It entails removing and disposing of any remaining refrigerant, disconnecting and removing the old compressor, installing the new one with proper fittings, and recharging with refrigerant. Add it all up and it typically takes four to six hours.

According to manufacturers, it typically has a 10- to 15-year life span. If the compressor is within or nearing its maximum age and suddenly breaks down, the damage is probably irreparable, and it would be best to replace the entire AC unit.

Overheating is a common cause of compressor failure, and there are many factors at play. If direct sunlight falls on your outdoor unit and there is inadequate ventilation around it, it makes your unit’s compressor overheated. High voltages can also damage the motor causing the compressor to overheat.

In some situations, technicians can repair your damaged compressor. However, if your compressor breaks down completely, it’s often safer and more cost-effective to replace the part. Many compressors come with a ten-year warranty, allowing for easy replacement.

Replacing an AC compressor is almost as simple as replacing any other accessory on your motor like the alternator or power steering pump. The biggest difference is that before you remove the actual compressor you have to remove the refrigerant lines connect to it.

Although the average lifespan of a car AC compressor is between 10 and 12 years, the compressor clutch could fail earlier than that. Unfortunately, a failed clutch means you need a whole new compressor—they’re inseparable.

After replacing the compressor, the A/C might not cool the car as expected. This could be due to improper vacuuming before recharging the refrigerant or a leak in the system. The solution is to check for leaks and ensure the system is properly vacuumed and recharged.
