It contains a clutch that must engage and disengage properly. The compressor is a belt-driven accessory. The sounds could be whiny and robotic, with a consistent pitch. If parts have broken, you will only hear the sounds while the air conditioning system is on.

You will also need to factor in the refrigerant required as part of the cost of replacing a car air conditioner compressor. Depending on what vehicle you drive, you will have a different car air conditioner compressor cost than your neighbor’s vehicle. How much does an AC compressor cost for a car? You have more than the part to consider when determining the average car AC compressor replacement cost.įor starters, you must look at the compressor type and size. What Affects The Cost Of Car AC Compressor Replacement? Once the refrigerant is compressed, cooler air gets sent out of the air conditioning system. As the piston moves up and down in the cylinder, the pressure pulls the refrigerant in. It compresses and transfers the refrigerant through a cylinder and piston mechanism. The variable displacement compressor is also called a reciprocating compressor. Once the refrigerant is cooled, it exits the scroll along the outlet that’s part of the disk wall on the taller disk. The short disk rotation causes more gas to move into the center of the scroll, thereby compressing the gas. When the refrigerant gets suctioned, it will get trapped in these sealed sections. It also creates a sealed-up area with a certain amount of pressure. While the taller disk is stationary, the shorter one compresses the refrigerant while it rotates inside. The scroll AC compressor contains dual spiral disks that contain different heights.

With the pressure building up on one side, the cooled, compressed gas is moved out through the other side. Because the blade makes two areas that are sealed off, pressure builds up on both sides each time the roller moves. As the roller rotates within the cylinder, it passes through two sections that are divided by a spring-mounted blade. The rotary compressor utilizes a roller/cylinder mechanism.

Once the compression has occurred, the refrigerant is sent to the condenser, where it converts the heat into cooler air. On the high-pressure side, suction draws the refrigerant into the part for compression.

Your vehicle might use a rotary piston, scroll, or variable displacement compressor.Īll compressors contain two sections, both the high-pressure and low-pressure sides. However, different operations are used to compress the gas. It compresses and transfers refrigerant through the AC system. However, there are also different types of compressors that can affect the price.Īll compressors power the air conditioning system to work with the help of a belt assembly. How much does it cost to replace an AC compressor in a car? The cost to replace a car air conditioner compressor is usually around $1,000, depending on the factors discussed above.
