    What to look out for when dealing with AC compressor issues Refrigerant is a dangerous chemical that can cause injury if improperly handled, and discharging into the atmosphere will cause damage to the ozone. Refrigerant is a dangerous chemical that can cause injury if improperly handled, and discharging into the atmosphere will cause damage to the ozone. If there has been an update or conversion from an older refrigerant type, a label should be placed under the hood to make your technician aware of the change. View repair cost for a different car.

    The air conditioning compressor is the heart of the air conditioning system. It moves refrigerant through the system, and compresses low pressure refrigerant to create high pressure refrigerant. The high pressure created is necessary for the air conditioning system to function and without it the air conditioner would blow just warmer than ambient temperature inside the vehicle.

    The compressor also uses check valves that allow refrigerant to flow in one direction. The compressor is necessary for the air conditioner to operate, and when it fails, the most common symptom is warm air from the vents. This may indicate that the compressor clutch is not functioning, or internal compressor failure has occurred.

    When the check valves fail, the high and low pressure sides of the refrigerant system may being to equalize in pressure, and the air conditioner may blow warmer air. Finally, a squealing or grinding noise may be heard from the compressor in the event of mechanical failure. In most situations a vehicle with a faulty air conditioning compressor is perfectly safe to drive. However, if grinding is heard from the compressor pulley, bearing failure may occur, causing the serpentine or drive belt to work its way off the pulley, and other necessary belt driven components.

    If this occurs, the battery warning light will illuminate, and the engine will stall due to lack of electrical power. Failure of the air conditioning compressor is common because moisture or clogs in the air conditioning system will place high stress on the compressor.

    Diagnosis of the air conditioning compressor requires advanced knowledge of air conditioning systems, and a good understanding of the relationship between temperature and pressure of a liquid and gas. A technician with proper training, and certification is required to repair an air conditioning system.

    Professional grade equipment is used to read high and low side pressure, and the technician must rely on hours of classroom and hands-on training to understand the readings and diagnose the faulty part.

    If the compressor is suspected to be faulty, the technician will ensure proper compressor clutch operation prior to diagnosing the compressor as the culprit. Replacement of most air conditioning components requires complete evacuation of the air conditioning system with refrigerant recovery machinery.

    Once all ozone depleting refrigerant is out of the system, the serpentine belt, refrigerant lines, and electrical connectors must be removed. Finally, the mounting bolts and hardware must be removed to allow the compressor to separate from the engine. Once those components are re-installed, the technician will remove all air from the system in preparation for recharging the system with new refrigerant. Refrigerant is environmentally harmful, and should never be released into the air.

    Instead, a proper refrigerant recovery machine must be used to protect the technician and the environment. Lastly, if your vehicle has not been converted from R12 to Ra refrigerant, the best time to have this service completed is when the air conditioning system is already being serviced.
