Heating and air conditioning service costs depend on your project and location. Check with a local pro for your specific job.
Professional AC compressor installation costs between $800 and $2,300, with your total determined by compressor size, type, and brand selection.
Your AC tonnage sets compressor size, and higher-capacity systems need larger parts that raise your project cost.
Plan for refrigerant refills of $150 to $350 for leaks, plus fees for warranty checks and scheduling.
Hiring local air conditioning repair professional prevents electrical hazards and refrigerant leaks, and ensures your installation meets building codes.
On average, AC compressor costs range from $800 to $2,300, with most folks paying $1,200 for a new one. However, your price will vary depending on factors like the size and brand of your compressor. Before you schedule your replacement, read on to learn about all AC compressor cost factors.
Important factors that influence your AC compressor replacement cost include the size, brand, and type of compressor you choose to purchase.
Manny was very trustworthy and professional. He gave me a very fair price. Within 24 hours he had done his inspection and given me an estimate. It's the first time I talked to an HVAC company that didn't make me feel like I was getting overcharged. One of the other companies I spoke to was trying to charge 6 times the cost. He took lots of pictures and video and explained step by step what was done wrong by the other contractors and what he would need to do to fix it. He was able to do the work the day after I accepted the estimate. He completed all the work in one day. I am confident and very relieved to say that my HVAC system is set up properly.
Tonnage and British Thermal Units (BTUs) work together to measure the size and capacity of an AC—and therefore, also the compressor inside of it.
Determining your AC tonnage measures how much heat your AC can cool in one hour. On the other hand, a BTU measures how much energy the AC uses to remove heat per hour. A central air conditioner system typically measures between one-and-a-half and five tons and between 18,000 and 60,000 BTUs depending on the size of your home.
Here's a bit of quick math as an example. Each ton of AC capacity cools 12,000 BTUs. And since you need about 200 BTUs to cool each square foot of space, a three-ton AC will cool an 1,800-square-foot home.
Bring the two methods together, and you can determine the size and efficiency of your unit as well as the cost of the compressor. On a basic level, the larger your AC in tons, the larger the compressor, and the higher the cost.
Here are some examples.
| AC Tons | BTUs | New Compressor Price Range |
|---|---|---|
| 1.5 | 18,000 | $700–$1,300 |
| 2 | 24,000 | $800–$1,400 |
| 2.5 | 30,000 | $900–$1,600 |
| 3 | 36,000 | $1,000–$2,100 |
| 3.5 | 42,000 | $1,100–$2,200 |
| 4.0 | 48,000 | $1,200–$2,100 |
| 4.5 | 54,000 | $1,300–$2,300 |
| 5.0 | 60,000 | $1,800–$2,600 |
There are five primary types of compressors, each with its own method of cooling warm air as well as its own price tags. You can also choose from single, two-stage, or variable-speed compressors depending on your type of AC.
| AC Compressor Type | Average Cost |
|---|---|
| Centrifugal | $1,600–$2,400 |
| Scroll | $500–$1,500 |
| Reciprocating | $400–$1,000 |
| Rotary | $50–$100 |
| Screw | $300–$1,200 |
Compressors will cost anywhere from $100 to $2,300 on average before labor. In some cases, you can even upgrade the type of compressor in your AC, but it is important to work with a professional AC repair team to choose the right one.
Every type of air conditioner—from window units to central air—needs a compressor to function. And as we learned above, the larger the AC, the larger the compressor. It's important to note that replacing a compressor in a small unit, such as a window or portable AC can, at times, cost more than the total of buying a new machine.
Here are the labor and material costs of AC compressors for different systems:
| HVAC System | Average Cost |
|---|---|
| Window AC | $250–$425 |
| Mini-split AC | $600–$1,000 |
| Central AC | $800–$2,380 |
Much like the classic plain white T-shirt, different AC compressor brands have different prices for similar products, with variations anywhere between $100 and $500. For example, compressors from Goodman/Amana can cost up to $1,200, while ones from York/Coleman go up to $1,500.
While name brand doesn’t always mean a product is better, it’s a good idea to look at reviews before you buy to determine if you’re getting the best deal on the AC compressor. You can likely save a bit of money by going generic, but be sure to consult a pro to see if the compressor is best for your unit.
If your old AC compressor still has a valid warranty, you might spend between $600 to $1,200 under warranty, but if the compressor you’re replacing has an expired warranty, expect to pay closer to $1,300 to $2,500.
