How To Remove Refrigerant From Car AC

There can be various reasons for removing refrigerant from the car AC. If you are searching a mechanic for removing the refrigerant from car AC, then search no further. You will be happy to know that you can easily remove the refrigerant from your own without anyone helps. It only requires several steps to remove the refrigerant. Even you will not need a lot of tools for this procedure. Keep reading this article to know how to remove refrigerant from car ac.

Precaution:  Refrigerant is mildly harmful. Breathing the air can cut the oxygen supply to your lungs and make it harder for you to breath. Moreover, if it comes in touch with your body skin, it can cause severe pain. So we advise you to be careful while dealing with the refrigerant. If possible, wear safety gloves, and goggles while removing the refrigerant from your car.

How To Remove Refrigerant From Car AC

Before you begin the procedure, you need to know whether the refrigerant is pure or not. It needs to be done to be assured whether you can reuse it or not. You can check with the help of the refrigerant purity status checker. It can be connected with your car’s AC service port and give you a reading based on the purity status. Make a container ready to discharge the refrigerant. The federal law also prohibits you from freeing the refrigerant in the air.

Here is how you will remove the refrigerant from the car’s AC. You will require a Wrench and a hex key for the procedure.

  • Turn off the indoor thermostat.
  • Find the suction side of the AC’s compressor as well as the low-pressure side of the refrigerant. The suction side is usually situated at the condensing unit. Now connect the suction side and the low-pressure side of the refrigerant.
  • Now use a wrench to close down the service valve which is situated at the low-pressure side of the condensing unit. If it’s hard to remove with the wrench, you can use the hex key.
  • Now close the service valve from the high-pressure side a little. Make sure you are not closing it entirely. Put the hex key back at its place.
  • After that, get to the compressor. Involve it with a low voltage jumper.
  • The low-pressure valve should gradually empty.
  • After a while, the low-pressure valve will become empty. Now close the valve directly.
  • De-energize the compressor, and you will be done.

It is essential to complete the final steps as quick as possible. Delaying during these steps may cause compressor damage. You can seek help from a buddy to quicker the project.

How To Remove Refrigerant From Car AC With Machine

Currently, there are digitalized machines which can remove the refrigerant, recycle it and make it reusable for your car’s AC. If you are going to use the machine, then follow the below process.

Step-1:  Attach the service hose of the machine to the ac system service port of your car. You will need to attach it in the low-pressure service port of the car. Follow the hose that runs from the back of the compressor to the accumulator near the firewall. In the backside of the compressor, the low-pressure bigger two lines are the low-pressure line. The high-pressure port is in between the firewall and the condenser of the high-pressure line. The capacitor is situated in front of the radiator. The high-pressure line is usually thicker than the low-pressure line.

Step-2:  Now start the machine. It will begin removing the refrigerant from the ac system. If there is any refrigerant in the system in liquid form, then the device will reduce the drop of the system. It will make the refrigerant to turn into vapor and come out from the system. If the system becomes empty, the machine will automatically shut off and monitor the pressure inside the system. If it rises, the machine will restart again and start removing the remaining. It will wait 5 to 10 minutes, and if the system stays at the empty state, then it will complete the process.

Disconnect the machine’s hose from the car’s AC system by removing it from the service port of the vehicle. Also, make sure to close the valves. Currently, most of the machine comes with a quick disconnect fitting, which is good for preventing refrigerant lose. In previous machines, you will need to shut off the port on the hose manually.

Removing the refrigerant from the car’s ac is not that. But it needs to be done precisely and carefully to avoid any issues. The above guide should be helpful for you to complete the process accurately.
