Heat Pump Repair and Replacement Costs Explained

Most heat pump repairs cost $150 to $650, with an average of $400 (Fixr). Replacing a heat pump costs far more: $5,000 to $15,000 for most homeowners, with a national average of $8,350 (Fixr). The failed part, the type of heat pump and your home's size drive the price.

As of 2026, these are national ranges from published cost guides, not quotes. Use them to understand what's normal before you talk to a company.

How much does heat pump repair cost?

Fixr puts the average heat pump repair at $400, with most homeowners paying $150 to $650 (Fixr). Minor fixes like a capacitor or thermostat land at the low end. Compressor and refrigerant problems cost more.

A newer Fixr guide gives a similar picture, with an average of $410 and a normal range of $161 to $661 (Fixr).

Fixr notes that heat pump repairs cost a bit more on average than HVAC repairs in general. But because one heat pump handles both heating and cooling, it can cost less to repair overall than two separate systems (Fixr).

How does a heat pump work, and why does it matter for repairs?

A heat pump moves heat instead of making it. ENERGY STAR describes a ducted heat pump as a central air conditioner that also works in reverse: in winter it pulls heat from the outdoor air into your home, and in summer it pulls heat out (ENERGY STAR).

That means a heat pump shares most of its parts with a central AC: a compressor, two coils, fans, a capacitor and refrigerant lines. It adds a reversing valve and defrost controls for winter. So many heat pump repairs cost about the same as the matching AC repair. The ones unique to heat pumps, like the reversing valve, are covered below.

What do common heat pump repairs cost?

Here's Fixr's list of typical costs by service, from cheapest to most expensive (Fixr). Each is a national range.

A major repair on an older heat pump is often the moment to compare repair against replacement. More on that below.

What's a reversing valve?

The reversing valve is the part that makes a heat pump different from an AC. It switches the direction refrigerant flows, so the system can move heat out of your home in summer and into it in winter. Carrier says if a heat pump won't heat but cools perfectly, the reversing valve may be stuck (Carrier).

What might your symptom cost to fix?

You know what your heat pump is doing, not which part failed. These pairings are common possibilities to discuss with a technician, not a diagnosis.

• Blows cool air in heat mode, all the time. Carrier links this to a possible refrigerant leak or a stuck reversing valve (Carrier). A reversing valve replacement runs $350 to $700 (Fixr).
• The outdoor unit hums but the fan won't spin. A failed capacitor is a common cause and one of the cheaper fixes, at $100 to $400 (Fixr).
• Heavy ice that won't clear. Restricted airflow, low refrigerant or a defrost control problem are common causes. A refrigerant leak repair runs $200 to $1,500 (Fixr).
• Weak or no airflow indoors. Fixr says this is likely an air handler issue (Fixr). A blower motor replacement runs $300 to $1,000 (Fixr).
• Short cycling, turning on and off quickly. Fixr lists this as a sign your heat pump needs repair, especially in extreme weather (Fixr). Causes range from a dirty filter to a control or refrigerant problem.
• Water around the indoor unit. A clogged drain line is a common cause. Drain line cleaning runs $75 to $300 (Fixr). Turn the system off and keep water away from wiring.
• Rising electric bills with no change in use. Fixr says a heat pump working harder to make up for a failing part shows up as higher energy costs (Fixr).

Can you repair a heat pump yourself?

Beyond changing the filter and keeping the outdoor unit clear, most heat pump repairs belong with a professional. Fixr says the work involves electrical components and refrigerant lines, and mistakes raise the risk of fire and electric shock (Fixr). It also notes most manufacturers will void the warranty if you do your own repairs.

Refrigerant work is regulated. The EPA says Section 608 certification is required to recharge appliances, and refrigerant for home systems is only sold to certified technicians or the companies that employ them (EPA). If a quote includes refrigerant, it's fair to ask whether the technician holds that certification.

Does the type of heat pump change the repair cost?

Yes. Accessibility is the main reason. Fixr lists these average repair ranges by type (Fixr):

• Ductless mini-split: $100 to $1,500 (Fixr)
• Air-source: $150 to $1,600 (Fixr)
• Geothermal: $200 to $2,000 (Fixr)
• Hybrid (dual fuel): $200 to $2,500 (Fixr)

Fixr explains that mini-split parts are easy to reach, while geothermal parts buried in the ground can cost thousands to expose. Hybrid systems pair a heat pump with a furnace, so they can be harder to diagnose.

