Late May is a perfect time to be sure that your air conditioning is functioning properly and ready for the hot summer ahead. Even this convertible Porsche benefits from having functional A/C. Sure you can put the top down and enjoy nature’s wind induced air conditioning but sometimes it just gets too hot and a cool car is a real treat.

During our A/C service we: visually inspect the system for leaks; inspect the drive belt and pulleys for damage and wear; we then proceed to test the refrigerant and operation of the system. If there are leaks they must be diagnosed and fixed first. Some leaks however are very small or elusive. In this case it is best to recharge the system and add UV dye so as to facilitate finding the leak more easily at a later time.

On this 911 we performed an Evacuation and Recharge Service as no leaks were found during inspection. The air in the vehicle was crisp and cold after the service and testing of the system operating pressures confirmed that all was good.

A/C Service

A/C compressor with service hoses connected: these are the red and blue hoses. They allow us to test the system’s operating pressures. They are also used for evacuating and recharging the system. The A/C compressor is the round grey metal cylindrical part. The compressor clutch and pulley (black in colour) is attached along with the drive belt.
