How To Remove Freon From Car – Freon is a refrigerant that circulates in liquid and gaseous phases in the air conditioning unit and helps regulate the temperature of your car. The air conditioning system also helps prevent the car’s windows from freezing by maintaining the right temperature through the vents. Sometimes the AC system may not work properly due to the following reasons:
All these problems can only be diagnosed by removing the coolant from the car. So let’s learn how to drain the freon from the air conditioner in the car.
How To Remove Freon From Car
The most important thing you need to remove Freon from your car is an AC recovery device. This machine recycles and removes the refrigerant without any harm to the environment and also helps you refill the refrigerant.

Low and high pressure service ports provide pressure on the low and high side of the system. To access the low pressure service port, open the hood of the car and locate the low pressure port. It is usually located near the air conditioner compressor or supported by a firewall. Try to find a blue or black plastic removable cover. Also, you can follow the pipe coming from the compressor.
Once you have found the low pressure service port, connect it to the machine and turn it on. The machine would convert all liquid coolant into vapor form, reducing the pressure, and all other non-condensable vapors and gases would be removed from the air conditioning system. This process would take time and the machine will automatically shut down when all the refrigerant is removed from the system.
Also note that the machine can restart if system pressure starts to build, and will draw a vacuum until the system remains in this state for 10-15 minutes.
Congratulations! you learned how to remove freon from a car at home. Close the service hose valves and remove the hose from the fitting. Remember, the moment the low pressure valve reaches vacuum, turn off the compressor. This is very important to avoid damage to the compressor unit.

Engaging the compressor clutch is important. If it is not on and the pressure is less than 20 psi, let the coolant drain until it is stuck.
A pressure chart is available with the refill kit and would show you the exact amount of pressure to deliver at a given temperature. This is very important because too much or even too little coolant pressure is not safe for your car. Check the reading and fill until the desired pressure is reached. Also, shake the can often.
After charging the refrigerant to the desired pressure level, check for minor leaks. You will need a UV pen for this. Check each valve and connection and make sure you have fixed it.
Well, cars don’t take “cans” to fill your car. Cars built these days are so efficient that they only need a very small amount of refrigerant to cool your car. But one thing is important, even a small amount of additional refrigerant can cause a problem in the system, so be sure to follow the chart while charging the refrigerant and pour in the desired amount.

Before you start, it’s best to prepare. We recommend that you collect all materials, including the vacuum pump, protective gloves and the wrench.
We always recommend the use of gloves as Freon can be dangerous and it is best to avoid situations that could cause overexposure.
The first step you’ll take to get started is to make sure your car’s air conditioner is turned off so you can do this removal without too much of a safety risk while you’re working. The most important part you want to make sure is off before you start removing it is the car’s thermostat, including the heating and air conditioning systems.

The entire thermostat system should be completely turned off before starting the next step. Be sure to double-check the work you’ve done to make sure both systems are completely shut down. If you don’t, the removal process is much more difficult and dangerous.
With the heating and air conditioning system completely turned off, there is less chance that these systems will interfere with the work by having the liquid come into contact with your skin and cause irritation, as well as make a mess in the work area. All in all, this will help you prepare your workspace to do your work safely, efficiently and correctly. It’s easier to take these precautions up front than it is to clean up excess unnecessary clutter afterward.
A vacuum pump can now be connected and placed in the unit to remove all freon. We recommend waiting 5-10 minutes for the vacuuming to finish.
Once the suction appears to be complete, wait another 20-30 minutes and turn the pump back on. This will help you remove the excess left over from before.