What changes the price of a heat pump repair?

Labor and the service call

Fixr says every repair visit comes with a flat call-out fee of about $75 to $250, which often serves as the diagnostic fee too (Fixr). If the job takes longer than an hour, you may pay $75 to $150 per hour on top (Fixr).

Season and urgency

Fixr notes HVAC companies are busiest in summer and winter, so labor can cost more then. Rush fees for same-day, evening, weekend or holiday service add more (Fixr).

System size and brand

Larger heat pumps have larger, pricier parts. Fixr also says some brands have more expensive replacement parts than others (Fixr).

Age, condition and climate

Older units cost more to fix because parts are harder to find and major components are more likely to fail. Fixr gives heat pumps an average lifespan of 10 to 15 years, and notes that heavy use in extreme climates speeds up wear (Fixr).

Warranty

If your heat pump is still under warranty and the problem is covered, you might pay little or nothing. Some warranties cover parts but not labor (Fixr). Check before you schedule a non-emergency repair.

Is it really broken? What you can check first

Some heat pump behavior looks like a problem but is normal. Carrier lists the most common causes of a heat pump not heating as an incorrect thermostat setting, a tripped circuit breaker or a dirty air filter (Carrier).

Normal behavior

• Short bursts of cool air in winter. Carrier says a heat pump often enters defrost mode to melt ice on the outdoor unit, which is normal (Carrier). A typical defrost cycle lasts about 5 to 10 minutes.
• Light frost on the outdoor unit. Carrier says a light frost layer, generally less than a quarter inch, is normal and should clear during defrost.

Safe checks

1. Thermostat. Make sure it's set to heat or cool, not "fan on" or the wrong mode. ENERGY STAR suggests avoiding Auto mode so the system doesn't switch modes on unseasonable days (ENERGY STAR).
2. Air filter. A clogged filter can make the system blow lukewarm air or shut down. Carrier recommends checking it every 60 to 90 days (Carrier).
3. Power. The indoor and outdoor units usually have separate breakers. If one keeps tripping after a reset, leave it off and call a pro.
4. Outdoor unit. Clear leaves, snow and plants. Carrier suggests at least 24 inches of clear space as a general guideline (Carrier).

Signs it needs a technician

• Heavy ice thicker than a quarter inch, or ice that stays after defrost. Carrier says this can point to restricted airflow, low refrigerant or a defrost problem.
• Cold air all the time in heat mode, which Carrier links to a possible refrigerant leak or reversing valve problem.
• Grinding, squealing or banging from either unit.
• Burning smells, smoke or sparks. Turn the system off at the thermostat. If you see smoke or flames, leave the house and call 911.

If your outdoor unit stops working in winter, Carrier says you can switch the thermostat to "emergency heat" to use the backup heat source, but to use it sparingly because electric resistance heat can raise your electric bill significantly (Carrier).

How much does a new heat pump cost?

Fixr says heat pump installation costs $5,000 to $15,000, with a national average of $8,350 (Fixr).

By type

• Ductless mini-split: $2,000 to $8,000 (Fixr)
• Air-source (ducted): $5,000 to $15,000 (Fixr)
• Geothermal: $15,000 to $35,000 (Fixr)

By home size

Fixr gives these typical costs by home size (Fixr):

• 1,000 square feet: $5,000 to $8,000 (Fixr)
• 1,500 square feet: $6,700 to $14,000 (Fixr)
• 2,000 square feet: $8,000 to $20,000 (Fixr)
• 2,500 square feet: $9,500 to $22,000 (Fixr)
• 3,000 square feet: $15,000 to $25,000 (Fixr)

Square footage is only a starting point. A load calculation, often called a Manual J, sets the right size based on insulation, windows, climate and more. Fixr recommends always having a professional do one (Fixr).

By efficiency

Heat pumps carry two ratings. SEER2 measures cooling efficiency, and HSPF2 measures heating efficiency. Since 2023, new split heat pumps must reach at least 14.3 SEER2 and 7.5 HSPF2 in every region (Trane). Fixr lists these average costs by efficiency (Fixr):

• 14 to 15 SEER2: $5,000 to $12,000 (Fixr)
• 16 to 17 SEER2: $7,000 to $15,000 (Fixr)
• 18 to 19 SEER2: $10,000 to $18,000 (Fixr)
• 20 SEER2 and up: $15,000 to $25,000 (Fixr)

Other costs in a quote

• Labor: Fixr says labor averages $75 to $125 per hour and usually includes removing the old unit, installing the new one and refrigerant lines, electrical connections and testing (Fixr).
• Permits and inspections: these add $50 to $300 on average (Fixr).
• Ductwork: existing ducts may need repair or sealing, which adds to the cost but can lower bills.
• Backup heat: in cold climates, ask whether the quote includes electric backup heat or keeps your furnace as a backup.

