your heat pump runs refrigerant through the lines, circulating collected heat from the air or ground. Sometimes, it may need a recharge or additional refrigerant added. The cost to recharge your heat pump is around $90 - $200, depending on how much you need.

Heat Pump Repair or Replace

If you have a geothermal heat pump, the exterior portion is designed to last 50 to 100 years before needing replacement. So, if you have a problem with the system, it is usually indoors, and the solution is almost always to repair the problem. Air source heat pumps do not last as long, and the exterior portion may fail after 10 years. The interior part lasts longer, but if the heat pump is 10 years old and beginning to have problems, you may want to replace it because newer models are available that are more energy-efficient and better at heating and cooling your home. If your it is under 10 years old, repairing is the better choice because it will keep it going for a few more years.

Emergency Heat Pump Repair Costs

If your heat pump breaks suddenly in the middle of a cold snap, you want the repair service to come out fast. Most services have an additional call out of fee of $80 to $100 in addition to the other repair costs. Some may charge more if it is the middle of the night or a holiday, up to $250 in emergency charges.

Heat Pump Troubleshooting

If your heat pump stops working, there are times when the problem is something you can solve yourself. Before you call out a technician, troubleshoot to find the source of the problem. First, ensure that your thermostat is set correctly, and that it is on and operational. Next, check to make sure that your thermostat and heat pump are both set to either “heat” or “air conditioning,” depending on the time of year. Also check the breaker to see that it is turned on properly. Check the temperature outside. It is normal for heat pumps to run nearly constantly in very hot or cold temperatures. If your heat pump runs more than usual, it might be because the temperature outside is more extreme. If you notice frost on your evaporator coil, replace the filter. Sometimes, a dirty filter causes this issue. If none of these issues are the cause of your problem or you notice a leak, damage, excessive dirt or debris, or faulty wiring, call your HVAC technician for a service appointment as soon as possible.

Enhancement and Improvement Costs

High-Efficiency Models

If your heat pump is older, you may want to replace it with a high-efficiency model. While all heat pumps are efficient, newer models save you even more money, while heating and cooling more effectively. A new high-efficiency air source heat pump costs around $10,000.

HVAC Inspection

Have your heat pump inspected and serviced regularly. This avoids unexpected repair bills by keeping the pump working optimally. The cost of an HVAC inspection is around $210 - $260.

Additional Considerations and Costs

  • If your repair is done during very hot or cold weather, it costs up to 30% more, simply because HVAC technicians are busier at these times.
  • If your heat pump is in a hard-to-reach area of your home, it takes longer to repair and results in higher bills.
  • If you have an older heat pump, it is harder to locate parts. This is one reason why older systems are more likely to be replaced.
  • The larger your heat pump, the bigger and more expensive the parts.
  • Some high-quality brand names have more expensive parts than others. Carrier, Bryant, and Lennox have parts that are usually more expensive than others.
  • If your unit is badly maintained, it may need multiple repairs. This is why good maintenance is important to the way a heat pump functions.


  • How many years does a heat pump last?

This depends on the type of heat pump. Air source heat pumps last about 12 - 15 years, and geothermal pumps last up to 100.

  • How do you reset your heat pump?

Your heat pump should have a breaker to reset it. If you cannot locate it, call your HVAC technician.

  • Should I repair or replace my heat pump?

If it is an indoor component, it is best to repair it. An outdoor component more than 10 years old should be replaced if it is an air source heat pump.

  • Why is my heat pump blowing cold air when the heat is on?

This might be a failed condenser or failed compressor, but it can be because of many different problems like the thermostat.

  • How do I know if my heat pump is working properly?

If it is heating and cooling your home without struggling or causing higher bills, it is working properly.

  • How do I know if my heat pump is low on Freon?

Your heat pump may leak refrigerant if the coils have not been cleaned in some time. If you notice the coils freezing up, this is an indicator that you need more Freon.
