No, you cannot. Unless you are a Section 608 certified technician, you should not attempt to remove Freon from a refrigerator or another appliance like an air conditioner.
A healthy car air conditioner requires a significant amount of power to function. Its power demand increases when there is too much Freon. In this situation, noises may come out from the drive belt.

How do you remove air from a refrigerator unit?
Follow the procedure below to remove air from the refrigeration system.
Change over the compressor to manual mode.
Now close the liquid stop valve after the condenser.
Pump the entire gas into the condenser by running compressor.
Stop the compressor when the suction pressure is just above zero.
How do you charge a refrigeration system with a receiver?
When the refrigerant leaves the receiver where does it flow next?
The refrigerant enters the evaporator as a cold, low pressure liquid, the refrigerant begins to boil and evaporate, this evaporation causes a cooling effect in the room and the heat is carried away to be dumped in the condenser after the compressor.
What is charging valve in refrigeration system?
A charging valve for refrigeration and HVAC systems comprises a valve body, a cap (with or without a gasket) and a valve core. The bodies of charging valves for refrigeration systems, most often made of brass, are available with or without a brazed copper tube.
Being a pure refrigerants, R134a, R12 and R22 can be charged either way. The blends like R401A, R409A, R410A and all in the 400 series of refrigerants must be charges as a liquid. The Azeotropes in the 500 series like R502 and R507 act nearly like pure refrigerants and can be charged either way as well.
Where is the liquid charging valve located?
A liquid charging valve is an access valve which is installed downstream of the King Valve. This location allows for some fancy maneuvering.

How long does Freon last in a car?
Most AC systems can last around five years without a Freon top-up, unless you live in a very hot climate. Freon is a kind of refrigerant that is recirculated in your vehicle in a closed system to cool down the interior. So, your car won’t really run out of Freon since it is reused inside the sealed system.
If you do not evacuate the system to remove air and moisture, you will reduce heat transfer capability through the refrigerant because air which is 78% nitrogen is not condensable in automobile systems. Moisture in an A/C only induces corrosion and more problems.
Does pulling a vacuum remove refrigerant?
Pulling vacuum from your cooling system removes refrigerants. However, only pull vacuum after recycling the refrigerant. Using the vacuum pump to pull refrigerants will only damage the pump. They’re only designed to evacuate moisture.
What happens if I don’t vacuum my AC?
Originally Answered: What happens if I don’t vacuum the AC system? You mean pull a vacuum on an air conditioning system for a few minutes? That would be bad. The air in the system gets in the way and the moisture will corrode things.
How long should you pull a vacuum on a car AC system?
So as many people wonder how long to vacuum AC system, the answer is 10-45 minutes. When concerned as to how long to vacuum AC system, you should know that usually it would take around 30-45 minutes if there is no leak in the pump. This is enough time period to get rid of moisture and dust inside the AC system.
How long should a AC system hold vacuum?
How Long Should You Pull a Vacuum On a Normal Compressor Change Out? To remove all of the air from your air conditioning system, you should give your vacuum at least 15 minutes and up to 30 to run at its maximum speed while it is functioning.
