An air conditioner (AC) compressor circulates and compresses refrigerant throughout your air conditioner — but when it breaks down, the airflow in your home will be anything but cool. The compressor is an expensive part of your air conditioner, so it’s up to you to determine if it’s worthwhile to replace it.
To ensure you have the most accurate cost information, we use actual construction material databases, talk to HVAC installation experts, and gather quotes from the best HVAC installers. We’ve done the work, so you don’t have to — so let’s learn just how much an AC compressor costs.

In general, you can expect to pay between $3,000 and $35,000, but most homeowners spend between $5,800 and $7,500.
GET ESTIMATESThe cost to replace an AC compressor ranges between $150 and $3,000, with an average total cost of $1,600. This cost includes the compressor and the labor required to install it. Several factors impact the total cost, including the type of air conditioner, the size of your home, warranty coverage, and more.
Low AC Compressor CostAverage AC Compressor CostHigh AC Compressor Cost$150$1,600$3,000The type of compressor you have is just one factor that can affect the cost of replacing it. There are three types of compressors: single-stage, two-stage, and variable-speed.
Type of CompressorLow CostHigh CostSingle-Stage Compressor$250$1,200Two-Stage Compressor$1,000$2,000Variable-Speed Compressor$1,500$3,000Single-stage compressors are the least expensive type, and therefore the cheapest to replace. These compressors have only one speed — so even though they’re more affordable to replace, they are less efficient overall. You can expect to pay between $250 and $1,200 to replace a single-stage compressor.
Two-stage compressors are more efficient than single-stage compressors because they can run at 60% to 70% capacity after the air in your home reaches the set temperature. The average cost to replace a two-stage compressor is $1,000 to $2,000.
Variable-speed compressors are the most efficient type of compressor because they can operate between 0% and 100% capacity — but they’re also the most expensive to replace. You should expect to pay between $1,500 and $3,000 to replace such a compressor.
Air conditioner size is an important factor to consider. Generally, the larger your home, the larger your AC compressor needs to be. Typically, it takes about 20 British thermal units (BTUs) to cool 1 square foot. So if you have 2,000 square feet of living space, you’d need about 40,000 BTUs to effectively cool that area.
For instance, a 2-ton AC compressor that will cool a 1,000-square-foot home might cost you between $700 and $1,500 to replace, but you could spend between $1,700 and $3,000 for a 5-ton compressor that can cool your 3,000-square-foot home.

Most of this wide span depends on AC compressor size, but several other factors can increase your total cost if you aren’t careful. As you gather quotes, pay attention to these factors, and you can save the most money on your new compressor:
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.

You may not be able to control compressor size, but you have a say in your chosen brand. Air conditioner brands such as Amana and Coleman offer AC compressors that cost up to $1,200 and $1,500, respectively, but other brands — like American Standard and Carrier — charge up to $2,200.

Most warranties are five or 10 years, so if your compressor breaks during this period, you should contact the manufacturer because it can save you hundreds (if not thousands) of dollars.
The one downside is that these warranties don’t usually cover labor costs unless the compressor broke due to manufacturer defects, so you will still need to pay $300 to $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 is another way to save money. Although you’ll pay a monthly premium 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. A home warranty is the way to go if you want to save money.
The cost of your new air conditioner compressor is often more than just the compressor itself. Frequently, you’ll pay more for labor and other small tasks during this replacement. Some of the most common additional costs include:

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.
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.
There are several benefits of working with an HVAC pro, especially if you want to rely on warranty coverage should something go awry:
Because AC compressor replacement isn’t the easiest 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:

The AC compressor is the heart of your air conditioner and one of the most important parts responsible for cooling your home. When this important part breaks down, you want it fixed immediately.
An AC compressor costs between $150 and $3,000 to replace. This total cost depends on the type of compressor, brand, size of your home, and labor costs. You should thoughtfully consider whether it’s worth replacing the AC compressor — in most 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 — because it won’t be much more expensive.
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 the compressor.
Most AC compressors have a lifespan of 10 to 15 years. With proper annual maintenance for your air conditioning system, your AC compressor should run well for its entire life.
If your AC unit runs but doesn’t cool your home, emits warm air, makes strange noises, or leaks, your air conditioning compressor may need to be replaced. These are the most common signs of a bad AC compressor, and you should call your local HVAC contractor to check it out.
Replacing the compressor and not the entire air conditioning system is perfectly OK. Replacing the AC compressor is similar to replacing the engine in a car — so you can do it, but it can be expensive if the compressor is no longer under warranty.
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 because you won’t have to buy an entirely new outdoor unit. This new AC compressor will save money and cool your home more efficiently.
The HVAC compressor pumps refrigerant through the air conditioning system and performs the initial step in the cooling process. Refrigerant is the substance that cools the air in the house by absorbing heat and humidity. Most people are familiar with the refrigerant brand Freon, although it’s being phased out of use.
Refrigerant that has absorbed heat from the home’s air at the evaporator coils flows outside to the compressor. At this point, the refrigerant is a warm, low-pressure vapor. The compressor applies energy until the refrigerant becomes a hot, high-pressure vapor. The refrigerant must be heated to a temperature higher than the outside air to release heat as it travels through the condenser’s coils. Pressurization allows the refrigerant to flow smoothly through the coils.
