How Much Does An AC Compressor Cost?

Is your AC failing to produce cool air? Sometimes, this problem can be resolved by replacing the air filters. However, if this solution doesn’t help, you may have a more serious issue, such as a faulty AC compressor. 

The AC compressor is part of your unit’s refrigerant cycle, which helps create cool air. Anything from low refrigerant to a dirty unit can cause the device to fail. Meanwhile, the cost of a replacement can range anywhere from $800 to over $4000 depending on your unit and replacement refrigeration to recharge the unit. In this blog, we’ll go over everything you need to know about the AC compressor, including the following:

What Does the AC Compressor Do?

As mentioned above, the AC compressor is integral in producing cold air. But how exactly does it accomplish this? 

First, the AC compressor places pressure on (or compresses) the refrigerant fluid. This process increases the refrigerant’s temperature and energy. Next, the AC compressor sends the high-temperature refrigerant to the AC condenser, which releases its heat. During this process, the refrigerant becomes a high-pressure liquid.

The refrigerant is then sent to the expansion valve, which expands the fluid and turns it into a cool, low-pressure gas. Finally, the refrigerant goes through the evaporator coil, which absorbs heat from the air to help keep the home cool. 

Without the AC compressor, the refrigerant cannot complete its role. Not only does this affect your home’s comfort, but it may also cause issues such as refrigerant leaks, overheating, and poor energy efficiency.

Factors Influencing AC Compressor Cost

Now that you know what it does, you’re probably wondering: How much does an AC compressor cost? While it can cost anywhere from around $800 to $4,000, the exact answer will depend on the following factors.

Type of Compressor

There are two main types of compressors: single-stage and multi-stage compressors. Single-stage varieties operate at one speed and turn off when the desired temperature is reached. Multi-stage compressors, meanwhile, offer from two stages to full variable speed systems. This allows for better energy efficiency and temperature control. Because they’re more complex, multi-stage compressors are more expensive to replace.

AC System Size

Larger AC systems typically have larger compressors, which are more expensive to purchase.

Brand and Model

If you have a high-end AC system, the cost of parts may be higher. However, high-quality AC units typically offer longer warranties and system life spans in exchange. They’re also less likely to break down.


If your AC compressor stops working and your warranty is still valid, the manufacturer will cover part of the costs. Contact your manufacturer to find out your exact warranty period. Typically, AC compressors come with 10-year warranties.

Labor Costs

Labor costs can vary depending on the HVAC company you use. Look for a company that has a record of 5‑stars, such as the Cooper Green Team.

Tips for Avoiding AC Compressor Replacement

At the end of the day, replacing your AC compressor can be costly. Fortunately, you can take steps to reduce costs and even avoid a replacement altogether.

Don’t Accidentally Void Warranty

First, make sure your warranties remain valid. This way, you’ll receive coverage in case a problem happens. Here are some things that can void the warranty: 

  • Damaging the unit
  • Using generic or incompatible parts
  • Not receiving AC maintenance

Annual AC Maintenance

Annual AC maintenance is one of the best ways to keep your warranties valid. Furthermore, a yearly check-up helps ensure everything’s in working order. At Cooper, we offer a maintenance plan designed to improve AC functionality and efficiency while reducing long-term costs. Plans come with a 100% satisfaction guarantee, so you can trust that you’ll be happy with the service.
