A failed AC compressor is one of the most expensive AC repairs you’ll face. For a typical single-family home with central air conditioning, replacing just the compressor can cost between $1,500 and $3,000, including parts and labor.
Thank you for reading this post, don't forget to subscribe!If your AC compressor stops working, you’ll notice your home isn’t cooling properly—or at all. AC compressors tend to last between 10 and 15 years, which is about how long many AC systems last. Your system’s age, as well as your unit’s brand and whether you have a warranty, will play a big role in whether or not you should replace your compressor.
This guide will help you understand your options, including when it makes more sense to replace your entire AC system versus just the compressor. We’ve analyzed recent cost data from HVAC suppliers and interviewed experienced HVAC contractors to provide you with accurate pricing.
HVAC Installation
In general, you’ll pay between $5,540 and $10,980 for an HVAC unit, installation costs, and removal of your old unit.
Furnace Replacement
You can expect to pay between $4,000 and $7,000, including installation, old furnace removal, and labor.
Heat Pump Installation
You’ll likely pay between $3,000 and $35,000, but most homeowners spend between $5,800 and $7,500.
Average Cost To Replace an AC Compressor
Our research found that, on average, replacing an AC compressor costs $2,000. This includes the compressor and the labor required to install it. Several factors impact the total cost, including the type of air conditioner, your home’s size, and your warranty coverage.
If your home is on the smaller end, or if you have a window unit or mini-split, compressor replacement may cost under $1,000.
| Low AC Compressor Cost | Average AC Compressor Cost | High AC Compressor Cost |
| $150 | $2,000 | $3,000 |
How Does Home Size Affect AC Compressor Pricing?
You should also consider air conditioner size. Generally, the larger your home, the larger your AC compressor needs to be.
An AC compressor that will cool a 1,000-square-foot home might cost you between $1,000 and $1,500 to replace, but you could spend between $2,000 and $3,000 for a compressor that can cool your 3,000-square-foot home.
| Home Size in Sq. Ft. | Typical Cost Range |
| 600–1,000 | $700–$1,500 |
| 1,000–1,500 | $1,000–$1,800 |
| 1,500–2,000 | $1,200–$2,200 |
| 2,000–2,500 | $1,500–$2,700 |
| 2,500–3,000 | $1,700–$3,000 |
AC Compressor Costs by Types and Common Brands
It’s important to note that you can’t simply choose which type of compressor to install when replacing a failed one—your AC system is designed to work with a specific compressor type. Here’s what you need to know about the different compressor types and which brands use them.
Single-Stage Compressors ($500–$1,500)
Single-stage compressors are found in many basic and budget-friendly AC units. “These are the most common type we see in homes built before 2015,” said Tom Martinez, an HVAC technician. “They’re simple and reliable, but not as efficient as newer technologies.”
These brands commonly use single-stage compressors:
- Amana (entry-level units)
- Coleman (standard efficiency models)
- Goodman (most models under $4,000)
- York (basic models)
Two-Stage Compressors ($1,000–$2,500)
Two-stage compressors represent a sweet spot between efficiency and cost. They’re becoming the standard in midrange units, especially in variable climate regions.
Models from these brands feature two-stage compressors:
Variable-Speed Compressors ($2,000–$3,000)
These are the most advanced compressors, found primarily in premium AC systems. Variable-speed technology is the gold standard for efficiency, but it comes at a price.
These brands use variable-speed compressors:
- Daikin (VRV systems)
- Carrier (Infinity series)
- Lennox (Signature series)
- Trane (XV series)

Which Other Factors Affect AC Compressor Cost Estimates?
How much a new AC compressor costs mainly depends on its size, but it can also depend on the brand, air conditioner type, and warranty, as well as any additional costs. As you gather quotes, pay attention to these factors to save the most money on your new compressor.