IIf you also need to add more refrigerant to your AC unit, tack on another $100 to $350. Air conditioner freon refill costs between $300 and $960 depending on the type of refrigerant, your system, and related repairs. You will only need to refill your AC refrigerant if your system has a leak. Otherwise, the refrigerant levels do not deplete over time.
But what is freon and what do we mean by a refrigerant leak? The term freon now casually refers to the refrigerant, but it is no longer the same chemical it was 20 years ago. The Environmental Protection Agency reported that it phased out R-22 starting in 2010 and fully stopped production and imports in 2020. Nowadays, air conditioners use a range of more eco-conscious compounds, such as the R32 refrigerant.
A professional AC repair pro will be able to diagnose a broken compressor, choose the correct new part, and replace it safely. You'll pay an average of $75 to $150 an hour for AC compressor installation, or a flat fee between $300 and $900. The flat fee will cover travel fees, the initial inspection, and between four and six hours for the replacement.
Your annual air conditioner servicing will be the main ongoing expense for your AC compressor. On average, these appointments cost between $75 and $200—and they’re essential for keeping your AC in good shape and minimizing its risk of problems in the future.
By working on your HVAC system or undergoing important repairs on your own, you could void your unit’s warranty or further damage the system. Leave HVAC repairs to the pros.
When fixing any appliance, there's always the chance your technician will stumble upon related issues. Additionally, the time of year and urgency of the repair can sway the cost.
In the best-case scenario, your technician will look at your compressor and realize it only needs a small repair. In this case, you'll only pay for an hour of labor for between $75 and $150. However, if there’s a significant issue it’s often best to replace the full compressor to avoid issues in the future, particularly if it's due for an upgrade.
If there are problems beyond the compressor—or if a new compressor costs more than the AC itself, you may need to replace the whole unit. The cost of installing a new air conditioner may be as low as $150 for a DIY window unit or as high as $6,000 for a fully installed central air system.
What if you discover that you can run a more efficient AC if you opt for an upgrade? In addition to choosing a more energy-efficient compressor, you could choose to make the following part upgrades:
Cost to replace ductwork: $25–$55 per linear foot
Cost to replace evaporator coils: $600–$2,000
Cost to replace the blower motor: $300–$900
Cost to replace the thermostat: $110–$260
HVAC techs are in high demand in the summer, so you will likely pay a premium for mid-season repairs. Costs will drop in the shoulder seasons around September and March. Companies will also charge extra for rushed jobs, particularly when rushing the shipment of the new compressor. And lastly, assume a higher installation cost on weekends, holidays, and for last-minute requests.
You can save money on an AC compressor by DIY and avoiding name-brand products when you can and shopping around for a qualified pro to do the installation for you. Be sure to reach out to multiple companies and ask for estimates to ensure you’re getting the best deal.
Though you can save roughly $300 to $900 on labor by doing your AC compressor replacement yourself, you should only do so if you have the necessary experience and tools to safely remove the old compressor and install the new one.
We don’t recommend taking on this project yourself, as an AC compressor is a heavy piece of equipment that requires multiple hands on deck and could pose a safety risk if you don’t know what you’re doing. Instead, call an air conditioning repair company near you to safely replace your AC compressor.
Installing an AC compressor is a complex task that’s best left to the pros. Here’s why:
Experienced professionals know hw to prevent leaks, electrical hazards, and improper refrigerant handling.
Working with a pro ensures your project complies with local building codes and manufacturer warranty requirements.
Pros have the specialized tools and expertise needed to install a new AC compressor.
DIY installation can lead to costly repairs, inefficient systems, and even complete AC failure.
Experts complete the job safely, efficiently, and correctly the first time.
To assist with AC compressor installation, consider taking on the following tasks:
Clear the area around the unit of any debris, furniture, or landscaping that could block access.
Help your pro move or position brackets or pads for the new compressor.
Keep tools organized and easily accessible for your pro.
Clean or tidy the area after the installation is complete.
Be prepared to discuss the compressor size, type, and brand you’d like to install with your pro.
Let your pro know the size, layout, and specifications of your home so they can calculate which system is right for your needs.
Ask about potential add-ons like high-efficiency condensers, smart thermostats, or upgraded refrigerants.
Leave room in your budget for unexpected material costs, labor increases, or HVAC upgrades that may pop up during installation.
