How did we estimate these prices?
Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

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

You should consult your vehicle’s repair guide or owner’s manual for detailed information about the AC system. Here’s a basic overview of the parts you may need

AC accumulator: The primary part you’ll replace is the AC accumulator. Prices can vary, but you should be able to pick up a new one for between $20 and $150.

O-rings: You may need to replace the accumulator’s o-rings if they’re broken or brittle. New ones can cost $5 to $20.

AC refrigerant: You may need to recharge the AC system with refrigerant after your AC accumulator replacement. Cans of refrigerant can cost between $20 and $50.

You can buy AC accumulator parts for your car from auto parts stores like AutoZone, NAPA Auto Parts, and Advance Auto Parts, as well as online retailers such as Amazon and RockAuto.

Three brands we recommend for a new AC accumulator are UAC (Universal Air Conditioner), Four Seasons, and ACDelco. For replacement O-rings, we recommend brands like Fel-Pro, Victor Reinz, and Mahle. And, when it comes to AC refrigerant, we recommend InterDynamics, A/C Pro, or FJC. Keep in mind that the best options for your suspension lubrication parts will vary depending on your’s year, make, and model.

Should I buy OEM or aftermarket parts?

Generally, you should opt for original equipment manufacturer (OEM) parts for automotive repairs—especially if you drive a newer car.

OEM parts are manufactured specifically to fit your vehicle. They come with a strong warranty and are made of high-quality materials. The downside to OEM parts is that they can be expensive and difficult to find.

Aftermarket parts, on the other hand, are usually cheaper and easier to find. They may be of lower quality but premium options are available. You can save money and lower your repair cost by buying an aftermarket part—just remember to check the part number to confirm it will fit your car.

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

For OEM parts, you’ll have to contact your local dealership or an authorized parts supplier. Aftermarket parts are available from various auto parts stores—like AutoZone, NAPA Auto Parts or Advance Auto Parts—and online retailers like RockAuto and Amazon.

How will a mechanic replace my AC accumulator?

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

Evacuate the refrigerant from the HVAC system

Locate the AC accumulator

Remove the lines connecting the AC system to the accumulator

Remove the old accumulator and bracket

Remove the old o-rings from the AC lines

Install new o-rings to the AC lines

Install the new AC accumulator and bracket

Connect the AC lines to the accumulator

Connect a vacuum pump to the AC system

Let the pump run for no fewer than five minutes

Turn off the pump and wait five more minutes

Remove the vacuum pump

Connect an oil injector to the system’s low-pressure side and fill the system with oil

Recharge the AC system with refrigerant

Start the car, turn on the AC system, and check to ensure that cool air is flowing

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

If you don’t replace a faulty AC accumulator, you’ll likely face the following problems:

Reduced cooling: The accumulator’s job is to remove moisture from the system. If it fails, moisture can enter the system, resulting in decreased efficiency and cooling.

Air conditioner compressor damage: A faulty accumulator may allow debris and contaminants to enter the compressor. This can cause damage and premature wear, leading to costly compressor repair or even the need for a new AC compressor.

Poor air quality: A faulty accumulator will allow contaminants, debris, and moisture into the air conditioning system. This will lead to bad smells and poor air quality.

AC system failure: A bad accumulator can result in blockages in the AC system. This can cause the entire system to fail.

Costly repairs: A faulty accumulator can lead to other AC system damage. This includes the air conditioning compressor, condenser, and evaporator coil.

What is an AC accumulator?

An AC accumulator—also known as a receiver-drier—is part of your car’s air conditioning system.

Automotive air conditioning systems have two sides: a high-pressure and a low-pressure side. The accumulator is located on the low-pressure side and is responsible for temporarily storing liquid refrigerant and removing moisture and debris from the refrigerant to protect the system from damage.

The AC accumulator is a metal canister that contains a desiccant. It plays a key role in maintaining the efficiency and proper functioning of the AC system.

When should I replace the AC accumulator on my car?

You should replace your AC accumulator if it fails or you open the AC system to perform repairs. The most common signs of accumulator failure include:

Rattling sounds during AC operation: One of the primary symptoms of a bad accumulator is a rattling sound during AC operation. This may indicate damage or corrosion inside the accumulator.

Noticeable refrigerant leaks: A failed accumulator may begin to leak refrigerant. If you notice pools of clear, oily liquid beneath the front of your vehicle, it could be a sign of AC accumulator failure.

Reduced cooling: If the accumulator goes bad, the AC system may struggle to produce cold air.

A foul smell when the AC is in use: If the accumulator allows moisture or contaminants to enter the AC system, you’ll likely notice a moldy smell coming from the vents.

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

How often do I need to replace my AC accumulator?

There is no set replacement interval for the AC accumulator, but there are two scenarios in which you should replace it: any time you open the AC unit for repairs and any time the accumulator fails.

Common signs of accumulator failure include a foul smell coming from the vents, a rattling sound, and noticeable refrigerant leaks.

Can I replace my AC accumulator myself?

An AC accumulator replacement can make a solid DIY project if you have the right know-how. It requires mid-level mechanical experience and access to basic tools. Moderately experienced home mechanics shouldn’t have any issues completing the project, but novices may be better off contacting a professional automotive HVAC technician.
