How to Remove Freon From Car Without Recovery Machine

What is Freon?

Freon is a refrigerant that helps to produce cold air through the air conditioning system in your car. The refrigerant goes through an ongoing evaporation process. It circulates through the system and absorbs heat from the engine to create cold air in air conditioning systems.

There are several uses for freon, some of which are more expensive than others, depending on product availability. The refrigerant levels are what people mean when they say an AC system needs to be recharged or replenished.

This fluid contains hydrogen, chlorine, or bromine and can be harmful when it circulates in the air or touches any of your body parts. Therefore, it should never be exposed to air for more than an hour, as its components are highly toxic.

How Do I Remove Freon From Car Without Recovery Machine?

To remove freon from your car without a recovery machine, you need a low-voltage jumper, a hex key, and a wrench.

However, before you proceed with the process, you must wear your nose mask, hand gloves, and safety goggles to protect your body.

Also, you need to know if the refrigerant you are about to remove is pure or impure, and you can do that with a purity detector. This will help you determine if you will reuse or dispose of it.

Here are the steps to remove refrigerant from a car without a recovery machine:

Step 1: Put Off the Cooling System

The thermostat in the car should be in the off position, so make sure it is. Both the heat and the air conditioning should be turned off. This will help make the process less complicated and safer.

Step 2: Locate the Suction Side

After you have put off the thermostat, cooling, and heating system, you would have to locate the suction side of your air conditioning compressor and the side with lower pressure. This port is usually located near the compressor of the air condition unit or backed by the firewall. 

Note that the low and high service ports help to provide pressure to the air conditioning system’s low and high-pressure sides.

Once you have located it, connect the suction to the low-pressure side and proceed to the next step.

Step 3: Ensure the Valve is Properly Closed

Use the wrench to turn the valves so that you can confirm that the valve on the unit’s low-pressure end is appropriately closed. 

A hex key can also do a great job here if you don’t have a wrench. So, you can use it to check the low and high pressure. However, ensure that the service valve on the high-pressure end is also slightly closed, don’t make it so tight.

Step 4: Connect to a Jumper

When you have confirmed the valves are closed, you can connect a low-voltage jumper to your compressor to drain the refrigerant. At this point, the low-pressure area will start draining as the valve gently releases air. 

When you have successfully removed the freon, you have to check to ensure that no fluid leaked into the high-pressure valve while the lower-pressure one was draining. After both valves are drained, you can close them tightly. 

Step 5: Dispose of the Freon Carefully

This is the last step after you have removed the freon. Carefully discard the freon if it’s not pure because it can be dangerous to people and the environment if not properly disposed of.

Make sure you don’t dispose of them carefully. You can get in touch with nearby companies that deal with chemicals of this nature. In most situations, they can also remove it for a bit of cost.

Safety Measures in Removing Freon in a Car

1. Wear Protective Clothing

Freons are harmful to the body. Therefore, before you remove the refrigerant from your car, you must wear safety clothing, work gloves, a nose mask, and safety goggles to protect yourself.

2. Stay in a Ventilated Environment

Refrigerant does not have to circulate in the air because it is harmful to the body. Inhaling freon can cause serious health issues, especially with your breathing. This is why you must always remove your freon in a well-ventilated environment.


1. Is it Safe to Remove Freon Without a Recovery Machine?

It is dangerous and not advised to remove the freon from an automobile without a recovery device. But if you follow the right precautions of removing refrigerant without a recovery machine and using safety equipment, it’s safe.

However, we advise you to consult a professional when dealing with chemicals like freon.

2. How Much Refrigerant is Required for a Car?

The amount of liquid freon required for a typical automotive air conditioning system is at most three pounds. 

3. Why Should Freon be Removed From a Car?

There are two major reasons you should remove the freon in your car. One of them is an old freon. 

If the freon in your automobile is old and deteriorating, it has to be removed. This is because it can result in problems such as corrosion or leakage.

Also, when your air conditioning system is leaking or is damaged, the removal of the freon will be necessary so the ac system can be fixed before you refill.
