How to Check Your Car’s AC Compressor: Keep Your Car Cool

“Hot as fire” is a common saying during the summer. Driving in Hanoi’s scorching heat without a functioning AC system is torture. The AC compressor, the heart of the cooling system, plays a crucial role. How can you tell if your car’s AC compressor is working properly? Let Xetaihanoi.edu.vn guide you through simple yet effective ways to check your car’s AC compressor in this article!

How to Check Your Car’s AC Compressor

1. Sensory Check

This is the simplest way to check the condition of your AC compressor.

• Sound: Start your car and turn the AC on full blast. Listen for any unusual noises coming from the AC compressor (usually located near the engine). If you hear strange sounds like whistling, hissing, or rattling, there might be a problem with the compressor.
• Feel: Place your hand on the low-pressure AC line (the larger diameter pipe). If it feels cold and has condensation, the compressor is likely working properly. Conversely, if the pipe is warm or not cold, the compressor may have a problem.

2. Check the AC Refrigerant Pressure

Refrigerant pressure directly impacts the AC’s cooling efficiency. You can purchase a refrigerant pressure gauge at auto parts stores or have a technician check it for you.

• Low Refrigerant Pressure: This could be due to insufficient refrigerant, a leak, or a malfunctioning compressor.
• High Refrigerant Pressure: This could be caused by a blockage in the system, a malfunctioning cooling fan, or overcharging the system with refrigerant.

3. Check Related Components

Besides the compressor, you should also check other components in the system:

• AC Compressor Belt: Check if the belt is loose, cracked, or broken.
• Condenser and Evaporator: Regularly clean the condenser and evaporator to ensure efficient cooling and prevent blockages.
• Cooling Fan: Ensure the cooling fan is working properly and not obstructed or damaged.
