Heat Pump Repair & Maintenance Costs

Heat pump repairs cost an average of $389. You’ll typically pay $159 and $620 but you might pay as little as $65 or as much as $1,400 including parts and labor. Most pros charge a minimum trip fee, often equal to the first hour or two of work, or $75 to $150. Annual maintenance checks and inspections run $75 to $150.

Energy-efficient heat pumps can both heat and cool homes and commercial buildings. They operate by transferring heat energy from one location to another. Although efficient at regulating indoor temps, they can break down. This guide covers all the cost factors in estimating the cost to repair a heat pump. Below is a look at the different types of heat pumps and how to address the most common problems that affect them.

Repair Costs for Common Heat Pump Problems

Repairs cost anywhere from $100 to $1,000 for the most common problems. These include temperature problems (the heat pump fails to sufficiently heat or cool a home), the tendency for it to "ice up" or "freeze up", and the failure to blow warm air when the unit is in heating mode.

Other signs of malfunction include strange noises and constant operation. As outlined below, most of these problems stem from defects within a heat pump's thermostat or condenser, or from your home's ductwork.

Thermostat/Temperature Repair Costs

Thermostat repairs cost $100 to $300. Replacement can run upwards of $700 if you need a new smart home integrated model. Always check your thermostat first when your system acts up. Thermostat-related problems typically fall into the following three categories:

  • Faulty thermostat wiring: $100-$200. This is the least expensive thermostat-related repair because you are not replacing the thermostat in its entirety.

  • Defective standard thermostat: $150-$300. If replacing your thermostat’s wiring fails to alleviate your thermostat problems, you may need a new thermostat.

  • Defective programmable thermostat: $300-$700. This is the costliest type of thermostat problem because programmable thermostats are more expensive and take approximately one hour longer to install. Return to Top

Condenser Replacement Cost

Condenser repairs cost $150 to $1,000 to repair. Replacement runs $900 to $2,000. Like standard air conditioning units, heat pumps have outdoor condenser systems. Several common repairs you’ll most often come across include:

  • Exterior Obstructions or blockages: You should get a yearly tune up. Annual HVAC maintenance costs $75 to $200. During this, your pro will clean around your coils. But if you simply have snow or leaves blocking your unit, you can carefully dig and clean around it.

  • Interior blockage: You’ll need to replace the unit.

  • Refrigerant replacement costs: $100 to $350. Low refrigerant levels lead to inefficient heat transfer.

  • Worn or damaged defrost control boards: $150-$600. If your unit is “icing up” with increasing frequency, you may have a faulty defrost control board.

  • Faulty timer motors: $200-$250. Older model heat pumps contain timer motors that control the defrost mechanism.

Ductwork Repairs

Repairing ducts costs $250 to $700 on average but you might pay $2,000 or more. Replacement averages $35 to $55 per linear foot. Exact costs depend on the extent of the damage, but typically it’s much cheaper than replacing the whole unit. Common ductwork-related problems include poor air flow, condensation, and odd noises. These problems tend to be the result of the following:

Heat Pump Repair Costs By Type

Heat pump repair costs range from $100 to $2,000 depending on the type you have and the extent of the damage. Heat pumps are categorized according to the source of energy used. Factors to consider when choosing a pump include your location, climate and budget.

Air Source Traditional$200-$1,600
Ductless Mini Split$100-$1,500
Water Source$200-$1,800

Air Source

The most common type of heat pump is an air source that costs between $200 and $1,600 to repair. It works by pulling heat from the air. They work better in temperate climates without extremes in temperature. Air source heat pumps have been used for decades in all regions of the United States. In extreme areas, they’re often used with a backup heat source, like a wood stove or baseboard heat.

  • Advantages: Low installation costs, easy to access for repairs

  • Limitations: Not the best choice for extreme climates

Mini-Split Ductless System

Mini-split systems, a type of ductless air source heating and cooling, cost about the same as any other type to repair at $100 to $1,500. They cost more to install than a traditional unit. Ductless heat pump installation costs $1,300 to $8,000 on average.

  • Advantages: Energy efficient and compatible with homes without duct work.

  • Limitations: Higher than normal installation costs and doesn’t work well in extreme climates.


Geothermal pumps cost $200 to $2,000 to repair. They draw energy from deep within the ground where temperatures tend to say more consistent and warmer. They are dependable and may reduce energy use by up to 60%. Great for all climates and with different configurations for most types of soil and locations. A popular option for those looking for the lowest operating costs and environmental impact, they cost the most to install at $6,000 to $30,000 or more.

  • Advantages: Compatibility with extreme climates, high energy efficiency

  • Limitations: High installation costs, difficult to access for repairs

Water Source

Water source unit fixes cost $200 to $1,800. This type uses pipes laid at the bottom of a body of water, like a lake or pond. They tend to be more costly to install but are less expensive to operate. Water source heat pumps are the least common type because many people lack access to a nearby body of water or find local regulations stop them from using a nearby water source.

  • Advantages: Low operating costs, high energy efficiency

  • Limitations: High installation costs; often not an option for people located in land-locked areas Return to Top


How does a heat pump work?

Heat pumps work by pulling heat from an outdoor source (the air, the ground or a body of water) to warm your home. They can also keep your home cool during the summer by pushing warm air outside if you have a two-way heat pump system.

What are the main components of a heat pump?

There are four main components of a heat pump:

  1. Compressor

  2. Condenser

  3. Expansion valve

  4. Evaporator

How much does it cost to replace a heat pump?

Replacing a heat pump costs anywhere from $4,000 to $7,000 on average. Air source models cost half as much as geothermal or water sourced types.

What are the primary alternatives to heat pumps?

The primary alternatives to a heat pump include:

Are heat pumps expensive to maintain?

No, heat pumps are relatively affordable to support. An annual service call averages $150 to $200. Most specialists recommend annual tune ups to keep it running well.

Will an air source heat pump work for me if I live in a cold environment?

Newer air source heat pumps can work in single-digit temperatures. However, it’s best to have a backup heat source, like baseboard heating, pellet stoves or even a fireplace for cold snaps. New ductless models and Cold Climate Air-Source Heat Pumps work well in colder environments.

Does a heat pump operate as well as a furnace?

Heat pumps run more efficiently than furnaces, but don’t heat as quickly. Heat pumps are also more energy-efficient and cheaper to use.

Can I install a heat pump in a home that is currently using a furnace?

You can install a heat pump in any home that already has a furnace, air ducts or any type of forced air circulation system.

What is the average lifespan of a typical heat pump?

The Air Conditioning, Heating & Refrigeration Institute (AHRI) indicates the average heat pump is designed to last about 14 or 15 years. Newer models can last 20 years or more.

What qualities should I seek in a heat pump repair company?

The qualities to look for in a heat pump repair provider should be professional, accessible, and able to offer plenty of customer references. Your provider should have several years of industry experience, familiarity with all three types of pumps, and keep replacement parts at the ready.
