How to Remove Freon From Car Without a Recovery Machine
If you do not have a recovery machine, you can still recover freon. To do this you will have to condense the freon. All you need to do is to get a vacuum pump, HVAC manifold gauge with valves, hoses and couplers, and recovery tank with 1/4″ fitting, or you can use an empty cooking-gas tank. If you decide to use a cooking-gas tank, make sure it is empty then remove the original valve and screw in adapters, then a valve and a 1/4″ fitting. After getting all these, follow these steps to remove freon from your car without a recovery machine:
- Evacuate the recovery tank, hoses, and vacuum pump of any air to avoid it getting mixed with the freon.
- Ensure that the recovery tank is cold so that the freon can condense in it.
- Ensure that the car is not on and that it is cool.
- Make sure the low-pressure (blue) and the high-pressure (red) valves on the gauge and recovery tank are closed.
- Connect the low-pressure (blue) hose to the low-pressure side of the system located at the back of the compressor, near the firewall, and the high-pressure (red) hose to the high-pressure side of the system located in front of the radiator between the firewall and the condenser.
- Connect the service hose (yellow) to the vacuum pump, and then attach the vacuum pump line to the recovery tank.
- Slowly open the valves on the gauge and recovery tank and monitor the pressure to ensure that it does not exceed the normal freon pressure of about 15psi. With this, the freon should be released into the recovery tank.
- Once the low-pressure valve is empty, close the valves on the recovery tank.Overcharged Ac System Gauge Readings (How Do You Know If Your Car Ac Is Overcharged)

- Turn off the low-pressure (blue) and the high-pressure (red) valves on the gauge and recovery tank.
- Fasten the low-pressure (blue) hose to the low-pressure side of the system located at the back of the compressor, near the firewall, and the high-pressure (red) hose to the high-pressure side of the system located in front of the radiator between the firewall and the condenser.
- Connect the service hose (yellow) to the suction line of the recovery machine labeled ‘IN’, ‘INPUT’, or ‘INLET’ (depends on the brand of the machine you are using).
- Attach one end of the single hose to the discharge line of the recovery tank labeled ‘OUT’, ‘OUTPUT’ or ‘OUTLET’ (depends on the brand of the machine you are using), and the other end of the single hose to the recovery tank.
- Open all the valves on the gauge and the recovery tank then turn on the recovery machine.
- Once the valves are open, the freon will flow into the recovery tank. Watch the gauge to be sure that the freon doesn’t overfill the recovery tank.
- When the recovery machine is 0psi on the low-pressure side of the recovery machine, the machine will automatically go off. This means that the freon has been completed removed from the car.
- Close all valves, especially the one on the recovery tank.Do You Charge AC on The High or Low Side
When removing freon from a car, if the freon has not fully entered the recovery tank do not disconnect the hose to avoid releasing freon into the air.
