Things to know about an A/C Compressor

Auto Air Conditioning System

The air conditioning system in your car performs the vital role of cooling the air temperature in the cabin of your vehicle. Your A/C System should be checked and serviced every two years. Regular servicing of your A/C system will ensure optimal performance and could potentially save repair costs further down the track.

A basic rundown of how the A/C Compressor works

Your car’s air conditioning compressor is driven by the engine using a belt. Its function is to transport the refrigerant into the system. The refrigerant is subsequently sucked in as a gas at low pressure and then compressed to raise the temperature. From there, it is transferred to the condenser in the form of air with increased heat and force. The liquid becomes very cold as it leaves the condenser and returns to its natural gaseous state.

Effects of a Malfunctioning compressor

Reduced efficiency in your cars A/C System is often caused by a leak in the system, particularly in the A/C hoses. This is one of the most common reasons for an underperforming system. Low levels of refrigerant are responsible for reduced efficiency of the air conditioning system. Poor airflow due to an underperforming fan, blockage or debris in the A/C Condenser can also reduce the efficiency of the cooling in your A/C System. It is important to check the condenser for obstructions or damage. Regular maintenance can help reduce the need for repairs in the future.

Other common causes of a malfunctioning A/C compressor include a faulty magnetic Clutch. This is an extremely common fault which will stop an A/C Compressor from working. A defective Compressor control valve is also another common fault in many A/C Compressors. This can usually be determined by gauge readings.
