The Dangers of Removing Freon from Your Car Yourself

Don’t mess with your car’s AC yourself! There are big dangers you need to know about first.

Freon, also known as refrigerant, is a hazardous material that can cause serious health problems if inhaled or improperly handled.

Additionally, releasing freon into the environment contributes to climate change.

This article will explain why removing freon from your car without a recovery machine is dangerous and why seeking professional help is the safest course of action.

Why You Shouldn’t Remove Freon Yourself

Here’s why attempting DIY freon removal is a bad idea:

  • Health Risks: Freon exposure can irritate the lungs, eyes, and skin. Inhaling concentrated amounts can lead to respiratory failure or even death.
  • Environmental Damage: Freon is a potent greenhouse gas. Improper release contributes to global warming.
  • Legal Issues: Improper refrigerant handling may violate environmental regulations and lead to fines.

Safe Alternatives

Instead of risking your health and the environment, consider these safe alternatives:

  • Find a Certified Technician: Locate a qualified technician with the proper equipment and training to safely remove and dispose of freon. They can also diagnose and repair your AC system.
  • Mail-in Refrigerant Recycling Programs: Some companies offer mail-in services for used refrigerants. This ensures environmentally responsible disposal.

How to Remove Freon From Car Without Recovery Machine

It is advised to consult a professional to remove your freon from your car, however, if you still want to do it yourself, here are some steps to follow:

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

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.