Air Conditioner Type
If you can’t decide whether to replace your air conditioner or just your compressor, consider what type of air conditioner you have. On average, home AC compressors for central air conditioners and heat pumps are the most expensive, while mini-split and window air conditioners are the least expensive.
| Air Conditioner Type | AC Compressor Low Cost | AC Compressor High Cost |
| Window unit | $150 | $700 |
| Mini-split | $600 | $2,200 |
| Central air | $800 | $2,700 |
| Heat pump | $800 | $3,000 |
- Window AC: Compressors for window AC units can cost between $150 and $700. This is almost equal to the price of a completely new window air conditioner. We recommend you buy a new AC unit if your window AC compressor fails.
- Mini-split: To replace a mini-split air conditioner compressor, the labor and parts generally cost between $600 and $2,200. If you have several zones or larger units, replacing your mini-split instead of only the compressor may be more worth it.
- Central air: Central air system installation costs between $3,080 and $5,965. You can expect to pay between $800 and $2,700 to replace your central AC compressor—or about 25%–45% of the total system cost. Replacing your compressor may be a reasonable stopgap in this case.
- Heat pump: For a heat pump, AC compressor replacement costs between $800 and $3,000 on average. Because these air conditioning systems are the most expensive to install, it may be worth it to replace the compressor.

Warranty
When you purchase a new air conditioner, it comes with a limited parts or manufacturer warranty that often covers the cost of a replacement AC compressor. Most warranties last five or 10 years, so if your compressor breaks during this period, you should contact the manufacturer to potentially save hundreds (if not thousands) of dollars.
Unfortunately, these warranties don’t usually cover labor costs unless the compressor broke due to manufacturer defects, so you will still need to pay $300–$600 to have the new compressor installed.
If you don’t have a manufacturer warranty, buying one of the top home warranties for your air conditioner can help you save money. Although you’ll pay a monthly premium, typically between $45 and $65, most home warranty companies will cover the labor and parts to fix the compressor, or even the cost of replacing your condensing unit.
Additional Costs
The total cost of your new air conditioner compressor will often factor in more than just the compressor. Typically, you’ll pay more for labor and other small tasks during this replacement. Some of the most common additional costs include:
- Labor costs: Most AC compressor replacements take about four hours to complete, but you may pay more labor costs if you have a complex repair job. Labor costs vary from state to state and even from one ZIP code to the next, so estimating your exact labor cost is difficult. Typically, you can expect to pay a minimum of $75–$150 per hour or $150–$600 total.
- Refrigerant: HVAC technicians often refill your refrigerant or Freon when they repair your AC system. You can expect to pay between $100 and $350 for a refrigerant refill.
- Repairs: If you can repair your compressor instead of a full replacement, you can save hundreds of dollars. AC compressor repair costs between $75 and $300 in labor.
- Thermostat: A new programmable thermostat can help you save money on energy costs and make your home more energy-efficient. For a new thermostat, you’ll pay between $100 and $300 on average.

Should You Replace Just the Compressor or Get a New AC System?
When your AC compressor fails, you must decide whether to replace the compressor or buy a new AC system. Below is advice based on our research and conversations with HVAC professionals:
Replace just the compressor if:
- Your AC unit is less than 7 years old
- The compressor is still under warranty (most manufacturers offer 10-year parts warranties)
- The rest of your system is in good condition and well-maintained
- You have a newer, energy-efficient system
Consider a new AC system if:
- Your AC is over 10 years old
- The compressor isn’t under warranty anymore
- You’re facing high energy bills from an inefficient system
- You’ve had other recent repairs
“When a compressor fails on an older unit, replacing the entire system almost always makes more financial sense,” said Mike Rodriguez, an HVAC contractor with 20 years of experience. “The compressor alone can cost up to $2,500, while a new energy-efficient system might run $3,500 to $5,500. The minimal price difference often justifies the upgrade,” Rodriguez added.
Labor costs should play a role in this decision, too. Installing a new compressor takes between four and six hours of skilled labor, but you may still have an older system with other aging components. A complete system replacement might take longer but it provides you with all new parts and a fresh warranty.
Professional Vs. DIY AC Compressor Installation
Air conditioners are complex systems, so you can’t just remove the old compressor and bolt in a new one. Not only do you have to flush out the old system, but you also have to know how to handle refrigerant, use the right type of oil, prevent debris from blocking the compressor, and much more. Installing an AC compressor is very complex—and, therefore, best left to the professionals.
