How to Remove Freon From Car at Home

Is it time for you to remove the freon from your car? If you are worried about it, let me give you some good news! You can remove the freon from a vehicle at the comfort of home, and you do not have to be a mechanic to do it. However, you have to be careful.

 Learning about removing freon will help you to save time and money. The only required thing is an AC Recovery Machine which will recover and recycle the refrigerant. Once the machine runs a complete cycle, the cooling substance will be removed from your car.

Let's look at freon is and the step-by-step method to remove it.

 What is freon?

In simple words, freon is a fluid that alters between liquid and gas states to maintain the temperature of your car. People also call it a cooling substance or a refrigerant.

 Freon, in truth, is a brand name of refrigerant, but due to its popularity, the word freon has become synonymous with refrigerant.

How does the freon function

Freon is a fluid that cools the air in your car's air conditioner. The compressor in the AC converts the refrigerant from gas to liquid by applying pressure. Cool air is generated during this compression process, which the AC then throws out.

Step by Step Method To Remove freon From Car At Home:

 We already know that an AC Recovery Machine will be required to help you remove the freon by cycling the freon. Here are a few precautions to perform this process safely.

  • Protect your hands and eyes with protection gear (gloves and eyewear).
  • If possible, you can check the freon level in your car.
  • You will need help from someone else during the process.
  • Carefully turn the compressor off once the freon is removed.
  • The car should be off during the process.

Step 1: Locate the Low-Pressure Service Port

  • The first step is to locate the low-pressure service port, primarily on the bigger AC line between the condenser and evaporator. A blue or black plastic cap will help you identify the port.
  • To simplify things more, locate the compressor and follow the line to the evaporator, usually present under the windshield. The low-pressure port is not at the same spot in all vehicles; sometimes, it is located on the AC compressor.
  • After finding the low-pressure service port, connect the recovery machine's pipes to the service ports on the AC system.

Step 2: Start the Recovery Machine

  • After connecting the recovery machine to the low-pressure service port, the next step is to run the machine.
  • When the machine starts running, it will first remove the freon present in gaseous form in the AC system. The other part of freon, which is in liquid form, will take some time to be removed from the vehicle. To remove it, the machine will adjust to the pressure of the AC system and convert the liquid to gas.
  • The machine will stop automatically once all the refrigerant is removed.

Step 3: Turn Off and Disconnect the Recovery Machine

  • This is the final step, so make sure to close the server hose valves before disconnecting the machine.
  • Old machines used to remove R-12 freon need the valves on the hose to be closed.
  • In cases of R-134a freon, the machine has a quick detaching system.
