Repair for Adding Refrigerant:

The master of all auto AC repairs is the auto AC refrigerant that should suit the vehicle for the best. You can check the year of the refrigerant and you will find the correct type of refrigerant. Checking out the year is a useful method to choose the right refrigerant. Most of the vehicles are made after 1995 and all they use R134 a. If you have older than that you can use R12 easily. But you have to be informed that you cannot fill R12 yourself. You need to have an appointment with the AC repair service center to fill it up.

Check a Thermometer to Check the Ambient Temperature:

You need to know the current temperature of the environment if you want to read the gauge on the refrigerant. Auto air conditioning system can be at different temperature and refrigerant also occupies a different amount of space within the can. This can make the gauge of the refrigerant read at different temperatures.

Locate the Low Side Service Port:

An auto air conditioning system has always two sides, one is called the lower side port and the other is called the higher side port. When you need to charge your air conditioner system in your vehicle you always need to charge from the lower side service port. If you cannot locate the nozzle easily you may follow the compressor line to find out the lower side service port. You can also follow the manual book of your air conditioner to locate the service port.

Use a Rag to Clean the Service Port Area:

The lower service port of the auto AC system should be always neat and clean. You have to take care of this nozzle and make sure that it does not clog with any dirt or germ. You can use a brake cleaner to clean the line if you think this is better.

Attach the Service Hose to the Low Side Service Port:

You need to ensure the opposite side of the nozzle is being connected to the nozzle on the can. If you have a gauge one side of the hose should be connected to it and the other should be connected with the nozzle of the can. Make sure the hose is long enough to be connected with the nozzle on the gauge and also to the can.

Determine the Pressure:

Follow the chart of the ambient air pressure to know the actual air pressure. You need to read the display of the gauge so that you can know the ambient temperature amount to be considered. You have to know at what temperature level the refrigerant is now. Once you start spraying you have to keep an eye on the gauge to identify if the system is full.

Filling the Refrigerant:

You need to keep valuing the can until it begins to release the refrigerant. Some can may have different ways to break the seal of the can. You need to read the manual of the can carefully. Or you may take assistance from any auto specialist. You need to hold the can directly upright so that the refrigerant can pass through the vehicle’s engine.