Installing an AC Compressor Yourself
AC compressor installation isn’t a good DIY project, so you shouldn’t try to install this part yourself. If you do, you may not install it properly, which can further harm your entire air conditioning system.
Working with an HVAC pro comes with several benefits, especially if you want to rely on warranty coverage should something go awry:
- You’ll get a workmanship warranty to cover any problems with the installation.
- You’ll have manufacturer warranty coverage because your compressor is installed correctly.
- You’ll have the knowledge that your compressor needs to be replaced and not repaired.
- You’ll have an HVAC company that can come to your home and knows your system.
- You can get regular HVAC tuneups and maintenance done.
Hiring a Professional for AC Compressor Installation
Because AC compressor replacement isn’t an easy DIY project, you should hire a professional HVAC installer to do the job. Follow these simple steps to connect with the best HVAC contractors in your area and have your AC compressor installed quickly:
- Find local experts near you: Use the button below to be connected to the best HVAC technicians in your area.
- Get a quote from a few options: Because labor costs and brand costs vary so wildly, you should always gather at least three different quotes to compare the cost and types of compressors.
- Consult pros about their recommendations: Ask the HVAC technician if they believe you should replace your air conditioner, replace the compressor, or if HVAC repairs would do the job.
- Choose a quote: With your budget and needs in mind, choose the estimate that makes the most sense for your home.
- Install your AC compressor: Work with your HVAC technician to schedule the best time to replace your compressor so that your air conditioning unit is up and running as soon as possible.
Our Recommendation on AC Compressor Replacement Costs
The compressor is the heart of your air conditioner and one of the most important parts that’s responsible for cooling your home. When it breaks down, you’ll want it fixed immediately to avoid rising temperatures and potentially damaged AC equipment.
An AC compressor usually costs between $1,500 and $3,000 to replace, with an average of $2,000. This total cost depends on factors such as the type of compressor and AC, brand, your home’s size, and labor costs. You should thoughtfully consider whether it’s worth it for you to replace your AC compressor.
In many cases, it’s only worth getting a new AC compressor if it’s still under warranty. If you have to pay for a new compressor out of your pocket, you might as well buy a new air conditioner, as it won’t be much more expensive.
FAQs About AC Compressor Cost
Why is it so expensive to replace an AC compressor?
An AC compressor is expensive to replace because it takes at least four hours to complete, and replacement parts are among the most expensive parts of the air conditioner. In many cases, replacing the entire air conditioning system is more cost-effective than just replacing the compressor.
How long does an AC compressor last?
A well-maintained compressor typically lasts 10-15 years, which is about the same lifespan as your AC unit itself. However, several factors can shorten its life, including electrical storms, poor maintenance, frequent short cycling, or operating with incorrect refrigerant levels.
In regions with extreme heat or where AC systems run almost year-round, compressors might need replacement sooner.
How do I know if my AC compressor is bad?
Warning signs of a failing compressor include unusual noises (particularly grinding or squealing), warm air coming from your vents, frequent circuit breaker trips, or your system struggling to start up. If you notice any of these signs, having an HVAC professional inspect your system early can sometimes prevent complete compressor failure or help you plan ahead for the eventual replacement.
Regular maintenance plays a huge role in compressor longevity. Simple steps such as keeping the outdoor unit clean, ensuring proper airflow, and scheduling annual professional maintenance can add years to your compressor’s life.
Is it all right to just replace the AC compressor?
Replacing the compressor and not the entire air conditioning system is perfectly OK. Replacing an AC compressor is similar to replacing a car’s engine—you can do it, but it can be expensive if the compressor is no longer under warranty.
What are the benefits of replacing an AC compressor?
If a manufacturer’s warranty still covers your air conditioner and components—or if you have a home warranty plan covering your AC compressor—then it’s worth replacing only the AC compressor so you won’t have to buy an entirely new outdoor unit. This new AC compressor will save you money and cool your home more efficiently.