How long does a heat pump last?

Fixr says heat pumps last an average of 10 to 15 years, and some last 20 to 25 years with regular maintenance (Fixr). Your home's size, whether the system was sized correctly, and your climate all affect how long yours will run.

A heat pump works year-round, heating in winter and cooling in summer. A furnace only runs in the cold months and an AC only in the warm ones. That extra running time is part of why heat pumps don't usually last as long as furnaces. Fixr makes the same point, noting a heat pump's 10 to 15 year lifespan is shorter because it runs year-round for both heating and cooling (Fixr).

Should you repair or replace your heat pump?

Fixr says repair is usually the better choice if your heat pump is less than 10 years old, hasn't given you ongoing trouble, and the problem is relatively minor (Fixr). Replacement makes more sense if the system is near the end of its life, keeps having problems, or needs a major part like the condenser or a coil.

ENERGY STAR suggests considering replacement when a heat pump is more than 10 years old (ENERGY STAR). Fixr gives two rules of thumb:

• The 50 percent rule. If a single repair costs more than half the price of a new unit, replacement is usually the better investment (Fixr).
• The age-times-cost rule. Multiply the system's age in years by the repair estimate. If the result is over $5,000, replacement is likely the better option (Fixr).

Refrigerant is another factor. Older heat pumps may use R-22, which hasn't been made or imported in the U.S. since January 1, 2020 (EPA). You can still service an R-22 system, but a leak gets expensive. The refrigerant type is usually listed on the outdoor unit's nameplate. See refrigerant leak repair costs for what those repairs run.

Is a heat pump worth it compared to a furnace and AC?

If you're replacing both your furnace and AC, a heat pump can cover both jobs. Fixr compares an average heat pump installation of $8,350 with an average furnace installation of $4,800 plus a central AC at $5,000 to $12,000 (Fixr).

Efficiency is the other draw. ENERGY STAR says a heat pump can deliver up to three times more heat energy to a home than the electrical energy it uses (ENERGY STAR). ENERGY STAR certification for cold-climate models includes testing at temperatures down to 5°F.

There are tradeoffs. Fixr notes heat pumps can lose efficiency in extreme cold and may lean on backup heat (Fixr). In very cold areas, a dual-fuel setup that keeps a gas furnace for the coldest days is worth pricing. For the AC-only side of the comparison, see AC replacement costs, and for heating repairs, furnace repair costs.

On incentives, ENERGY STAR says the federal energy efficiency tax credits ran through December 31, 2025 (ENERGY STAR). Check with your utility and state for current rebates.

How can you keep heat pump costs down?

• Schedule yearly maintenance. Fixr puts heat pump maintenance at $75 to $150, among the most affordable systems to service (Fixr).
• Change the filter on schedule.
• Keep the outdoor unit clear of plants, leaves and snow.
• Pick a temperature and leave it. ENERGY STAR says heat pumps don't save energy by being turned down when you're away, unlike a furnace (ENERGY STAR).
• Get at least three estimates for big repairs or a replacement, as Fixr recommends (Fixr).
• Check your warranty first.

What should you ask for a fair quote?

1. What's your service-call fee, and does it go toward the repair?
2. What's wrong, and how did you confirm it?
3. Is the part covered by the manufacturer's warranty?
4. Can I get the price in writing, with parts and labor listed?
5. If it's refrigerant, where is the leak, and will you fix it rather than just recharge?
6. At this age, would you repair or replace, and what's the cost difference?
7. For a new system: how did you size it, what are the SEER2 and HSPF2 ratings, and what backup heat is included?
8. Are you licensed and insured where I live? ENERGY STAR suggests checking your state's requirements and getting written, itemized estimates (ENERGY STAR).

The bottom line

Most heat pump repairs cost a few hundred dollars. Reversing valves, compressors and coils cost more, and on an older system they're often the point to price a replacement. A new heat pump typically costs several thousand dollars, and the type, size and efficiency rating explain most of the range.
