What parts do I need for my AC compressor replacement, and how much do those parts cost?

For model-specific HVAC system information, you should consult your vehicle repair guide and

owner’s manual

. But here’s a basic breakdown of the parts you may need:

Air conditioning compressor: The replacement compressor is the primary part you’re going to replace. Compressor prices can vary based on the vehicle and whether you choose OEM or aftermarket parts. But, on average, a new AC compressor costs between $200 and $700. Recommended brands are Denso, Four Seasons, and UAC (Universal Air Conditioner).

AC accumulator/receiver-drier: This part is responsible for filtering out moisture, debris, and contaminants from your car’s AC system. Most experts recommend replacing the accumulator any time you open the AC system for repairs. A new one can cost between $20 and $100. We recommend brands like UAC (Universal Air Conditioner), Four Seasons, and ACDelco.

AC refrigerant: After you replace the compressor, you’ll need to recharge the AC system with refrigerant. Cans of refrigerant can cost $20 to $50 or more. We recommend reputable brands like InterDynamics, A/C Pro, and FJC.

AC system oil: The AC unit will require fresh oil after your replacement. This typically costs between $10 and $30. Recommended brands include FJC, InterDynamics, and UAC (Universal Air Conditioner).

O-rings and seals: You should replace the AC line o-rings and seals during your compressor replacement, especially if they are brittle or cracked. These parts are relatively cheap and should cost between $1 and $10. Three brands we recommend are Fel-Pro, Victor Reinz, and Mahle.

You can buy all these parts for your AC compressor replacement from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto. Keep in mind that the best options for your AC compressor parts will vary depending on your’s year, make, and model.

Should I buy OEM or aftermarket parts?

When it comes to automotive repairs, you should generally go with original equipment manufacturer (OEM) parts if possible—especially if you drive a newer vehicle.

OEM parts are designed specifically to fit your car. They are made from high-quality materials and come with a strong manufacturer’s warranty. But OEM parts can be pricey and may be difficult to locate depending on your car’s age.

Aftermarket parts are a solid choice for older vehicles and for drivers looking to cut down on repair costs. They’re available in budget and premium options and are typically easier to find.

Where can I buy the parts for my AC compressor replacement?

If you plan to purchase OEM parts, you’ll have to visit your local dealership or contact an authorized parts supplier. You can buy aftermarket parts from most auto parts stores—like NAPA Auto Parts, Advance Auto Parts and AutoZone—or online retailers like Amazon and RockAuto.

How will a mechanic replace my AC compressor?

These are the general steps a mechanic will follow to replace your AC compressor:

Locate the compressor—it will be at the front of the engine bay with the other belt-driven engine accessories

Evacuate the AC system refrigerant—do not release the refrigerant into the atmosphere as it is illegal and extremely harmful to the environment

Loosen the serpentine belt tensioner and then remove the belt

Disconnect the compressor’s electrical connectors

Disconnect the compressor’s pressure hoses

Remove the mounting bolts from the compressor

Remove the old compressor

Prepare the new AC compressor by removing the dust caps and adding the specified amount and type of oil

Replace the o-rings on the pressure hoses

Position the new compressor and install the mounting bolts

Reinstall the pressure hoses

Reinstall the electrical connectors

Replace the serpentine belt and tighten the tensioner

Recharge the AC system

Start the car to ensure the system works properly and blows cold air

What happens if I don’t replace my AC compressor?

If you have a bad AC compressor and don’t replace it, you’ll likely face the following issues:

Loss of cooling ability: The primary symptom of a faulty compressor is a loss of AC cooling functionality. Warm air will blow through your vents, making driving uncomfortable during warm months.

Strain on other AC components: A bad compressor can lead to damage to other components, like the compressor clutch, serpentine belt, and pressure hoses.

Refrigerant leaks: A faulty compressor can cause refrigerant leaks. This will cause the system to perform even worse, in addition to being extremely harmful to the environment.

AC system contamination: It’s common for a failed AC compressor to shed metal particles or debris into the AC system. This can cause damage to other components, resulting in increased repair costs.

What is an AC compressor?

Your car’s air conditioner compressor is an integral part of the AC system. It’s responsible for compressing liquid refrigerant into gas and circulating that gas through the AC system.

The compressor sends high-pressure, high-temperature gas to the condenser, where it releases heat and returns to a liquid state. The liquid refrigerant then flows through an expansion valve or orifice tube, where it turns back into a low-pressure, low-temperature mixture of liquid and gas. From there, the refrigerant travels to the evaporator coil, absorbing heat from the cabin and cooling it before returning to the compressor, where the process starts again.

When should I replace the AC compressor in my car?

There are no set replacement intervals for AC compressors. In fact, your compressor may even last for your vehicle’s lifespan. That said, they can wear out over time, and you’ll need to replace yours when it fails.

Here are the most common signs of a faulty AC compressor:

Warm airflow from vents: The most common sign of a faulty compressor is a lack of cold air flowing from the vents.

Strange noises: A malfunctioning compressor can make strange noises, like grinding, rattling, squealing, or clunking sounds.

Delayed or intermittent cooling: If your AC system takes a long time to begin blowing cold air or the system works erratically, you may need a new AC compressor.

Refrigerant leaks: A damaged compressor can develop leaks. This can result in decreased cooling abilities.

Foul smells: A faulty compressor can release strange odors due to leaking refrigerant or a burned-out clutch.

Vibrations: If you notice vibrations from the engine bay while driving, it may be an indicator that you have a bad AC compressor.

The AC compressor clutch doesn’t engage: If the AC compressor clutch doesn’t engage when you turn on the AC system, it could be a sign of a bad compressor.

Keep in mind: These symptoms can indicate other HVAC issues, like a bad accumulator, a faulty condenser, or even a clogged cabin air filter. The best way to get an accurate diagnosis is to visit a certified mechanic.
