How To Purge Air From Car Ac System

Most car air conditioning systems have a refrigerant that needs to be periodically replaced. In addition the system will also need to be recharged with Freon periodically. Freon is a trade name for a group of refrigerants which include HFCs HCFCs and CFCs. Each type of Freon has its own specific characteristics.

When recharging the air conditioning system it is important to first check for leaks. Even a small leak can result in the loss of a large amount of Freon. Once any leaks have been repaired the system can then be recharged.

The first step in recharging the system is to connect the charging hose to the low-pressure service port. The low-pressure service port is usually located on the larger of the two hoses that connect to the air conditioner compressor.

Once the charging hose is connected open the valve on the can of Freon and hold the can upright. Slowly depress the trigger on the can until Freon begins to flow into the system.

As the system begins to fill you will likely hear the compressor cycle on and off. This is normal and simply indicates that the system is full.

Once the system is full turn off the valve on the can of Freon and disconnect the charging hose from the low-pressure service port. Close the hood of the car and start the engine.

Turn the air conditioner to the highest setting and let it run for a few minutes. This will help to distribute the Freon throughout the system.

After a few minutes turn off the air conditioner and open the hood of the car. Check the pressure in the system using the pressure gauge. The system is considered full when the pressure in the system is within the specified range for your particular vehicle.

If the system is not full repeat the steps above until the system is full. Once the system is full close the hood of the car and enjoy the cool air!
