Knowing that your bad AC compressor needs a replacement and opting for a new part is not enough. You must carefully select a new compressor for your car’s air conditioning system in order to get the best out of the new component.

Here’s a well-detailed guide to help you choose the best car AC compressor for your vehicle. Ensure that the compressor you select passes through this six-step guide before making a buying decision.


Inasmuch as air conditioner compressors do not last very long for real due to the friction between their components, solid compressors in the market can serve a reasonable usage period.

You want to avoid splashing a lot of money on a new compressor only to return for another replacement within a short time. That’s why durability is one of the foremost factors to consider when choosing an AC compressor for your car.

So, ensure to check the material used in manufacturing the compressor and the specifications to ensure it conforms to the original equipment standard. 

Pay attention to the details of the various stringent durability and quality tests that the component was subjected to during the manufacturing process.

Vibration/noise level

How would you feel driving with a loud, disturbing noise or vibration from your car’s AC compressor? That experience can be frustrating, especially when the noise lingers long or remains indefinitely.

Some AC compressors are subjected to various stringent tests for quality, leaks, sound, and disruptive voltage checks to ensure the final output is excellent. 

Meanwhile, some compressors come charged with lubricant to minimize their noise during operation. So, it is vital to check for a compressor with a quiet and smooth operation before making a buying decision.

Lubricant type

AC compressors rely on refrigerant to function properly without any hassles. Meanwhile, the type of lubricant used in a compressor is a factor that determines the service life of the component.

While some air conditioner compressors from famous manufacturers come with already pre-filled refrigerant, others may not. When it comes to refrigerants, a good one should refrain from freezing or boiling during cold or hot weather conditions, respectively.

Therefore, you must carefully check for the recommended refrigerant for a particular AC compressor before you picking it up and paying.

Power usage

The air conditioning system derives its power from the vehicle’s engine. However, various cars have different voltage and power supplies for the HVAC system. In correlation, various AC compressors have unique voltage and power usage ratings.

That being said, it is crucial to inspect the specifications of the AC compressor you intend to buy, whether or not the voltage and power rating align with your car’s power supply capacity. This is because more powerful compressors consume a lot of power.

Nevertheless, virtually all the compressor manufacturers outlined in this review produce solid power-efficient air conditioner compressors.

In other words, the compressors from these brands deliver powerful but operate with minimal power consumption rates. This is a good one for your car battery’s health.

Ease of installation

Nowadays, car owners employ the DIY strategy to fix or replace faulty components in their cars to minimize costs. Hence, buying parts with a seamless installation process is something to consider.

The various air conditioner compressor brands listed above supply different car AC compressor types that are very easy to install, such that a beginner can handle the installation process without a professional. 

So, if you’re a DIYer, choosing a compressor with ease of installation would be an advantage as it will save you time and money. While this may not be a primary reason to buy a compressor, it is definitely an advantageous factor.


Sometimes, our buying decisions are regulated by the price of the item we intend to acquire. The same applies to buying a new replacement AC compressor. While some compressors have fantastic quality and performance capacity, they can be relatively expensive.

However, you can either go for brand new OE standard AC compressors or remanufactured AC compressors. No doubt, the brand new compressors are more expensive.

Nevertheless, some renowned manufacturers supply refurbished AC compressors with good quality and pocket-friendly prices. So, consider your budget before opting for a compressor for your car. 

Here’s a simple piece of advice: buy a brand new OE standard compressor at a relatively affordable price. Most of the AC compressor brands in this review manufacture relatively affordable parts, as their prices are usually lesser compared to the quality and efficiency of the compressors they offer.


How long do car AC compressors last?

Car AC compressors’ average lifespan is 10 – 12 years. However, a compressor can encounter an unexpected failure before this time frame. It is important to note that most vehicle AC compressors never attain their lifespan for different reasons.

Your maintenance style will go a long way to determining whether or not your car’s AC compressor will attain its expected service life. Meanwhile, replacing the component is the best way out if you experienced a compressor failure in your car.

What is the capacity of car AC compressor?

A car’s AC compressor capacity is 10 – 1000 CFM. Most passenger cars are built with an air conditioner compressor capacity of 1000 Cubic Feet per Minute (CFM) airflow at a pressure level of 2 bar and around 12 – 24 volts.

The importance of having an optimal AC compressor capacity level must be considered. A decline in the standard compressor capacity will alter the proper functionality of the component.

Is car AC compressor repairable?

Yes, you can repair a faulty car AC compressor if the problem is due to a minor external fault, such as a refrigerant leak or recharge hose won’t fit. This can cost around $160 – $1,000, depending on the extent of the fault and the type of vehicle.

While it is possible to fix slight malfunctions in automotive air conditioning compressors, there are more complicated internal faults that would necessitate a complete replacement of a bad compressor in some cases.

When should I replace my car compressor?

You must change your car’s air conditioner compressor when the component fails or breaks down. The compressor is a significant part of the HVAC system; hence, it must be replaced when faulty if the AC must work perfectly.

Otherwise, attempting to repair a bad compressor may end up as a waste of time and money because the repair may not be sustainable before the component breaks down again.


A bad AC compressor has various challenges that can sometimes be very frustrating. Therefore, if you have a damaged air conditioner compressor, replace the component as soon as possible.

Meanwhile, carefully follow the buying guide above to identify the best car AC compressor brand for your vehicle. Also, ensure to put your budget into consideration when choosing a particular compressor brand.

Nevertheless, replacing a compressor can be quite expensive, irrespective of your chosen brand. So, the main focus should be on going for a brand with high quality, durability, efficiency, and relatively affordable prices.
